Hello to all…

..Isolated to scattered strong to severe thunderstorms are possible Monday Afternoon and Evening with a second round possible late Monday Night into early Tuesday Morning across much of interior Southern New England particularly in Southwest Rhode Island, Connecticut and Western and Central Massachusetts west of the I-495 corridor with strong to damaging winds, hail, frequent lightning and heavy rainfall with urban and poor drainage flooding as the main threats.
..The Storm Prediction Center (SPC) has continued the Marginal Risk for severe weather for Monday Afternoon and Evening for the area mentioned above which is a bit further west than last night’s message. The threat timeframe is anytime between 12-6 PM for the first round of activity with the second round timing a bit more uncertain and could be after 9 PM Monday Evening through about 7 AM early Tuesday Morning from a complex thunderstorms that will come in from the west and southwest and move east and northeast into Southern New England..
..SKYWARN Self-Activation will monitor the severe weather potential for Monday Afternoon and Evening and overnight self-activation ops are possible for the complex of thunderstorms moving in from the west and southwest into Southern New England..

A convective forecast with lower than normal confidence for the region as an upper level low continues to cause unsettled weather across Southern New England. Current Doppler Radar shows convective showers and thunderstorms in Southern New England and Southeast New York and this activity will continue through late afternoon/early evening. A few of these thunderstorms could be strong to severe. There will be a bit less heating than yesterday over the region but wind shear levels are slightly stronger. Heavy downpours and localized urban/poor drainage flooding is also possible.

After this activity, there could be a lull in the early evening hours and then a complex of strong to severe thunderstorms is expected across New York and the Mid-Atlantic states will spread into Southern New England during the late evening and overnight hours. This activity should be after 9 PM and maybe closer to the 12-1 AM through 7 AM timeframe. Typically, thunderstorms will lose their strength with loss of daytime heating but forcing, wind shear, what instability is left and possibly some cooling aloft from the thunderstorm complex may allow this complex to produce another round of isolated to scattered strong to severe thunderstorms across the region and this will be monitored.

SKYWARN Self-Activation will monitor the severe weather potential for Monday Afternoon and Evening and overnight self-activation ops are possible for the complex of thunderstorms moving in from the west and southwest into Southern New England. If time allows based on daytime and early evening operations, another coordination message will be posted by 11 PM Monday Evening on the overnight severe weather potential.

Hello to all..

..The following is the sixth and final in a series of messages on Amateur Radio Field Day Weekend and providing information on the weather during this period. This is a tradition spanning over 20 years for Amateur Radio Operators involved with Field Day and the NWS Boston/Norton SKYWARN Program..
..For Sunday, there remains a greater risk for isolated to scattered strong to severe thunderstorms with strong to damaging winds, hail, frequent lightning and heavy downpours as the main threats. The timeframe of severe weather potential has pushed a bit earlier and could start as early as 12 PM and continue through about 3-5 PM. This could now affect the last few hours and takedown of Field Day sites but again coverage will be isolated to scattered so some Field Day sites could see a thunderstorm but others will not see this activity. The area with the greatest potential is now from the Connecticut/Rhode Island/Mass border north into Northern New England but all locations should monitor..
..Any thunderstorms have lightning potential which is a safety hazard for all Amateur Radio Field Day sites. Amateur Radio Field Day sites are encouraged to guard their local Amateur Radio SKYWARN frequency and have multiple ways to receive weather alerts during the course of this Field Day weekend including by cell phone/Internet and NOAA Weather Radio..
..Conditions will be warm and very humid through Sunday. While there are low clouds and fog across Connecticut, Rhode Island and Southeast Massachusetts, that will burn off in these areas and there is already strong clearing and heating already occurring across Western, Central and Northeast Massachusetts. This will create greater instability and a better threat for thunderstorms with heavy rainfall and lightning hazards as well as isolated strong to severe thunderstorms..
..Temperatures Sunday will range between the Upper-70s to low 80s in coastal areas to the mid to upper 80s in interior areas and dewpoints in the low 70s will create very humid conditions. Be sure to drink plenty of liquids and guard against heat exhaustion especially during Amateur Radio Field Day setup and takedown..
..Amateur Radio Field Day Weekend is an annual event where Ham Operators across the United States setup at Emergency Operations Centers, field locations, home locations etc. to operate and test their equipment and skills and make as many radio contacts as possible during the weekend..
..SKYWARN Self-Activation will monitor conditions throughout Field Day weekend and activate as needed to guard Amateur Radio Field Day sites to provide weather information as well as to gather reports meeting SKYWARN reporting criteria throughout this weekend..

