Severe Weather Coordination Message #1 – Wednesday 6/24/20 Severe Weather Potential

Hello to all…

..Isolated to scattered strong to severe thunderstorms are possible Wednesday Afternoon and Evening across much of Southern New England except for Cape Cod and the Islands. Strong to damaging winds, hail, and torrential rainfall with the potential for urban and poor drainage flooding are the main threats. Severe weather potential timeframe is between 12-7 PM Wednesday..
..SKYWARN Self-Activation will monitor the severe weather potential for Wednesday Afternoon into early evening..

A pre-frontal trough will swing through the area Wednesday Morning bringing with it heavy showers and a few isolated thunderstorms across Western New England. A second and possibly more potent round of thunderstorms with an isolated to scattered strong to severe thunderstorm risk is possible Wednesday Afternoon into early evening. Key factors on this severe weather potential include:

1.) Any clouds and showers and thunderstorms in the morning clearing the region allowing more heating and destabilization during the mid to late morning and early afternoon hours.
2.) Wind fields are marginal but if enough instability can develop that will allow for the development of isolated to scattered strong to severe thunderstorms.
3.) The timing of the cold front to allow for heating and destabilization for strong to severe thunderstorm development.

SKYWARN Self-Activation will monitor the severe weather potential for Wednesday Afternoon into early evening. Another coordination message will be posted by 1130 AM Wednesday Morning. Below is the NWS Boston/Norton Area Forecast Discussion:
