Area Forecast Discussion National Weather Service Gray ME 911 AM EST Fri Jan 24 2020

SYNOPSIS. Strengthening high pressure centered to the north provides a cooler northeasterly breeze and fair weather today. Low pressure will approach from the west Saturday and cross the region Saturday night with heavy precipitation possible. Much of next week should feature fair weather.

NEAR TERM /UNTIL 6 PM THIS EVENING/.

910 AM . At 13z a 1038 millibar high was centered over Quebec province. A weak cold front extended from the international border through northern Maine For today. the weak boundary will continue to press southward with little in the way of sensible weather as surface high continues to build by to our north. Much of the area will continue to see filtered sunshine through high and patchy mid cloud. GOES visible imagery shows a burgeoning area of low clouds south of Casco Bay in northeast flow. Based on current trends and latest HREF I expect low clouds to move onshore south of Casco Bay during the afternoon. For this ESTF update . I made minor adjustments to near term grids to reflect latest satellite trends as well as the 13z mesonet.

Prev Disc . 635 AM Update . Main updates at this point are for temperatures this morning; cool temperatures realized in sheltered valleys across the north and west will gradually rebound and pull in line with other sites later this morning.

Previously . Today, surface high pressure remains in control while upper level ridging extending from the eastern Caribbean up into the northeast CONUS starts to erode. This comes in response to an approaching low, presently cutting off from the northern stream over the Mississippi Valley, moving eastward into the Ohio Valley today. High clouds associated with this system will continue to stream in overhead with warming and moistening SW flow aloft. Meanwhile at the surface, strong Canadian high pressure shifting into the Maritimes induces a northeasterly breeze with week cold advection into western and central Maine. Eventually low level onshore flow develops across southern zones which will increase cloud cover there this afternoon and evening. High temperatures today range from the low/mid- 30s over higher terrain up into the low- 40s across southern NH and southwest Maine.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/. Heights aloft fall precipitously and surface high pressure shifts east, away from the area during the short term as a broad cut-off trough moves up the Ohio Valley. Moistening onshore flow strengthens through the low- and mid-levels which will lead to drizzle/freezing drizzle and fog development over the coastal plain and easterly/southeasterly upslope areas late tonight into tomorrow morning. Temperatures stay steady for the most part, in the 20s for most and near freezing over southeast New Hampshire and coastal Maine.

The column gradually moistens during the afternoon, transitioning patchy drizzle to a brief period of freezing rain and rain showers, and eventually rain and snow showers. Meanwhile increasing surface winds scour out fog. Greatest risk for glaze development presently exists over higher elevations of southern New Hampshire, but without confidence in coverage or impacts to issue any headline for now.

LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/. A short wave trough will approach from the west on Saturday. This will aid in inducing a strong southeasterly low level jet which will in turn aid in a relatively short-lived but heavy band of precipitation crossing the forecast area from south to north Saturday night. Any given location may only experience steady/heavy precipitation for around 6 hours (aside from drizzle) as the fast-moving ribbon of enhanced forcing for ascent moves through. However, precipitation amounts should average around an inch area-wide. In addition, low level forcing via a coastal front should allow for enhanced precipitation amounts on the coastal plain, pushing those values up toward 1.5 inches.

The main issue continues to be temperatures in the column across the far interior. The NAM continues to be the warmest by far, with the result being a good amount of freezing rain for the mountains. Most other members of the 00z guidance suite are far less warm aloft which portends more toward snow and sleet in the mountains. Either way, the coastal plain and southern zones south of the mountains will be mostly rain. Have gone with a consensus of thermal profiles at this time which allows for a forecast of snow/sleet/freezing rain in the mountains with sub- warning amounts expected for each element. We should be able to pin down more specific precipitation types by location in the next forecast cycle. On the coastal plain and across southern NH zones, we'll have to watch out for the short period of heavy rain which may cause localized flooding of small streams, roadways, and other low lying areas, especially where snow is currently blocking storm drains.

With a strong low level inversion in place, the vast majority of the strong low level jet winds are expected to remain well above the SFC. However, we'll have to watch the immediate coast where there is a chance at a brief warm sector.

The system will quickly move out by 12z Sunday, relegating this system to a 12 hour or less event for us for the most part. Snow showers are likely, at least for the mountains on Sunday as the upper low moves though. Could be some additional accums there. Thereafter, fair weather looks to be the case for the beginning of next week.

AVIATION /14Z FRIDAY THROUGH TUESDAY/. Short Term /Through Saturday/ . VFR this morning for all sites. MVFR ceilings develop along the southern coast this afternoon, spreading inland and along the Maine coast this evening. IFR or worse may develop in fog and drizzle/freezing drizzle tonight over southern New Hampshire and the coastal plain of Maine. Over the mountain sites of LEB and HIE, ceiling restrictions are more likely to hold off until the evening and overnight. Tomorrow, drizzle transitions to -shra and -shsn, perhaps a brief period of -fzra with restrictions likely to continue.

Long Term . IFR to LIFR conditions expected in rain and drizzle on the coastal plain and central/southern NH locations Saturday night. Mixed precipitation expected farther north and west. LLWS a good bet all terminals Saturday night with strong low level jet moving overhead. VFR conditions return Sunday.

MARINE. Short Term /Through Saturday/ . Smooth sailing in forecast today with a northeasterly breeze as high pressure strengthens to the north over Canada. Easterly winds increase tonight into tomorrow with increasing fog, drizzle, and eventually rain chances. SCA wind and waves likely develop tomorrow afternoon, before strengthening further in the long term.

Long Term . A gale watch has been posted for Saturday night as strong southeasterlies are expected ahead of a strong cold front. Still lower confidence on how strong they will be as an inversion will be in place, but gusts around 35 kt seems like a good bet at this time outside of the bays.

GYX WATCHES/WARNINGS/ADVISORIES. ME . None. NH . None. MARINE . Gale Watch from Saturday evening through Sunday morning for ANZ150>154.
