Heat & Severe Weather Coordination Message #3 – Thursday 6/20/24 Severe Weather/Flood Potential
Hello to all…
..An intense heat wave continues to affect much of the region away from the immediate coast through Thursday with the intense heat breaking in many areas except for portions of Western Massachusetts and all of Northern Connecticut on Friday though it will still be humid in areas where cooler conditions occur. From a heat perspective, this message is to get the word out on heat safety which is to drink plenty of liquids, take breaks if working outdoors and seek cooler places to avoid heat related illnesses..
..Isolated to Scattered Strong to Severe thunderstorm potential will increase starting Thursday with the Storm Prediction Center (SPC) placing Western Massachusetts in a slight risk for severe weather and much of the rest of Southern New England away from the coast in a marginal risk for severe weather. Strong to damaging winds, hail, frequent lightning and heavy downpours leading to urban and poor drainage flooding are the main threats. Timing will be during Thursday Afternoon through early Evening..
..A Heat Advisory is in effect through 7 PM Friday for Northern Connecticut, Hampshire, and Hampden Counties of Massachusetts for heat indices up to 100 expected..
..A Heat Advisory is in effect through 7 PM Thursday for Franklin, Worcester, Middlesex, Essex, Suffolk, Norfolk, North-Central Bristol, North-Central Plymouth Counties of Massachusetts, Providence, Kent and Bristol Counties of Rhode Island for heat indices up to 101 expected..
..Areas outside of the heat advisories will still be warm and humid so taking additional heat precautions would be reasonable to take in these areas..
..Looking ahead, Amateur Radio Field Day weekend takes place Friday through Sunday of this week. At this time, it looks warm and humid but not as hot as during the week but there continues to be the potential for thunderstorms and an attendant lightning risk. Other specifics won’t be known until later this week. Amateur Radio Field Day weather/severe weather coordination messages will be started on Thursday and severe weather potential for Thursday will be covered as part of that message..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible on Thursday Afternoon and Evening for the severe weather and flood potential. Pictures and videos of storm damage can be sent as a reply to this message, via the WX1BOX Facebook and Twitter feeds or via the email address pics@nsradio.org with credit given to the spotter unless otherwise indicated..
The headlines above depict the current thinking on the heat wave with an earlier ending on Friday for areas away from Northern Connecticut and Western Massachusetts. Heat Safety information is also included this message as the final link in the message.
Turning the attention to the severe weather potential for Thursday, much will depend on a back-door cold front and some cooling aloft to tap into high instability levels. Shear is not very strong but instability will be high and some cooling aloft from the backdoor cold front may allow for some isolated to scattered strong to severe thunderstorms. The greatest risk will be in the interior with northern and western Massachusetts and Northwest Connecticut at a somewhat higher risk. Heavy downpours and flooding may be a bit of a greater threat given the high humidity levels and that will also be monitored. More details on this severe weather potential will be posted either later Wednesday Evening or as part of the Amateur Radio Field Day weather coordination messages will start on Thursday.
