Cold With Increasing Clouds Today

Hello everyone!

Today will feature cold temperatures and increasing clouds as a weak coastal storm tries to get going well to our southeast. Look for highs to range from the mid 10’s north to just above 20 in the south. Thankfully, winds will subside today so that cold won’t be quite as biting. Skies will start sunny this morning, but clouds will move in this afternoon as that system begins to develop off the New Jersey coast. There’s a chance that the immediate coast could even get a period of light snow from that system tonight, but accumulations wouldn’t exceed an inch even if that did happen.

A Chilly But Calm Day Today

Hello everyone!

Today will feature chilly temps and calm weather as a weak storm system passes by to our south. Highs will range from the lower 10’s north to the low 20’s in the south. Winds will be lighter than yesterday, but still noticeably out of the north. Morning clouds associated with that weak storm system will be thickest in southern areas, but as that system races out to sea, sunny skies will develop for the entire area by afternoon.

Gusty Winds Bring Much Cooler Air Today

Hello everyone!

Today will feature the departure of precipitation for many areas, along with the arrival of colder temperatures. Look for gusty westerly winds to result in temps falling throughout the day with readings around freezing this morning replaced by teens by this evening. Westerly winds combined with upper level dynamics leftover from yesterday’s storm will result in heavy upslope snows that will be much more widespread than usual. Several additional inches of accumulation are expected for the mountains, with snow ongoing into this evening. Some of the upslope snow showers could drift SE towards the coast, but accumulation will likely remain confined to this higher terrain. In addition to bringing cold air and upslope snow, westerly winds will bring the threat for some scattered power outages with gusts over 30 mph today. This threat will be highest where ice from yesterday’s storm remains on trees and power lines.

Snow Becomes Heavy This Afternoon As It Changes To Rain Near The Coast

Hello everyone!

Today’s forecast will be a complex one as low pressure intensifies basically right overhead. Snow is already beginning across the area this morning, and will continue to expand in coverage and intensity as we head through the middle part of the day.

Along the coast, snow will continue through the mid afternoon hours when warm air will slowly creep inland, resulting in a change to rain. This change will happen earliest along the midcoast, and latest in the Casco Bay area. Expect 3-6″ of snow for most of this area before heavy rain develops for the later part of the afternoon. The exception may be along the peninsulas of the Midcoast where warm air will invade most easily. 1-3″ can be expected there.

For inland areas, snow will last deeper into the afternoon, with the changeover coming later than at the coast. Not only will it come later, but it will be a different flavor of changeover, from snow to ice and sleet instead of snow to rain. 6-12″ of snow can be expected before ice and sleet develop this evening. Total icing of up to .2″ is expected, and while that’s not enough for power outage concerns, it will be enough to cause very slippery conditions on the roads.

In the mountains, deep cold air will remain locked in place today. An all snow event is expected north of route 2, with many locations seeing 8 to potentially 16″ of snow. The very end of the event may bring a few ice pellets or freezing raindrops, but the vast majority of the system will be snowy. Enjoy the powder at the ski areas!

Rain, snow, and mixed precip moves out this evening with NW winds bringing a shot of bitter cold air for tomorrow, along with robust upslope snow showers.

Weak Cold Front Brings Clouds And Mountain Flurries Today

Hello everyone!

Today will feature a mix of sun and clouds, with that balance shifting away from sunshine for many, especially in the mountains. A weak cold front will be passing through today, but will be lacking much forcing or moisture to cause widespread issues. That being said, mountain snow showers could result in briefly reduced visibilities midday. Most folks downwind of the mountains should stay dry, but a flurry or two can’t be ruled out. Temps will range from the low 20’s in the mountains to a few degrees above freezing near the coast.

This cold front will set the stage for our next snowstorm, which arrives tomorrow. The entire area will start with snowfall tomorrow morning as a clipper system approaches from the west. As the morning wears on, much of the coast, especially east of Brunswick, will warm above freezing resulting in rain. During the morning, a coastal secondary low will begin to develop. Where exactly this low tracks will be crucial in determining who stays snow and who changes to rain or mixed precipitation. Latest trends in model guidance point to a more westerly track of the low, which would be a warmer scenario for much of the coastal plain. However, cold air is notoriously stubborn in this area as we’ve seen countless times. It’s far too early for me to bet against the cold air’s staying power.

If you’re interested in a much more thorough analysis of the system, I styled last evening’s weather.us blog after the winter storm posts I did on here back in the day. It’s a deep dive into tomorrow’s system that explores some meteorological concepts along the way. Check it out!

Clearing Out Today

Hello everyone!

Yesterday’s snow is on its way out today, and will be replaced by sunny skies for much of the coastal plain by early this afternoon. Westerly winds will pick up behind the departing system, resulting in a classic upslope/downslope pattern for clouds, precip, and temps. Temps will range from the mid 20’s in the mountains to the mid 30’s along the coast. Clouds and snow showers will be most abundant in the mountains, though with an assist from Lake Ontario, some of that moisture could spill out onto the coastal plain with clouds and flurries possible this evening.

Moderate Snow Today

Hello everyone!

A snowstorm is on the way for today as low pressure develops to our southeast. Snow will arrive from SE to NW just after noon, with some of the immediate coastline east of Brunswick starting as a rain/snow mix. Light snow will become moderate, and occasionally even heavy this afternoon as the storm moves by offshore. Snow will taper off late tonight, though light snow could linger into tomorrow morning especially NE of Portland. Temps will range from the low 20’s north to a little above freezing on the midcoast today. Everyone cools down as the sun sets and cold air begins flowing south this evening. When that process starts, any leftover rain in the Rockland area will switch over to snow.

Here’s what I’m thinking for total accumulation. The lowest totals will be found in the CT river valley, farthest away from the rising motion and moisture associated with the storm system. The jackpot will be along the coastal plain away from the Midcoast where a few spots could pick up more than 6″. Most totals will fall between 3 and 6″ aside from the two spots mentioned (CT valley and Midcoast) where there are noteworthy inhibiting factors.

More snow and potentially some ice is in the forecast for Tuesday.
