Next Storm Mostly A Southern Vermont Snow, One After That More Wide Ranging?

Latest snowfall prediction map from the National Weather
Service in South Burlington. Still shows a moderate
snowfall south, light north Sunday night. If forecast
trends continue, meteorologists might need to trim
back forecast totals a bit.  
 The snow and, in a few areas, mixed precipitation that came down Thursday night and Friday is definitely over. We get a break to either shovel the snow or play in it today before the next storm arrives.

I have noticed just a tiny bit of freezing drizzle in the air early this morning in St. Albans, Vermont. I'm sure there's other patches of, what? frizzle? here and there. So be careful driving or walking on untreated surfaces. There's already plenty of ice underfoot from water that froze last night. 

Lake Champlain is also remarkably open and unfrozen for this time of year. Some lake effect light snow and flurries have been reported in southern Chittenden and parts of Addison counties. 

Next up: Sunday night's expected snowfall. 

If anything, forecasts overnight have nudged the path of the storm even a little more south of what predictions were on Friday. Though surprises are inevitable, this is looking more and more like a southern Vermont event.

A winter storm watch is still up for the southern four counties of Vermont, and on up into Orange County. Despite the fact that this storm will start tomorrow afternoon, there's been no upgrade yet to either a winter storm warning or advisory. 

In order to issue a winter storm warning, the National Weather Service in Vermont has to be pretty confident the system will dump at least seven inches of snow. So far, the forecasts are borderline on this one. 

There might be seven inches of snow in the watch area, but it'll be close. Updated guidance will come in today to help forecasters make a decision. So far, that guidance has been slightly trimming back snow totals. If that continues, the forecast map for snowfall in this post might end up being too optimistic for accumulations. 

In any event, this storm is going to be another fast mover, so it won't stick around long enough to dump a lot  of snow. But it will still probably be nice for central and southern Vermont ski resorts, as a half a foot of snow isn't bad for them

Further north, areas along and east of the Green Mountains still look like they might be in for three or four inches of snow, at least according to current forecasts.

The northern Champlain Valley is a bit of a wild card at the moment. It's pretty apparent this won't be any kind of big storm up there. However, there's still questions if that section of Vermont can eek out two to four inches of snow, or will it be only an inch or so?  Not sure yet on that one. 

Timing wise, it looks like the snow will come into Vermont mid to late afternoon Sunday and be out of our hair by Monday afternoon. 

Between that storm and the next larger one, Tuesday could be a bit unsettled with some snow showers, possibly briefly heavy-ish, with a weak little thing passing through. 

STORM #2

Kind of like the more immediate storm Sunday night, forecasts for the next fairly significant one have shifted a tiny bit south, too. That might mean less mix and more snow for at least parts of Vermont. But for now, snow, sleet, freezing rain and rain are still on the table for that storm that will mostly hit around Wednesday night and Thursday. 

This far out, there's still a lot of questions about intensity, path, how much snow, how much mix, so take tuned!
