It will potentially be an active weekend for severe weather across Southern New England. Not much change in thinking other than we have designated a time for Amateur Radio Ops start for Saturday Morning. We will detail Saturday over the next day’s coordination messages and detail Sunday’s potential as we get into the first half of the weekend.
For Saturday, the headlines depict the current severe weather potential. Key factors for Saturday’s severe weather potential and extent of strong to severe thunderstorm coverage are the following:
1.) Amount of cloud cover over the area as that will determine destabilization and level of instability for the region.
2.) Timing of the cold front through the region.
3.) Favorable factors for severe weather potential include sufficient wind shear profiles and good cooling of the atmosphere aloft along with a strong triggering mechanism with the cold front.
SKYWARN Activation with Ops at NWS Boston/Norton is possible Saturday and Sunday for the severe weather potential. Another coordination message will be posted by 900 AM Saturday Morning.
