Area Forecast Discussion National Weather Service Gray ME 747 PM EST Sun Feb 28 2021
SYNOPSIS. A weak system will cross the region tonight with snow and rain showers. Mild temperatures will be felt on Monday before an Arctic cold front passes through the area in the late afternoon and early evening. Bitter wind chills will follow the front tomorrow night. Temperatures on Tuesday will top out in the teens and 20s along with gusty winds. Canadian high pressure will nose into New England for the latter half of the week.
NEAR TERM /UNTIL 6 AM MONDAY MORNING/. 740 PM . Pushed back arrival of precip by an hour or two in most places, generally within a couple hours either side of midnight. Thinking it will start at snow or a mix of snow in the mtns, with maybe a coating in the mountain valleys before a complete switch to rain, and a few inches above about 2000 ft. Once precip begins, temps should stay steady or slowly rise through daybreak, when they will rise more quickly. Otherwise forecast remains in good shape.
Previously . Clouds will continue to advance into the region through this evening, with showers advancing into southern New Hampshire and western Maine during the evening hours, and reaching farther north and east after midnight. The precipitation will be more showery in nature through the evening, then become steadier after midnight. Any accumulating snowfall looks to remain across the higher terrain and far northern areas, with some isolated pockets of freezing rain in these same areas.
SHORT TERM /6 AM MONDAY MORNING THROUGH 6 PM MONDAY/. The precipitation will lessen in coverage through the morning, with some scattered shower activity through the afternoon hours. High temperatures will be mainly in 40s tomorrow before an arctic frontal boundary crosses the region tomorrow evening and into the early overnight hours. Some stronger snow showers or snow squalls are likely to accompany the frontal passage, and be most widespread in coverage across the mountains. Temperatures will then crash tomorrow night behind the front, with temperatures falling below zero across the north, and near 10 along the coastline. Gusty winds will also accompany the cold, making for very cold wind chill values overnight tomorrow night and into the morning on Tuesday. A wind chill watch is being issued to account for this across northern zones for tomorrow night and Tuesday morning, where minimum wind chills of colder than -30 degrees are possible.
LONG TERM /MONDAY NIGHT THROUGH SUNDAY/. Overview . Bitterly cold to start the period with gradually improvement thru the remainder of the week. Forecast has trended more towards upper low and colder temps than previously anticipated . but little in the way of significant QPF.
Impacts . Greatest impacts will be on Tue. A myriad of hazards are expected . some on the waters covered below . and some over land. Main concern will be the combination of cold and wind leading to bitterly cold wind chills. In the mtns these may fall to dangerously cold levels and a wind chill watch is in effect. Additionally the wind themselves will be quite gusty. I expect gusts in excess of 40 mph at times . but the frozen ground and lack of leaves on the trees should mitigate widespread impacts at this time.
Forecast Details . Tue will feature the strongest CAA. Despite the deep mixing temps will still top out in the teens and 20s. calendar day highs will likely occur around midnight . but during the day it will be brutally cold. For the first part of the day Tue wind chills everywhere will remain at or below zero. Weakening CAA and cloud cover moving in will keep temps warmer Tue night than they will be Mon night.
The deep mixing will also tap some strong winds aloft. It will be quite gusty during the day . with forecasts right around 40 mph. I have not issued a wind advisory at this time for several reason. As mentioned above the frozen ground and lack of leaves should mitigate widespread impacts . but also we have at least a couple rounds of model guidance to look at for trends before we need to issue one. I have highlighted the wind threat in the HWO and DSS products. May see some very high wind gusts in the mtns . where inversion near summit level will help to accelerate winds. MWN forecast is around 150 mph currently.
Beyond Tue the forecast has trended towards upper low staying near the forecast area. This cold air mass will be recycled and move back thru Quebec and work back towards New England. It remains to be seen whether the core of the moderated cold goes W of the forecast are or not . but I have trended our extended range temps colder.
AVIATION /01Z MONDAY THROUGH FRIDAY/. Short Term . Ceilings continue to lower to IFR conditions tonight as a weak system approaches the region. Some light snow across the north and rain south will continue overnight into Monday with conditions improving to VFR late in the day Monday. Winds will become gusty from the west to northwest towards evening. Some snow showers may briefly reduce visibilities, especially across northern areas, tomorrow evening. Gusty winds will continue through Tuesday morning.
Long Term . Generally expecting VFR to prevail after the frontal passage. There may be some lingering MVFR CIGs N of the mtns along with local IFR in SHSN as upper low stays nearby. Otherwise the main concern will be strong wind gusts Tue . in excess of 35 kt at times.
MARINE. Short Term . Southerly winds will develop tonight with a few gusts to 25 knots out of the south and seas building to 3 to 5 feet. An Arctic front will cross the waters Monday, switching winds to the west. Strong west-northwesterly winds to gale force, and possibly to storm force, will impact the waters beginning tomorrow night.
Long Term . Storm watches are in effect . with gale watch in Casco Bay . for strong wind gusts developing early Tue. Bitter cold and winds will combine for the potential of heavy freezing spray over the coastal waters N of Cape Elizabeth into midday Tue. Winds and seas will gradually diminish into Wed.
