Area Forecast Discussion National Weather Service Gray ME 938 AM EST Sun Jan 19 2020

SYNOPSIS. Low pressure exits into the maritimes today with some lingering clouds and snow showers, mainly across the higher terrain. Cold high pressure will then gradually build in for the first part of the week. Warmer weather looks likely mid to late week.

NEAR TERM /UNTIL 6 PM THIS EVENING/.

935 AM . For this ESTF update I made minor adjustments to near term grids to reflect colder mesonet values as well as satellite and radar trends.

Prev disc . 720 AM . At this point see very little in the way of addl accumulations, with only some light snow left across the ern zones, and this should end withing the hour, and some SHSN in the mtns, which are now transitioning to upslope type showers. So, all the WSWs will be dropped.

Previously . Secondary sfc low taking shape near KBOS and then will be sliding east toward the Bay of Fundy by midday. For the most part snow has ended or will end across all but nrn NH, the ME mtns and our ern zones by 12Z, with some lingering snow in these areas thru the morning. All precip associated with these system should be done by midday, but upslope SHSN will be possible in the mtns this afternoon. There's a bit of a trailing trough which will keep some clouds in place thru the morning, but some breaks of sun are expected this afternoon, moreso later in the day as the flow shifts and picks up from the NW. Highs will range from the low to mid 20s in the mtns to the mid upper 30s on the coast and in srn NH.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM MONDAY/. Sfc gradient will tighten overnight, as the low winds up over the maritimes, and sfc high approaches from the W, so N-NW wind s continue overnight with clearing skies outside of the mtns, where the upslope will continue to produce clouds and SHSN. CAA will persist thru the night and lows will drop to zero to 5 above in the mtns and 10-15 in the south.

Not much changes on Monday although the gradient will weaken some during the afternoon, but it should be mainly sunny with highs in the teens N, to the low to mid 20s in the S.

LONG TERM /MONDAY NIGHT THROUGH SATURDAY/. Monday night will be cold, calm, and clear. Because of this have pushed temperatures towards and slightly below the colder MEX in the northern valleys as fresh snow cover should further enhance the cooling. Expect some locations to reach the mid teens below zero with 20 below not out of the question if we can keep skies perfectly clear. Have continued the colder trend but will hold off on going too much colder in deference to the potential for just a few thin clouds to hold on.

Tuesday cooler temperatures aloft push into the region keeping daytime highs in the 20s south and teens north.

In a shift from last night, while temps aloft remain coldest on Tuesday, now seeing hints of a shortwave moving through late Tuesday. The result is a warmer trend for Tuesday night as increasing cloud cover prevents radiational cooling. Have trended the cloud cover up as well as temperatures and PoP, although it remains at a slight chance.

The warming trend continues through the end of the week as a ridge moves eastward across the CONUS. The dry spell continues with high pressure remaining firmly in place. The next chance for precipitation will be on the weekend when another storm will bring snow to the region.

AVIATION /15Z SUNDAY THROUGH THURSDAY/. Short Term . Will see gradual improvement this morning with all terminals improving to VFR by midday. VFR will persist thru Monday.

Long Term . VFR conditions will continue throughout the week with no chance of precipitation over the next 5 days. A few clouds may move through the mountains on Wednesday but still expect conditions to remain above VFR.

MARINE. Short Term . Although the S-SW flow will slacken a bit today, N-NW winds pick up late today and overnight, and will reach gusts of 15 kt or so overnight.

Long Term . High pressure builds in for the start of the week followed by a gradual warming trend as and upper level ridge returns warm air to the region. No precipitation is expected through the weekdays and winds and seas will remain below SCA for most of the week.

GYX WATCHES/WARNINGS/ADVISORIES. ME . None. NH . None. MARINE . Small Craft Advisory until 11 AM EST Monday for ANZ150-152-154.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
