Hello everyone!

A calm day is in store for the region today as low pressure drifts even farther off to our east and high pressure drifts slightly closer from the west. Light NW winds will keep the mountains the cloudiest and the coast the sunniest today, though even in southern areas some clouds will work in this afternoon as a very weak disturbance passes by overhead. Little if any in the way of precip is expected except perhaps for a flurry or two in the mountains. Temps will be seasonably cool, ranging from the upper 20’s in the north to the mid 30’s in the south.

Hello everyone!

While not quite as snowy as yesterday, today will still remain on the cooler/cloudier side of things as low pressure spins well to our east. Look for mostly cloudy skies outside of southeastern NH, with snow showers impacting the northeastern part of the region from Sugarloaf Mountain down towards Penobscot Bay. Snow will dry up as it tries to push towards Bath-Lewiston-Bethel, with little if any flakes expected there. Accumulations for those that do see snow will fall in the dusting-1″ range. High temps today will range from 30 in the north to 40 in the south.

Hello everyone!

The circulation aloft that brought us yesterday’s storm hasn’t made it very far since it impacted us, and is currently meandering over the mountains of Vermont. This will keep us on the cooler side with unsettled conditions, especially in the mountains. High temps will range from 30 in the north to 45 in the south. Cloud cover will range from overcast in the mountains to intermittent sunshine along the coast.

In terms of precipitation, snow will be ongoing today in the mountains, and will actually ramp up this afternoon as northwesterly flow taps into some upsloping dynamics. An additional 4-8″ can be expected today in the higher terrain, especially NW facing slopes. If you’re at all able to sneak out there with your powder skis, do it!!

Hello everyone!

The major winter storm that moved into the area last night will continue today as low pressure moves from Boston towards Portland. The impacts from this storm will vary considerably over short distances. Here’s a quick look region by region.

At the coast (east of the Turnpike), temps are now above freezing with rain falling. In these areas, concerns today will include localized street flooding from heavy rainfall, strong ENE winds (especially along the Midcoast), and coastal flooding (especially south of Portland). High temps will range from the mid 30’s near I-95 to the mid 40’s near Camden.

Inland, snow is falling this morning with some areas reporting mixed precipitation types, mostly sleet. Several inches of snow are already on the ground, with several more on the way for those closer to the mountains. Accumulation gradients will be extremely tight with this system near the Sebago Lake-Lewiston area. Concerns here will include slick roads, and power outages from heavy wet snow weighing down trees and power lines.

In this mountains, this one’s all snow. Over a foot is expected in the higher terrain and the consistency will be much drier/fluffier than the foothills. Wax up your powder skis, and get out there! Be careful if driving around, as snow covered roads will remain a problem through most of the week as snow continues to fall.

Hello everyone!

Today will feature mainly cloudy skies and at least a few hours of dry weather this morning before our next storm moves in this evening. The primary concern this morning will be locally dense fog which will reduce visibilities for the morning commute. Some of this fog is occurring in inland areas where the temperature is below freezing, so watch out for potential slick spots as well. Fog will gradually lift later this morning.

By the early afternoon hours, rain and snow will be developing in New Hampshire ahead of our next storm system. Snow will initially be confined to the higher terrain, with snow levels lowering after dark tonight. Coastal rain and mountain/inland snow will arrive in Maine during the evening hours.

The storm will really get cranking overnight with heavy rain along the coast and heavy snow inland. Winds will also pick up, especially along the coast heading into tomorrow. Snow totals will range from around 18″ in the mountains to dustings at the coast. I’ll have more details on this system either tonight in a special update or in tomorrow morning’s post.

Hello everyone!

Today’s primary feature will be warmer temps as the core of the arctic air mass moves off to our east. Look for initially chilly temps this morning to give way to mild temps by this afternoon, ranging from 35 in the north to 40 in the south. Skies will start off on the clearer side this morning but clouds will increase in coverage this afternoon as our next storm system approaches from the west. That system will bring light mixed precip to the mountains and light rain to coastal areas tomorrow.

Hello everyone!

Today (Friday) will bring calm but chilly weather as Arctic high pressure crests overhead. Look for high temps to moderate a bit from Thanksgiving’s record cold, ranging from the mid 10’s in the north to the mid 20’s in the south. Additionally, with high pressure overhead, winds will slacken considerably compared to Thursday’s NW gusts. Generally sunny skies are expected region-wide with no precipitation to worry about.

Hello everyone, and happy thanksgiving!

Today will feature our first taste of true arctic air as strong high pressure descends towards the region from northern Canada. Expect high temps ranging from around 5 above in the north to 15-20 along the coast. NW winds gusting 30-40mph will bring wind chills into subzero territory for all but the immediate shorelines. Mountain snow flurries will continue in upslope flow while the rest of the region sees downsloping sunshine.

Interestingly, since records began in Portland in the late 1800’s, no November day has ever failed to reach 20 degrees, which means today’s airmass is one of a select few that we can truly deem “historic” without exaggeration. Record low-high temps (“mini-max’s” according to NWS lingo) are forecast through much of New England today, so it’s not just a local fluke here at the Jetport. Chances are you’d have to go back to around or perhaps even before the Civil War era to find an airmass in New England as cold as this one in November. Pretty neat stuff!

All that to say, bundle up if you’re headed outside, and enjoy a lovely (hot!) turkey dinner!

Hello everyone!

Today (Wednesday) will feature the arrival of our first Arctic airmass of the 2018-2019 winter season! Snow squalls will act as the vanguard for the incoming chill, bringing low visibility, slick roads, and a quick coating-1″ of snow. Not everyone will see a squall, but more will than won’t based on the latest data. The timing for squalls will be early/mid afternoon in the mountains and late afternoon/early evening closer to the coast. Gusty NW winds are expected behind the front with quickly falling temps. Therefore, high temps will occur on the earlier side, ranging from a little above 20 in the north to a little above 30 in the south.

Hello everyone!

Today (Tuesday) will feature the arrival of another snow event as a weak area of low pressure tries to get going offshore. Expect snow to be falling by daybreak, picking up in intensity as we head towards the midday hours. The steadiest and heaviest snow will fall along the coastal plain where a general 3-6″ is expected. Lighter amounts will be found NW of the Sebago Lakes region, more along the lines of 1-3″. The northern mountains will see little more than flurries as the bulk of the moisture associated with this system clings to the coast.

Temperatures will range from the mid 20’s in the north to the mid 30’s along the typical immediate coastal warm spots, where a brief mix with rain may hold amounts down a little bit.
