One More Hot Day, But The Big Vermont (Temporary) Cool Down Is Just Starting

Our outdoor living summer living space in St. Albans,
Vermont. It looks like the weather will be conducive
to enjoying it most of the time for the next week. 

It was another warm, stuffy night in Vermont, and it will be another hot one today. 

But the heat is starting to wane. It will be slow at first. Today, you'll barely notice the improvement. But the cool down will pick up the pace within the next day or two.  

But that doesn't mean summer is over. More warm weather is on the way.  

It got to 91 degrees in Burlington Monday, the 12th time it has gotten to 90 this year. Springfield had its 13th such reading of the year.  

It's also highly likely July, 2025 will be one of Burlington's top 10 hottest Julys. That would make it three Julys in a row that are in the top ten hottest. 

Since June was tied for seventh warmest, we might well have one of our hottest summers on record. If August is warm.  These aren't your grandparents' Vermont summers, that's for sure. 

August will start off cool, but not necessarily stay that way. More on that in a bit.

TODAY

Even though temperatures before dawn in some areas like the Champlain Valley were in the 70s, it won't necessarily be another 90 degree day. The air flow has shifted into the northwest, starting the change in the weather, 

A weak disturbance in that northwest flow has brought air that's a touch cooler than yesterday. Maybe. And if it is cooler, it'll just be by a degree or two.  I give Burlington less than a 50/50 shot of making it to 90 degrees again today. But who knows?  

That allegedly cooler air today won't really make it into southern Vermont, so Springfield has a good shot at seeing their 14th day of the year to reach 90 degrees.  

I suppose there could be an isolated shower or rumble of thunder this afternoon, but don't count on it. Despite the relative warmth and humidity the ingredients just aren't there.

WEDNESDAY

The "real" cold front should come through tomorrow to drop our temperatures. But it will come through in pieces. That means the front probably won't be able to create much of an organized line of big storms to mark the change.

Instead there will probably be a broken batch of scattered showers and storms  coming through. They will be hit and miss.  Some places won't see any rain at all. A small minority of us will see a nice but fairly brief torrential downpour. The chances of a severe storm are not zero, but don't count on any barn busters. If there is something rambunctious, it's most likely south of Route 4. 

Most of us will just have light rains coming from the cold front. Aside from the few places bullseyed by the few real storms we'll see, count on a quarter inch or less of rain. As noted, some rain gauges will remain dry. 

 It'll still be fairly warm and muggy. In fact, some southern Vermont towns like Springfield could hit 90 one last time. But some of us, especially in the north, will start to feel a change in the air later in the day.

THURSDAY

It now looks like the flip to cooler and drier air has some complications. Wednesday's cold front looks like it will get hung up in southern New England temporarily, and a ripple of a storm will probably form along it.

This thing looks like it will dump a huge boatload of rain on southern New England and the Mid-Atlantic States, possibly causing some flooding.

Some of the models are throwing the rain back northward for a time on Thursday. Far southern Vermont could end up with a drenching rain on Thursday. Even though it's only a couple days away, we still don't know for sure whether that will happen, so forecasters will have to keep an eye on it. 

It's a little dry in southern Vermont, so if a good soaking does manage to materialize, that would be a good thing, actually. 

We also don't know yet how far north the rain will get. There's still a good chance it won't rain at all in the north. But it might not be quite as sunny up there as we originally thought.

We do know everyone in Vermont will find the air much cooler Thursday. And much less humid, at least  in the north.

BEYOND THURSDAY

The weather does look delightful Friday through Sunday, at least mostly.

The air will be super dry and comfortable through that period. It should be sunny, too. Delightful! Except for the risk of wildfire smoke. Since the air is coming from Canada, and central Canada is still burning, we get smoke. 

It's a little early to know how much smoke we'll see, but this pleasant spell of weather might not feature nice blue skies, but some haze.

I keep saying it's going to be cool toward Friday and Saturday but not really. The nights will have a bit o a chill, getting into the 40s in many places and low 50s in the Champlain Valley. But daytimes will reach the comfortable 70s.

Temperatures should get quite warm again starting Sunday and continuing much of next week. I don't know if we'll have more 90 degree weather. That remains to be seen. But summer ain't over in Vermont!
