Severe Weather Coordination Message #2 – Wednesday 7/14/21 Severe Weather Potential
Hello to all…
..Isolated to scattered strong to severe thunderstorms are possible to likely across Western, Central and interior Northeast Massachusetts and much of Connecticut Wednesday Afternoon and Evening. Strong to damaging winds, hail, frequent lightning and heavy rainfall with urban and poor drainage flooding are the primary threats..
..The Storm Prediction Center (SPC) has placed Western Massachusetts and Northwest Connecticut in a Slight risk for severe weather with Central and interior Northeast Massachusetts from the Boston area north and west, much of Connecticut and Northwest Rhode Island in a marginal risk for severe weather for Wednesday Afternoon and Evening. The timeframe for the severe weather potential is now expected to be a bit later, between 3-10 PM EDT Wednesday..
..SKYWARN Self-Activation will monitor the severe weather potential for Wednesday Afternoon and Evening..
Conditions will become warm and humid on Wednesday as a warm front will swing through Southern New England. An impulse in the atmosphere will traverse the area near or shortly after the time of peak heating resulting in isolated to scattered strong to severe thunderstorm development. The headlines depict the current thinking which includes an upgrade to parts of the Western Massachusetts and Northwest CT into a slight risk for severe weather for today. Key factors remain as follows:
1.) Any lingering cloud cover in the morning as the warm front moves through resulting in less heating and destabilization in the area.
2.) The timing of the impulse swinging through the atmosphere as a later arrival would mean less of a threat for severe weather or it would be confined to western parts of the area whereas a bit faster timing could put areas even further east at the risk for isolated to scattered strong to severe thunderstorms in the region.
SKYWARN Self-Activation will monitor the severe weather potential for Wednesday Afternoon and Evening. This will be the last coordination message as we shift into operations mode.
