Forecast Discussion
The Great Lakes low pressure has spawned a secondary coastal low off the Delmarva Peninsula, which will travel up the coast and pass just to the southeast, right off the coast of Cape Cod. The Great Lakes low will move quickly east, propelled by strong high pressure descending from Canada. The secondary low will dissolve into the larger, more powerful low. As a result, the complex system will maintain lots of moisture and precipitation will continue through the night. As the powerful low moves east, it will sweep an arctic cold front through the region late this afternoon, plunging temperatures into the sub zero range tonight. A shortly lived lull in winds will occur today, as the center of the low passes overhead. However, as the strong high pressure forces its way south, and the powerful low continues on its eastward track, moving up into the Canadian Maritimes, the pressure gradient will tighten significantly, and winds will increase quickly and drastically. Overnight, winds will shift to the NW, and that icy air will filter swiftly into the region, especially on winds sustained at 70-100 mph, with gusts well over the century mark. Tomorrow, precipitation will be mainly upslope snow showers, as moisture is pushed up and over the mountains. Winds will sustain at 70-100 through tonight and tomorrow. In combination with temperatures in the mid teens below zero, a wind chill warning will be in effect for the higher summits from 7 pm through the forecast period. Strong winds, plenty of snow, and freezing fog will produce white out conditions on the summits through the forecast period.
