Area Forecast Discussion National Weather Service Gray ME 737 PM EST Fri Jan 24 2020

SYNOPSIS. High pressure will build by to our north tonight into Saturday. An onshore flow will bring clouds and the chance for some spotty drizzle or freezing drizzle overnight. 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 AM SATURDAY MORNING/. 730 PM . For the overnight, did some tweaking to the DZ forecast, and pushed it closer to the ESE upslope areas and also held it off until closer to daybreak. Will have to watch for some patchy areas of FZDZ in this area, but, could be just some very light SN as well /snizzle, if you will/. Despite the onshore flow aloft, fairly deep boundary lyr of NE flow which always introduces more dry air than expected, which will affect both the timing and the possibility of ice crystals in the cloud, even if they are very small. I did carry this trend into Sat morning, but thinking that there will be enough mixing by afternoon to break up the DZ, and will have to deal with the approaching precip developing at higher levels in the atmosphere.

At 19z a 1038 millibar high was centered over eastern Quebec province. GOES imagery showed extensive high and patchy mid clouds across the area. The onshore flow was also producing some low clouds that had begun to work onshore along the coastal plain For tonight. low clouds will continue to spread inland across southern and coastal sections Elsewhere. mainly high and some patchy mid clouds for the balance of the night. We may see some spotty drizzle and freezing drizzle towards morning in southern and coastal sections. Otherwise a dry night with lows in the 20s and lower 30s.

SHORT TERM /6 AM SATURDAY MORNING THROUGH SUNDAY/. On Saturday . onshore flow increases between the high over the maritimes and the frontal system approaching from the mid Atlantic region. We'll see some spotty drizzle or light freezing drizzle through early afternoon before steadier precipitation arrives over southern and western New Hampshire by late afternoon in the form of rain. highs Saturday mainly in the 30s with a few lower 40s over southeast New Hampshire and along the immediate coast. On Saturday night steady precipitation quickly overspreads the remainder of the area in advance of 60 knot low level jet and becomes heavy at times. It looks like a 6 hour window of moderate to heavy precipitation along and ahead of this jet. Winds near the coast may gust close to 40 mph for a brief period as heavy rain mixes some stronger winds down at times. Temperatures will be steady or slowly rise ahead of the occluded front and surface low before dropping off following its passage Concerning p-type we'll see a mix of sleet. light freezing rain and wet snow across the mountains and foothills with rain elsewhere along with a period of freezing rain and sleet for some interior sections away from the coast. We're likely to need winter weather advisories for the mountains and foothills from Saturday evening into Sunday morning for the mixed. Much of southern New Hampshire as well as coastal areas should see rain heavy at times with some localized urban and poor drainage issues possible. In between these two areas . it'll depend largely on surface temperatures being above freezing when the steadier precipitation develops towards Saturday evening. Steadier precipitation will quickly taper from southwest to northeast Saturday night with passage of the occluded front and coastal low On Sunday. colder air begins to wrap back into the area behind the surface low with cooling column changing lingering precipitation across the higher terrain back to snow.

LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/. The upper level low associated with the weekend storm system will gradually pass through New England on Monday. The instability from this low, combined with upslope winds, will likely keep snow showers ongoing across the Mountains into Monday night. Some snow showers are also possible outside of the mountains as the low moves eastward into the Canadian Maritimes Monday evening.

Even after the upper level low moves away from our region, broad troughing will linger across the southern part of the country during the midweek, and will gradually weaken by late in the week. During this same time period, anomalously strong ridging will persist across central and northern Canada. The ridge will more or less remain centered over the Hudson Bay region through the end of next week.

The result for temperatures from this pattern is that anomalous warmth will continue across much of Canada, while below normal temps will cool even further through late in the week across the Mid- Atlantic and southern states. New England will be in the middle of these two regimes, with temperatures remaining fairly close to normal next week after cooling off with the departure of the upper level low Monday night.

There is some indication of an amplification in the pattern across eastern North America by next weekend, hedging towards more large scale troughing by next weekend.

AVIATION /01Z SATURDAY THROUGH WEDNESDAY/. Short Term /Through Sunday/ . MVFR cigs dvlpg tonight in onshore flow with spotty drizzle/freezing drizzle possible. Conditions lowering to IFR and LIFR from sw to ne aft 21z Sat in RA for southern NH and coastal ME sites with a messy mix of PL/FZRA and wet snow for mtn sections. Sfc wind Sat night will gust to 35 kt at coastal TAF sites. Conditions improve to MVFR Sunday in cigs and sct -SHRA/-SHSN.

Long Term . An upper level low will bring periodic snow showers, reduced visibilities, and lowered ceilings at times on Monday, mainly across northern areas. Gradual clearing and mainly fair conditions are expected to return by midweek next week.

MARINE. Short Term /Through Sunday/ . Easterly winds increase tonight into tomorrow with increasing fog, drizzle, and eventually rain chances. SCA wind and waves likely develop tomorrow afternoon, before strengthening to a period of Gales Saturday night all waters. Lingering SCA's are likely all waters Sunday.

Long Term . A weak frontal boundary will cross the waters Monday into Monday night. A fresh breeze will gradually ease on Tuesday. Broad ridging will slowly build across the waters from Tuesday through the end of the week.

TIDES/COASTAL FLOODING. Persistent and strengthening onshore flow could produce some beach erosion during the midday high tide on Saturday. Some beach erosion and splash-over will be possible with the Saturday night and Sunday high tides.

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