Vermont, And Rest Of North Country Still On Target For Blast Of Snow Today

The latest National Weather Service snow forecast
issued this morning. Areas in yellow and orang can
expect six to 10 inches of snow. Blue areas will
be closer to five inches. 

The sky overhead as we woke up this morning was the polar opposite of yesterday's weather. 

Instead of that beautiful bluebird sky we enjoyed on Thursday. there's an ominous gray overhead.

 That's our sign that Vermont and the rest of the North Country is in for a blast of wet snow this afternoon and evening that will have some of you crying "uncle."

It's not that this storm will be much bigger than usual. Instead, it's another installment in a long, long winter. And, as we've noted previously. the timing and consistency of this thump of snow is bad. 

TIMING

You'll want to get any driving and errands done by noon today to be on the safe side

The snow should arrive in southwestern Vermont by around noon.  Along Interstate 89, the snow will start maybe around 3 or 4 p.m., give or take. The Northeast Kingdom might be able to squeak through the evening commute before the snow starts there at around 6 p.m., again, give or take. 

The snow will come in fast. Very soon after you see the first raindrops or snowflakes, the precipitation will get heavy and quickly. Those caught out on the roads will see conditions go from great to terrible in no time. 

AMOUNTS

Overall, the forecast hasn't changed much since last night. Broad brush, most of Vermont and surrounding areas should get five to 10 inches of snow. The bulk of that snow will come down within a few hours starting in the mid to late afternoon and continuing into the evening. 

If there's any changes, the amount of expected snow in the southern and central Green Mountains has ticked up by about an inch. I wouldn't be surprised if a couple spots along the east slopes of the southern or central Green Mountains come close to a foot of snow. 

Along the valley floor along Route 7 in southwest Vermont, above freezing temperatures combined with east winds might cut accumulations down closer to three or four inches. Perhaps as little as two inches around Bennington.  

When the wind comes out of the east, the wind flows downhill along the western slopes of the mountains. Air flowing downhill tends to dry out somewhat, which explains the potentially lower snow totals there. 

In the immediate Champlain Valley, the precipitation might start out with a rain/snow mix, then quickly shift to all wet snow. The initial mix might keep total accumulations down to five or six inches. 

WET, HEAVY SNOW

I bring up the mix of rain at the start west of the Green Mountains because of an interesting temperature set up this morning. East of the Green Mountains, temperatures were only in the single numbers early this morning. West of the Green Mountains, temperatures were in the 28 to 33 degree range. Bennington was already at 36 degrees.

Those areas are starting warmer than we thought. Before the precipitation starts this afternoon, temperatures west of the Greens could even briefly flirt with 40, especially down by Bennington. Even eastern Vermont should get into the low 30s by the time the snow arrives. 

However, once the precipitation starts getting heavy, that should cool the atmosphere enough to change everyone over to snow fairly quickly. 

Still, temperatures during this evening's big thump of snow should stay close to 32 or 33 degrees. The bottom line is this will be a wet and heavy snow. Not the nice, gentle powdery snowfalls we've seen most of this winter. 

As I've noted before, wet snow turns into a particularly slippery ice when compacted beneath vehicle tires.  The snow will also come down at a rate of an inch or more per hour.  Some spots on the eastern slopes of the southern Green Mountains and southeastern slopes of the Adirondacks could briefly near two inches per hour.

Road crews cannot keep up with that rate of snowfall. People will be stuck on hills, slide-offs will gum up highways. Late this afternoon and evening will be an absolutely mess. I hope some of our readers were able to arrange to work at home today. 

This really is a dynamic storm, judging from the tornadoes it spun off yesterday in Illinois and Indiana. Here in Vermont, I think we have a low, but not zero chance of seeing some thunder snow this evening, especially south. 

As we mentioned yesterday, the snow will turn much lighter and drier in consistency later tonight a Saturday morning. A new storm near the New England coast will steal most of the atmospheric energy later today and whisk it quickly eastward out into the Atlantic Ocean. 

It won't be such a bad day tomorrow with clouds, and maybe some light snow especially in the mountains. There could even by a little sun north late in the day. 

We're still watching that nor'easter for Sunday night and Monday. It still looks like it will miss us here in Vermont.  We'll update after we get through today's mess.
