I’m a third-year atmospheric science student at Cornell University who has been blogging about the weather since 2011. While I’m not officially a meteorologist, I have accumulated a bit of experience forecasting both local weather (in western Maine and New Hampshire) as well as national/international weather during my time writing for weather.us and weathermodels.com. I also have experience programming in Python, teaching concepts in weather forecasting, and communicating forecast information to general audiences.
Today will feature more of the same in terms of the cold air we’ve been seeing recently. Expect highs in the mountains to rise to near 20 today and at the coast, we’ll see temps right around freezing. A big difference compared to yesterday will be the lack of wind as high pressure builds in so at least it won’t feel quite as cold. Some clouds are around this morning in association with a weak trough moving through but those should dry up in a hurry and the only other cloud threat today will be across the north where a storm up in Canada could throw some clouds our way.
Today’s main weather story will be the wind. Winds will gust in excess of 50 mph region wide today and a wind advisory has been put out for Maine and NH by the NWS in Gray due to the high wind threat. Up in the mountains where an inch or two of snow fell last night, watch for low visibilities to continue today as blowing and drifting takes over. A winter weather advisory is up for the mountains due to the expected blowing and drifting. Temps today will start in the 20’s for most but will fall throughout the day with subzero readings making it all the way to the coast by tomorrow morning.
A slow warmup is in store for this week culminating in some rain showers and a shot at 50 degrees on Thursday.
Today will feature mainly cloudy skies and warmer temps as an Arctic front approaches the area. Another storm is passing to our south and could bring a few flakes to the midcoast region. Highs today will be mild by comparison to recent days reaching the 30’s region-wide. It won’t last long however as the Arctic front will bring another blast of bitter air for tomorrow along with, you guessed it, more wind. This round of wind will not be anything like the one we saw earlier this week but it will still drop the wind chills down to levels that will be far from comfortable.
No significant storm threats are in sight as of now.
More clouds are on tap for today as a storm brushes by to our south. Precipitation associated with the storm will impact southern New England where a coating to 2″ of snow is expected. North of Portsmouth, no precip is expected and a cold and cloudy day is anticipated. Temps this morning are extremely chilly with some subzero readings in the mountains and single digits making it all the way to the coast. Temps will however warm up quite nicely into the upper 20’s north and low to mid 30’s south.
No significant storms are on the horizon as of now.
Today will feature conditions similar to yesterday with one exception: much less wind. That being said, winds will still be busy this morning but will relax this afternoon as high pressure moves in. Skies will once again be sunny and temps will once again be chilly with highs ranging from around 15 in the mountains to around freezing at the coast. Despite the continued cold, it will feel much warmer today as winds die down and the wind chill becomes less of a factor.
No significant weather events are in the forecast for the forseeable future.
While Astronomical Spring is just 2 days away, it sure will feel like winter out there today. Winds have been up out of the northwest all night with many areas gusting over 40 MPH. Winds will continue at that force throughout the day today as cold air continues to push in. Highs today will also be brutally cold as temps struggle into the single digits in the mountains and 10’s inland. The coast gets lucky here as downsloping warms them up into the mid to upper 20’s.

Wind chills will also be a factor this morning as bitterly cold temps combine with strong winds. Bundle up if heading outside today!
Today will feature rain or snow showers depending on your location as an Arctic front pushes through the area. Expect snow showers turning to rain showers along the coast and in the foothills while the mountains stay snowy. The front itself will push through late this morning and behind it NW winds will begin to blast the region full force as more cold air moves in. An area of low pressure will develop to our SE along the front and intensify as it moves towards Atlantic Canada. Eastern areas will see some light snow out of this however the main impact will be the strong winds that will continue through tomorrow.
As for temps, today will be a warm one ahead of the front with coastal and inland areas rising into the 40’s and the mountains making it all the way into the low 30’s. Behind the front, temps will tumble into the 10’s and single digits tonight with a strong wind making it feel much colder. Wind chill values will likely dip into the 20 below range in the mountains while the coast sees wind chills in the single digits below zero tomorrow morning. Welcome back to winter!
Today will feature beautiful weather region wide as NW winds help the coast and foothills warm into the 40’s under full sun. The mountains will see a mix of sun and clouds though the trend even there should be on the sunnier side as low level moisture is severely limited. We will see a few high clouds by afternoon though as our next frontal system moves in. As for temps in the mountains, low to mid 30’s are expected.
Tomorrow looks to be a nice day as well ahead of our next front though Wednesday looks to be a bit cooler. No significant storms are in sight.
Our storm is moving out this morning and most of the accumulations are done with the exception of NE areas where heavy snow bands will continue for another few hours. For the rest of us, some dry air at around 10,000 feet is causing precip to shut off and thus most of southern Maine is now dry.
That’s not to say precip is completely done, the upper low is only just beginning the process of moving through the area and everyone will likely see another round of snow this afternoon as it finishes its crossing.

Here is the HRRR model showing one more round of snow this afternoon before the storm moves out for good. Expect these snow showers/squalls to be heaviest between 1 and 6 PM this evening before moving out around 8 or 9 PM tonight.
Temps will be falling today starting in the 30’s this morning and crashing through the 20’s this evening. The mountains will likely see readings in the 10’s while the coast likely stays in the 20’s.
Precip is already falling across much of the area as our next storm moves in. Expect snow to flip quickly to freezing rain/rain along the coast but remain all snow inland this evening. Currently, some weak divergence aloft is causing a heavy snow band to move through Cumberland County on its way NE.

This divergence is causing a brief heavy snow burst which, despite warm temps, is accumulating on some of the roads so use caution if you happen to be driving this afternoon.

Warmer air will continue to flood into coastal regions this afternoon though after looking at data from a special sounding (vertical profile of the atmosphere) from the NWS in Gray, models appear to have had a warm bias with this event and thus a tad more frozen precip is expected especially away from the immediate coast.

Here is the HRRR model’s take on what the first phase of our storm will look like through the wee hours of tomorrow morning. This model does a good job showing the rain/snow line advancing this evening with heavy snow across the interior and rain across coastal areas. I would advise taking this model with a grain of salt however as it shoots the rain line past Lewiston. When accounting for the warm bias of the models for this event, the rain line should approach the Lewiston area but is not likely to pass it especially considering the snowpack we still have on the ground.

The second phase of the storm occurs tomorrow when a strong upper low crosses the area. Expect temps to crash tonight as NW winds behind a developing secondary low move cold air into the region. As a result, tomorrow’s part of the storm will be an mostly snow event which is where the coast picks up their accumulation. There is still some debate as to if/when/where an inverted trough might setup to help focus the precip so uncertainty still remains. Precip looks to move out tomorrow evening from west to east.
Here is the latest snowfall forecast showing the coast escaping with little more than a dusting while the mountains see the jackpot with 8-12″. Due to warmer temps, this will be a wet and heavy snow so watch for a few isolated power outages as trees sag under the weight of the snow.
