Area Forecast Discussion National Weather Service Caribou ME 613 PM EST Mon Mar 1 2021

SYNOPSIS. A strong cold front will cross the area this evening. Cold high pressure will build in from the west Tuesday into Wednesday while strong low pressure remains across the Maritimes. Another cold front will cross the region Thursday. High pressure will build toward the area Friday into the weekend.

NEAR TERM /THROUGH TUESDAY/. 6:12 PM Update: A cold front will rapidly sweep east across the FA early this evening. The front will usher in a sharply colder air mass tonight with increasing wind. So far, the shower activity along and behind the front has been fairly tame. It is still possible that some stronger streamers develop a little later this evening once the northwest flow becomes established. The main concerns overnight will be for low wind chills, snow showers and possible squalls, and across mainly northern and central Aroostook County for the development of blowing and drifting snow. Made some adjustments for this evening based mostly on the latest observations and radar trends.

Previous discussion: The triple point of the low has made its way to the east dragging the majority of the precip with it. Per radar, areas around the far north and the west currently have little to no precip, while the southern and eastern region is still seeing light snow and rain. Snow accumulations have remained to the north with 2 to 5 inches in those areas. Temperatures have remained rather level throughout the day as the triple point low swings through. As the evening progresses, the arctic cold front will swing into the state, bringing cold temperatures and the possibility of snow squalls. Dynamic models show elevated CAPE and lapse rates, as well as surface convergence and negative theta-E. The greatest threat for snow squalls are across the northern areas, but could possibly reach to the Downeast and Bangor Region. Recent model runs show as the triple point low quickly exits over the maritimes tonight, the low will intensify, tightening the pressure gradients and switching the winds from the WNW. The temperature will begin to fall this evening into teens along the coast and negatives in the north as the arctic cold front settles in. The tightening gradients will cause the WNW wind to increase drastically throughout tonight, causing blowing snow in the north for the newest accumulations. Wind advisories have been issued for the entire region starting early morning Tuesday into Tuesday night.

Tuesday is shaping up to be one of the harshest days this winter. A cold upper low evident on water vapor satellite pictures across central Ontario is expected to cross Maine early Tuesday morning. The low is expected to rapidly move out across the Maritimes and to southern Newfoundland by Tuesday evening. An intense surface low in the Saint Lawrence Seaway will combine with high pressure building to the south of the area to produce a very tight pressure gradient across the area. The air mass will be about as cold as we have seen this winter with temperatures likely to not get out of the single digits in the Saint John Valley with teens Downeast.

The combination of the strong pressure gradient/cold air advection, higher sun angle/steep low level lapse rates will mean a harsh wind of 20 to 35 mph with gusts to 50 mph, and perhaps even 55 mph across the higher terrain. The combination of the wind and low temperatures makes wind chills a concern, especially in the morning. Often there is some difficulty in reaching warning level criteria wind chills due usually to a lack of wind in a deep arctic air mass. In this case, the wind is not going to be lacking and the eventual wind chills will be more a function of the actual air temperatures.

SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/. The entire period will be dominated by the cold vertically stacked low over the Canadian Maritimes. The large scale low will slowly drift towards Labrador during the period. Winds continue to be the biggest item for Tuesday night, but the trend will be down and advisories will expire during the evening and most of the blowing snow issues should be winding down in the evening. There is a bit of warm advection as a weakening clipper system approaches from Ontario. The clipper will rapidly weaken as it enters the region, but will still generate cloudiness later Tuesday night into Wednesday for southern zones. The airmass will moderate for Wednesday as high temperatures will be some 10 to 15 degrees warmer on Wednesday than Tuesday, but still well below normal. Winds will still gust as high as 30 mph Wednesday morning and produce wind chills below zero in northern zones. For Wednesday night into Thursday, a shortwave will rotate around the big low in the Maritimes. This will cause increasing clouds from the north and a reinforcing batch of cold air as highs will be about 5F colder. Snow showers will become increasing likely in northern and western zones Thursday afternoon with the increasing moisture and weak lift, but no accumulations. Wind gusts will again hit the 30 to 35 mph mark and wind chills will be below zero in northern zones for much of the morning.

LONG TERM /THURSDAY NIGHT THROUGH MONDAY/. The large closed upper low over Labrador continues to be the weather maker as it's blocked in place. The below normal temperatures and windy conditions will largely continue through the weekend with moderating temperatures after Sunday as the low finally fills and moves out. No precipitation beyond scattered snow showers can be expected during the period. That includes a chance of snow squalls in northern zones Thursday night as another shortwave rotates around the upper low. The NW flow will continue to produce a lot of cu/stratocu fields except in downslope areas. Temperatures will slowly moderate from well below normal readings to near normal by Monday. The best chance of the week for radiational cooling won't occur until Sunday night when surface high pressure finally builds over the region.

AVIATION /00Z TUESDAY THROUGH SATURDAY/. NEAR TERM: A strong cold front will cross the region through the evening. Across northern areas expect MVFR/IFR, occasional LIFR, conditions early tonight with snow showers. MVFR, occasional IFR, late tonight with scattered snow showers and blowing snow. Across Downeast areas expect VFR/MVFR, occasional IFR, early tonight with scattered rain/snow showers. VFR Downeast overnight. VFR/MVFR, occasional IFR, across the north and mountains Tuesday with scattered snow showers and areas of blowing snow. VFR Downeast Tuesday. West/northwest wind 10 to 15 knots with gusts up to 20 knots early tonight, increasing to 15 to 25 knots with gusts up to 35 knots late. Northwest wind 20 to 30 knots, with gusts up to 40 to 45 knots Tuesday. Northwest low level wind shear across the entire region early tonight then again Tuesday.

SHORT TERM: Predominately VFR with NW winds gusting over 30kt at times. Tempo IFR in snow showers north of HUL and GNR Thursday afternoon into Friday.

MARINE. NEAR TERM: Storm warnings begin at 7PM tonight until 7PM Tuesday. Wind gusts up to 55 kt and seas 7-10 ft. Heavy freezing warnings run from 5AM to 11AM Tuesday.

SHORT TERM: Gale conditions with freezing spray are forecast Tuesday night into early Wednesday morning. A Small Craft Advisory will then be needed continuously from Wednesday into Saturday night.
