Hello to all…

..Active Weather Pattern through Friday with additional severe weather potential Wednesday and people in Southern New England need to begin monitoring Tropical Storm Elsa for potential impacts of heavy rainfall along and northwest of the track, strong to damaging winds along and southeast of the track including the potential for severe weather and the possibility of minor coastal storm surge flooding..
..Starting with Wednesday, the Storm Prediction Center (SPC) has placed much of Southern New England in a Slight Risk of severe weather today as another potential round of Isolated to Scattered strong to severe thunderstorms are likely anytime between 1-9 PM EDT Wednesday across the region. Strong to damaging winds, hail, frequent lightning and heavy rainfall leading to urban and poor drainage flooding are the main threats..
..Impacts from Tropical Storm Elsa could be felt beginning late Thursday Night and especially Friday across much of Southern New England. Will briefly mention her potential impacts to the region in this message and provide more details in future coordination messages.
..SKYWARN Self-Activation will monitor severe weather potential for Wednesday and the impacts of Tropical Storm Elsa Thursday Night into Friday..
..Pictures and videos of storm damage, hail, and flooding can be sent as a reply to this message, via our WX1BOX Facebook and Twitter feeds and to our email address pics@nsradio.org..

Yesterday featured another fairly widespread severe weather event with pockets of tree and wire damage and power outages across Southern New England. The latest Local Storm Report giving the latest reports from this event can be seen here:

NWS Boston/Norton Local Storm Report – Tuesday 7/6/21 Severe Weather event:

Pictures and videos of storm damage, hail, and flooding can be sent as a reply to this message, via our WX1BOX Facebook and Twitter feeds and to our email address pics@nsradio.org.

Another round of isolated to scattered strong to severe thunderstorms are likely today across much of Southern New England. Intense heating and humidity will allow for high instability. Wind fields are similar to Tuesday in the region. Models show a cluster of storms ranging from impacts across much of interior Massachusetts north of the Mass Pike to a similar setup to yesterday where much of Massachusetts, Connecticut and parts of Rhode Island have a line of strong to severe thunderstorms sweep through the region. The key factors on how widespread the potential severe weather is for Wednesday is as follows:

1.) High instability levels compensating for marginally strong wind shear profiles.
2.) If wind shear profiles are a bit stronger than modeled, it would increase the coverage of strong to severe thunderstorms.
3.) A strong enough trigger to tap into the high instability and marginally strong wind fields in the atmosphere.

As we look ahead to the Thursday Night and Friday timeframe, we will have the potential for impacts of Tropical Storm Elsa in our region. Elsa has the potential to bring heavy rainfall along and northwest of the track and strong to damaging winds, minor coastal flooding and the potential for severe weather along and southeast of the track. The current Elsa track has Elsa slicing through Southern New England meaning portions of Southeast Massachusetts, Rhode Island and Cape Cod and the Islands could get into the stronger wind and severe weather part of the tropical system with much of the rest of Southern New England getting into the heavy rainfall side of the system. A track difference as little as 50 miles will affect outcomes across Southern New England. Now is the time to prepare for tropical storm like conditions particularly in Southeast New England with heavy rainfall and potential for pockets of river, stream and urban flooding in portions of interior Southern New England north and west of the storm center. Further details will be posted in future coordination messages.

SKYWARN Self-Activation will monitor severe weather potential for Wednesday and the impacts of Tropical Storm Elsa Thursday Night into Friday. Another coordination message more focused on Tropical Storm Elsa will be posted by 11 PM EDT Wednesday Evening or worse case 9 AM EDT Thursday Morning.

Hello to all…

..Isolated to Scattered Strong to Severe Thunderstorms are likely Tuesday Afternoon and Evening across Southern New England with strong to damaging winds, hail, frequent lightning and heavy rainfall with urban and poor drainage flooding are the primary threats. The Storm Prediction Center (SPC) has continued all of Southern New England in a Slight risk for severe weather with the timeframe between 1-8 PM Tuesday Afternoon and Evening..
..SKYWARN Self-Activation will monitor the severe weather potential for Tuesday Afternoon and Evening..

