Severe Weather Coordination Message #1 – Wednesday 7/31/19 Severe Weather Potential

Hello to all…

..Isolated to scattered strong to severe thunderstorms possible to likely today, Wednesday 7/31/19, in the afternoon and evening across much of Southern New England. Strong to damaging winds, hail, frequent lightning and heavy rainfall with the potential for urban to poor drainage flooding are the main threats. The Storm Prediction Center, SPC, has placed all of Southern New England in a marginal risk for severe weather for today..
..SKYWARN Activation with Ops at NWS Boston/Norton will commence at 230 PM through 9-10 PM today, Wednesday, 7/31/19 for the severe weather potential..

A cold front will make its way through Southern New England during the afternoon and evening hours. Strong heating will lead to high levels of instability. Winds shear will be marginal and cooling aloft is marginal. Those factors will preclude a more widespread severe weather event but isolated to scattered strong to severe thunderstorms should be more widespread than what was seen in the last few days with the main threats as listed in the headlines. The cold front will move through the region tonight and Thursday bringing less humid and a bit cooler conditions.

SKYWARN Activation with Ops at NWS Boston/Norton will commence at 230 PM through 9-10 PM for the severe weather potential. This will be the only coordination message on this severe weather potential.
