Hello to all…

..A second cold front will approach Southern New England Thursday Afternoon and Evening setting the stage for thunderstorms with frequent lightning and heavy rainfall leading to localized urban and poor drainage flooding as the main threats but can’t rule out Isolated Strong to Severe Thunderstorms with strong to damaging winds and hail as well with the main threat area across central and eastern parts of Southern New England. Timeframe is in the 2-9 PM ET Thursday Afternoon and Evening timeframe..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible to likely for Thursday Afternoon and Evening. Pictures and videos of storm damage, hail, and flooding can be sent as a reply to this email, via our WX1BOX Facebook, X and Bluesky feeds or to the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated..

Wednesday 8/13/25 brought a round of isolated severe thunderstorms and localized flooding to the region. The complete log of reports can be seen here:
https://wx1box.org/wp-content/uploads/2025/08/reports_8_13_25.pdf

Heat and humidity though a bit cooler than Wednesday is expected today followed by a second cold front with the main threat being thunderstorms with heavy rainfall and localized flooding The headlines depict the current thinking. Key factors include:

1.) The timing and strength of the cold front into the area near the time of peak heating to take advantage of instability despite weak wind shear profiles.
2.) Cloud cover and amount of clearing to determine the level of instability. More clearing with higher instability increases the threat for thunderstorms with localized flooding and the isolated strong to severe thunderstorm risk.
3.) As always with severe/non-severe thunderstorm events, not all locations will receive a severe/non-severe thunderstorm. They will be isolated to scattered with pockets of wind damage, hail and urban/poor drainage flooding in those isolated to scattered locations.

SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible to likely for Thursday Afternoon and Evening.

Hello to all…

The 2025 Northeast HamXposition and ARRL New England Division Convention will be held from Thursday Evening 8/21/25-Sunday 8/24/25. There will be many interesting forums at this year’s convention. For complete information on this Amateur Radio Convention, please see the following link:
https://hamxposition.org/

The Convention is honored and privileged that Matt and Danielle Noyes will return and provide an update on their digital weather venture, 1Degree Outside. They will be presenting about their latest updates and ventures for their new company and have entered into a partnership with the WX1BOX Amateur Radio SKYWARN team on SKYWARN surface reporting during severe weather. They will discuss the new partnership and the vital role Amateur Radio & non-Amateur Radio SKYWARN Spotters play with surface reporting during severe weather events and how they incorporate the data into their operations.

We will also have a SKYWARN/ARES/RACES table at the Convention as we have had going back to the late 1990s. In addition, there will be several SKYWARN and weather related topics including SKYWARN Training and Advanced Topics in SKYWARN presentation with new material added for this year which will be taught by KD1CY-Rob Macedo, Eastern Mass ARES SEC & SKYWARN Coordinator.

A list of the key SKYWARN and weather related presentations for Northeast HamXposition are listed below:

Friday 8/22/25:
100 PM: SKYWARN Spotter training by KD1CY-Rob Macedo

Saturday 8/23/25:
200 PM: Advanced Topics in SKYWARN – Doppler Radar Fundamentals & How You Can Help with Severe Weather Reporting Situational Awareness by KD1CY-Rob Macedo
300 PM: 1DegreeOutside: Their Digital-First Weather Approach One Year Later & Vital Partnership with the WX1BOX Amateur Radio SKYWARN Team by Matt and Danielle Noyes
There are many other topics related to ARES and Emergency Communications at the convention. The full schedule of presentations can be seen here:
https://registration.hamxposition.org/Schedule/

The Convention also features a full Amateur Radio Flea Market and Amateur Radio vendors. For those that maybe interested in getting their Amateur Radio license, the convention has a “Tech in a Day” class on Saturday 8/23/25 and several Volunteer Examiner (VE) test sessions as listed on the schedule.

We hope many from the Amateur Radio community and even those outside of the Amateur Radio community can attend and see the SKYWARN/Weather related presentations and for those that might be interested in getting their Amateur Radio license, use the convention as an opportunity to get licensed by preparing ahead of time or take advantage of the Tech-In-A-Day licensing class offered. Thanks to all for their support!

Hello to all…

..A cold front will approach Southern New England Wednesday Afternoon and Evening setting the stage for Isolated to Scattered Strong to Severe Thunderstorms with strong to damaging winds, hail, frequent lightning and heavy rainfall leading to urban and poor drainage flooding as the main threats. The threat maybe more isolated than what was being seen in models yesterday but marginal risk for severe weather has been maintained for the region..
..The Storm Prediction Center (SPC) has placed all of Southern New England in a marginal risk for severe weather so this means an expansion through Southeast Coastal New England. Timeframe for severe weather is between 2-10 PM ET Wednesday..
..A Heat Advisory is in effect through 8 PM Wednesday for all of Southern New England except for the east slopes of the Berkshires, Cape Cod and the Islands with heat indices up to 101 degrees. Use caution in working outdoors, take frequent breaks, spend time in cooler areas and stay hydrated..
..Heavy rainfall including from thunderstorms is possible Thursday into early Friday potentially resulting in flooding issues as the cold front stalls over Southern New England before moving south of the region Friday bringing pleasant weekend weather. Further details on this heavy rainfall for Thursday into early Friday will follow after the severe weather potential for Wednesday has passed..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible to likely for Wednesday Afternoon and Evening. SKYWARN Activation with Amateur Radio Call-Up Nets are also possible Thursday into Friday AM for heavy rainfall/flood potential. Pictures and videos of storm damage, hail, and flooding can be sent as a reply to this email, via our WX1BOX Facebook, X and Bluesky feeds or to the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated..

One more day of heat and humidity before a cold front moves into the area Wednesday Afternoon and Evening and stall over Southern New England Friday then shifts south of the area during the day Friday. The headlines depict the current thinking. Key factors include:

1.) The timing of the cold front into the area near the time of peak heating to take advantage of strong wind shear profiles.
2.) Frontal forcing, instability and wind shear to offset some unfavorable severe weather parameters.
3.) Mid-level drying during the day Wednesday if that occurs and whether moisture returns in the mid-levels during the time of peak heating.
4.) Cooling temperatures aloft and how this could offset unfavorable severe weather parameters particularly the mid-level drying
5.) As always with severe/non-severe thunderstorm events, not all locations will receive a severe/non-severe thunderstorm. They will be isolated to scattered with pockets of wind damage, hail and urban/poor drainage flooding in those isolated to scattered locations.

Heavy rainfall including from thunderstorms is possible Thursday into early Friday potentially resulting in flooding issues as the cold front stalls over Southern New England before moving south of the region Friday bringing pleasant weekend weather.

Hello to all…

..One more day of heat and humidity before a cold front brings slightly cooler conditions for Saturday. A cold front will bring about some relief but will set the stage for Isolated to Scattered Strong to Severe Thunderstorms with strong to damaging winds, hail, frequent lightning and heavy downpours leading to urban and poor drainage flooding as the main threats..
..The Storm Prediction Center (SPC) has expanded the slight risk area to cover much of Massachusetts, Connecticut and Rhode Island away from the Southeast Coast of Massachusetts and Rhode Island where there remains a marginal risk for severe weather. Timeframe for severe weather is between 1-10 PM ET Friday..
..A Heat Advisory remains in effect through 8 PM Friday for all of Southern New England except for the east slopes of the Berkshires, South Coastal Massachusetts and Rhode Island including Cape Cod and the Islands with heat indices up to 103 degrees. Use caution in working outdoors, take frequent breaks, spend time in cooler areas and stay hydrated..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible to likely for Friday Afternoon and Evening. Pictures and videos of storm damage, hail, and flooding can be sent as a reply to this email, via our WX1BOX Facebook, X and Bluesky feeds or to the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated..

One more day of heat and humidity before a cold front brings some relief to heat though it will remain humid this weekend. The headlines depict the current thinking. Key factors remain:

1.) The timing of the cold front which looks favorable for severe weather development currently.
2.) Frontal forcing, instability and wind share to offset some unfavorable severe weather parameters. This will determine how much coverage of strong to severe thunderstorms over the area.
3.) As always with severe/non-severe thunderstorm events, not all locations will receive a severe/non-severe thunderstorm. They will be isolated to scattered with pockets of wind damage, hail and urban/poor drainage flooding in those isolated to scattered locations.

Hello to all…

..The morning round of potential thunderstorms for Southeast New England has tracked further south with only showers and an isolated thunderstorm expected over Cape Cod and the Islands this morning. There will then be a period of dry weather followed by the potential for isolated to scattered strong to severe thunderstorms Sunday Afternoon and Evening between 2-10 PM with strong to damaging winds, hail, frequent lightning and heavy downpours leading to urban and poor drainage flooding as the main threats..
..The Storm Prediction Center has maintained Southern New England in a Slight Risk for Severe Weather except for Cape Cod and the Islands which is in a marginal risk for severe weather for Sunday Afternoon and Evening..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are likely Sunday Afternoon and Evening for much of the area where isolated to scattered strong to severe thunderstorms occur. Pictures and videos of storm damage, hail, and flooding can be sent as a reply to this email, via our WX1BOX Facebook, X and Bluesky feeds or to the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated..

Sunday has potential to be a fairly active day in Southern New England with a brief period of heat and humidity. Morning thunderstorm activity with localized flood potential is tracking south and east of Southeast New England though showers and an isolated thunderstorm could occur through midday today particularly over the islands and possibly Cape Cod. As this area departs, there will be a period of dry weather with heating and destabilization that sets the stage for isolated to scattered severe thunderstorm development. The headlines depict the current thinking. Key factors include:

1.) The track of morning thunderstorms Sunday Morning with flood potential for Southeast New England is further south than modeled yesterday morning so while there will be some showers and an isolated thunderstorm, this should move out by midday. Satellite pictures show breaks in cloud cover especially across Northern Massachusetts and further breaks back into New York State that should allow for heating and destabilization for much of the region which will be monitored closely.
2.) Timing of the cold front to take advantage of favorable instability and shear profiles to offset a few negative parameters on severe weather potential. Current timing would be prime for development of strong to severe thunderstorms Sunday Afternoon and Evening if expected heating and destabilization occurs.
3.) As always with severe/non-severe thunderstorm events, not all locations will receive a severe/non-severe thunderstorm. They will be isolated to scattered with pockets of wind damage, hail and urban/poor drainage flooding in those isolated to scattered locations.

SKYWARN Self-Activation with Amateur Radio Call-Up Nets are likely Sunday Afternoon and Evening for much of the area where isolated to scattered strong to severe thunderstorms occur.

Hello to all…

..A round of thunderstorms Sunday Morning between 6-11 AM may cause localized flooding in Southeast New England unless these thunderstorms track south of this area Sunday Morning. There will then be a period of dry weather followed by the potential for isolated to scattered strong to severe thunderstorms Sunday Afternoon and Evening between 2-8 PM with strong to damaging winds, hail, frequent lightning and heavy downpours leading to urban and poor drainage flooding as the main threats..
..The Storm Prediction Center has placed much of Southern New England in a Slight Risk for Severe Weather except for Cape Cod and the Islands which is in a marginal risk for severe weather for Sunday..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible to likely Sunday Morning in Southeast New England and again Sunday Afternoon and Evening for much of the area. Pictures and videos of storm damage, hail, and flooding can be sent as a reply to this email, via our WX1BOX Facebook, X and Bluesky feeds or to the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated..

Sunday has potential to be a fairly active day in Southern New England with a brief period of heat and humidity as a round of thunderstorms with heavy rainfall and localized flood potential either affects Southeast New England or stays south of this area in the morning followed by a cold front with severe weather potential Sunday Afternoon and Evening. The headlines depict the current thinking. Key factors include:

1.) The track of morning thunderstorms Sunday Morning with flood potential for Southeast New England and whether that goes over the area or tracks south of the south coast.
2.) Expected clearing to allow for destabilization in the wake of any Sunday morning thunderstorm activity.
3.) Timing of the cold front to take advantage of favorable instability and shear profiles to offset a few negative parameters on severe weather potential. Current timing would be prime for development of strong to severe thunderstorms Sunday Afternoon and Evening if expected heating and destabilization occurs.

SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible to likely Sunday Morning in Southeast New England and again Sunday Afternoon and Evening for much of the area. Pictures and videos of storm damage, hail, and flooding can be sent as a reply to this email, via our WX1BOX Facebook, X and Bluesky feeds or to the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated. The next coordination message will be posted by either 11 PM Saturday Evening or 11 AM Sunday Morning as time permits.

Hello to all…

..Isolated to Scattered Strong to Severe Thunderstorms are possible across Western Massachusetts and much of Connecticut later this Thursday Afternoon and Evening after 4 PM as a cold front will bring the end to the heat and humidity in Southern New England. Strong to damaging winds, hail, frequent lightning, and heavy rainfall with urban and poor drainage flooding are the main threats but can’t rule out an isolated tornado if some unfavorable convective parameters for the region are overcome..
..The Storm Prediction Center (SPC) has placed Western and Central Massachusetts and much of Connecticut in a marginal risk for severe weather for Thursday Afternoon and Evening with a slight risk up across portions of Western Maine, Northern New Hampshire and Northern Vermont..
..A Heat Advisory remains in effect through 7 PM Thursday Evening for much of Southern New England except for the East slopes of the Berkshires and Cape Cod and the Islands for heat indices up to 100 degrees. Use caution in the heat by hydrating and taking freaking breaks in air conditioning if exerting yourself outdoors today..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible to likely this Thursday Afternoon and Evening. Pictures and videos of storm damage, hail, and flooding can be sent as a reply to this email, via our WX1BOX Facebook, X and Bluesky feeds or to the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated..
Our final day of heat and humidity occurs today as a cold front will bring cooler and less humid conditions Friday into Saturday. It will set the stage for isolated to scattered strong to severe thunderstorms ahead of the cold front Thursday Afternoon and Evening. The headlines depict the current thinking. Key factors include:

1.) There is favorable shear and satellite imagery shows sufficient clearing for destabilization in the region for later today. Timing of the cold front and forcing with this front seems to be best in Northern New England but we will need to monitor if there is enough forcing to take advantage of favorable shear and instability parameters in the marginal risk area.
2.) There are some limiting severe weather parameters but if they are overcome or better than expected, that could increase the risk for severe weather potential.
3.) Coverage of severe thunderstorms will most likely be isolated to scattered but if items 1 and 2 line up accordingly, it could allow for the severe thunderstorms to be a bit more widespread.

Pictures and videos of storm damage, hail, and flooding can be sent as a reply to this email, via our WX1BOX Facebook, X and Bluesky feeds or to the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated. This will be the only coordination message unless a significant change to the situation occurs and time allows for an update as we shift into operations mode.