Heat and humidity will return to Southern New England Tuesday and with an impulse in the atmosphere, it will set the stage for isolated to scattered strong to severe thunderstorms during the Tuesday afternoon and evening hours. The headlines depict the current thinking with little change from last night. Key factors remain and include:

1.) Wind shear values will be marginally conducive for severe thunderstorms with damaging wind gusts. If that shear becomes stronger, it could potentially mean a greater more widespread severe weather risk and this will be monitored. Certain mid-level instability parameters are also marginally favorable for severe thunderstorm development.
2.) There is some cloud cover in the region and with the overnight thunderstorms being a bit more robust than modeled, it does create some uncertainty on whether the impulse in the atmosphere will break and capping to allow for strong to severe thunderstorm development. At this time, models still show the potential across much of Southern New England and despite cloud cover that is in the area, instability remains elevated over the region and should increase with breaks in the clouds noted on satellite imagery.
3.) Timing of strong to severe thunderstorm development in the area as some models show earlier timing but near the time of peak heating and other models show the development towards late afternoon and evening. This timing would be favorable but if showers and thunderstorms build in earlier towards mid to late morning or produce more cloud cover, this could limit the severe weather potential. At this time, models are giving a favorable timeframe for strong to severe thunderstorm development.

It is noted that we are also in a marginal risk for severe weather in portions of Southern New England for Wednesday. This will be discussed as needed in a future coordination message posted by 11 PM Tuesday Evening.

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

Hello to all…

..After the most widespread severe weather event so far in the 2021 Severe Weather Season, a more marginal risk for Isolated to Scattered Strong to Severe Thunderstorms exists this Thursday Afternoon and Evening between 1-9 PM across Central and Eastern Connecticut, Rhode Island and Southeast Massachusetts. Heavy downpours and urban and poor drainage flooding is the primary threat with a secondary threat for strong to damaging winds and hail..
..The Storm Prediction Center (SPC) has placed Central and Eastern Connecticut, Rhode Island and Southeast Massachusetts in a marginal risk for severe weather for this Thursday Afternoon and Evening..
..SKYWARN Self-Activation will monitor the severe weather and flood potential for Thursday Afternoon and Evening..
..Post storm wind damage, lightning damage, hail and flooding reports, pictures and videos from the Wednesday 6/30/21 and today’s potential severe weather/flood event can be sent via our WX1BOX Facebook and Twitter feeds and to the email address pics@nsradio.org. Credit will be given to the spotter for providing the pictures, videos, reports..

Wednesday 6/30/21 brought the most widespread severe weather event so far in the 2021 Severe Thunderstorm/Severe Weather Season in our coverage area. The latest Local Storm Report on Wednesday 6/30/21 severe weather event can be seen here:

NWS Boston/Norton Local Storm Report:
https://kamala.cod.edu/offs/KBOX/2107010134.nwus51.html

As stated in the headlines, post storm wind damage, lightning damage, hail and flooding reports, pictures and videos from the Wednesday 6/30/21 and today’s potential severe weather/flood event can be sent via our WX1BOX Facebook and Twitter feeds and to the email address pics@nsradio.org. Credit will be given to the spotter for providing the pictures, videos, reports.

A more limited potential for isolated to scattered strong to severe thunderstorms are possible across Central and Eastern Connecticut, Rhode Island and South-Central and Southeast Massachusetts this Thursday Afternoon and Evening from 1-9 PM EDT. The headlines depict the current thinking. Key factors include:

1.) Amount of sunshine to allow for heating and destabilization. Cloud cover is not as extensive as previously thought with some sizeable breaks in the clouds in the marginal risk area. This is expected to allow for increased instability and part of the reason for the marginal risk upgrade in Central and Eastern Connecticut, Rhode Island, and South-Central and Southeast Massachusetts.
2.) Wind shear in the atmosphere will be strong so with the increased instability due to more breaks of sunshine, a few isolated to scattered strong to severe thunderstorms could cause strong to damaging winds and hail in the SPC marginal risk area.

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

Hello to all…

..Isolated to Scattered Severe thunderstorms caused pockets of wind damage and flooding in portions of Western Massachusetts, Northern Connecticut, Northwest Rhode Island and in the Metro Boston/Brookline/Newton area Tuesday. Any additional damage reports, photos and videos from the Tuesday 6/29/21 severe weather event can be sent as a reply to this message, via our WX1BOX Facebook/Twitter feeds or for photos and videos, they can be sent to the email address pics@nsradio.org..
..Scattered to numerous strong to severe thunderstorms are expected Wednesday afternoon and evening across much of Southern New England between 2-10 PM. The Storm Prediction Center (SPC) has continued Extreme Northern Connecticut, Northwest Rhode Island and Western, Central and Northeast Massachusetts including the metro Boston area to an Enhanced risk for severe weather while the rest of Southern New England north and west of the Cape Cod Canal is in a slight risk for severe weather with a marginal risk for severe weather for Cape Cod and the Islands. Damaging Winds, hail, frequent lightning and heavy rainfall with urban to poor drainage flooding to possibly flash flooding are the main threats..
..A Heat Advisory remains in effect through 7 PM Wednesday Evening for all of the NWS Boston/Norton coverage area except for Cape Cod and the Islands for heat indices between 97-103 degrees. Anyone exerting themselves outside should take frequent breaks, drink plenty of liquids and seek air conditioned areas wherever possible to avoid heat related illnesses..
..SKYWARN Self-Activation will monitor the severe weather potential Wednesday Afternoon and Evening..

