| A hazy start to the day, as seen in South Burlington around 7:15 a.m looking toward the Adirondacks, promises a hot humid day. |
The humidity still wasn't that bad overnight, and temperatures were still reasonable, at least outside the Champlain Valley, where it never go below 70 degrees last night.
Now, as the morning goes on, the humidity is creeping up, and the temperature is racing upward on steady south winds.
Some mixing in the atmosphere due to those winds might make the humidity level off to kinda uncomfortable but not ridiculous levels this afternoon.
Still with the humidity up and temperatures reaching 90 or more, a heat advisory has been issued for the Champlain Valley, because there, the heat index will make it feel like it's in the mid-90s The Hudson Valley of New York is also under a head advisory. Up in Quebec. a heat warning is up for Montreal and large areas surrounding the city.
Actual temperatures will be close to that in the valley. Burlington's actual high temperature today is now forecast to be around 94 degrees. Plenty of other places in Vermont will be at or above 90. Temperatures might come close to record highs in some places. Montpelier in particular looks like they might break their record high, as the current record is only 89 degrees.
Tonight, that humidity will really pool over and near Vermont ahead of a cold front. If we're lucky, there might be a light show for people in far northern parts of the Green Mountain State. Depending on lingering instability there might be a decent amount of heat lighting visible looking up toward Quebec.
It's iffy, but maybe. If there are any Quebec storms tonight, they should stay north of the border until we get close to dawn.
That potential lightning is our preview for Friday.
FRIDAY
It looks like our cold front will come through near or before noon in the north, and in the early to mid afternoon north, which trims back our chances of severe storms.
The front will come through too early in the day for severe storms north, so the worst you can expect up there is some morning downpours and maybe some rumbles of thunder.
There could be some isolated strong, damaging wind gusts with storms Friday in southern and eastern Vermont, but it doesn't look like it will be a widespread problem. The rest of southern and eastern New England might also have a few strong to severe storms
There's not going to be a well defined cold front, so shower and even thunderstorm chances could last into the afternoon even in the north. But the afternoon in the north will be nicer than the morning. The opposite will be true south. Except the heat and humidity south will feel kinda nasty.
WEEKEND
It's turning out we've got a bit of a rinse and repeat of last weekend, with gorgeous weather Saturday and Sunday, not so nice.
Saturday looks sunny and warm, with moderate humidity. It should be a wonderful day for any kind of outdoor summer activity.
Very much like this time last week, the forecast for Sunday has now shifted.
At least as it stands now, what was once expected to be a minor disturbance causing the risk of widely scattered showers, mostly south, now looks a little more substantial statewide.
There's still some debate as to whether Sunday's rain will be hit and miss and mostly light except for a few local downpours, or pretty widespread and on the heavier side.
Much like last Sunday, the cause will be a hard to forecast weak disturbance from the west interacting with a cold front to set off rte showers and storms,
However, unless something in the forecast changes substantially, it looks like we'll once again avoid the any real flash flooding, the kind that has causes so many problems in the U.S this summer.
Unlike last Sunday, the cold front, such as it is, will be so weak that Monday will actually be warmer than Sunday. It fact, Monday at this point looks borderline hot. It won't be until later Tuesday or Wednesday before the big pattern change arrives to give us another big autumnal cool down.
