Hello to all…

..A cold front will bring the potential for isolated to scattered strong to severe thunderstorms between 6-11 PM Sunday Evening with the greatest potential in Western and Central Massachusetts and Connecticut. Strong to Damaging Winds, hail, frequent lightning and heavy downpours leading to urban and poor drainage flooding are the main threats..
..The Storm Prediction Center (SPC) has continued Western and Central Massachusetts and most of Connecticut in a slight risk for severe weather with Rhode Island and interior Northeast Massachusetts in a marginal for severe weather on Sunday Evening..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets possible if SKYWARN reportable criteria is met and/or if a severe thunderstorm warning is issued Sunday 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..

A cold front will have the potential to bring isolated to scattered strong to severe thunderstorms particularly to Connecticut and Western and Central Massachusetts but areas as far east as Rhode Island and interior Southeast Massachusetts should monitor. The headlines depict the current thinking. Key factors include:

1.) Later timing of the cold front and whether there will be sufficient instability despite strong wind shear profiles to allow for strong to severe thunderstorm development or whether strong wind shear compensates for potentially limited instability.
2.) Whether the area of strong to severe thunderstorms “splits” with one area of strong to severe thunderstorms going more into Northern New England and the other remaining south of Southern New England over the Mid-Atlantic states.

SKYWARN Self-Activation with Amateur Radio Call-Up Nets possible if SKYWARN reportable criteria is met and/or if a severe thunderstorm warning is issued Sunday 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 as we shift into operations mode.

Hello to all…

..Isolated to Scattered Strong thunderstorms with an outside chance for an isolated severe thunderstorm are possible across Rhode Island, Central and Eastern Massachusetts, though all areas should monitor from 2-9 PM Sunday Afternoon and Evening. Strong wind gusts, hail, frequent lightning and heavy downpours leading to minor urban and poor drainage flooding are the main threats..
..SKYWARN Self-Activation will monitor for any hail, strong wind gust, wind damage reports this Sunday Afternoon and Evening with Amateur Radio Call-Up Nets possible if either a severe thunderstorm warning is issued or there is a high volume of SKYWARN reportable criteria in a given area. 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 on this strong thunderstorm potential. Below is the WX1BOX report log from the isolated to scattered strong to severe thunderstorms of Saturday Evening 6/6/26, NWS Boston/Norton Area Forecast Discussion and Enhanced Hazardous Weather Outlook..

Hello to all…

..Slight changes to timing but no major changes to severe weather potential for late Saturday PM and evening..
..Intense Heat & Humidity will set the stage for isolated to scattered strong to severe thunderstorms across portions of Southern New England late Saturday Afternoon into Saturday Evening between 4 PM-11 PM, possibly 1-2 hours later in southeast parts of the area as an impulse and cold front swing through the area..
..The Storm Prediction Center (SPC) has continued most of Southern New England north and west of the I-495 corridor 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 lighting and heavy downpours leading to urban and poor drainage flooding are the main threats..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible late Saturday Afternoon and Evening for severe weather potential if a severe thunderstorm warning is issued for a given area. 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 current thinking on severe weather potential for late Saturday PM and Evening. Key factors include:
1.) There is the possibility of two rounds of severe weather potential, one between 4-6 PM and the other between 6-9 PM possibly extending into late evening through around 1 AM in portions of Southeast New England. How this evolves will determine length and severity of the severe weather potential.
2.) Later timing would typically mean less risk for severe weather but some instability parameters are present that aren’t not normally there for later evening severe weather potential and this may allow for convection to remain strong to severe even after sunset.

SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible late Saturday Afternoon and Evening for severe weather potential if a severe thunderstorm warning is issued for a given area. This will likely be the last coordination message as we shift into operations mode. 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.
