Detailed Discussion
This week offers a relief from the sweltering heat and humidity of last week. Last week ended with high topping out in the 90s, but after a gradual cooling trend, this week ends seasonably cool with maximum temperatures through the 70s. A clockwise circulation over Bermuda was relentlessly pushing tropical conditions into the northeast. This week, repeated fronts will knock this high out of place and introduce cooler, Canadian air, beginning with a weak front moving through tonight.
High pressure has controlled our atmosphere keeping skies mostly clear and dry overnight, but will also create a light southwest winds that will lead to a surge of moisture into the northeast through the early parts of this afternoon, becoming muggy southwest, in tandem with increasing clouds from the west. The south to southeast winds will be especially strong over Lake Champlain where wills funnel through the Champlain valley, reaching winds speeds of 20 to 25 mph this afternoon.
Drab morning conditions of fog and broken clouds, especially north, yet comfortable with low humidity. Clouds will dissipate though the early morning as high pressure builds in from the southwest, becoming partly sunny by the afternoon and hazy with some wildfire smoke in the upper atmosphere. High pressure will begin to decay, making room for low pressure and a cold front to push in this evening. Models have been holding back rain later with each new run. Beginning in the eastern Adirondacks and southern Quebec, scattered showers will develop early this evening then spread over the Upper Greens as heavy rain showers and thunderstorms after dark, mainly north of route 4, before transitioning into New Hampshire around midnight.
Tuesday looks drier and cooler behind the fronts, and clouds will gradually clear during the day through Wednesday. Another front pushed through overnight Wednesday into Thursday, and more wet weather Thursday into Friday with the rest of the week looking much cooler. Temperatures on Friday and into the Weekend look seasonable cooler, with high across Northern New England only in the 70s.
