Severe Weather Coordination Message #1 – Saturday Afternoon and Early Evening 5/28/22 Severe Weather Potential

Hello to all…

..Isolated to Scattered Strong to Severe Thunderstorms are possible Saturday Afternoon into early evening any time between 12-6 PM across interior Southern New England along and north and west of the I-95 corridor. Strong to damaging winds, hail, frequent lightning, and heavy rainfall with urban and poor drainage flooding are the main threats. The Storm Prediction Center (SPC) has interior Southern New England in a marginal risk for severe weather along and north and west of the I-95 corridor..
..SKYWARN Self-Activation will monitor the severe weather potential for Saturday Afternoon and Evening..

A frontal system will cross Southern New England Saturday afternoon into the early evening with the potential for isolated to scattered strong to severe thunderstorms. The headlines depict the current thinking. Key factors include:

1.) Overnight showers and thunderstorms and their evolution to allow for clearing in the morning for heating and destabilization to increase instability levels.
2.) Cooling aloft in the atmosphere to also increase instability
3.) Overlap of instability with sufficient wind shear profiles to allow for isolated to scattered strong to severe thunderstorm development.

SKYWARN Self-Activation will monitor the severe weather potential for Saturday Afternoon and Evening. Another coordination message will be posted by 11 AM Saturday Morning. Below is the NWS Boston/Norton Area Forecast Discussion and SPC Day-2 Convective Outlook:
