Severe Weather Coordination Message #1 – Thursday 7/28/22 Severe Weather Potential

Hello to all…

..Isolated strong to severe thunderstorms are possible Thursday Afternoon and Evening in Western, Central and Northern Massachusetts and Northwest Connecticut with strong to damaging winds, hail, frequent lightning and heavy rainfall with urban and poor drainage flooding as the main threats. The Storm Prediction Center, SPC, has placed this area in a marginal risk for severe weather for Thursday..
..SKYWARN Self-Activation will monitor the severe weather potential for Thursday..

A warm front will move through New England on Thursday bringing in more humid and somewhat warmer conditions. As this occurs, a weak cold front will swing through the area. There will be sufficient shear in the atmosphere for isolated strong to severe thunderstorm development. The key factors will be lift along the front, ability for shear to coincide with sufficient instability presuming enough heating and destabilization for isolated strong to severe thunderstorm development. As we saw this past Monday, the right combination of factors have to come into place for severe thunderstorm development or activity will be quite isolated or muted so will be monitoring these conditions as we get into Thursday to see if that overlap of instability, shear and a source of lift come together for isolated severe thunderstorms in the marginal risk area.

SKYWARN Self-Activation will monitor the severe weather potential for Thursday. Another coordination message will be posted by 1130 AM Thursday Morning. Below is the NWS Boston/Norton Area Forecast Discussion, Enhanced Hazardous Weather Outlook and SPC Day-2 Convective Outlook:
