Severe Weather Coordination Message #2 – Tuesday PM & Evening 7/21/26 & Wednesday PM & Evening 7/22/26 Severe Weather & Flash Flood Potential

Hello to all…

..A warm front followed by a strong pre-frontal trough and then a cold front will approach Southern New England late Tuesday Morning through Wednesday evening setting the stage for potentially two or perhaps three rounds of isolated to scattered strong to severe thunderstorms one late Tuesday AM into mid-Tuesday Afternoon which is the most conditional and weaker potential, a second round Tuesday Evening through the overnight hours into early Wednesday Morning with a third round of severe weather potential Wednesday PM and Evening. Much of Southern New England has severe weather potential but the greatest risk is over Western and Central Massachusetts, Connecticut, Rhode Island and into South Coastal Massachusetts Tuesday PM through early Wednesday AM while all of New England has a marginal risk Wednesday PM and Evening..

..The Storm Prediction Center (SPC) has a Marginal risk for severe weather Tuesday Afternoon through early Wednesday AM across Western and Central Massachusetts, Connecticut and Rhode Island. Threat potential timeframe is between 4 PM Tuesday through 4 AM Wednesday though we will need to monitor activity along the warm front late Tuesday AM into mid-afternoon Tuesday for a more conditional lower risk threat of severe weather. The Storm Prediction Center (SPC) also has all of Southern New England in a marginal risk for severe weather for Wednesday Afternoon and Evening. Strong to damaging winds, hail, frequent lightning and heavy downpours leading to urban and poor drainage flooding are the primary risks but even an isolated tornado cannot be ruled out..

..In addition, a High Surf Advisory is in effect from 6 AM Wednesday to 8 PM Thursday for Cape Cod and the Islands, Washington, Newport Counties of Rhode Island, Southern Plymouth and Southern Bristol Counties of Massachusetts for dangerous surf and rip current conditions..

..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible late Tuesday Morning through early Wednesday AM and again Wednesday Afternoon and Evening based on the severe weather and flash flood potential. Pictures and videos of wind damage, hail, flooding etc. can be sent as a reply to this email, via our Facebook/X/Bluesky feeds or the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated..

Active couple days for severe weather and flash flood potential. The headlines depict the current thinking. Key factors include:

Tuesday Key Factors:
1.) A warm front is pushing through the region and while this warm front is less likely to produce severe weather, there is one severe thunderstorm warning in Southeast NY as of 1030 AM and there is an isolated risk for a strong or severe thunderstorm with the warm front as it moves through the area and will bear watching.

2.) Clearing to allow for destabilization ahead of the pre-frontal trough to allow for instability for severe weather potential into later Tuesday Evening. Shear profiles are sufficiently strong enough to produce severe weather.

3.) Strong wind shear being able to compensate for limited instability and timing of the pre-frontal trough past peak heating into the evening and overnight hours.

Wednesday Key Factors:
1.) Wind shear will remain sufficiently strong for severe weather but instability is in question depending on clearing to allow for destabilization.

2.) Wind shear and its ability to compensate for limited instability if that occurs.

3.) Timing of the cold front through New England which is currently expected to be favorable in the mid to late afternoon and early evening.

SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible late Tuesday Morning through early Wednesday AM and again Wednesday Afternoon and Evening based on the severe weather and flash flood potential.

Severe Weather Coordination Message #2 – Saturday PM & Evening 7/18/26 Severe Weather & Flash Flood Potential

Hello to all…

..A strong cold front will approach Southern New England Saturday Afternoon and evening setting the stage for potentially two rounds of isolated to scattered strong to severe thunderstorms one Saturday Early to Mid-Afternoon and the other Saturday late Afternoon & Evening with the more dominant severe weather potential late this afternoon and evening. Much of Southern New England has severe weather potential but the greatest risk is over Western and Central Massachusetts, Connecticut, Rhode Island and into South Coastal Massachusetts..

..The Storm Prediction Center (SPC) has Western and Central Massachusetts and all of Connecticut and Rhode Island in a slight risk for severe weather Saturday Afternoon and Evening and the rest of Southern New England along and north and west of the Cape Cod Canal in a marginal risk for severe weather. Threat potential timeframe is between 12 PM-12 AM Saturday though the highest risk in this timeframe maybe from around 3 PM-12 AM. Strong to damaging winds, hail, frequent lightning and heavy downpours leading to urban and poor drainage flooding are the primary risks but even an isolated tornado cannot be ruled out particularly in the slight risk for severe weather area..

