Cloudy And Damp Today

Hello everyone!

We’ll have more traditional Maine spring weather today as a weak coastal storm moves up the coast. Morning fog and low clouds near the coast will be slow to burn off, while the mountains will start the day off with a mix of sun and clouds. Any sunshine this morning will be obscured by the time we get to the midday hours as that developing storm gets closer. Precipitation will overspread the area from the southeast later in the afternoon, arriving on the coast between 3 and 5 PM before moving inland. Rain could be heavy at times especially near the coast.

Rain is unlikely to reach the mountains until much later tonight as the ability of the system to throw moisture northwestward wanes. Highs today will be seasonably mild, ranging from 45 along the coast to 55 in the mountains to 65 in between.

More Unsettled Weather Today

Hello everyone!

Today will feature more in the way of unsettled weather as a slow-moving storm system remains stationed to our west. The biggest impact from this system today will be cloud cover. Even areas that see little to no rain will see overcast skies persist after morning dense fog lifts. As for rain, any that falls today will be of the light and showery variety. Everyone is at risk for some showers, but the best chance for any steadier rain will exist along the midcoast, closer to the plume of deep tropical moisture.

In spite of the clouds, we’ll remain relatively warm today with highs ranging from 45 along the immediate coast to 50 in the northern mountains to 65 for areas in between.

One more dreary day is on tap for tomorrow before we move towards nicer weather.

Mild And Unsettled Today

Hello everyone!

Today will feature mild and unsettled weather as plenty of warm moist air flows north out of the Gulf of Mexico, but arrives here without a way to consistently turn into rain. The best mechanism for getting this moisture out of the air is a strong frontal boundary currently extending from the Northern CT Valley up through the Northern Maine mountains. North of this is where the most consistent rain will be falling today.

For areas to the south, there are some showers ongoing at the coast this morning but we’ll need to wait for the remnants of last night’s Mid Atlantic thunderstorms to arrive before we get any steady or heavy rain. That should arrive in Southern NH around 10 AM, with places near Portland holding off until 11 AM-12 PM. That rain will be heavy at times and could contain an embedded rumble of thunder. It will last until the early/mid afternoon, at which point the steady rain will once again be confined to areas north of the front.

Temperatures will be heavily influenced by the aforementioned frontal boundary. North of it, look for highs in the mid 40’s. South of it (away from the immediate coast), high temps will rise into the mid to upper 60’s, with some parts of NH making another run at 70. The midcoast and other coastal areas will once again be cooler, in the low to mid 50’s.

Warmer Air Arrives Today Ahead Of Wet Storm System

Hello everyone!

Warm air is being delayed in moving into the region, but will make substantially more progress today than it did yesterday. Currently we have a sharp frontal boundary located over southern NH, with Keene reading in at 55 and Manchester only 46. Meanwhile, Boston is already at 67! This warm and humid airmass will make slow northward progress today, but as we all know there are numerous ways that promised warmth never comes to fruition this time of year.

The first applies to the coast. Any onshore component to the wind and we cut dozens of degrees off the high temp. For coastal areas northeast of Portland, there will be a stout onshore component to today’s winds, meaning highs stay stuck in the upper 40’s to low 50’s.

The second applies to the foothills and northern mountains. When you add undulations to the terrain, and a little leftover snowpack, it’s just hard to get rid of the cold air. I think we end up doing it outside of the mountains north of Route two only because there’s a moderately strong low pressure system to our north over the St Lawrence valley instead of the high pressure system we usually rely on to “dam” the cold air against the higher terrain. So the mountains will remain around 50 degrees, but most of the foothills especially south of Route two should get into the warmer airmass with highs in the low to mid 60’s.

For those areas in the interior coastal plain that can access the full potential of today’s warmth, your forecast today is looking pretty lovely. Morning clouds and fog should burn off to at least some afternoon sunshine as highs soar into the upper 60’s to low 70’s. Some parts of interior southern NH could even get up into the 75 degree range!

For the entire area, clouds will increase this afternoon as the system to our west slowly closes in. Rain should hold off until around sunset in NH and far northwestern parts of Maine, and will spread slowly south and east after dark. The bulk of the rain arrives tomorrow, and there will be plenty to go around.

Unsettled Again Today

Hello everyone!

A warm and moist airmass is on our doorstep this morning. Here in Ithaca, we’re enjoying a 25 mph sustained southerly wind with temps already in the mid 50’s. Unfortunately warm air is notorious for struggling to get very far north in New England this time of year, so today will be a “transition day” of sorts with the warmth trying and largely failing to make it into the region at the surface. Aloft, it will be a much different story. Without terrain influences, warm air will pour into the region from the south/southwest. That will support widespread cloud cover (if it’s not cloudy already in your area, it will be soon) as well as some showers.

Precip is falling over NH as I write this a little before 8:30 AM, and Maine is next in line over the coming hours. Most of this is falling as rain, but I’ve seen some reports of light sleet out of MA so don’t be surprise if a few of your raindrops are a little icier than usual. The showers won’t bring any impacts of consequence, and will be slow to depart the region early this afternoon.

High temps will range from 35 in the north to 45 or 50 in far Southern NH.

Clear And Seasonably Warm Today

Hello everyone!

Today will feature clear skies and seasonable temps as high pressure slides overhead. Look for highs ranging from 45 in the north to 55 in the south with decreasing winds and clearing skies. There’s not much else to say about today’s weather except get out and enjoy it to whatever extent you can!

Much rainier weather will move in for the weekend.

Breezy Conditions Usher In More Sunshine Today

Hello everyone!

There are lots of clouds out there this morning, especially in the mountains where snow showers are showing up on radar. Thankfully, the storm system responsible for these clouds will be moving off to the northeast today, and strong NW breezes will be the main contributor to today’s weather. Expect NW gusts generally in the 40-45 mph range today, with higher values as you go up in elevation in the mountains.

The NW flow will set up our favorite upslope/downslope pattern, so as soon as the large scale clouds from the low itself clear out in the next few hours, it’s looking sunnier for the coast and foothills. The mountains will keep the clouds and non-accumulating flurries through the rest of the day. Highs will range from 35 in the mountains to 55 in Southern NH.
