Hello to all…
..Isolated to Scattered Strong to Severe Thunderstorms are possible in much of Southern New England now based on latest model trends with the greatest risk across Western and Northern Massachusetts through Northwest Connecticut between 2-10 PM ET Tuesday Afternoon and Evening..
..The Storm Prediction Center (SPC) has placed Western & Central Massachusetts and Northwest Connecticut in an upgraded slight risk for severe weather with the rest of Southern New England in a marginal risk for severe weather. SPC has also stated a 60% chance of a watch for portions of the area per their latest Mesoscale Convective Discussion. Strong to damaging winds, hail, frequent lightning and heavy downpours with potential urban and poor drainage flooding are the main threats..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets possible for any isolated to scattered strong to severe thunderstorm potential after 2 PM Tuesday. 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 Tuesday PM and Evening across Southern New England. Key factors include:
1.) Forcing/trigger and that is sufficient or can be overcome by favorable instability and wind shear to allow for isolated to scattered strong to severe thunderstorm development.
2.) Overlap of the forcing/trigger near or shortly after the time for peak heating to allow for strong to severe thunderstorm development.
3.) Eastward and southward extent of the strong to severe thunderstorm potential based on key factors 1 and 2.
