Area Forecast Discussion National Weather Service Gray ME 931 AM EST Mon Mar 8 2021

SYNOPSIS. The long talked about warming trend will begin today and continue through the end of the week. While temperatures will reach the mid to upper 30s today, by Thursday many locations will push 60 degrees. In addition much of the week will be free of precipitation. The one period to watch will be late tonight as a weak front will bring isolated to scattered snow showers.

NEAR TERM /THROUGH TONIGHT/. 930am Update . Only minor changes to temperatures to account for the latest observational trends. Clear and sunny skies will continue through the afternoon.

Update . Minor changes to reflect latest observational trends.

Previous discussion . Slowly but surely we are starting the warming trend . and that will really begin today. Mixing is still forecast to be rather shallow beneath high pressure . but increasing temps aloft will support widespread mid to upper 30s. Despite coolish temps for this time of year the increasing sun angle should make it feel warmer than it actually is.

SHORT TERM /TUESDAY/. A weak S/WV trof will cross the area late tonight. There is very little moisture to work with so at this time I have mostly scattered snow showers in the forecast . and concentrated most of those in the higher terrain. The cloud cover will prevent temps from getting too cold . and may in fact see them start rising after midnight as clouds become thicker.

Primarily this S/WV just delays the real warmth from moving into the local area by a day. H8 and 925 mb temps are supportive of afternoon highs in the mid to upper 40s and possibly the lower 50s across Srn NH however . so above normal is very much still expected.

LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/. Surface high pressure crosses the region Tuesday night, so we'll see a clear sky, light winds, and efficient cooling conditions. This will put temperatures in the 20s for most overnight, with teens in the northern valleys. But as the high moves east we will find ourselves on the warmer side of it with a deep southwest flow bringing top down warming to the Northeast US. Expect temperatures to warm into the 50s on Wednesday for much of New Hampshire, although more of an onshore component to the low level winds will keep things a bit cooler in Maine. Even warmer air arrives for Thursday with temperatures likely reaching or exceeding 60 degrees for the southern half of New Hampshire and far western Maine. Although we do still have a snow cover in most of the area, it's a very old and crusty one as the last significant snowfall was back in February. With top down warming expected, I see no reason to think that we won't see a solid warm up despite the snow cover. In fact we should be whittling away at that over the course of the week. Still, though, the coast of Maine may keep an onshore flow and stay a bit cooler. Even here, though, it will be above normal.

A cold front moves through the region on Friday with a significantly colder air mass behind it. The shortwave trough will pass primarily to our north, with the bulk of the precipitation also staying to our north as well. However, we could see a few showers as the front passes. We are not looking at a significant rain event here, just some passing showers at best. Temperatures will still be warm Friday especially ahead of the front. In fact, as winds shift to the northwest behind the front we will see better mixing and less marine influence on the coast of Maine. Thus I expect the warmest day for the Maine coast to actually be on Friday when the coast will push 60 degrees. Meanwhile to the north cold advection will begin to be felt with some cooler temperatures.

Even colder air moves in for the weekend with temperatures falling back below normal and even well below normal by Sunday. Raw model guidance suggests highs well below freezing for the entire area on Sunday, thus I departed from the NBM guidance for this period in favor of the colder models. In addition to the colder air, stronger mixing in the cold advection will lead to stronger winds as well. I favored the raw and MOS guidance for winds as NBM was too low.

AVIATION /15Z MONDAY THROUGH FRIDAY/. Short Term . Widespread VFR anticipated today. Passing S/WV trof tonight may lead to some stray SHSN across the area with local IFR conditions possible. However confidence at any one given terminal is very low and thus not in the TAFs at this time. In the wake of the passing wave MVFR CIGs will likely develop on the windward side of the mtns and around HIE.

Long Term . VFR conditions expected as high pressure slides across the area and then sets up a warm but dry southwest flow for much of the week. A cold front on Friday will provide the best chance of showers and MVFR conditions at times, with winds shifting to the northwest and strengthening into the weekend.

MARINE. Short Term . High pressure in control of the waters today and tonight. Behind a weak frontal boundary Tue NW winds will freshen. There may be a few 25 kt wind gusts well outside of the bays but at this time a SCA is not anticipated.

Long Term . High pressure crests over the Gulf of Maine on Wednesday with a southwest flow developing as it shifts to the east. Winds in the southwest flow could eventually approach advisory levels, although the warm wind over cold water suggests that surface level winds may be lower than model guidance suggests. A cold front comes through on Friday shifting winds to the northwest. With colder air moving in through the weekend stronger winds are possible.
