Winter Storm Departs Later Today

Hello everyone!

Today will feature the departure of our winter storm, which has brought substantial snow to much of the area overnight. Snow is still falling this morning, and is heaviest over the mountains, while lightest across parts of SW NH where dry air has moved in aloft. Warm air has worked onshore in far SE NH and along the immediate shorelines of Penobscot Bay, yet Wiscasset and Portland are both reporting snow with temps of 29 and 32 respectively as of this writing.

To our west, a band of heavy snow is organizing over New York State. This band put down a couple inches in only an hour or so here in Ithaca, and it’s moving east. This will be the last hurrah from the current storm, and it will impact Western NH later this morning, before moving into Maine early this afternoon. Everyone outside of the favored mountain upslope areas should be clear of snow by late afternoon.

Additional snow accumulations from both what’s currently falling and that final band should end up in the 2-4″ range, with potentially a little bit more in the mountains as upsloping continues into tomorrow.

High temps will range from 20 in the north to 40 in the south, though those 40 degree temps are likely to occur this morning before onshore winds turn northerly this afternoon, bringing in colder air.

A Calm Before The Next Storm Today

Hello everyone!

Today will feature relatively calm conditions ahead of our first regionally significant winter storm of the season. Expect any morning sunshine in northeastern parts of the area to be promptly replaced by clouds in the net couple hours. Temps will be on the colder side, ranging from 20 in the north to 30 along the coast. Snow will move in overnight, peaking in intensity early tomorrow morning.

A general 4-8″ is likely a good bet for most of the area, with slightly lower 2-4″ amounts east of route 1 south of Portland and south of Route 1 east of Brunswick where rain will mix in tomorrow morning. Slightly higher 8-12″ amounts are expected in the mountains, especially east-facing slopes that get some upslope enhancement.

Snow moves out of the area midday tomorrow.

Clearing Out For Most Today

Hello everyone!

Another storm has passed us by, which means that today will be back to the improvement cycle for most of the area not impacted by upsloping. Gusty NW winds will result in clearing skies downwind of the mountains, while of course the typical upslope regions will continue to see clouds and snow. The storm that brought us the snow yesterday is now explosively intensifying over the Canadian Maritimes. As it does so, it will be pushing a very cold airmass in our direction. High temps therefore will feel more like late December than mid November, ranging from 15 in the north to 30 in the south.

Early Season Snow Event Underway In The Mountains

Hello everyone!

Another early season snow event is now underway in the mountains and foothills of Western Maine and NH. Temps in the mountains and upper foothills are hovering right around or a little below freezing, with temps in the upper 30’s to low 40’s along the coast. This general temperature distribution will be the name of the game for most of the day today as snow accumulates in the mountains and the coast gets treated to a chilly rain. As far as accumulations go, the peaks should see a solid 4-8″, with amounts closer to 3-6″ in the valleys. 2-4″ is a good bet for the upper foothills, with a coating-2″ for the lower foothills (closer to the coast).

Rain and snow will depart later this afternoon as gusty NW winds develop.

Clouds Increase Today Ahead Of Our Next Storm System

Hello everyone!

Our rapid fire pattern continues this week with barely more than a day or two between storms. High pressure will be vacating the area today, as our next storm forms in the Gulf of Mexico. As a result, morning sunshine will give way to afternoon/evening cloudiness. Winds will generally be on the lighter side, and precip will hold off until tomorrow. Look for high temps ranging from 30 in the mountains to 45 along the coast.

This next storm will bring more snow to the mountains, with rain expected along the coast.

Clear And Chilly Today

Hello everyone!

Today will feature clear skies for most of the area downwind of the mountains, along with chilly temps as cold air continues to pour into the region from Canada. High temps will range from the mid 20’s in the north to the mid 30’s in the south. A few flakes could fall out of patchy upslope cloudiness in the mountains, but otherwise dry weather will prevail.

Back To The Upslope/Downslope Pattern Today

Hello everyone!

The storm system that brought a myriad of precipitation types to the area last night is departing the region this morning. As low pressure strengthens in the Canadian Maritimes, winds will pick up out of the NW today, which will set up our classic upslope/downslope pattern. Expect residual mixed precipitation to change over to snow in the mountains, with upslope snow showers continuing through the day providing an additional inch or two of accumulation. Downwind of the mountains, temps will fall sharply as skies clear and drier conditions return.

Temps in the low 30’s in the mountains and mid 40’s along the coast this morning will fall into the mid 20’s in the mountains and mid 30’s along the coast by this evening.
