Snow Will Continue To Harass Vermont And These People Should Have Shoveled Driveway

Looking much more like winter at my  house in St.
Albans, Vermont after 6.5 inches of snow over two days.
We've still got the slow drip, drip, drip of light snow coming down this morning in much northern Vermont and that state of affairs will continue today and tonight.

There is an interesting wrinkle to that I'll get to in a bit.

I do have to note the contrast of snowfall styles in this storm. In places further south, that really got hammered, the two and three foot snow totals came mostly in a matter of hours Wednesday night and then shut off.

Here in northern Vermont, it's been a long, slow process of gradual accumulation. At my house in St. Albans, Vermont, another 1.2 inches fell overnight, giving me a total of 6.5 inches of new snow since Wednesday night.

It's still snowing a little, so some slight accumulations will be added to the total this morning.

Now the wrinkle I talked about. And you might not like this wrinkle if you're driving this afternoon and evening.

The sun angle is getting higher, and it's getting a little easier to form convective showers - you know, the tall billowing clouds that produce showers and thunderstorms in the summer.

It's too cold for rain today, but the combination of a weather disturbance embedded in the circulation of the dying nor'easter near us and the sun, means we've got a decent chance of convective snow showers this afternoon.

That actually means snow squalls.  Those squalls would most likely come in the afternoon and evening, just like those afternoon and evening thundershowers in the summer. The set up suggest these snow squalls could strike anywhere - hit and miss - but are most likely in northern New York, the Champlain Valley, southern Vermont and southern New England.

The problem with snow squalls like the kind that are a definite possibility today, is that they cut visibility to zero on the roads as the snow pours down from these things. And roads turn from wet to icy instantaneously. That's a great recipe for highway crashes and, if you're behind one of those crashes, long traffic tieups as you try to head home from work later today.

No guarantees this will happen, but it's definitely something to be on the lookout for.  Any particular snow squall won't last forever, but each one can drop a quick inch or two of snow.

Tonight, we go back to the drip, drip, drip of light snow, especially in the mountains, where there might be another couple or few inches of snow.

Finally, on Sunday and Monday, there will likely not be too much in the way of snow showers around and temperatures will remain fairly close to normal.

Forecasters are still watching the possibility of another nor'easter around Tuesday. There's a lot of ingredients coming together that would create one, but there's still wide disagreement on the computer models on whether it will hug the coast or go well out to sea and miss us here and Vermont.

Right now, meteorologists are cautiously leaning toward the "it's going to miss us" scenario, but it's still worth keeping an eye out.

Even if that nor'easter next week does miss we'll still probably get into another regime of daily, periodic snow showers during the middle of next week.
