Area Forecast Discussion National Weather Service Gray ME 300 AM EST Sun Mar 7 2021

SYNOPSIS. Cool and fair weather today as high pressure builds in from the west. A warming trend will start Monday into the second half of the week. Much of the week will be precipitation free with the exception of isolated snow showers Monday night and rain showers towards the end of the week as a front approaches.

NEAR TERM /THROUGH TONIGHT/. Quiet weather is expected today as high pressure builds in from the west. Aloft, we will be under a deep trough that extends down to the Bahamas, so another cool day is expected with highs ranging from the low to mid 20s north to lows 30s south. Northwest flow will continue today, but winds will be relatively light. Upslope flow will allow for clouds to linger in the mountains with mostly sunny skies elsewhere.

Skies will be mostly clear tonight with light winds allowing for efficient cooling. Lows will range from the single digits north to teens south.

SHORT TERM /MONDAY/. High pressure will settle to our south Monday allowing for winds to turn more westerly. Mostly sunny skies and the high March sun angle will allow for afternoon temperatures climb into the upper 30s south to upper 20s north.

LONG TERM /MONDAY NIGHT THROUGH SATURDAY/. Overview . Gradual warming expected thru the week . likely peaking on Thu. Uncertainty grows beyond that as model guidance battles between warming temps and lingering winter cold . though a return to closer to normal temps looks likely.

Impacts . Very little in the way of wx impacts anticipated thru the week. A multi-day stretch of above normal temps for the latter half of the week will likely result in average temps in the upper 30s and lower 40s for parts of the area. This may be enough to get ice moving on some of the rivers . especially in parts of Srn NH.

Forecast Details . Passing S/WV trof will knock the building ridge back a bit on Tue. This will mostly delay but not deny the warm up. Still expecting temps to climb into the 40s anyway. Not much in the way of precip anticipated with this feature . though a stray shower cannot be ruled out.

NAEFS guidance is forecasting H8 temps around +4C building into the region late Wed and especially Thu. Mixed down that would mean widespread 60s . however forecast soundings indicate that we will struggle to fully realize this. That is not all that surprising this time of year. 925 mb temps would have much of the area in the 40s and 50s Wed . coolest across interior Wrn ME. By Thu 925 mb temps are pushing +10C across Srn NH and this is far more supportive of temps in the low 60s. There is pretty strong ensemble consensus that this will be the warmest day.

Uncertainty grows quite a bit after that as models push a trailing cold front towards the area. Just how fast it pushes thru will drive Fri temps . which could still be quite mild if it delays until the afternoon. Given that upper support for ascent will be more focused N thru Quebec . chances for showers is also low confidence. Whether the front comes thru dry or not temps do look to return closer to normal for the weekend.

AVIATION /08Z SUNDAY THROUGH THURSDAY/. Short Term . VFR prevails through Monday with relatively light NW winds today shifting to westerly Monday afternoon.

Long Term . Widespread VFR conditions expected thru the late work week. A passing cold front Tue may lead to a localized SHRA/SHSN but chances are low for any one terminal.

MARINE. Short Term . NW winds over the waters will shift to the west by Monday afternoon as high pressure settles to the south with gusts generally less than 20 kts. Light freezing spray is possible this morning and again Monday morning.

Long Term . Persistent SW flow will develop over the waters and continue thru the end of the week. While the WAA over cold waters tend to not efficiently mix down there is still some potential for marginal SCA wind gusts. The persistent nature of the flow direction will also allow seas to build in excess of 5 ft.

GYX WATCHES/WARNINGS/ADVISORIES. ME . None. NH . None. MARINE . None.
