Those clouds should break up a little bit as we go through the day. The blue skies will be dotted by a few pretty clouds much of their day.
September usually brings big bubbles of high pressure drifting by. Those feature spells of bright, sunny, cool weather, interspersed with cloudy periods. Those are the cold fronts that separate the big bubbles of high pressure.
The problem is teasing out the timing of everything, and that's going to be the problem this week. The cool high pressure systems from Canada will compete with attempts by humid, warmer air making attempts to rain on us.
Let's parse it out.
TODAY
The easy part of the forecast. We'll have a gorgeous day. Mostly sunny skies and highs within a few degrees either side of 70. Cool breezes in northern Vermont will perhaps make you want to reach for the fleece jacket or hoodie, if you spend time in the shade.
SATURDAY
Very frequently now, we'll have new "coldest mornings of the year so far." We have a shot at that around dawn tomorrow. We'll start with temperatures in the 40s, with plenty of low and mid 40s away from Lake Champlain. A few of the coldest spots in the Northeast Kingdom will probably get into the upper 30s.
Places near Lake Champlain will probably stay near 50. Dense fog will lace the river valleys.
During the day, south winds will pick up, boosting temperatures well into the 70s. The winds could get a little gusty on and near Lake Champlain, so it might be a little tricky for boats on the lake.
In southern Vermont, clouds will begin to increase as a weak but wet storm moves up the Eastern Seaboard.
SUNDAY
It looks like the weak storm with its relatively heavy rain will pass south of Vermont, passing through southern New England. Clouds will cover Vermont. Meanwhile, a cold front will be coming at us from the west.
Rain will overspread southern Vermont Saturday night and Sunday morning. There could be a half inch or more of rain in Bennington and Windham counties.
NOAA's Storm Prediction Center has a marginal risk of severe storms in much of Vermont, suggesting there could be isolated instances of damaging winds. However, with all the clouds around, it's still doubtful we'll see any real thunderstorms.
The cold front is most likely to produce rain in northern Vermont. In the end, northern and southern Vermont should get at least a decent wetting, and central Vermont might slip through between the two areas of rain and get little.
This is iffy, so expect changes in the forecast. Bottom line: Not a really nice day, but how that will play out still has question marks.
MONDAY
Another big bubble of high pressure looks like it will come in with mostly clear, cool weather. Monday will hopefully be a carbon copy of Saturday. We shall see.
TUESDAY AND BEYOND
We'll be near the battleground between those cool, big high pressure systems from Canada, and the lingering hot, humid weather in the southern half of the U.S. That torrid summer weather is really hanging tough, odd for September, but we should see little if any of it.
Instead, we'll be prone to periods of rain as weather disturbances ride along the border between the cool autumn air to the north and the hot, humid air to the south.
I'm not sure, but chances are much of the rain could pass to our south. But, if we get lucky, we could also see at least one soaking rain, which would be nice. No promises there, though
It's possible the humid air could sneak in briefly, but if it does, it won't last long. Updates to next week's forecasts will seem constant, and we might not know exactly what kind of weather we'll have until the day before the weather actually hits.
