Fun With Fog: Calm Weather Fills Vermont Valleys With Morning Murk

Fog filling the valleys of New England Thursday morning.

 As I think I've mentioned previously, this is peak season for morning fog in Vermont. Yeah, two peak seasons going on here, with the much more popular fall foliage gloriously underway. 

It was fun to watch the fog yesterday as it filled valleys across the region.   With the lowering sun angle, it's sometimes hard to dislodge the fog.  

That was the case yesterday, when parts of the Champlain and Connecticut River valleys, along with some other spots, stayed socked in until late morning. 

Those of us perched up on hills, like me in St. Albans, saw the sun rise and the sky stay blue form dawn to dusk. You can see the fog in the valleys, though.

The satellite photo in this post shows how the fog filled pretty much every river valley in and near Vermont. Often the Champlain Valley stays clear, as it's such a broad valley that little hints of breezes keep up all night, dispersing the fog.

Amid otherwise clear skies, fog persisted over Lake Champlain
until near noon, as viewed from a hill in St. Albans, Vermont.
Photo was taken at 11:15 a.m. Thursday.

But it was so calm yesterday that the fog formed, and persisted over the lake most of the morning. 

I have seen some instances this time of year when the fog doesn't really dissipate until late afternoon.  

Later this season, when we get into November, the even weaker sun will mean we'll have many days in which it won't necessarily be foggy, but a low overcast will keep the gloom going for days on end. 

We won't worry about that quite yet. There's almost as much fog out there this morning as there was yesterday, and things will play out almost exactly as they did on Thursday. Everybody will be in the sunshine by late morning.

A little more wind the next few nights might limit the fog a bit, but I suspect it will return amid calm, warm conditions early next week.
