Saturday Evening Vermont Storm Update: No Big Changes To Dangerous Forecast

Add caption

Don't let the record warm temperatures and bits of sunshine you experienced today in Vermont fool you, we are still in for a humdinger of a storm

Dangerous ice is still coming to the north of Vermont, especially the northern Champlain Valley. And far northern New York  is really going to get nailed with awful ice.

Much of the rest of Vermont is still in for some flooding.

By late afternoon, pretty heavy rain had worked itself into northern Vermont and it was gradually working its way to the south and east. That is the beginning of the end of the warmth, and the start of the freezing rain episode in the north.

The freezing rain won't start right away, but it will come tonight.

Let's set us up with what happened this afternoon. There were quite a few record highs this afternoon in New England, including around Vermont. Here are some of the records:

Burlington, Vermont: 59, beating 56 set in 1980
Montpelier, Vermont: 59, beating 52 set in 2014
Plattsburgh, New York: 53, beating 51 in 2017
Boston: 70 degrees; second warmest January day on record
Hartford, Connecticut: 67 degrees, third warmest day on record.

WHAT'S NEXT

I took this photo of the huge "Triplet Trees" in my St. Albans
back yard amid record warmth this morning. I took this possibly
final photo of the trees in case they were end up damaged or
destroyed in tonight's ice storm. I have no way
of knowing how they wil come out Hoping for the best! 

I would say there were more record highs in the North Country today than I expected. That does NOT mean it will be a little warmer than expected overnight.  So the ice is still coming.

If anything, it could possibly mean precipitation will be a tad heavier than expected, as the contrasting air masses involved with this storm are even a little more extreme than some had forecasted.

The cold air is starting to bleed in. Massena, New York, which would be the first place south of the  border with Canada to see the cold front actually saw it come through a little after 2 p.m. this afternoon, and temperatures there have been slowly falling ever since.

The cold front just barely came through around my place in St. Albans, Vermont at 5 p.m. this evening, accompanied by heavy rain. I'm writing this right at 5 p.m., and the gusty south winds we've had all day in St. Albans just turned to the northwest a couple minutes ago. The downward slide in temperature has begun.

The National Weather Service in South Burlington expects the rain to change to freezing rain in New York's St. Lawrence Valley and the northern tip of that state around 8 or 9 p.m. tonight. The northern Champlain Valley should go to freezing rain at around 10 or 11 p.m. tonight, and points south and east of there should go to freezing rain around midnight to 1 a.m. Sunday.

Places south and east of a line from a little north of Rutland to a little north of St. Johnsbury should get little if any freezing rain, if current forecasts come out right.

The low-level cold air coming down from Ontario and Quebec is about as cold as forecasts had been all along, so the freezing rain and ice damage in the north is most certainly on for later tonight and Sunday.

Forecasts for ice accumulation haven't changed much since this morning. Far northern New York still looks to get a disastrous one inch or so of ice accumulation, which would cause massive tree and power line damage.

The northern Champlain Valley is still in line to get a half inch to three quarters of an inch of ice, which will certainly also cause a lot of damage.  By the way, southern Quebec from Montreal south, and sections of Ontario are in line for a very destructive ice storm tonight, too.

There's a couple things going for us that will make a bad situation not as bad as it could be. One, instead of a long, drawn out few days of freezing rain, we'll get downpours overnight.  So much rain will come down that some of the water won't have time to freeze until it reaches the ground, or soaks in. That would cut down a little on how much ice accumulates.

There's also a chance the low level cold air could get a little thicker in altitude than forecast. If that happens, we'd get some sleet, which doesn't really accumulate on trees and power lines. That would be most likely in the far north. Pray for more sleet than expected, believe it or not. That would make things less bad than forecast. Don't count on it, though.

FLOODING

Flooding is obviously still a concern with this storm.  It's been raining pretty hard in northwestern Vermont since mid-afternoon and small streams have already become torrents, aided by snow melt in the record warm air earlier today.

Even in the ice zone, expect some flooding this evening. I notice the small streams around my area in Franklin County, Vermont are already flowing at pretty high and fast rates as of 5 p.m. Saturday.

Small stream and gully flooding will increase this evening and overnight across northern and central Vermont as the heavy rain continues.  That will translate to mainstem river flooding on Sunday. Most rivers in Vermont will at least crest at minor flood levels. Several rivers in northern and central Vermont are still expected to reach moderate flood state.  Flood watches remain in effect, obviously.

Temperatures will also stay quite warm in southern Vermont, maybe not dropping below the 55-60 range overnight.

I'll update tonight, maybe, if warranted, and try to do a comprehensive update Sunday morning. That is, if I have power. We'll see how that goes. If you don't hear from me tomorrow morning, I don't have power, and won't be able to post. I'll figure it out eventually if that happens.
