Severe Weather Coordination Message #2 – Wednesday 6/24/20 Severe Weather Potential

Hello to all…

..Isolated to scattered strong to possibly severe thunderstorms are possible Wednesday Afternoon and Evening particularly in central and eastern parts 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 cold front will sweep across the region this Wednesday Afternoon and early evening. This will set the stage for isolated to scattered strong to possibly a severe thunderstorm or two across the area. Key factors on this severe weather potential include:

1.) As of 1130 AM, cloud cover appear to be thinning across the area allowing for some heating and destabilization in parts of the area. If clouds can continue to thin and allow for enough instability, this would air in some strong to isolated severe thunderstorm development.
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. The cold front is currently just getting into and through Berkshire County Massachusetts as of 1130 AM this morning.

SKYWARN Self-Activation will monitor the severe weather potential for Wednesday Afternoon into early evening. This will be the last coordination message as we shift to monitoring mode. Below is the NWS Boston/Norton Area Forecast Discussion and SPC Day-1 Convective Outlook:
