A cold front is on the way this morning. Out ahead of this boundary, we’re seeing mild temps and somewhat unsettled conditions across the area. Radar and ground observations show light snow in progress across the mountains and some of the foothills north of Lewiston over towards Waterville. These snow showers may drop a dusting or possibly even an inch where they persist for the longest. That, as per usual, will be up in the mountains especially on any slopes facing west. Temps today will be driven by the usual upslope/downslope pattern we’d expect from westerly flow. Look for highs in the mid 20s up north and low 40s down south. Most spots will see mostly cloudy skies for most of today with the best shot at some sunshine being down along the coast early this morning and later this afternoon. Westerly breezes will be noticeable (15-25 mph) but well below the threshold of any power outage concerns.
Today will feature the departure of the storm we saw being high winds, heavy rain, and mountain snow yesterday. As the storm heads up into Canada, we’ll see westerly winds pick up and set the usual upslope/downslope pattern. Expect snow to continue in the mountains for the first half of today with an additional inch or so in the valleys and several inches up on the summits. Snow may fall heavily at times even into the foothills as cool air moving into the region aloft faster than at the surface sets up a favorable environment for snow showers and squalls.
Breaks of sun combined with the effects of downsloping will keep temps relatively mild along the coastal plain today, ranging from the upper 30s to low/mid 40s. Low clouds and upslope flow will have the opposite effect in the mountains where high temps will range from the upper 20s to lower 30s.
Westerly breezes may gust above 30mph at times which could be enough for some scattered outages but no major or widespread issues are expected.
The storm I talked a bit about yesterday is on our doorstep this morning.
Surface observations across the area show moderate to heavy rain advancing north from the Boston area into Maine and New Hampshire. Temps across the area are just a bit too warm for snow outside the higher terrain. As precip increases in coverage and intensity this morning, temps will drop a bit especially up north, but snow is still likely to be mostly a higher elevation affair today. Also worth noting is that several thunderstorms have been observed down in Boston this morning. Some rumbles definitely aren’t out of the question as these cells move into our area over the next few hours.
Rain and snow will continue to move in this morning and will become heavy by the time lunch approaches.
The peak of the storm will be in the early to mid afternoon as the storm center moves from Cape Cod towards Portland. During this time, rain will be heaviest along the coast, snow will fall at rates of 1-3″ per hour up above 2,500 feet or so, thunder will be possible especially south of Portland, and winds will peak along the coast.
Here’s a quick look at expected snowfall accumulations with the major caveat that totals will be heavily dependent on elevation. If you’re above 2,000 feet or so, take the over on these numbers. If you’re in the valleys, take the under. The jackpot still looks to be about 18-24″ for the higher summits in the Whites and possibly the top of Saddleback/Sugarloaf too. This is going to be heavy wet snow, but that’s exactly what we want right now to set a solid base for future powder skiing.
Wind gusts along the coast are likely to peak around 35-45 mph with a few 50-55 mph gusts possible northeast of Portland. This is definitely enough to produce some outage concerns, especially in the spots that tend to go dark first.
Rain and snow will taper off this evening except in the mountains where upslope snows will continue through the night and into tomorrow with several inches of additional accumulation.
High temps today will range from the mid 30s up north to the mid 40s in the south.
After a long stretch of extreme tranquility here in northern New England, Mother Nature is ready to rumble once again. A powerful Great Plains blizzard will tap into moisture from the Gulf of Mexico as it heads east tomorrow, setting up a nice heavy precipitation event for our area.
Before we get to enjoy that storm, quiet weather will be the rule again today. Low clouds are noted on satellite imagery across much of the mountains and foothills while some sunnier breaks are seen closer to the coast. As the day goes on, mid/high clouds will advance from the southwest and low clouds will move in off the ocean so the whole region should end up overcast by sunset (except perhaps for far northeastern areas near Waterville). High temps will range from the low 30s up in the mountains to the low/mid 40s in southern NH.
Precipitation will arrive from southwest to northeast tomorrow morning. Initially, precip will likely fall as freezing rain up north and a mix of rain/snow/sleet closer to the coast. As the storm gets closer, the mountains will change over to snow and the coast will change over to rain with the foothills becoming the battleground for rain/snow/sleet. By the time the heaviest precip starts moving out, rain should be the dominant precip type outside of the mountains with snow hanging on in the higher terrain.
