Today will feature cool temps and calm weather as Canadian high pressure drifts overhead once again. Expect some sunshine this morning especially in northern/eastern areas before clouds move into the area on the north side of another ocean storm developing near North Carolina. That storm will pass far enough to our south that precipitation is not expected, but we will see a period of overcast skies this afternoon. Temps will remain on the cooler side today due to the clouds and gentle northerly breezes between the high to our north and low to our south. Just about everyone should top out within a few degrees of 40 (a little above near Augusta and a little below in the mountains/western NH).
Last night’s storm came in about as expected, though some spots got a bit more snow than expected. The system responsible for producing the snow is now cruising towards Nova Scotia and as a result, any leftover flurries will quickly taper off. Winds will turn northwesterly as the low departs, though the absence of a strong area of high pressure behind the system means that gusts likely won’t exceed 20 mph. As with any northwest flow situation, the coast will be first to clear out this morning. Abundant sunshine will push temps to around 50 especially along the coast of Maine. Much more snow fell down in southern NH so high temps there may be limited to the mid/upper 40s. The mountains will be the coolest under persistent overcast in the upper 30s.
Today will feature cool temps and cloudy skies as our next storm system begins to approach from the southwest. Precipitation from this system will arrive in southwestern NH around noon in the form of light snow. Yesterday’s Canadian high pressure has dug in over Nova Scotia this morning and will be providing a constant drip of cool dry air throughout the day. As a result, most snowflakes will be evaporating before they hit the ground during the early afternoon hours.
That will change later in the afternoon as a coastal storm begins to intensify off the North Carolina coast. Bands of steady snow will move into southern NH by 4-5 PM and will become heavy shortly after that. Most spots in western Maine can expect steady snow by 6-7 PM with heavy snow arriving in southern areas by 8-9 PM. While this storm will start off as an all-snow event, areas east of I-95 south of Portland and south of route 1 east of Brunswick (the “immediate coastline”) may mix with or change over to rain later tonight.
Snow will continue through the overnight hours before tapering off early tomorrow morning.
Snow totals will range from around 1″ along the coast and in far northern parts of the mountains to around 10″ in interior southern NH. The greatest forecast uncertainty is, as usual, near the rain/snow line right along the coast. It’s also unclear exactly how far northeast the heavy banding needed to produce >6″ totals will extend.
Either way, the snow that does accumulate will be very heavy and wet due to warm temps right around 31-33F. Be ready for some tough shovelling and some power outages especially where >6″ accumulates. That’s usually a good benchmark for picking out spots where tree limbs will start to break under the weight of the snow. Nicer weather returns tomorrow before another system approaches later in the week.
Today will feature beautiful early spring weather across the region as a strong area of Canadian high pressure drifts across Northern New England. Expect clear skies area-wide except perhaps for a few cirrus across southwestern NH this evening. Because this airmass has arrived from Canada, temps today will be on the cooler side of what we’d expect this time of year. Highs will range from 25 in the north to 40 in southern NH. Today will be a great day to head outside and enjoy some much-needed fresh air. Remember that going outside for a walk/hike is a perfectly acceptable social distancing activity so long as you keep your distance (>6ft) from others.
Today will feature cool temps, clear skies, and gusty NW winds as Canadian air arrives behind yesterday’s cold front. High temps will range from 25 in the mountains to 45 in southeastern NH. If you head outside, it will feel considerably chillier due to gusty NW winds. We may see a few spots gust to 40 mph today but most of us should remain in the 30-40 mph range. That’s low enough to avoid widespread power outages, though a few branches may come down on lines this afternoon. A few leftover high clouds along the coastline will depart over the next couple hours which will leave sunny skies for all but the highest summits.
Today will feature the arrival of warm air as a storm system cruises up the Saint Lawrence Valley and pushes a cold front in our direction. Ahead of that front, southwesterly breezes will be responsible for pushing warm air in our direction. This time of year, southwesterly winds are actually fairly cool for the Midcoast (east of Brunswick) because the Gulf of Maine is still fairly chilly. Similarly, some residual snowpack and the usual terrain features will conspire to keep cooler air locked in across the usual mountain/interior foothill spots. Both of these areas will are high temps in the upper 40s to low 50s today. Along the coastal plain of Maine, temps will be a bit warmer ranging from the mid/upper 50s near Augusta to around 60 in Portland to the upper 60s in interior York County. The warmest air will be reserved for southern NH where temps will soar above 70 today including right at the seacoast. A quick glance at satellite imagery shows just about no chance for sunshine anywhere in the region today as the clear skies associated with the system’s warm sector (behind the warm front and ahead of the cold front which is where we’ll be today) look to remain south of New York City.
As the cold front approaches this afternoon/evening, we’ll have to start thinking about the chance for showers and thunderstorms. A line of storms will form in New York early this afternoon before moving quickly east. They should arrive in western NH around 4-5 PM and may be strong enough to produce a damaging wind gust or two in the southwestern part of the state. Storms will weaken as they move east, and by the time they arrive in Maine around 6-7PM, they may not even be strong enough to produce thunder. Showers and storms will continue fading as they move offshore tonight.
A weak storm is passing offshore to our south this morning, but it’s having some trouble moving smoothly into the Atlantic as it runs into a strong area of high pressure over Nova Scotia. As a result, we’ll be stuck with cool east/northeast flow, overcast skies, and plenty of drizzle/light rain. The steadiest rain will be found over southern parts of the area this morning. Some of that precipitation is falling as some light snow over the hills of Central NH but even there, only a coating-2″ of accumulation is expected. Mostly this is a rain event. High temps will remain surprisingly uniform across the area this afternoon, ranging from 35 in the mountains to a little above 40 along the coastal plain. Our next chance at some sunshine won’t come until Saturday as another warm storm system cruises through the region tomorrow.
