Hello to all…

..Isolated to Scattered Strong to Severe Thunderstorms are likely today across Western Massachusetts potentially as far east as Worcester County Mass and across Connecticut. Strong to damaging winds, hail, frequent lightning, and heavy downpours with the potential for urban and poor drainage flooding are the main threats. The Storm Prediction Center (SPC) has placed this area in a marginal risk for severe weather. Threat timeframe is highest between 4-8 PM but a few isolated strong to severe thunderstorms could form as early as 2 PM..
..SKYWARN Self-Activation will monitor severe weather potential for this Saturday Afternoon and Evening in Western Massachusetts and Connecticut..

With the remnants of Fay north and west of us into Canada, satellite imagery shows reasonably good clearing across the area with a trigger and impulse in the atmosphere across Western Pennsylvania into Central New York. The headlines depict the latest thinking. The key factors on the severe weather potential is as follows:

1.) Timing of the trigger in the atmosphere to set off the high level of instability during the afternoon and early evening to cause strong to severe thunderstorm development across Western Massachusetts and Connecticut.
2.) Ability of the trigger and impulse in the atmosphere to overcome marginal shear profiles to allow for strong to severe thunderstorm development for later this afternoon and evening.

SKYWARN Self-Activation will monitor severe weather potential for this Saturday Afternoon and Evening in Western Massachusetts and Connecticut. This will likely be the only coordination message on the Saturday severe weather potential as we shift to monitoring and operations mode.

Hello to all…

..Tropical Storm Fay has strengthened slightly as it continues to move northward. Track confidence has increased in a track along the New Jersey Coast and into the New York City area and through Eastern New York/extreme Western New England. Fay will bring heavy rainfall and possible flash flooding to western portions of Southern New England, the threat of isolated severe thunderstorms and to a lesser extent, the possibility of strong winds particularly along South Coastal Rhode Island and South Coastal Massachusetts.
..Tropical Storm Warnings are in effect from Watch Hill Rhode Island westward across coastal Connecticut and Long Island New York..
..A Flash Flood Watch remains in effect for Northern Connecticut and Hampden, Hampshire and Franklin Counties of Western Massachusetts from 12 PM Friday Afternoon through Saturday Morning. A general 1-2″ rainfall is likely but higher amounts could occur in a portion of the flash flood watch area which could lead to flash flooding of urban areas and small streams..The Flash Flood Watch for the rest of the NWS Boston/Norton coverage area is canceled with rainfall of 0.50-1.5″ with isolated higher amounts possible..
..The Storm Prediction Center (SPC) has placed portions of Connecticut, Rhode Island, South-Central and Southeast Massachusetts in a Marginal Risk for severe weather for Friday Afternoon into Friday Night for isolated severe thunderstorm potential which could have strong to damaging winds and possibly an isolated weak tornado. A Slight Risk for severe weather exists for South Coastal Connecticut into extreme southwest coastal Rhode Island as well..
..SKYWARN Self-Activation will monitor the progress of Tropical Storm Fay with the impacts from Fay late Friday Afternoon into Saturday Morning..

Tropical Storm Fay is strengthened slightly as heads towards the Northeast US coast. Tropical Storm Fay will move swiftly up the coast affecting our region’s weather late Friday Afternoon into Saturday Morning. The headlines depict the latest thinking. Key factors with Tropical Storm Fay include:

1.) Heavy rainfall with the potential of urban/poor drainage flooding to flash flooding and the possibility of an isolated severe thunderstorm or two capable of a wet microburst or an isolated tornado are the main threats for the NWS Boston/Norton coverage area from Fay. With the current track guidance remaining stable, the heaviest rain is expected to be in Western Massachusetts and Northern Connecticut so the Flash Flood Watch remains in effect there but is canceled for the rest of the NWS Boston/Norton coverage area.
2.) Right now, the track of Fay will be hugging the US east coast and model runs continue to indicate that track. This will keep the strongest winds confined to the Tropical Storm Warning area. The chance of a track further east is now less likely though will still be monitored. That said, parts of south coastal Rhode Island and South Coastal Massachusetts could see wind gusts between 30-40 MPH with isolated higher gusts as Fay moves swiftly through the area.

SKYWARN Self-Activation will monitor the progress of Tropical Storm Fay with the impacts from Fay late Friday Afternoon into Saturday Morning. This will be the last coordination message on Fay unless a significant upgrade to the situation occurs and time allows for an update as we shift into operations mode.