This map gives a pretty good idea of where to expect snow, sleet, ice, and rain. Focus less on the numbers and more on the general footprint of each precipitation type. The highest snowfall totals will be on the higher summits with more modest accumulations in the valleys and northwestern foothills. Most of the foothills will see sleet, which could mix in over the mountains too. Any ice accretion should be fairly light and confined to the mountains during the onset of the event. Down along the coast, this one is all rain.
What do accumulations look like? I didn’t have time to pull together a map myself this morning so I’ll pass along what our friends up at the NWS in Gray have put together.
The jackpot 12″+ totals will be up above 4,000 feet in the Whites and near the summit of Sugarloaf. Most of the rest of the mountains above say 2,500 feet will get 8-12″ with the valleys picking up around 3-6″. Amounts will taper off quickly as you head down into the foothills, though the mix of snow, sleet, and rain will produce icy roads.
Behind the storm on Sunday, snow will continue in the mountains while the rest of us dry out on gusty west-northwesterly winds.
Our quiet weather pattern continues today as another weak disturbance slides off to our south. This will keep clouds in the mix area-wide today with a few flurries possible this morning in southern NH and this afternoon/evening in the mountains. High temps will range from the low 30s up north to the mid 40s in southeastern NH.
Our next storm arrives on Saturday with heavy rain for most and snow in the higher terrain.
Today will feature continued quiet weather as another weak disturbances floats overhead. That disturbance, much like the last few we’ve dealt with this week, will be strong enough to bring clouds and maybe a few mountain flurries/snow showers but nothing more. The best chance of some sun will be found in southern NH today. High temps will range from around 30 in the north to around 40 in southeastern NH.
Our quiet weather pattern continues to roll along today as weak disturbances pass overhead but fail to produce much in the way of meaningful impacts. This morning’s disturbance has ensured mostly cloudy skies region-wide and has been producing a few snow showers up in the mountains and in the foothills near/west of Augusta. While dustings are possible especially in the higher terrain before this system moves out in the next couple hours, little/no impacts are expected.
In the wake of this system, light NW flow will result in some clearing downwind of the mountains this afternoon. The sunniest spots will be over in southern NH while parts of the Maine coast may hang on to some more clouds. High temps will range from the low 30s up north to the high 30s in southern NH. Clouds will thicken back up this evening ahead of our next weak disturbance which seems likely to bring snow showers back to parts of the mountains tonight.
A weak disturbance aloft is headed our direction this morning which means that sunshine currently observed over eastern parts of the area will be short-lived. Clouds moving in from the west will keep high temps a bit lower today than they were yesterday, ranging from just below 30 in the north to around 35 in the south. A few flurries may reach the ground up in the mountains late this afternoon into this evening but little to no accumulation is expected.
Today will feature continued quiet weather as the prevailing storm track remains shifted off to our south. We narrowly missed one ocean storm last night and are slated to narrowly miss another in a couple days. North of these storms, we’re left with mostly dry and clear conditions though there is no Arctic air in sight. So today will be another day of partly to mostly sunny skies, light NW breezes, and temps a little on the warm side of normal. Look for highs ranging from around 30 up north to around 40 in SE NH.
Another quiet day of weather is expected today as our pesky ocean storm sends one last disturbance in our direction. This system, in the form of an upper-level low dropping south from Quebec, appears not to have enough moisture to produce much if any precipitation though it will result in some increased clouds this afternoon. Look for mostly sunny skies along the coast and foothills this morning while upslope clouds remain locked against the higher summits. As the afternoon goes on, those clouds should dissipate before being replaced by low/mid level clouds associated with this upper-level low. High temps today will range from the mid/upper 20s up north to the mid 30s along the coastal plain.
Peering into the extended outlook, our next couple chances at snowstorms appear to miss wide right as various upper-level disturbances just couldn’t get into the right place at the right time. This should leave our region experiencing mostly quiet weather for the next week to ten days before another pattern shakeup could produce conditions more favorable for snow.
