Summer of 2018 waves goodbye as deeper autumnal pattern arrives

Good day to you, denizens of the verdant Green Mountains of southern Vermont! If you're reading this column on Wednesday (its day of publication) and you enjoy summer weather, seize the present moment and get outside!

Unseasonable warmth and humidity are most likely leaving these shores until the spring of 2019, barring any anomalous mid-cold season warm surges, of which we've had a few over the past several years.

Autumn is arriving and will be preceded by a good bout of rainfall Thursday afternoon and night before we empty into a gorgeous fall weekend with ample sunshine. More rain arrives early next week, so let's jump into the details!

For Wednesday, we'll have a cold front to our north and another cold front to our west. After some early morning patchy fog, warm and humid air will be surging through southern Vermont.

Any fog will burn off, and highs will reach well into the 70s for most locations, with perhaps a few upper 70s readings in the low elevation areas that border Massachusetts. Expect partly to mostly sunny skies and an increase in cloudiness at night with lows near 60 degrees.

For Thursday, showers will be possible in the morning, but the best chance for heavier rainfall moves in during the afternoon and lasts into the night.

Anywhere from a half inch up to 1.5 inches of rainfall is possible, depending on which towns get under some of the heavier downpours. A rumble of thunder can't be ruled out either.

Highs will be in the 60s, and lows will drop into the 40s at night as showers start to taper off by midnight, or during the pre-dawn hours of Friday morning.

For Friday, we will witness the first day of our new pattern shift into deeper autumn. Partly sunny skies can be expected on average, and northwest winds could gust to 25 mph with fresh cold air advection.

Highs will rise only into the low 50s and some higher elevations may not crest 50 degrees. Lows will plummet into the mid to upper 30s under clear skies.

For the weekend, expect mostly sunny skies and chilly conditions with highs either side of 50 degrees both days. A reinforcing high pressure ridge noses in Saturday night and with clear skies, a Frost Advisory will likely be posted for Windham County with lows in the low to mid 30s.

Clouds increase Sunday night with lows only in the 40s. Another storm races through the Great Lakes to our north early next week and will drag more rainfall through the region, Showers likely last into Tuesday with highs in the low to mid 50s. Have a great week!