Hello to all…

..Tropical Storm Fay has formed off the coast of North Carolina and has the potential to bring heavy rainfall and possible flash flooding to portions of Southern New England that will depend on the strength and intensity of Fay, the threat of isolated severe thunderstorms and to a lesser extent, the possibility of strong winds particularly along South Coastal Rhode Island and South Coastal Massachusetts. Tropical Storm Warnings are in effect from Watch Hill Rhode Island westward across coastal Connecticut and Long Island New York..
..A Flash Flood Watch is now in effect for the entire NWS Boston/Norton Coverage Area for Friday Afternoon into Saturday Morning. A general 1-2″ rainfall is possible but higher amounts could occur in a portion of the flash flood watch area which could lead to flash flooding of urban areas and small streams..
..The Storm Prediction Center (SPC) has placed portions of Connecticut, Rhode Island, South-Central and Southeast Massachusetts in a Marginal Risk for severe weather for Friday Afternoon into Friday Night for isolated severe thunderstorm potential which could have strong to damaging winds and possibly an isolated weak tornado..
..SKYWARN Self-Activation will monitor the progress of Tropical Storm Fay with the impacts from Fay late Friday Afternoon into Saturday Morning..

The area of disturbed weather off the North Carolina coast has developed into Tropical Storm Fay. Tropical Storm Fay will move swiftly up the coast affecting our region’s weather late Friday Afternoon into Saturday Morning. The headlines depict the latest thinking. Key factors with Tropical Storm Fay include:

1.) Heavy rainfall with the potential of urban/poor drainage flooding to flash flooding and the possibility of an isolated severe thunderstorm or two capable of a wet microburst or an isolated tornado are the main threats for the NWS Boston/Norton coverage area from Fay.
2.) Right now, the track of Fay will be hugging the US east coast. This would keep the strongest winds confined to the Tropical Storm Warning area. There is a chance of a track slightly further east which would allow Fay to affect parts of the South Coast of Rhode Island and Massachusetts with stronger winds as models initialized the storm a bit further south and west then where the center of Fay was detected by recon aircraft. Trends in models will be monitored regarding the track of Fay.

SKYWARN Self-Activation will monitor the progress of Tropical Storm Fay with the impacts from Fay late Friday Afternoon into Saturday Morning. Another coordination message will be posted by 8 AM Friday Morning.

Hello to all…

..Isolated to Scattered Strong to Severe Thunderstorms are likely across Western, Central and Northeast Massachusetts and Northwest and North-Central Connecticut Wednesday Afternoon and Evening, strong to damaging winds, hail, frequent lightning and heavy downpours leading to urban and poor drainage flooding to flash flooding are the main threats..
..The Storm Prediction Center (SPC) has continued a Marginal Risk for Severe Weather for Western, Central and Northeast Massachusetts and Northwest and North-Central Connecticut for Wednesday. It is noted that much of New Hampshire and Southern Maine are in a slight risk for severe weather. The threat timeframe for severe thunderstorms could be as early as 1 PM Wednesday but the most likely time range is now between 4-10 PM Wednesday..
..SKYWARN Self-Activation will monitor the severe weather potential for Wednesday Afternoon and Evening..

Not much change to the headlines regarding severe weather potential for Wednesday. The key factor for severe weather on Wednesday remains how far south an impulse in the atmosphere will get to serve as a triggering mechanism for strong to severe thunderstorms within our coverage area. There will be sufficient heating and destabilization with marginally sufficient wind shear to support strong to severe thunderstorm development. Some of the storms may have slow movement which may allow for urban and poor drainage flooding to flash flooding to occur with some of these storms. It is noted that with this update much of New Hampshire and Southern Maine have been upgraded to a slight risk for severe weather where the impulse is tracking into that area more directly so the risk to northern and western portions of Southern New England will hinge on that impulse trigger affecting northern and western portions of Southern New England and if its far enough south to do so.

SKYWARN Self-Activation will monitor the severe weather potential for Wednesday Afternoon and Evening. Below is the NWS Boston/Norton Hazardous Weather Outlook, Enhanced Hazardous Weather Outlook and SPC Day-1 Convective Outlook:

Hello to all…

..Isolated to scattered strong to severe thunderstorms are likely Sunday afternoon and evening particularly over Northeastern and Central Massachusetts and into North-Central Rhode Island but the potential could extend southwest back into parts of Western Massachusetts and North-Central and Northeast Connecticut. Strong to damaging winds, hail, frequent lightning and heavy rainfall leading to urban and poor drainage flooding are the primary threats but an isolated tornado is a secondary threat..
..The Storm Prediction Center (SPC) has extended the Marginal Risk into Northeast Connecticut, Rhode Island and the Connecticut River Valley of Western Massachusetts east into Central and Eastern Massachusetts for today. Severe weather potential timeframe is between about 2-10 PM Sunday Afternoon and Evening..
..SKYWARN Self-Activation will monitor the severe weather potential for Sunday Afternoon and Evening..

