Cold Snap Is Here, Thankfully Summer Returns In Just A Few Days

The last and strongest of series of cold fronts blasted through Vermont overnight with a gush of strong north winds and ever so brief downpours. Welcome now to October in June.  

Or maybe January if you're way up high.  When you get these weird bowling balls of chilly air coming down from the North Pole this time of year, it tends to stay warmish in the valleys, but the mountains cool off fast. 

And they did.

What a lovely morning to report from atop Mount Washington. As of early this morning, the temperature there was 28 degrees with dense fog as they're in the clouds. Rime ice is forming up there.  The wind on Mount Washington was northwest at 62 mph, yielding a wind chill of 8 above.

I looked at the Whiteface Mountain, New York webcam   at an elevation of about 4,800 feet and of course all I could see was dense fog. They're in the clouds. I couldn't tell if that was ice or water on the camera lens. 

It wasn't quite so bad atop Vermont's Mount Mansfield, and so far at least, it appears to be too warm for snow up there.   At last check this morning, it was 39 degrees up there with a northwest wind gusting to 55 mph. 

As advertised, today is not a great day for a hike.'

Even in the lowlands. We're starting the day with temperatures that actually aren't that unusual for this time of year. Most of us were in the upper 40s to low 50s as dawn broke.

Trouble is, temperatures just won't rise much by afternoon. Especially in northern Vermont, which has a higher chance of rain today.

Most of the area north of Route 2 will rain lightly most of the day, with a stiff northwest wind holding temperatures in the low 50s..We're still actually looking at "high" temperatures in the 40s in parts of the Northeast Kingdom.

With such low temperatures today, we're lucky skies will remain partly to mostly cloudy tonight and a breeze will continue. That will prevent anyone from getting a late season frost.

We in northern New England can consider ourselves the odd man out, given how many places are having record breaking heat waves.

France, Germany and other western European nations are expecting the hottest temperatures for so early in the season over this weekend.  France already logged temperatures as high as 104 degrees Friday, which for them is the earliest recorded.

The hot dry weather has already helped set forests ablaze in Spain and Germany.

Heat is also building once again in the middle of the United States. Head advisories and warnings are in effect for places as far north as the Canadian border in North Dakota. 

Even the normally sultry South is expecting worse heat than normal, with heat advisories from Louisiana to Florida. Orlando, Florida could hit 100 degrees for the first time in several years today.  It's as bad a day to visit Disney as it is for a hike in Vermont.

Places like Mississippi and Alabama are expecting highs in the 95 to 100 degree range daily for at least a week.

That heat dome in the middle of the nation will actually help free us from the current autumn in summer weekend.  It'll wobble a little east, and the overall jet stream pattern will flatten.  That will allow warmer air to sneak in from the west as the week goes on.

Thankfully, the bulk of the heat will stay well to our west. It'll gradually warm up, and from Wednesday onward into next weekend, we should see highs temperatures in the low 80s, which would actually be a wee bit warmer than normal for late June. Won't that be nice?
