I do hope you're having a good moment when your eyes meet this column today! We'll be encountering some changeable (and colder) weather as we head toward Thanksgiving. High pressure and a brief warming trend will dominate the Wednesday-through-Saturday period. Thereafter, we will witness a step down in temperatures and an increase in wet (and potentially white) weather Sunday into Monday, at least.
With that summary in mind, let's jump into the daily details.
For Wednesday, we will be transitioning out of the rainy Tuesday we just endured. While fair weather will be trying to nose its way back into our collective lives, Wednesday is really a transition day. Broad upper-level low pressure will be moving through and out of southern Vermont on this day, and as such, it will be marked by more cloudiness than sunshine. In addition, some light scattered showers are possible during the day. High temperatures should reach into the upper 40s to near 50 degrees. Low temps that evening will drop into the 30s as skies continue to slowly clear.
For the period of Thursday through Saturday, we should enjoy high-pressure weather with calm, mostly sunny/clear, and pleasant conditions. High temperatures should range from the low 50s on average Thursday, and the mid to upper 50s Friday and Saturday. Low temperatures will dip down into the 30s on these evenings.
As the weekend approaches, a northern Plains blizzard is forecast to rage and track east-northeast into the Great Lakes region. As this happens, the storm will occlude, which means its center gets cut off from an inward supply of warm, moist air, and it begins to die. If conditions are right, this setup tends to spawn low-pressure development along the East Coast, which is expected at this time. In addition, the storm's cold front will be passing through our area.
In practical terms, all of this means that we can expect colder temperatures and more inclement weather to arrive to our region by Sunday into early next week. Highs in the low 40s Sunday, and highs only in the mid to upper 30s by next Monday will lead to periods of rain showers, and snow showers for some, especially in the high-terrain areas of Windham County.
As of now, Thanksgiving looks dry, but I'll update you next week, which I hope is good for you!
