Detailed Discussion

A cold front settled south yesterday, inviting a freshening northwest wind, and pulling cool air over us, even as the sun found more and more room between the decreasing clouds. It was clear through northern areas most of the night, sending temperatures into the 30s in the colder spots, dipping to 30 degrees at Saranac Lake, NY. However, the cold front stumbled and stalled to our south overnight, while a minor storm tracked east through PA, and is splashing through southern New England this morning with rain and showers. This is close enough that high clouds have spread north through much of the region, thicker through southern areas, with a few showers through MA edging north into the southern-most counties of VT and NH, mainly south of Rt. 9. By midday, the storm should be near Cape Cod, heading east into the Atlantic, bringing the showers to an end. This morning’s clouds will follow suit, giving way to increasing amounts of sunshine from west to east later this morning, from the Green Mountains west, and this afternoon to the east. Meanwhile, a large dome of high pressure running from James Bay in northwest Quebec, south to the Great Lakes, builds gradually east, with fresh north and northwest winds as it approaches today, so that in spite of the sunshine, temperatures will be limited to the 60s for highs. This evening, the winds diminish to light, and with the clearing skies it means another chilly night, with 40s, 30s once again in the coldest mountain valleys, where there’s an outside chance of spotty frost. Those winds stir up again tomorrow, though nothing all that strong, keeping us mostly sunny and a bit cool, followed by another clear, crisp night Friday night. That sets the stage for the weekend, starting with sunshine Saturday, and the beginnings of a warming trend, highs ranging through the 70s. A few clouds will mix in on Sunday, but temperatures continue to climb, reaching the upper 70s to low 80s. Partly sunny, seasonably warm weather extends into early next week.
