Severe Weather Coordination Message #1 – Saturday 7/28/18 Severe Weather Potential

Hello to all…

..Isolated to scattered strong to severe thunderstorms are possible to likely across interior Southern New England today and potentially reaching areas further east into portions of Rhode Island and Eastern Massachusetts as a cold front will bring an end to the high humidity over the region. The Storm Prediction Center (SPC) has placed portions of New England and other parts of the Northeast in a marginal risk for severe weather..
..SKYWARN Activation with Ops at NWS Boston/Norton will commence by 1230 PM to monitor the severe weather potential for today..

Heating is occurring as yesterday’s convection has cleared out of the area. A cold front or trough with lesser humidity will swing through New England this afternoon and tonight. We have the heating to allow for destabilization of the atmosphere. Wind shear profiles are actually a bit stronger than they were yesterday. The key to the aerial coverage of strong to severe thunderstorms will be how much drier air in the upper levels of the atmosphere effects thunderstorm development. This drier air could make the coverage of strong to severe thunderstorms limited or very isolated. If the dry air does not stifle the development of thunderstorms, then the coverage over the area would be more substantial given the instability, wind shear, and triggering mechanisms in place.

SKYWARN Activation with Ops at NWS Boston/Norton will commence by 1230 PM to monitor the severe weather potential for today. This will be the only coordination message as we move to operations mode. Below is the NWS Boston/Norton Hazardous Weather Outlook, Enhanced Hazardous Weather Outlook and SPC Day-1 Convective Outlook:
