Good day everyone!
The Storm Prediction Center indicates a SLIGHT risk for Severe Thunderstorms in the Day 3 Convective Outlook.
Elsewhere, a powerful Nor’easter / Coastal Development will be getting underway within the next 24 hours. A low pressure area over the northern regions, will phase with a developing system over the SE around or south of the VA area. Once phased, this low will begin to deepen as it continues to move NEWD.
Given the nature of the pressure gradient in the northern portion of this system, residents within the onshore easterly, to NE flow can expect sustained winds of around 55-65 mph. Waves are forecast to around 18-24 ft over the Gulf of Maine, and 27-33 ft around 40N, SEWD to 65W.
Given that there will be snow on the NW side of this, I expect blizzard conditions from Mass., northward, with some of the worst conditions affecting the Cape Cod area.
Based on the forecast wave height, wind velocity and fetch, Residents along these areas may experience beach erosion, and coastal flooding at the time of high tide. ALL Marine traffic should remain inport or in safe harbor. I cannot rule out some widespread power outages.
I will have further updates on this developing situation as warranted.
The long range GFS is still consistent with another shot of Arctic air for the eastern portion of the U.S. near mid month, with freezing temperatures reaching possibly to the Florida Panhandle.
Have a great day!
