Severe Weather Coordination Message #2 – Sunday Evening 6/14/26 Severe Weather Potential

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.
