A Vermont Summer Weekend In October

Vermont amid strangely hot, dusty weather 

All those leaf peepers from out of state who crammed themselves into Vermont this weekend probably brought their fleece jackets, knit hats, and maybe long underwear to endure the October chill while watching tree leaves die. 

The jokes on them.

They should have brought shorts, swimsuits and such since we're having a summer weekend, and early part of the week, too. 

The weather today, tomorrow and possibly Tuesday in Vermont will be normal - for July. Since it's October, the expected temperatures will almost certainly break some record highs. 

Summer redux started yesterday, with highs in the 70s to around 80. Burlington reached 81 degrees. Not quite a record high, but damn close.

The heat should peak today. The National Weather Service is going for a high of 85 today in Burlington. That would have tied the all-time record for the month of October, if not for the 86 degrees just two years ago. 

As mentioned here on Friday, this will be the third Vermont October in a row with unprecedented heat for this time of year. 

It won't be just Burlington. Record highs will envelop much of the rest of northern New England, and southern Quebec and Ontario.  Over the past couple of days, record October heat has covered a huge area around the Great Lakes, Midwest and Upper Plains in the United States and parts of Canada, including Manitoba, and the other two provinces I already mentioned. 

Climatologist Maximiliano Herrera is calling the widespread October heat "one of the most extreme events in all North American history."

Some examples, just to cherry pick: 99 degrees in Ellsworth, South Dakota (in October!); 96 in Rapid City, South Dakota and 92 degrees in Appleton, Minnesota. 

Those same areas sweltered overnight as temperatures failed to drop below 70 degrees in most of that Midwest heat zone. 

Back here in Vermont, some of that warm night air will make its way here, but it won't be quite as bad as out in the Midwest. Lows in the Champlain Valley might not get below 60 degrees tonight and Monday night. This time of year, lows should be in the mid-40s.

Monday afternoon should be almost as hot as today, with highs once again reaching record territory. Many towns will reach 80s degrees.  Depending on how fast Tuesday clouds up, there's a slight chance a couple places could reach 80. 

If Burlington has four days in a row of 80 degree weather, that'll be the most consecutive days on record of such warmth. The record is three days in that blast of heat in October, 2023. 

DROUGHT/RAIN CHANCES

Since we're in a drought, you don't want it to be hot and dry, which is precisely what's happening here. In dry times, the warmer it gets, the more efficient evaporation is. So droughts get worse than they would otherwise be when you have bouts of record heat.  

We're already seeing that this weekend. A forest fire broke out Saturday in a hard to reach place on Brownell Mountain in Williston. We had the rare, rather scary experience of seeing helicopters dropping water on the fire, like they do in those big western fires.

At last report, the fire on Brownell Mountain had not yet covered a lot of territory, and no evacuations have been ordered. 

Firefighting efforts were suspended last night after they at least partly tamped down the blaze. They'll be back at it today with the firefighting effort. 

There's obviously the risk of more fires, at least until it rains, 

 Rain will come with a cold front Tuesday and Tuesday night. As has been the case for months, this rain will by no means become a drought buster. It will be welcomed, for sure, but it will be brief Band-Aid to a drought that really needs major surgery to solve.

Early guesses are the cold front will perhaps a half inch of rain, give or take. We need much more than that to dent this drought. 

Like the rains on September 23-25, the wet weather Tuesday and Tuesday night will temporarily tamp down the fires and fire risk, but that problem will come back within a few days. 

We're stuck in the same drought weather pattern of big, huge, dry high pressure systems parking themselves over us for days on end. The next one will come in Wednesday, give us clear skies.  It will get even colder than it was this past Wednesday night, so frost and freezes are even more likely.

That's about the only normal part of the weather we're seeing here in early October. 

The big, dry high pressure will actually get reinforced around this coming Friday, so the rainless weather will once again last a long time.  After Tuesday, I don't really see any chances of rain until around October 17 or so.
