Here comes the Autumns first big cold front
Right on cue. We spoke about this potential a few days ago when we noted the medium range forecast models suggesting the presence of high latitude ridging and blocking. These some models now agree that a significant cold front will shift from the Great Lakes and Central United States through the Northeastern United States this weekend; plowing through our area from Saturday Night into Sunday. Showers and some thunderstorms are possible with its passage, right on the periphery of a major mid and upper level trough.
The temperature different won’t really be felt on Saturday despite the fronts passage. Initially warmer air, streaming in with a southerly flow ahead of the front, will keep temperatures in the 60’s and 70’s on Saturday. After some showers and maybe an isolated storm with gusty winds, the difference will become noticeable as winds shift to west-northwesterly and much, much cooler air begins moving in aloft.
