Area Forecast Discussion National Weather Service Gray ME 421 PM EST Sat Feb 27 2021
SYNOPSIS. Precipitation will come to end this evening as low pressure moves into the Canadian Maritimes. A weak system will cross the area tomorrow night with snow and rain showers. We will see very mild temperatures on Monday before an Arctic cold front passes through the area in the late afternoon or evening. Temperatures on Tuesday will top out in the teens and 20s along with gusty winds. Broad high pressure over the eastern U.S. beyond Tuesday should keep our region mostly dry with seasonable temperatures through Friday.
NEAR TERM /UNTIL 6 AM SUNDAY MORNING/. Precipitation will diminish over the next several hours from southwest to northeast across the region. Most areas that have not yet switched to rain will likely see snow end as a brief wintry mix.
Patchy fog looks likely across much of the region, with some areas of dense fog after the precipitation ends this evening. Any fog will linger until stronger mixing occurs after the passage of the cold front late this evening and shortly after midnight. Temperatures will be lingering around freezing across interior areas before the mixing occurs, so areas of black ice are also likely to accompany the fog in many locations.
With the frontal boundary expected to clear the region shortly after midnight, a west-northwesterly breeze should prevent temperatures from falling too far tonight, with lows mainly in the 20s expected.
SHORT TERM /6 AM SUNDAY MORNING THROUGH 6 PM SUNDAY/. A nice mild day is expected on Sun. Despite shallow mixing temps should make it into the 40s for most areas S of the mtns. It will be an in between period . as precip is not really likely until Sun evening.
LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/. Overview . The extended remains a rollercoaster temp-wise. Despite the wild swings in temps there is not a strong signal for a large QPF event in the next week.
Impacts . Main concerns will revolve around strong cold front Mon night/Tue. This will feature a return to deep winter-like temps . strong wind gusts around 35 mph . and the potential for snow squalls along the cold front.
Forecast Details . A weak front will lift thru the area Sun night into Mon. The best forcing for ascent will be with the S/WV trof tracking thru Quebec . and offshore with convection. I still think there will be lots of rain/snow showers around so I am continuing the trend of a high PoP/low QPF forecast. Overall I do not anticipate significant impacts from this system . though a brief period of mixing may occur in the mtns.
Deeper mixing behind that front on Mon though will result in an even milder day. The MHT-ASH corridor may make a run at 50 degrees. While this will likely lead to quite a bit of melting of snow and ice . I do not expect this fairly routine spring- like warmth to cause significant issues on that front.
Mon night a tropopause polar vortex is forecast to blast thru New England. This feature is currently positioned in far Nrn Northwest Territories on the edge of the Beaufort Sea. These features of often associated with Arctic outbreaks and given this origin I anticipate this will be no different. High temps Tue will be at least 20 degrees colder than Mon. Strong wind gusts will accompany the cold . approaching 35 mph at times during the day As winds start to kick up late Mon. wind chills may approach 20 below in the mtns. There will also be some potential for snow squalls on the leading edge of the TPV . though model placement of that is still to be determined. For now I think the most likely part of the forecast area to see the core of the TPV and thus strongest forcing will be Srn NH. I have increased PoP to chance there to highlight the snow showers over the rest of the forecast area. There will also likely be a sustained period of upslope snow showers in the wake of the cold front . and I have increased PoP to high likely/low categorical given the dry model bias of snows after frontal passages.
Beyond Tue ensemble guidance is in fair agreement for near to above normal temps and below normal chances of significant QPF.
AVIATION /20Z SATURDAY THROUGH THURSDAY/. Short Term . Snow and rain will bring intervals of IFR and MVFR conditions through this evening. Patchy fog will also reduce visibilities this evening, bringing LIFR conditions at times. Drier air will begin to push in from the NW and northern locations may lift to MVFR by morning. After sunrise the rest of the area will follow suit.
Long Term . A weak front will cross the area Sun. While a period of fairly widespread SHRA or SHSN will cross the area . it is low confidence in how likely it will be for any one terminal to experience precip I have higher confidence inland. away from most TAF sites . so I am not entirely confident in widespread IFR conditions just yet. A stronger front crosses the area Mon night into Tue. There may be some +SHSN along the front itself but timing and coverage is to be determined. There is a much higher likelihood of widespread NW wind gusts approaching 30 kt Tue. MVFR CIGs and local IFR in SHSN will transition to the mtns around HIE behind the cold front.
MARINE. Short Term . Low pressure will continue to affect the waters through this evening. Southern winds with a good fetch off the open Gulf of Maine may allow for gale force winds along the Midcoast into this evening where gale warnings remain in effect. Elsewhere, winds may gust to 30 knots where SCAs remain in effect through tonight. The exception will be Casco Bay where SCAs are only for this afternoon. Patchy fog expected this afternoon into this evening prior to the wind shift to the west. Winds and seas subside Sunday.
Long Term . SCA conditions may linger with a weak frontal passage Sun night into Mon. Of bigger concern will be a strong . Arctic front that crosses the waters Mon night into Tue Gale force wind gusts. heavy snow showers . and freezing spray will all be possible thru Tue. Winds and seas will gradually diminish into Wed.