Intense heat and humidity continues across much of Southern New England today and will continue through at least Wednesday. Heat Advisories are posted for much of Southern New England away from Cape Cod and the Islands. Links to the apparent maximum temperatures factoring in humidity and dewpoints can be seen here:

NWS Boston/Norton Apparent Maximum Temperatures:
https://wx1box.org/wp-content/uploads/2021/06/Heat-Indices-Wednesday.png

Tuesday also featured a bit more coverage in strong to severe thunderstorms across the area particularly in Western and Central Massachusetts, Northern Connecticut and Northwest Rhode Island as well as the Brookline/Boston/Newton area. Any additional damage reports, photos and videos from the Tuesday 6/29/21 severe weather event can be sent as a reply to this message, via our WX1BOX Facebook/Twitter feeds or for photos and videos, they can be sent to the email address pics@nsradio.org. The Tuesday Evening NWS Boston/Norton Local Storm Report can be seen below:

https://kamala.cod.edu/offs/KBOX/2106300125.nwus51.html

Severe weather potential continues to fairly high for Wednesday Afternoon and Evening and SPC has continued the enhanced risk in parts of our coverage area as indicated in the headlines. A cold front will be approaching the region and with the intense heat and humidity in place and increasing winds aloft, it will set the stage for a greater risk of strong to severe thunderstorm development along with a greater coverage of strong to severe thunderstorms across Southern New England. Key items for Wednesday will be how quickly the cold front gets into or close enough to the region to provide a trigger for thunderstorm development and the overlap of the stronger winds aloft with high instability over the region from intense heating and humidity through the day. No cloud cover remains over the region so intense heating will continue through the day. The main threat appears to be clusters or lines of strong to severe thunderstorms with damaging winds, hail, frequent lightning and heavy rainfall leading to urban and poor drainage flooding to flash flooding in the area.

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

Hello to all…

..Intense heat and humidity with a second heat wave ongoing for much of Southern New England away from Cape Cod and the Islands through at least Wednesday of this week. A few isolated strong to possibly severe thunderstorms are possible today in parts of Western and Central Massachusetts, Northern Connecticut and Northern Rhode Island this Tuesday Afternoon and Evening though the best coverage of strong to severe thunderstorms are likely to be north and west of our area for Tuesday..
..For Wednesday, a more significant potential for isolated to scattered strong to severe thunderstorms is expected with an approaching cold front and the Storm Prediction Center (SPC) has placed the area from Boston to Providence north and west in a slight risk for severe weather with the rest of Southern New England in a marginal risk for severe weather. Strong to damaging winds, hail, frequent lightning and heavy downpours are the main threats..
..A Heat Advisory is now in effect through 7 PM Wednesday Evening for all of the NWS Boston/Norton coverage area except for Cape Cod and the Islands for heat indices between 97-103 degrees. Anyone exerting themselves outside should take frequent breaks, drink plenty of liquids and seek air conditioned areas wherever possible to avoid heat related illnesses..
..SKYWARN Self-Activation will monitor any strong to severe thunderstorm potential that develops on Tuesday Afternoon and Evening and especially Wednesday Afternoon and evening..

Intense heat and humidity continues across much of Southern New England today and will continue through at least Wednesday.

https://wx1box.org/wp-content/uploads/2021/06/Heat-Indices-Wednesday.png

Severe weather potential will be on the increase particularly on Wednesday but there is some potential for an isolated strong to severe thunderstorm or two this Tuesday Afternoon and Evening as there will be some marginal triggers to the unstable atmosphere that could allow for a few isolated strong to severe thunderstorms with the greatest risk in Western Massachusetts, Northern Connecticut and Northwest Rhode Island. The greater potential is noted to be north and west of our coverage area but some models do produce a few pop-up thunderstorms and the potential for an isolated strong to severe thunderstorm or two.

On Wednesday, a cold front will be approaching the region and with the intense heat and humidity in place and increasing winds aloft, it will set the stage for a greater risk of strong to severe thunderstorm development along with a greater coverage of strong to severe thunderstorms across Southern New England. Key items for Wednesday will be how quickly the cold front gets into or close enough to the region to provide a trigger for thunderstorm development and the overlap of the stronger winds aloft with high instability over the region from intense heating and humidity through the day.

