"Coldest" Morning Of The Vermont So Far Was Right About Normal, Actually

Wednesday was a candidate for the most perfect weather
day of the year in Vermont.  Trees aren't really turning
color yet, but the recent turn to more seasonable
temperatures might encourage some foliage in the coming days.
 This morning in Burlington, Vermont, the temperature went down to 47 degrees, the first time it was under 50 degrees since June 4.  

As far as I can determine, this looks like it might be the second longest period continuously above 50 degrees on record. This year it was 108 such days. In 2021, it was 110 days. 

This also  had to be one  of the latest or possibly even the latest first 50 of the autumn on record.  After all, it has been below freezing this time of year in Burlington, according to past weather records. 

All this is to say, it might have felt chilly this morning, but temperatures were actually very close to normal for the days around the Autumn Equinox. 

Morning lows in the warmer valleys of Vermont are usually within a few degrees of 50 degrees this time of year. Away from Lake Champlain, lows this time of year are generally in the 40s, which is right where most people were at dawn today 

The perennial cold spot, Saranac Lake, New York was down to 31 degrees today, but for them, that's totally par for the course in mid-September. The cold hollows of the Northeast Kingdom were in the upper 30s, but again, yawn. 

This of course, is what we've been waiting for in oddly humid June, July, August and early September. Tuesday was about as perfect a day as you could get: Deep blue skies dotted with just a few clouds, perfectly comfortable temperatures and a pleasant light breeze. It was a strong candidate for nicest day of 2023.

The good news is, the weather looks like it will stay almost as nice as Tuesday, with of course a few hiccups and caveats. 

Today will be another nice one.  We're back to having wildfire smoke in the atmosphere due to those ongoing Canadian fires. So the sky won't be as nice a deep blue as yesterday. It will have a disappointing haze to it. The smoke is aloft, so we don't really have to worry about air quality. 

Right now there's a weird storm forming off the east coast of Florida. Looks like it will be some sort of odd hybrid between a regular storm and a tropical storm. 

The effects on the ground won't matter either way. Things should get nasty in North Carolina and Virginia by Friday night, with gusty winds, storm surges and torrential rains. 

The question is how far this thing will move north.   Early signs suggest it might get shoved off to our south by strong high pressure building strength in Quebec, but there's no guarantees.   

Initial guesses are that rain might spread into southern Vermont over the weekend, but might not make it much further north than that. But nobody knows for sure. No flooding concerns with this one, though.

This silly storm could spread high clouds across Vermont like Lee did last Friday, which could give us another round of great sunsets. Especially with a little wildfire smoke in the upper atmosphere.
