Brace Yourself, Vermont: You're REALLY About To Get Slapped By Winter. Also, Not Just Vermont

 Like I noted in a post Sunday morning, it's been an incredibly warm year in Vermont.

A weather map depicting what forecasters think will
be happening Thursday morning. A strong Alberta
clipper is seen here spreading wind and snow
across the Northeast, while a blast of Arctic air
begins to rush southward into the eastern
half of the United States. 
That party is over. 

The chilly winds and snow showers, and itty bits of lake effect stuff the Green Mountain State experienced over the weekend was just a tiny morsel of what's to come.

If you love wind chills below zero, icebox temperatures, lots of wind and bursts of snow blasting into your face, this will be your week. And this could last awhile. 

Today and tomorrow, we'll muddle through with sort of chilly weather for this time of year, but nothing that out of the ordinary.  The sky will probably yield a few more snowflakes from time to time, but nothing major. 

We already had some snow in much of Vermont overnight. My place in St. Albans had 1.1 inches of surprise snow overnight.

Roads early this morning were slick in spots, and as of 7 a.m it was definitely still snowing noticeably in the northern Green Mountains and western slopes. Accumulations won't amount to all that much today, but the dustings in the mountains will continue to slowly add up. 

Tomorrow, it's rinse and repeat. Some of us might get another  dusting, a lucky few maybe an inch or two. And the northern mountains could collect up to four or five inches of fluff.

WINTER SLAMS

The cold drama starts Wednesday. A strong Alberta clipper will come at us from the west and northwest and pass through the region Thursday. 

Alberta clippers, to refresh your memory, are storms that form in or near Alberta, Canada and head southeastward toward us. They can be windy storms, but they they don't usually have all that much moisture to work with.  

They usually bring cold winds and more often than not, less than four inches of snow. 

This particular Alberta clipper will help spread frigid air through almost all of the eastern half of the nation, creating southern freezes, subzero cold in the upper Midwest, more epic lake effect snowstorms in the Great Lakes, and general winter awfulness and cold winds everywhere in the East.

An early guesstimate from the National Weather Service
in South Burlington regarding how much snow
will fall Wednesday and Thursday. It's definitely
subject to change, and I suspect this map might
underestimate how much snow might all in 
the northern and central Green Mountains. 
 As is usual with an Alberta clipper, we won't get a huge dump of snow with this one here in Vermont, but it will get somewhat snowy. .

Ahead of it, strong south winds will get cranking Wednesday, especially in the Champlain Valley. Despite the south winds, it really won't warm up much, so the precipitation that does come in will be snow. 

The storm's boisterous cold fronts will bluster through on Thursday, with more snow showers. Some of them might be squally, with briefly heavy snow and particularly gusty and erratic winds. 

So really, this whole Alberta clipper thing will make travel on the highways a bit much at times through Wednesday through Friday. 

Lower valleys like the Champlain and lower Connecticut probably won't see much new snow, maybe an inch or two. But the mountains (Read: ski areas) should benefit from several inches of snow. 

Starting Thursday and continuing through the weekend, it's going to be COLD.  The howling winter winds will continue. High temperatures Friday and during next weekend will only be in the 20s, with some areas maybe not making it out of the teens Friday. 

Lows will be in the single digits, and wind chills will certainly be below zero. If you  haven't dragged your really cold winter gear out of the closets yet, now's the time to do it. 

Sure, it usually gets cold in December, but this looks like it will definitely a stronger and more intense early December cold wave than we've gotten used to in recent years.  Though in this age of climate change, this won't be as nasty as some historic cold waves decades ago. It won't be a record-breaker.

It's beginning to look like a reinforcing shot of frigid air will come in around Sunday, so the earliest we might see any kind of warm up is more than a week away.
