Area Forecast Discussion National Weather Service Gray ME 1159 AM EST Sun Jan 17 2021

SYNOPSIS. Low pressure will gradually exit through the Canadian Maritimes today, but upper level low pressure will continue to provide for accumulating snow showers to the mountains. A weak system crosses the region on Monday with another weak system passing through on Tuesday night and Wednesday.

NEAR TERM /TODAY/. 1200 PM Update . Extended the Winter Weather Advisory for all but central Somerset to account for travel impacts through the afternoon. Lapse rates will remain favorable for autoconvective snow showers with a trough axis/PV anomaly dropping down from Canada offering additional forcing for locally intense snowfall. This is in-line with the reasoning for the initial product which is mainly for highway travel through the notches and valleys toward the north.

1015 AM Update . Not too many changes to the forecast with this update except to tweak temperatures/dew points according to latest trends Winds gusts are picking up on time. with frequent gusts in the 25-30 kt range along the coast and more in the 15-25 kt range further inland. Not seeing upsloping showers reaching the ground on the downwind side of the mountains, but as intensity picks up over the next couple hours some light snow/flurries may reach into the foothills through the well- mixed and dry low-levels. Will monitor upstream webcam trends to see if the Winter Weather Advisory over the north needs to be extended by a couple hours.

650 AM Update . Upslope snow machine going to town up in the mountains at this hour based on observations and webcam imagery. The advisories remain unchanged. Little in the way of forecast adjustments at this time. The forecast remains on track.

Previously .

Upper level low pressure will continue to pivot northeastward across our forecast area this morning. As of 07z radar returns have increased fairly markedly across central and northern zones with light rain at lower levels and snow at higher elevations. Mountain snows will continue through this morning, with prime west-facing slopes picking up another 3 to 6 inches of snow today. Will drop the expiring winter storm warning with this package update but hoist a winter weather advisory for the mountains through noon today. Lower elevations will see little in the way of accums, but notches and higher elevations will see periods of heavy snow this morning, with occasional 1/4 mile S+ expected. Mountain roads will be very slippery.

Otherwise, downwind of the mountains, some flurries and sprinkles are expected along with varying amounts of clouds today. Temperatures outside of the mountains should be well above normal today, with downsloping winds aiding temperatures to rise up to the mid 40s.

Winds will be gusty as well, with frequent gusts around 30 MPH likely.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM MONDAY/. A weak short wave trough passes across the forecast area tonight into Monday. Therefore, clouds will be prevalent along with scattered snow showers in the mountains. Conditions should improve Monday afternoon with the passage of the short wave trough. Highs Monday will be well above normal once again with the absence of arctic air continuing.

LONG TERM /MONDAY NIGHT THROUGH SATURDAY/. Several fast moving shortwaves will race across the northern tier of the eastern CONUS primarily bringing periods of more clouds than sun. There will be low chances for snow showers with these passing disturbances but opportunities for accumulating will be limited through next week. Temperatures will oscillate either side of normal with each passing wave with Wednesday night looking to be the coldest as high pressure briefly crests over the area.

We will be between passing shortwaves Tuesday with partly cloudy skies and temperatures ranging from the teen north to low 30s south. The next short wave crosses Tuesday night into Wednesday for an increase in cloud cover and low chances for a snow shower. High pressure crosses the area Wednesday night allowing for more optimal radiational cooling leading to lows dropping below zero in the north and lows in the single digits to near 10 degrees south. The next set of short waves cross the area Thursday into Friday night with better chances for widespread snow shower activity although accumulations look to be limited to where snow showers are more persistent in the mountains.

AVIATION /18Z SUNDAY THROUGH FRIDAY/. Short Term . MVFR to IFR conditions will continue in the mountains today in snow showers. Downwind of the mountains, we expect VFR conditions with a few areas of MVFR cigs from time to time. Any fog will dissipate early this morning. Westerly wind gusts of 25 to 30 kts are expected today and will diminish tonight. Areas of MVFR cigs are expected late tonight and Monday morning as a weak disturbance moves through.

Long Term . Mainly VFR through next week. Fast moving disturbances may bring periods of MVFR in lower cigs and -SHSN Tuesday night into Wednesday and again Thursday into Friday.

MARINE. Short Term . An offshore gale returns this morning as low pressure gradually moves away from the forecast area. All marine zones except Casco bay continue with the gale warning through about midnight. Winds and seas will then diminish late tonight and Monday but remain at SCA thresholds.

Long Term . SCA conditions likely Monday night will diminish Tuesday. Another round of SCA conditions Wednesday as NW winds pick up behind a passing disturbance with SCA conditions subsiding by Thursday morning.

GYX WATCHES/WARNINGS/ADVISORIES. ME . Winter Weather Advisory until 4 PM EST this afternoon for MEZ007-008. NH . Winter Weather Advisory until 4 PM EST this afternoon for NHZ001>003. MARINE . Small Craft Advisory until 1 AM EST Monday for ANZ153. Gale Warning until 1 AM EST Monday for ANZ150>152-154.