Hello to all…

..Intense Heat and humidity with the start of a second heat wave for much of Southern New England away from coastal areas expected for much of this week. There will also be the potential for thunderstorms and a few isolated strong to severe thunderstorms over the next few days in interior locations starting Monday Afternoon and Evening. The primary threat from these storms will be frequent lightning and heavy downpours but a secondary threat will be strong to damaging winds and hail..
..A Heat Advisory is now in effect through 7 PM Tuesday Evening for Northern Connecticut, Eastern Hampden, Eastern Hampshire, Eastern Franklin Counties, Worcester, Middlesex, Essex, Suffolk, Norfolk, North-central Bristol, North-central Plymouth Counties of Massachusetts, Providence and Kent Counties of Rhode Island for heat indices of 98 to 104 degrees except Kent County RI here heat indices are expected to be 95-99 degrees. Some portions of the heat advisory area could be upgraded to Excessive Heat Warnings for heat indices greater than 105 degrees..
..SKYWARN Self-Activation will monitor any strong to severe thunderstorm potential that develops on Monday Afternoon and Evening. Another coordination message will be posted by 1 PM Monday Afternoon.

Hello to all..

..The following is the second 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 18 years for Amateur Radio Operators involved with Field Day and the NWS Boston/Norton SKYWARN Program..
..2021 Field Day weekend will now be dry, warm and humid with shower and thunderstorm risks pushed out beyond this weekend due to the positioning of the ride and the heat in the region. The potential for severe weather or any lightning threat for Sunday has been removed..
..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 lingering COVID-19 concerns, Amateur Radio Field Day across Southern New England will be a bit different with somewhat less Field Day sites than normal in the region but more sites than 2020. Those that are up and running may have some level of COVID-19 protocols in place. There will be some 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 as needed..

Here are some links to information on these Amateur Radio Field Day Sites from across the region understanding there could be some COVID-19 protocols in place depending on the field day sites:

The weekend is now expected to be warm, humid an dry throughout the entire period with thunderstorm chances removed from the Sunday timeframe. For Saturday, temperature will be in the 80s with lows in the 60s and on Sunday, temperatures will be in the Upper 80s to lower 90s away from the coast with heat indices in the mid to upper 90s. This may prompt heat advisories for Sunday as the start of a several day heat wave could occur as early as Sunday in parts of the region. Due to the positioning of high pressure in the area, thunderstorm chances were removed from the forecast meaning that is not a threat for this weekend. Coastal areas will be cooler with temperatures in the Upper 70s to lower 80s for highs and 60s for lows. There could be low clouds and fog each morning on the coast that will burn off later in the day. It will be important for Amateur Radio Field Day sites operating outside to drink plenty of liquids and to stay cool as the temperatures this weekend will be a precursor to a potential heat wave to start the new work week.

Below are links to the NWS Boston/Norton Hazardous Weather Outlook, NWS Boston/Norton Enhanced Hazardous Weather Outlook and a graphic on max apparent temperatures for Sunday which accounts for heat and humidity and what conditions will feel like in the region:

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:

This will be the last Amateur Radio Field Day Coordination Message since the threat for thunderstorms is reduced and the main concern is heat and humidity particularly on the Sunday of Field Day. A shortened coordination message may be posted if a significant change to the situation occurs and time allows for an update.

Hello to all..

..The following is the first 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 18 years for Amateur Radio Operators involved with Field Day and the NWS Boston/Norton SKYWARN Program..
..2021 Field Day weekend will mostly be dry, warm and humid but has potential shower and thunderstorm risks in isolated to scattered locations particularly on Sunday. The potential for severe weather on Sunday is low but frequent lightning is a threat near any scattered thunderstorms that can develop..
..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 lingering COVID-19 concerns, Amateur Radio Field Day across Southern New England will be a bit different with somewhat less Field Day sites than normal in the region but more sites than 2020. Those that are up and running may have some level of COVID-19 protocols in place. There will be some 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 as needed..

Here are some links to information on these Amateur Radio Field Day Sites from across the region understanding there could be some COVID-19 protocols in place depending on the field day sites:

While most of the weekend will be dry, there will be scattered showers and thunderstorm chances particularly on Sunday. Warm and humid conditions will prevail in the region with highs in the 80s with a few locations reaching around 90 degrees possibly on Sunday and lows in the 60s to lower 70s. It will be important for Amateur Radio Field Day sites operating outside to drink plenty of liquids and to stay cool as the temperatures this weekend will be a precursor to a potential heat wave to start the new work week. Coordination messages will be sent throughout the weekend to monitor the potential for any thunderstorms on the Sunday of Amateur Radio Field Day weekend.
