Severe Weather Coordination Message #2 – Late Wednesday PM/Evening/Overnight 6/26/24 Severe Weather Potential

Hello to all…

..Isolated to Scattered Strong to Severe Thunderstorms remain possible late Wednesday Afternoon into late Wednesday Night particularly over Western Massachusetts and Northern Connecticut but all of interior Southern New England should monitor the potential. 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 Southern New England in a marginal risk for severe weather. Severe weather potential will be after 4-11 PM Wednesday give or take a few hours. There could be some activity that starts earlier in the evening and also some activity beyond 11 PM into the overnight hours..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible for the severe weather potential..

Heat and Humidity will return on Wednesday in the region followed by a cold front. This cold front will not be ideally timed to take advantage of maximum instability, however, strong wind shear and other factors may allow for at least an isolated severe thunderstorm threat. The headlines depict the current thinking. Key factors remain:

1.) If the timing of the front were to speed up and be closer to the higher instability levels, the severe weather potential would increase.
2.) If a complex of severe thunderstorms were to form out west, the storms may maintain themselves better as they enter our region especially in Western Massachusetts and Northern Connecticut even with the current timing.
3.) If wind shear and other factors are able to offset lowering instability to produce at least isolated severe thunderstorms with the current timing.
4.) There could also be some activity with the pre-frontal trough in the mid to late afternoon but shear profiles won’t be as strong and there could be other mitigating factors such as lack of moisture in the mid to upper levels but this will also bear watching this afternoon and evening.

SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible for the severe weather potential. This will be the last coordination message as we move into operations mode.
