Hello to all…
..A Heat Advisory is in effect through 8 PM Wednesday for heat indices of 98-99 degrees for Northern Connecticut, North-Central Rhode Island, Eastern Hampden, Southern Worcester Counties of Massachusetts and Eastern Massachusetts from North-Central Bristol and North-Central Plymouth Counties northward. Use caution in the heat today, drink plenty of liquids and find a cool spot as needed today..
..Isolated to Scattered strong to severe thunderstorms are possible for much of Southern New England except for Cape Cod and the Islands Tuesday Afternoon and Evening. 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 placed the region in a marginal risk of severe weather for Tuesday with the best chance of severe weather along and north of the Mass Pike. Timeframe is between 2-10 PM Tuesday..
..There will be additional potential for severe weather on Wednesday and this will be detailed in a future coordination message either later tonight or early Wednesday Morning depending on severe weather operations this evening..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible Tuesday. Another more complete coordination message will be posted by 1130 AM Tuesday Morning. Pictures and videos of storm damage, hail, and flooding can be sent as a reply to this email, via the WX1BOX Facebook/Twitter feeds or the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated.
Intense heat and humidity and a trigger in the atomsphere will set the stage for isolated to scattered strong to severe thunderstorms in portions of interior Southern New England. The headlines depict the current thinking. Key factors include:
1.) The greatest potential in the marginal risk area will be along and north of the Mass Pike.
2.) Ability for heating, destabilization of the atmosphere from intense heating and sufficiently strong wind shear profiles to overcome other unfavorable factors to allow for strong to severe thunderstorm development.
SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible Tuesday. Another more complete coordination message will be posted by 1130 AM Tuesday Morning. Pictures and videos of storm damage, hail, and flooding can be sent as a reply to this email, via the WX1BOX Facebook/Twitter 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 Tuesday’s severe weather potential unless a significant update to the situation occurs and time allows for an update as we shift into operations mode. There is potential for more severe weather on Wednesday and a coordination message on that potential will either be posted later this afternoon/evening and/or early Wednesday Morning.
