Area Forecast Discussion National Weather Service Gray ME 559 AM EST Sat Jan 23 2021

SYNOPSIS. High pressure over the Great Lakes will keep a cold northwest flow over New England today. Expect below normal temperatures and gusty winds which will finally begin to die down on Sunday. High pressure noses its way into New England through the week as a few waves track by to the south. Although these will bring a chance of wintry weather to southern New England, they will largely be a miss for New Hampshire and Maine. Expect dry conditions to continue with seasonably cool temperatures.

NEAR TERM /UNTIL 6 PM THIS EVENING/. 6am update: Have increased PoP and SnowAmt through southern NH as the snow showers continue to persist. Very light and fluffy snow has resulted in up to an inch of accumulation overnight in a narrow band near Manchester.

Impacts: Breezy Northwesterly flow through the day. High pressure is centered over Iowa with low pressure over Newfoundland creating a robust pressure gradient over the region. This will result in increasing northwesterly flow through the day today pulling a cold canadian airmass into the region. The result will be highs in the teens north to mid 20s south, which is below normal. A few snow showers through southern New Hampshire and off shore are the remains of yesterdays front, however the cold northwesterly flow will continue through the start of the weekend.

For precipitation have slightly enhanced the very low pops through the mountains where the upslope flow favors a few snow flurries as a short wave moves through this afternoon but the overall dry nature of the airmass will keep most areas dry.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SUNDAY/. Impacts: Breezy winds will continue, with dangerous windchills across the north. Mountains will see very strong winds with gusts exceeding 100mph early Sunday morning.

Overnight the cold air will remain as does the steady northwesterly winds driving wind chills down to around 20 below along the Canadian border. The steady wind will keep things well mixed and the result is not much spread in the temperature guidance for tonight with both valleys and ridges alike dropping down. Expect right around 0 in the north with single digits pushing close to the coast.

The balance of winds and cold temperatures will bring frigid windchill and have issued a Wind Chill Advisory for northern Coos, northern Oxford, and northern Franklin. Further east, central Somerset maybe needed as well although they are slightly less windy so will hold off for this update cycle.

Saturday night and into Sunday morning will be breezy at the surface but the temperature profile should shield all but the summits from very strong winds. A low level jet, around 3000ft will peak just over 50kts early Sunday morning. With low level temperatures strongly inverted the majority of this wind will not reach the surface. Still, some gusts to around 30kts are possible, especially along the immediate coastline where the low level jet is strongest and surface inversion is weaker.

Where the winds will really show is at elevation. With a low level jet at 3000ft and Mt. Washington exceeding 6000ft that wind will be funneled up and over the Whites. Furthermore, an additional jet streak aloft exceeding 100kts at 25kft will also be able to mix down as the backside of the cold air as the low moves east. at 12Z Sunday, the 1.5 PVU tropopause drops to around 500mb. This double squeeze play of a low level jet going up and over the mountains at the same time as an tropopause jet drops lower will results in winds easily exceeding 100mph through the higher summits. MOSguidance for KMWN shows 95kts sustained and have kept that value with gusts to 120kts in the forecast. In fact higher values - gusts exceeding 150mph /130 kts/ for MWN are possible early Sunday morning. While MWN will be the strongest winds, all the peaks extending from the whites through, the Mahoosucs, and up towards the Carrabassett valley have the potential to approach 100mph gusts on Sunday morning.

Sunday will see similar temperatures to Saturday with highs again only reaching the mid 20s in the south however winds will begin to subside with wind chill decreasing.

LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/. The storm track stays south of us all week which will leave us dry for the most part. Although we will be on the cold side, it won't be unusually cold for this time of year. High pressure gradually builds east out of the Great Lakes for the first part of the week, with the northwest winds gradually diminishing as the high approaches. A couple of waves track to our south and may bring wintry precipitation to southern New England, but at this point it seems unlikely that these will affect New Hampshire and Maine with anything other than some cloud cover. Temperatures through the week will be mostly near normal for highs, and near to above normal for lows due to either winds or clouds preventing good nighttime cooling most nights. It's not until the second of the two waves pass to our south that we get a solid area of high pressure moving in from the west along with clearing skies. Thus our colder low temperatures will probably hold off until the end of the week.

AVIATION /12Z SATURDAY THROUGH WEDNESDAY/. Short Term . A few very light snow showers are impacting MHT for the next few hours, however most SHSN will decrease through the day. Northwesterly flow will continue through the day with gusts to 30kts along the coast. Those winds will subside slightly overnight but remain around 15-20kts. Low level jet at 3kft of 50+kts will pass over on Sunday morning, and may result in wind shear for a few hours as it moves through.

Long Term . Mostly VFR conditions expected as high pressure builds in from the west. Northwest winds gradually weaken each day. A couple of waves pass to the south of New England and could bring some cloud cover to New Hampshire and Maine, although anything lower than MVFR ceilings seems unlikely at this point.

MARINE. Short Term . Cold northwesterly flow will move over the waters. Expect the cold air to accelerate with the warmer ocean helping to mix gusts to 40kts across the eastern waters. A Gale Warning remains in effect. Additionally the cold temperatures and strong winds will result in freezing spray and a freezing spray advisory has been issued for all coastal waters. Winds will finally diminish on Sunday.

Long Term . Winds continue to diminish as high pressure approaches from the west. A couple of lows pass by to the south of New England this week, although significant impacts in the Gulf of Maine appear unlikely. The second of the two lows may be the stronger of the two, and depending on its track it could cause some stronger northeast winds in the Gulf of Maine late in the week.

GYX WATCHES/WARNINGS/ADVISORIES. ME . Wind Chill Advisory from 9 PM this evening to 9 AM EST Sunday for MEZ007-008. NH . Wind Chill Advisory from 9 PM this evening to 9 AM EST Sunday for NHZ001. MARINE . Small Craft Advisory until 4 PM EST Sunday for ANZ153. Freezing Spray Advisory from 9 PM this evening to 9 AM EST Sunday for ANZ150>154. Gale Warning from 2 PM this afternoon to noon EST Sunday for ANZ150>152-154.