..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible Saturday Afternoon and Evening based on the severe weather and flash potential. Pictures and videos of wind damage, hail, flooding etc. can be sent as a reply to this email, via our Facebook/X/Bluesky feeds or the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated..

The headlines depict the current thinking on severe weather potential for this Saturday Afternoon and Evening. Key factors include:

1.) Strong wind shear profiles are present but the degree of instability is in question between cloud cover and smoke. The level of instability or to the degree that strong wind shear can compensate limited instability will determine how significant and widespread severe weather can be in the area.

2.) Timing of the cold front to maximize instability that is present. The timing on some models has sped up a bit which is why the Slight risk has expanded eastward into more areas of Southern New England.

3.) A smoke plume may move through Southern New England which could limit instability. If its very thick like it was on Wednesday across all of Southern New England or like it was Thursday in Connecticut, it could limit severe weather potential but if its thin or moves through quickly like other parts of Southern New England on Thursday, it will be a non-factor.

Severe Weather Coordination Message #1 – Friday PM/Evening 7/10/26 Severe Weather Potential

Hello to all…

..While most areas may remain dry and are unlikely to see a strong or severe thunderstorm, an isolated strong to severe thunderstorm cannot be ruled out across Southern New England Friday Afternoon and Evening. The greatest potential may line up along and south of the Mass Pike. The Storm Prediction Center (SPC) has the region in a general risk for thunderstorms which means most to perhaps all thunderstorms will be “garden variety” with heavy rainfall, potentially causing brief urban and poor drainage flooding and frequent lightning but we can’t rule out an isolated strong or severe thunderstorm with strong to damaging winds and hail in addition to heavy rainfall and frequent lightning. The timing appears to be from roughly 1-9 PM this Friday PM and Evening..

..SKYWARN Self-Activation with Amateur Radio-Call Up Nets will monitor any severe weather potential this Friday PM and Evening. Pictures and videos of wind damage, hail, flooding etc. can be sent as a reply to this email, via our Facebook/X/Bluesky feeds or the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated. This will be the only coordination message as we shift into monitoring/operations mode. Below is the NWS Boston/Norton Area Forecast Discussion and Enhanced Hazardous Weather Outlook..

Storm Coordination Message #2 – Monday AM 7/6/26-Tuesday PM 7/7/26 Heavy Rainfall/Strong Wind Gust Potential

Hello to all…

..Storm system is expected to bring beneficial rainfall but the rainfall in some areas may come too fast or too heavy despite dry conditions and result in urban and poor drainage street flooding to potentially small river and stream flooding. Some strong wind gusts to around 40 MPH with isolated higher gusts are also possible at the coast which may cause isolated pockets of tree and wire damage and isolated power outages..
..A Flood Watch is now in effect through Tuesday PM for Connecticut, Rhode Island and Expanded to include all of Bristol, Plymouth and Barnstable Counties of Southeast Massachusetts for a widespread 1-3″ of rainfall but bands within the flood watch area could receive 4-6″+ of rainfall with isolated higher amounts inside of 6 hours. Those heavier bands of rainfall could result in urban, poor drainage flooding to flash flooding and the potential for small river and stream flooding. Areas outside of the flood watch should monitor as this rain area could shift a bit north, remain where it is or shift south in future updates..
..SKYWARN Self-Activation with Amateur Radio Call-Up nets are possible if a Flash Flood Warning is issued for rain gauge totals 1″ or more, any flooding issues, measured wind gusts 40 MPH or greater and any wind damage reports. Pictures and videos of wind damage, hail, flooding etc. can be sent as a reply to this email, via our Facebook/X/Bluesky feeds or 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 Monday Evening or 9 AM Tuesday Morning unless operations mode for flooding issues has already commenced.

Post Severe Weather Coordination Message #2 – Saturday 7/4/26 Significant Severe Weather Event in Connecticut

Hello to all…

..This is an updated message on the significant severe weather struck Connecticut from portions of Litchfield County Connecticut to Southern Hartford Connecticut through Southern Connecticut into extreme Southwest Rhode Island Saturday Evening July 4th 2026. Nearly 100,000 customers were without power in Connecticut at the height of the severe weather with approximately 42,000 without power at the time of this message Sunday Evening. In addition, hail up to 3″ in diameter in portions of Bristol, Terryville and Plainville, CT caused cracked and smashed windshields and home windows. Additional isolated severe thunderstorms occurred in Northeast Massachusetts..
.. Pictures and videos of wind damage, hail, flooding etc. can be sent as a reply to this email, via our Facebook/X/Bluesky feeds or the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated. Understanding hardest hit areas may not get their power back for several days, getting the late reports, pics and videos even several days later is helpful for post storm analysis..
..A Facebook Photo Album has been created with damage photos and hail from this severe weather event. We have also provided an updated WX1BOX Amateur Radio Report log of reports received. This post severe weather message will likely be updated one more time but this may not occur until the weekend of 7/11-7/12 depending on new data received and how the potential heavy rainfall/flood potential for Monday 7/6/26-Tuesday 7/7/26 unfolds for the region. Below is the WX1BOX Facebook Photo Album of photos with credit given to the spotter on each photo and the WX1BOX Amateur Radio Log from this significant severe weather event..

Heat & Severe Weather Coordination Message #7 – Saturday 7/4/26 US Independence Day Heat & Severe Weather Potential

Hello to all…

..Happy Independence Day to all Amateur Radio and non-Amateur Radio SKYWARN Spotters and we appreciate everyone’s support of the SKYWARN program and celebrate America’s 250th Birthday. We hope everyone enjoys the holiday and also keeps a watchful eye on today’s severe weather potential..
..Friday continued extreme heat over Southern New England but less thunderstorm activity than prior days with strong thunderstorms doing minor wind damage in parts of Berkshire County Mass late Friday Night before weakening moving into our coverage area. The WX1BOX Amateur Radio Report log for Thursday Evening 7/2/26 and for the 7/1/26-7/2/26 and 6/30/26 severe weather events remain in this update..
..Intense Heat Wave winds down today, Saturday July 4th 2026, with very slightly cooler conditions which has meant the Extreme Heat Warning has been downgraded to a Heat Advisory but nonetheless caution is advised to stay cool due to several prior days of extreme heat and hot and humid conditions will continue today..
..A Heat Advisory is now in effect through 8 PM Saturday Evening for the entire NWS Norton Coverage Area except Nantucket for heat indices up to 102. Those working and recreating outside should take frequent breaks in Air Conditioned comfort and drink plenty of liquids. Conditions tonight should be a bit better than previous nights and much improved on Sunday from a heat perspective..
..For Saturday, there will be higher instability across the Mid-Atlantic states to our southwest but there will remain sufficient instability, energy, forcing, and wind shear for Isolated to Scattered Strong to severe thunderstorms across much of Southern New England with the greatest risk in Southwest Massachusetts and Connecticut. The Storm Prediction Center (SPC) has placed most of Connecticut in a slight risk for severe weather and the rest of Southern New England in a marginal risk for severe weather. Timeframe is between 2 PM-12 AM Saturday. Strong to damaging winds, hail, frequent lightning and heavy downpours leading to urban and poor drainage flooding would be the main threats..
..SKYWARN Self-Activation with Amateur Radio-Call Up Nets will monitor any severe weather potential this Saturday PM and Evening. Pictures and videos of wind damage, hail, flooding etc. can be sent as a reply to this email, via our Facebook/X/Bluesky feeds or the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated. This will be the last coordination message on severe weather and heat potential as the heat wave breaks. Storm Coordination messages may be posted for soaking rainfall potential later Sunday into Tuesday for the region..
..Below is the WX1BOX Amateur Radio Log of the Thursday Evening/Early Friday AM 7/2/26-7/3/26 severe weather event, Wednesday Evening/Thursday AM 7/1/26-7/2/26 severe weather event, Tuesday 6/30/26 severe weather event, Heat Advisory Statement, Area Forecast Discussion, Enhanced Hazardous Weather Outlook, SPC Day-1 Convective Outlook and NWS Heat Safety Tips..