Here are some links to information on these Amateur Radio Field Day Sites from across the region.

For the remainder Amateur Radio Field Day weekend, the greatest risk for thunderstorms and isolated to scattered strong to severe thunderstorm potential will be Sunday from early Afternoon into Evening. The headlines of this message give the current thinking and coverage area. Key factors for Sunday include:

1.) Significant heating is already occurring in Western, Central and Northeast Massachusetts and this should spread into Connecticut, Rhode Island and Southeast Massachusetts as low clouds and fog burn off by mid-morning.
2.) Position of a trigger in the atmosphere to set off what should become an unstable atmosphere with the heating of the day. Right now that’s a weak front best positioned from around the Connecticut, Rhode Island, Massachusetts border and points north into Northern New England but all areas should monitor the thunderstorm potential.
3.) Wind shear values are low but amount of instability and the triggering mechanism may allow for isolated to scattered strong to severe thunderstorms and a greater coverage for non-severe thunderstorms with lightning risk. Thunderstorm coverage will be isolated to scattered so some Field Day sites could see a thunderstorm but others will not see this activity.

SKYWARN Self-Activation will monitor conditions throughout Field Day weekend and activate as needed to guard Amateur Radio Field Day sites to provide weather information as well as to gather reports meeting SKYWARN reporting criteria throughout this weekend.

Amateur Radio Field Day sites are encouraged to bring a NOAA All-Hazards Weather Radio, monitor various cell phone weather apps where Amateur Operators may have those available and have a dedicated Ham Radio that can monitor their local SKYWARN frequency for their area as a best safety and preparedness practice as there is a threat for thunderstorm development and any thunderstorm can be a threat to the safety of Amateur Radio Field Day sites. Also sites that have mobile Internet capability can utilize that capability as a way to monitor for weather information. With Mobile Internet capability, utilizing Echolink to monitor the New England Reflector system on Echolink Conference *NEW-ENG3* Node: 9123/IRLP 9123 would be helpful as well. Please see the link below for the latest SKYWARN Frequency information for the region:

Hello to all..

..The following is the fifth in a series of messages on Amateur Radio Field Day Weekend and providing information on the weather during this period. This is a tradition spanning over 20 years for Amateur Radio Operators involved with Field Day and the NWS Boston/Norton SKYWARN Program..
..2023 Field Day weekend, unlike the past few years, will have the potential for showers, thunderstorms and isolated severe weather. Not every Field Day site will see a shower, thunderstorm or severe weather and a widespread washout is not expected. Some Field Day sites could be dry all weekend but other Field Day sites could be quite wet depending on where showers and thunderstorms develop..
..Widespread rainfall amounts of a trace to 1″ occurred across Southern New England with isolated 1″+ amounts in portions of Southwest Massachusetts, North-Central Connecticut and Central Rhode Island per Amateur Radio and non-Amateur Radio SKYWARN Spotter reports..
..As of 545 PM Saturday Evening, Doppler Radar showed showers and heavier downpours were scattered across the North Shore of Massachusetts with lighter isolated showers in Central Massachusetts and Northern Connecticut. The threat for thunderstorms and any lightning hazards is minimal and will end after sunset and the current rain showers and isolated heavier downpours in the region will also wane after sunset as well. Any thunderstorm threat for the remainder of Saturday will be very isolated and severe weather is highly unlikely..
..For Sunday, there remains a greater risk for isolated to scattered strong to severe thunderstorms with strong to damaging winds, hail, frequent lightning and heavy downpours as the main threats with the timeframe of severe weather potential as Field Day ends around and after 2 PM and could affect the takedown of Field Day sites that take place after 2 PM through 9 PM Sunday Evening. The area with the greatest potential is across Western and Central Massachusetts, Northern Connecticut and Northwest Rhode Island but all locations in Southern New England should monitor..
..Any thunderstorms have lightning potential which is a safety hazard for all Amateur Radio Field Day sites. Amateur Radio Field Day sites are encouraged to guard their local Amateur Radio SKYWARN frequency and have multiple ways to receive weather alerts during the course of this Field Day weekend including by cell phone/Internet and NOAA Weather Radio..
..Conditions will be warm and very humid through Sunday. Temperatures will range between the mid-70s in coastal areas to the Upper 70s to mid 80s in interior areas depending upon how much heating occurs each day. Dewpoints in the low 70s will create very humid conditions. Be sure to drink plenty of liquids and guard against heat exhaustion especially during Amateur Radio Field Day setup and takedown..
..Amateur Radio Field Day Weekend is an annual event where Ham Operators across the United States setup at Emergency Operations Centers, field locations, home locations etc. to operate and test their equipment and skills and make as many radio contacts as possible during the weekend..

For the remainder Amateur Radio Field Day weekend, the greatest risk for thunderstorms and isolated to scattered strong to severe thunderstorm potential will be Sunday Afternoon and Evening with any isolated thunderstorm threat for Saturday ending after sunset. The headlines of this message give the current thinking and coverage area. Here is a breakdown of the hazards by each day:

Saturday Evening:
The headlines currently cover ongoing shower and isolated heavy downpour activity. The threat of a thunderstorm with lightning is low and will wane completely after sunset.

Sunday Afternoon and Evening:
This time period still has the higher severe weather potential as there will be more sun and daytime heating Sunday Morning through mid-afternoon which will heat things up more than on Saturday along with high humidity and that will allow for another round of showers and isolated to scattered strong to severe thunderstorms with strong to damaging winds, hail, frequent lightning and heavy downpours as the main threats as we get towards Sunday Afternoon and Evening around or after 2 PM as Field Day operations wind down and equipment takedown takes place. Again, the activity will be isolated to scattered and not all areas will see a shower or thunderstorm. The area with the greatest potential is across Western and Central Massachusetts, Northern Connecticut and Northwest Rhode Island but all locations in Southern New England should monitor.

SKYWARN Self-Activation will monitor conditions throughout Field Day weekend and activate as needed to guard Amateur Radio Field Day sites to provide weather information as well as to gather reports meeting SKYWARN reporting criteria throughout this weekend.

Some Field Day sites could be dry all weekend but other Field Day sites could be quite wet depending on where showers and thunderstorms develop..
..As of 830 AM Saturday Morning, showers and embedded thunderstorms are covering Western and Central Massachusetts and Rhode Island with the heaviest activity in Central Rhode Island in a north-south line moving Northeastward. This activity will spread into Eastern Massachusetts over the next 1-2 hours and will last through early afternoon. Following this activity, drier weather should occur starting late Morning in Western Massachusetts and Connecticut and spread eastward by early afternoon Saturday followed by additional but more isolated showers and thunderstorms for Saturday mid-afternoon thru early evening.
..Severe Weather potential is low for Saturday with frequent lightning and heavy downpours as the primary threat but if more instability develops than expected for Saturday afternoon, it would increase the severe weather potential. Regardless, any lightning in the vicinity of a Field Day site is a safety concern..
..For Sunday, there is a greater risk for isolated to scattered strong to severe thunderstorms with strong to damaging winds, hail, frequent lightning and heavy downpours as the main threats with the timeframe of severe weather potential as Field Day ends around and after 2 PM and could affect the takedown of Field Day sites..

For Amateur Radio Field Day weekend, unlike past years, there will be thunderstorm potential throughout the entire period particularly in the afternoon and evening period from Saturday to Sunday but some lightning hazard potential also exists for this Saturday Morning. The headlines of this message give the current thinking and coverage area. Here is a breakdown of the hazards by each day:

Saturday Morning through Saturday Evening:
The headlines currently cover ongoing shower and embedded heavier downpours and thunderstorm activity moving through Southern New England this Saturday Morning through early afternoon and how drier conditions will occur from west to east from late Saturday Morning through early Saturday Afternoon. More isolated showers and thunderstorms will be possible in the mid-afternoon through early evening before dissipating with the loss of daytime heating. The additional isolated showers and thunderstorms are conditional based on how much heating we get as this initial Saturday Morning shower and thunderstorm activity moves out of the region and if enough instability is generated with enough of a triggering mechanism for this activity to develop.

Sunday Afternoon and Evening:
This time period still has the higher severe weather potential as there will be more sun which will heat things up more than on Saturday and allow for another round of showers and isolated to scattered strong to severe thunderstorms with strong to damaging winds, hail, frequent lightning and heavy downpours as the main threats as we get towards Sunday Afternoon and Evening around or after 2 PM as Field Day operations wind down and equipment takedown takes place. Again, the activity will be isolated to scattered and not all areas will see a shower or thunderstorm. The Sunday Morning through early afternoon period is currently expected to be dry, warm and humid.

For Amateur Radio Field Day weekend, unlike past years, there will be thunderstorm potential throughout the entire period particularly in the afternoon and evening period from Saturday to Sunday. The headlines of this message give the current thinking and coverage area. Here is a breakdown of the hazards by each day:

Late Friday Night through Saturday Evening:
Thunderstorms are possible anywhere in Southern New England with the greatest coverage and strongest thunderstorms from the I-95 corridor north and west throughout interior Southern New England. It appears there could be showers and embedded thunderstorms late Friday Night into Saturday Mid-Morning followed by a break and the more showers and thunderstorms occurring Saturday afternoon and evening. The coverage will be more numerous than Friday but again not a washout across the region. Some areas and field day sites may be impacted by showers and thunderstorms with heavy rainfall while other locations could receive no rainfall. Cloud cover is expected to keep instability levels lower and the severe weather potential is now low for Saturday but any thunderstorms with lightning are a safety hazard for Field Day sites and if there is more heating during the day, it would increase the severe weather potential. The activity could be slow moving which would also cause localized flooding in areas where thunderstorms train over the same area though latest guidance shows thunderstorms moving more quickly than in previous forecasts. This will all bear close monitoring given Saturday is the more active of the 2 days of Amateur Radio Field Day weekend.

Sunday Afternoon and Evening:
This time period now has higher severe weather potential as there will be more sun which will heat things up more than on Saturday and allow for another round of showers and isolated to scattered strong to severe thunderstorms with strong to damaging winds, hail, frequent lightning and heavy downpours as the main threats as we get towards Sunday Afternoon and Evening around or after 2 PM as Field Day operations wind down and equipment takedown takes place.

SKYWARN Self-Activation will monitor conditions throughout Field Day weekend and activate as needed to guard Amateur Radio Field Day sites to provide weather information as well as to gather reports meeting SKYWARN reporting criteria throughout this weekend. Below are links to the NWS Boston/Norton Area Forecast Discussion, Hazardous Weather Outlook and Enhanced Hazardous Weather Outlook:

Hello to all..

..The following is the second in a series of messages on Amateur Radio Field Day Weekend and providing information on the weather during this period. This is a tradition spanning over 20 years for Amateur Radio Operators involved with Field Day and the NWS Boston/Norton SKYWARN Program..
..2023 Field Day weekend, unlike the past few years, will have the potential for showers, thunderstorms and isolated severe weather. Not every Field Day site will see a shower, thunderstorm or severe weather and a widespread washout is not expected. Some Field Day sites could be dry all weekend but other Field Day sites could be quite wet depending on where showers and thunderstorms develop..
..With the thunderstorms, a few of them could be strong to severe with strong to damaging winds, hail, and heavy downpours leading to urban and poor drainage flooding. The severe weather potential remains focused on Saturday and Sunday Afternoon and Evening though some showers and isolated thunderstorms may occur late Friday Night into Saturday Morning making any shower and thunderstorm redevelopment Saturday Afternoon and Evening more uncertain..
..Any thunderstorms have lightning potential which is a safety hazard for all Amateur Radio Field Day sites. Amateur Radio Field Day sites are encouraged to guard their local Amateur Radio SKYWARN frequency and have multiple ways to receive weather alerts during the course of this Field Day weekend including by cell phone/Internet and NOAA Weather Radio..
..Conditions will be warm and very humid Friday through Sunday. Temperatures will range between the mid-70s in coastal areas to the Upper 70s to mid 80s in interior areas depending upon how much heating occurs each day. Dewpoints in the low 70s will create very humid conditions. Be sure to drink plenty of liquids and guard against heat exhaustion especially during Amateur Radio Field Day setup and takedown..
..Amateur Radio Field Day Weekend is an annual event where Ham Operators across the United States setup at Emergency Operations Centers, field locations, home locations etc. to operate and test their equipment and skills and make as many radio contacts as possible during the weekend..
..SKYWARN Self-Activation will monitor conditions throughout Field Day weekend and activate as needed to guard Amateur Radio Field Day sites to provide weather information as well as to gather reports meeting SKYWARN reporting criteria throughout this weekend..

Here are some links to information on these Amateur Radio Field Day Sites from across the region.

For Amateur Radio Field Day weekend, unlike past years, there will be thunderstorm potential throughout the entire period particularly in the afternoon and evening period from Friday to Sunday. For Friday, thunderstorms main potential hazards to Field Day sites will be heavy downpours and frequent lightning. On Saturday and Sunday, the thunderstorm potential is increased with the potential for isolated to scattered strong to severe thunderstorms in addition to heavy downpours and frequent lightning though the Saturday potential for severe weather is more uncertain now due to the potential for showers and thunderstorms late Friday night into Saturday Morning which may produce more cloud cover during the afternoon and evening possibly mitigating the severe weather potential for Saturday Afternoon and Evening. It will be warm and very humid during the weekend. The headlines of this message give the current thinking and coverage area. Here is a breakdown of the hazards by each day:

Friday Afternoon and Evening:
Thunderstorms can occur particularly in Western and Central Massachusetts and Connecticut with heavy downpours and frequent lightning. Doppler Radar shows an area of showers over south of Long Island that could move into Connecticut and Western and Central Massachusetts during the afternoon if they hold together with embedded non-severe thunderstorms possible. Additional showers and isolated thunderstorms may form ahead of that rain area. The threat of severe weather is minimal and coverage of showers and thunderstorms will be isolated to scattered in nature and will be monitored.

Late Friday Night through Saturday Evening:
Thunderstorms are possible anywhere in Southern New England with the greatest coverage and strongest thunderstorms from the I-95 corridor north and west throughout interior Southern New England. It appears there could be showers and thunderstorms late Friday Night into Saturday Morning followed by a break and more showers and thunderstorms occurring in the afternoon and evening. The coverage will be more numerous than Friday with the potential for isolated to scattered strong to severe thunderstorms but if there is activity during Saturday morning, cloud cover could reduce instability and reduce the severe weather potential but this will be monitored. The activity could be slow moving which would also cause localized flooding in areas where thunderstorms train over the same area though latest guidance shows thunderstorms moving more quickly than in previous forecasts. This will bear close monitoring given Saturday is the more active of the 2 days of Amateur Radio Field Day weekend.

Sunday Afternoon and Evening:
This time period may now have higher severe weather potential as there could be more sun which could heat things up more than on Saturday and allow for more coverage of showers and isolated to scattered strong to severe thunderstorms as we get towards Sunday Afternoon and Evening as Field Day operations and equipment takedown takes place. Further details on Sunday’s weather will be given in the Friday Evening and Saturday coordination messages.

SKYWARN Self-Activation will monitor conditions throughout Field Day weekend and activate as needed to guard Amateur Radio Field Day sites to provide weather information as well as to gather reports meeting SKYWARN reporting criteria throughout this weekend.

Amateur Radio Field Day sites are encouraged to bring a NOAA All-Hazards Weather Radio, monitor various cell phone weather apps where Amateur Operators may have those available and have a dedicated Ham Radio that can monitor their local SKYWARN frequency for their area as a best safety and preparedness practice as there is a threat for thunderstorm development and any thunderstorm can be a threat to the safety of Amateur Radio Field Day sites. Also sites that have mobile Internet capability can utilize that capability as a way to monitor for weather information. With Mobile Internet capability, utilizing Echolink to monitor the New England Reflector system on Echolink Conference *NEW-ENG3* Node: 9123/IRLP 9123 would be helpful as well. Please see the link below for the latest SKYWARN Frequency information for the region:

Hello to all…

..A general soaking rainfall is expected across Southern New England late Friday Night through Saturday Night with improving conditions for Sunday. A general rainfall of 0.50-2.00″ of rain in the region is likely across Southern New England with portions of Rhode Island and Southeast Massachusetts seeing localized amounts of 2-3″+ depending on if heavier downpours and embedded thunderstorms train over a given area. This rainfall may cause localized urban and poor drainage flooding in areas that receive the highest rainfall amounts..
..SKYWARN Self-Activation will monitor for rain gauge and any flooding reports later tonight and especially Saturday. This will be the only coordination message unless a significant upgrade to the situation occurs and time allows for an update. Below is the NWS Boston/Norton Area Forecast Discussion, Enhanced Hazardous Weather Outlook and Rainfall Infographic..

Hello to all…

..Isolated to Scattered Strong to Severe Thunderstorms remain possible Wednesday Afternoon and Evening in Western and Central Massachusetts, Northwest Rhode Island and Connecticut anytime between 2-9 PM Wednesday with strong to damaging winds, hail, frequent lightning and heavy rainfall with the potential for localized urban and poor drainage flooding as the main threats. The Storm Prediction Center (SPC) has continued this area in a marginal risk for severe weather for Wednesday Afternoon and Evening..
..SKYWARN Self-Activation will monitor the severe weather potential for Wednesday Afternoon and Evening..

An upper level Low pressure system will move into Southern New England as we get into mid to late afternoon and early evening. The upper level low will bring cooling temperatures aloft and marginally sufficient wind shear for isolated to scattered strong to severe thunderstorms. The headlines depict the current thinking. Key factors include:

1.) The timing of the cooling aloft with max heating of the day or the degree the cooling aloft can offset loss of heating if that cooling occurs past the time of peak heating.
2.) The forcing and trigger mechanisms from the upper level low reaching our area of Southern New England near the time of peak heating to allow for strong to severe thunderstorm development.

SKYWARN Self-Activation will monitor the severe weather potential for Wednesday Afternoon and Evening. This will be the last coordination message as we move into operations mode unless a significant upgrade to the situation occurs and time allows for an update.
