Severe Weather Coordination Message #1 – Late Wednesday PM through Late Wednesday Night 6/25/24 Severe Weather Potential

Hello to all…

..Isolated to Scattered Strong to Severe Thunderstorms are 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 between 4-11 PM Wednesday give or take a couple of 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 include:

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 weather 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.

SKYWARN Self-Activation with Amateur Radio Call-Up Nets are possible for the severe weather potential. Another coordination message will be posted by 11 AM Wednesday Morning.