..It has been an active week for severe thunderstorms and localized flooding across parts of Southern New England. A Post Severe Weather Coordination Message will be posted on the various events from the week of 6/28 later this Sunday Morning ahead of today’s severe weather if time allows..

There remains the potential for severe weather on Sunday Afternoon and Evening and the marginal risk for severe weather has been expanded southwestward and westward into parts of North-Central Connecticut, Rhode Island and Western Massachusetts from the Connecticut River Valley east into Central and Eastern Massachusetts. The headlines depict the current thinking. Key factors include:

1.) The level of mid-level dry air in the atmosphere and whether too much of dry air stunts severe thunderstorm development. At this time, this is expected to be overcome particularly from the Connecticut River Valley eastward with the most favorable area in Northeast Massachusetts. There will be a sharp cutoff between higher and lower dewpoint air that will setup in Central New England and areas along and to the east of that higher/lower dewpoint air line will see the greatest risk for severe weather development.
2.) The level of forcing or a trigger in the atmosphere to take advantage of the favorable instability and wind shear profiles in the atmosphere or whether the level of instability and wind shear compensates for a marginal trigger or forcing in the atmosphere. A cold front will move into the area along with the line between higher and lower dewpoint air towards evening which will set the area for the most favorable conditions for severe weather potential.
3.) There is the possibility for two rounds of activity. One in Western and Central Massachusetts and Northern Connecticut spreading eastward between 3-6 PM with another round after 6 PM to 10-11 PM that would be focused in Northeast Massachusetts but other areas should monitor.

SKYWARN Self-Activation will monitor the severe weather potential for Sunday Afternoon and Evening. This will be the last coordination message as we shift into operations mode.

Hello to all…

..Happy Independence Day and July 4th to all SKYWARN Spotters and Amateur Radio Operators. We hope you’re all enjoying the holiday..
..Isolated to scattered strong to severe thunderstorms are possibly to likely Sunday afternoon and evening particularly over Northeastern and Central Massachusetts and into North-Central Rhode Island but the potential could extend southwest back into Western Massachusetts and Northern Connecticut depending if the more favorable conditions can extend back further west. Strong to damaging winds, hail, frequent lightning and heavy rainfall leading to urban and poor drainage flooding are the primary threats but an isolated tornado is a secondary threat..
..The Storm Prediction Center (SPC) has placed Eastern and Central Massachusetts and Northeast Rhode Island in a marginal risk for severe weather Sunday and indicated a potential expansion of the risk further west into other parts of Southern New England and as far west as Eastern New York in future outlooks. Severe weather potential timeframe is between about 1-10 PM Sunday Afternoon and Evening..
..SKYWARN Self-Activation will monitor the severe weather potential for Sunday Afternoon and Evening..

..It has been an active week for severe thunderstorms and localized flooding across parts of Southern New England. A Post Severe Weather Coordination Message will be posted on the various events from the week of 6/28 this Saturday Evening. We are also looking for any post storm damage reports and photos to add to existing and new photo albums on the Facebook page. They can be posted on our WX1BOX Facebook/Twitter feed or to the email address pics@nsradio.org with date and location information and credit will be given to the spotter unless otherwise indicated..

We hope everyone is enjoying their July 4th. There is the potential for severe weather on Sunday Afternoon and Evening, particularly in Central and Northeast Massachusetts and into Northeast Rhode Island but could extend back southwest into Western Massachusetts and Northern Connecticut. The headlines depict the current thinking. Key factors include:

1.) The level of mid-level dry air in the atmosphere and whether too much of dry air stunts severe thunderstorm development. At this time, this is expected to be overcome particularly from Worcester and Providence and points north and east on most models but some models bring the potential all the way through Western Massachusetts and Northern Connecticut and into Eastern New York.
2.) The level of forcing or a trigger in the atmosphere to take advantage of the favorable instability and wind shear profiles in the atmosphere or whether the level of instability and wind shear compensates for a marginal trigger or forcing in the atmosphere.

