Detailed Discussion
The weather pattern remains active, evident from the changeable weather from last week, and continuing into this week. The challenge will be timing your outdoor plans with the various episodes of showers, and their localized nature forcing us to be flexible when possible. The weekend was certainly a good example, as the heat and humidity from late last week was swept out by a cold front Friday night, for a more comfortable start to the weekend. A second front approached yesterday, with some off and on showers near and north of the Quebec border, edging south through the Adirondacks to about Rt. 2, while it warmed into the 80s with periods of sun elsewhere. That charged the atmosphere for an active afternoon and evening as showers and locally strong thunderstorms fired up ahead of the front, featuring some very heavy, torrential rains in places, including some brief flash flooding in parts of Rutland County, northeast toward Randolph and Bethel. 3 and a quarter inches was measured in Wallingford, south of Rutland, and 2 and a quarter in Bridgewater to the east. We find that front the morning heading east, near the NH/ME border, with most of the showers now ending, and clouds beginning to break up. Much cooler air is moving in on brisk northwest winds, so in spite of our mild start, temperatures won’t warm up much, with highs only the 60s to low 70s, some mid 70s in the warmer southern valleys. The air is even chillier above, keeping a mix of sun and clouds through the day, with just a stray mountain shower possible. Overnight, that northwest airflow, and just enough moisture should keep skies partly cloudy, finally giving way to mostly sunny skies for Tuesday. Again, this is a busy weather pattern, with a minor system approaching Wednesday, leading to some building clouds, a bit of a warming trend, and a few scattered afternoon showers, mostly from the Green Mountains west. During this time frame, a stronger impulse dropping southeast from the Canadian Rockies dives into the Midwest Wednesday, strengthening into an unusually strong storm for this time of year, pivoting northeast Thursday with our next period of rain and showers, potentially substantial. Fortunately, it is also moving along at a pretty good clip, ending the steadiest rain Thursday night, preventing excessive rainfall. Behind it lies our next push of cool, somewhat unsettled air with a few daily, localized showers from Friday into the weekend. Nights will cool into the upper 40s and 50s, while it eases back to the upper 60s and 70s during the afternoon hours.
