Hello and good day to you, southeastern Vermonters! The heat and humidity from earlier this week is in the process of being swept seaward as a more zonal (i.e. west to east) flow in the upper levels of our atmosphere is pushing into New England over the next several days.
In this transition, Wednesday will feature scattered showers and thunderstorms as the incoming drier and cooler air converges with the outgoing warmer and more humid air. This activity will clear our region by Thursday, by which time high pressure will start to nose eastward into Vermont.
Cooler and more seasonal temperatures, much lower humidity, and increasing sunshine will produce a long fair-weather stretch into early next week. The only chance for showers from Thursday to next Tuesday appears to be Sunday evening, when a front looks to cross the region and introduce another shot of drier air.
With our weekly outlook in tow, let’s look at the dailies!
For Wednesday, a cold front will approach the region from our northwest, pressing southeast into very warm and humid conditions in Windham County. There will be plenty of instability present, and with incoming lift in the atmosphere and lots of moisture, scattered showers and thunderstorms will form as early as late morning and into the afternoon.
Some storms may become strong to severe, and may produce isolated damaging wind gusts, hail, and torrential rain. It will be mostly cloudy with highs in the 75-80 degree range.
As the front continues through the region, some additional showers or storms are possible Wednesday evening before midnight. Lows will drop into the upper 50s to low 60s as drier air begins to push in by Thursday morning.
For Thursday, high pressure will begin to creep into the region, which will produce mostly sunny skies and lower humidity. Highs will reach the mid 70s to low 80s with a light north wind, and lows will drop into the 55-60 degree range under mostly clear skies.
Friday and Saturday look like duplicates of each other, as high pressure moves closer and crests over southern Vermont into the weekend. Expect mostly sunny skies, calm conditions, low humidity, and highs in the upper 70s to low 80s and lows in the upper 50s to low 60s for both days.
By Sunday, a brief increase in humidity will make things feel a tad stickier, and an isolated shower is possible late in the day. Otherwise, we should see partly to mostly sunny skies with highs in the mid 70s to low 80s, with lows near 60 degrees.
Monday and Tuesday look to be drier and sunny with similar highs and lows — a beautiful broken record, if you ask me.
Have a great week!