SKYWARN Self-Activation will monitor the severe weather potential for Sunday Afternoon and Evening. Another coordination message will be posted by 10 AM Sunday Morning. Below is the NWS Boston/Norton Hazardous Weather Outlook, Enhanced Hazardous Weather Outlook and SPC Day-2 Convective Outlook:

Hello to all..

..The following is the fifth and final message 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 17 years for Amateur Radio Operators involved with Field Day and the NWS Boston/Norton SKYWARN Program..
..After the Saturday afternoon and early evening beneficial rain of around 0.10″-0.90″ around the area with lesser amounts in parts of Northeast Massachusetts, Sunday will feature a warm and humid day with the potential for isolated to scattered strong to severe thunderstorms across the region. The most likely timeframe is from 3-9 PM but some activity could start as early as 12-1 PM Sunday..
..The Storm Prediction Center (SPC) has upgraded much of Southern New England to a slight risk of severe weather with a marginal risk for severe weather from the cape cod canal east through Cape Cod and the Islands for Sunday afternoon and evening. Strong to damaging winds, hail, and torrential rainfall leading to urban and poor drainage flooding are the main threats. Model trends continue to indicate a greater potential for severe weather on Sunday than today with strong instability, forcing from a cold front and marginally sufficient wind fields..
..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. Due to COVID-19, Amateur Radio Field Day across Southern New England will be quite different with far less Field Day sites than normal in the region and those that are up and running in the field adhering to social distancing guidelines with limited to no public access. There will be many more Amateur Radio Field Day operations operating at home and not at field locations. Amateur Radio Field Day resource information is listed below..
..SKYWARN Self-Activation will monitor conditions throughout Field Day weekend with Amateur Radio Call Up Nets brought up as required..

Here are some links to information on these Amateur Radio Field Day Sites from across the region understanding limited to no public access in 2020 due to COVID-19 restrictions and far less field day sites than normal years:

ARRL President K5UR-Rick Roderick’s Field Day 2020 Statement: http://www.arrl.org/news/arrl-president-rick-roderick-k5ur-issues-field-day-2020-statement

Severe weather for Saturday was squelched by the warm front remaining along the south coast of New England today resulting in an area of light to moderate rain occurring across much of southern New England during the mid-afternoon to early evening hours bringing a beneficial 0.10″-0.90″ to much of Southern New England with lesser amounts in parts of Northeast Massachusetts.

For Sunday, conditions are lining up favorably for isolated to scattered strong to severe thunderstorms across Southern New England for Sunday Afternoon and evening. The headlines depict the current thinking. Key factors for Sunday’s severe weather potential will be as follows:

1.) The position of the cold front/impulse in the atmosphere and the timing as it sweeps through the area. This is expected to be between 3-9 PM Sunday Afternoon and evening which should take advantage of the highest instability timeframe.
2.) Wind fields will be marginal but current models have brought up the wind levels slightly. Given that change and the level of instability and some other parameters pertaining to downdraft instability, the wind fields should be sufficient for isolated to scattered strong to severe thunderstorms.
3.) While the likely timeframe for severe weather is between 3-9 PM with the actual cold front and impulse that will swing through the area, the setup of a seabreeze front and differential heating in terrain may allow activity in some areas to start a bit early between 12-3 PM in isolated locations. There is also the possibility of an isolated strong to severe thunderstorm extending past 9 PM to as late as 11 PM as instability will hold on through mid to late evening before waning after 11 PM. Amateur Radio Field Day sites towards afternoon should keep an eye to the sky and monitor conditions though the greatest risk for severe weather will be at the end of the event where any field sites will be taking down their field setups.

SKYWARN Self-Activation will monitor conditions throughout Field Day weekend with Amateur Radio Call Up Nets brought up as required. Below are links to the NWS Boston/Norton Hazardous Weather Outlook, NWS Boston/Norton Enhanced Hazardous Weather Outlook, and SPC Day-1 Convective Outlook:

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. 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:

During setup and takedown of Amateur Radio Field Day sites and even while operating, be sure to drink plenty of fluids and eat accordingly. Also having a jacket or sweatshirt during evenings as conditions cool and rain gear for any showers and thunderstorms etc. may also be useful while operating this year’s Field Day.

Given the threat for thunderstorms in isolated to scattered locations over the course of Friday and the weekend, lightning is a threat to any and all Amateur Radio Field Day sites. Remember your lightning safety tips and details on lightning safety can be seen at the following link:
