Area Forecast Discussion National Weather Service Caribou ME 1225 AM EST Sun Dec 8 2019

SYNOPSIS. High pressure will build across the region overnight through Sunday. A warm front will cross the region later Sunday night through early Monday. Low pressure will track northwest of the region Tuesday. A cold front will cross the region Tuesday night through early Wednesday with high pressure sliding into the area on Thursday.

NEAR TERM /THROUGH TODAY/. 12:25 AM Update: The main challenges overnight are clouds and temperatures across the north. Temperatures in the north are all over the place with big fluctuations in space and time. Some spots have dropped below zero only to jump back to 10 to 15 above as clouds moved overhead. Other areas have seen temperatures drop rapidly as clouds moved out. Houlton is a good example dropping from +10F to -3F in the past 2 hours. There is another area of low clouds moving out of Quebec into far western Maine. Most of the models do not indicate these clouds make much progress into the FA, but based on the latest satellite trends they can't be ignored. Will make some updates to the sky grids and temperatures, but confidence in any one location across the north is very low.

Previous discussion: High pressure will build across the region overnight with partly cloudy/mostly clear skies across the north and mountains, with mostly clear skies across the remainder of the region. Have also included scattered flurries across the north and mountains through the early morning hours. Low temperatures will generally range through the single digits above and below zero across northern areas dependent on the cloud cover, to the single digits above zero interior Downeast with around 10 to 15 along the Downeast coast. Locally colder temperatures are possible. Have also updated the forecast to adjust for current conditions along with overnight temperatures and clouds.

Previous Discussion . High pressure wl build offshore in the morning with sfc winds backing to the southwest throughout the day on Sunday. Clds increase ahead of the next system but with H9 temps rising expect that maxes wl begin to climb twd normal.

SHORT TERM /TONIGHT THROUGH TUESDAY/. On Sunday night, warm advection will be ongoing as a warm front lifts through the area. Temperatures will be rising though the night into Monday. Some light snow is expected, but accumulations will generally be under an inch except possibly in the Saint John Valley where snow will continue into later Monday and up to 2 inches can’t be ruled out. The strong warm advection will produce a coastal front with temperatures and dew points reaching nearly 50F by late Monday. More significant precip will be concentrated towards this coastal front on Monday as the day progresses and it will be in the form of rain. Up to a half inch is possible by evening in coastal Hancock County and the heavier rain will continue into the evening as a powerful low level jet arrives near the coast and PW values shoot over an inch. This will produce another inch of rain along the coast overnight and wind gusts that will likely hit some 50 to 60 mph. The scenario of the rain, warm temperatures and strong winds usually correlates with power outages towards Bangor and the Downeast region. Power outages would be bad news as very cold Arctic air follows. The areas will be in the warm sector Tuesday with little rainfall and the cold front will cross Tuesday afternoon. The cold frontal passage won't produce much rainfall but could generate some wind gusts over 50 mph. The last concern with this system involves ice break-up and hydro. However, at this time, the heaviest rainfall towards the coast corresponds to the area of least snow cover and thin ice cover. Ensembles are not showing any potential issues on main stem rivers. Some urban and small stream issues are certainly possible Monday night into Tuesday morning.

LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/. Cold Arctic air settles into the area Tuesday night into Friday with the coldest day of the season to date on Thursday . and the coldest night of the season on Thursday night. An Arctic front may cause snow showers or squalls Wednesday afternoon or evening. For Thursday night, the model guidance is too high and have adjusted down towards the lowest percentiles of guidance. There's potential for -20F or lower readings in colder northern spots if the 1040mb surface high settles right over the area Thursday night. Warmer air arrives on the backside of the high Friday into Saturday. Low pressure arrives on Saturday with mixed precipitation, and between a coastal low and negatively tilted upper trough, there could be significant precip. Our current forecast features mostly snow and freezing rain in northern zones, but rain in the southern half of the forecast area.

AVIATION /05Z SUNDAY THROUGH THURSDAY/. NEAR TERM: Occasional MVFR ceilings are possible across the north and mountains into the early morning hours. Otherwise, expect VFR conditions across the region overnight into Sunday. Low level wind shear is a concern across mostly northern areas later Sunday at KFVE, KCAR, KPQI and KHUL.

SHORT TERM: Sunday night . MVFR cigs overspread the area with tempo IFR vis in northern zones.

Monday . IFR cigs overspread the area. IFR vis in snow is expected in the morning north of HUL. LLWS is expected by afternoon . mostly towards BGR, BHB and Machias.

Monday night . IFR cigs continue with LLWS. Wind gusts towards 60 mph from the southwest area possible towards BHB, Machias and Eastport.

Tuesday . IFR cigs continue with rain. A strong cold front crosses during the day with improvement towards MVFR cigs in the afternoon.

Tuesday night to Thursday . Mostly VFR conditions outside of some snowshowers late Wednesday afternoon and evening.

MARINE. NEAR TERM: Generally expect conditions below small craft advisory levels overnight through much of Sunday. However, gusts up to 25 knots are possible overnight. Winds will rise to aoa 25 knots late Sunday afternoon and increase toward gales by Sunday evening.

SHORT TERM: A strong gale is expected later Monday afternoon through Monday night. A few gusts to storm strength cannot be ruled out. Winds will diminish later Monday night into Tuesday, but a Small Craft Advisory will still required into Tuesday night. Cold air moving over the waters may prompt another advisory Wednesday night. Finally, another advisory or gale looks likely by Saturday night.

TIDES/COASTAL FLOODING. Astronomical tides will be relatively low during a significant wind storm Monday night and total water levels are not expected to be an issue, but the combination of wave heights and somewhat longer period waves mean some splashover is possible on coastal roads such as Seawall Rd on MDI and on Schoodic Point.

CAR WATCHES/WARNINGS/ADVISORIES. ME . None. MARINE . Gale Watch from this evening through Tuesday morning for ANZ050>052.
