Hello everyone!

Today will feature the arrival of cooler air as a cold front crosses the region and Canadian high pressure begins building in from the north. The front is currently working through the mountains and northeastern foothills this morning (Greenville is reporting a 20 mph NW wind behind the front while Bangor is WSW at 5 mph ahead of the front), and will make its way south during the morning. By midday, the front will have passed through the entire region and we’ll all be enjoying cool northwesterly flow.

Precipitation along the front will be moving in from the west as a weak disturbance aloft rides along the boundary. By the time that disturbance gets to our longitude, the front will have moved far enough south that the mountains are likely to stay mostly dry. Southern and central areas can expect a round of showers between roughly 8AM and 12 PM. Another wave will pass along the front later in the afternoon, and will bring another round of rain to southern NH.

Temps today will be falling across the area, so whatever you’re feeling outside now will be your high for the day. By 2 PM, the mountains will be sitting in the upper 40’s, the foothills and northeastern parts of the area in the low to mid 50’s, and far SW ME/S NH in the low to mid 60’s. By 8 PM, temps will have fallen another 5 degrees or so across the area before bottoming out in the low 30’s north and mid to upper 40’s south overnight.

For your enjoyment, here’s a loop of today’s dew point forecast showing the dry air sweeping in from north to south. What a delightful sight!
