Area Forecast Discussion National Weather Service Caribou ME 710 PM EST Wed Dec 11 2019
SYNOPSIS. An Arctic cold front will cross the region tonight. Cold Canadian high pressure will build over the region Thursday. A warm front will lift north of the area Friday. Low pressure will lift north across Maine Saturday. A cold front will cross the region Sunday. High pressure will build toward the region later Monday.
NEAR TERM /THROUGH THURSDAY/. 7pm Update . The previous forecast largely remains on track with just a couple minor near term tweaks of temperatures, which should begin steadying out or even rising with modest warm advection ahead of the front. Radar and satellite imagery shows a line of snow showers along a cold front extending from northern VT to Quebec City and moving eastward at about 30 to 35 knots. Based on this trajectory, an arrival of around 4-5z at Frenchville and around 6z for northeastern Aroostook County communities is estimated. The band of snow should weaken with eastward and southward extent tonight. Brief whiteout conditions are possible along with blowing snow, making travel hazardous late tonight. Patchy blowing snow and streamer snow showers will persist into the early morning behind the front.
Previous Discussion . With clear skies and light winds, temperatures will drop off quickly towards the single digits in northern zones this evening before clouds increase with the front. The Arctic front crossing tonight will introduce the coldest air of this winter season to date with 850mb temps dropping as low as -25C in northern Aroostook County by Thursday morning. The cold air advection and bitterly cold northwest winds will be the primary byproducts of the front for later tonight into Thursday. The only precipitation will be a brief snowshower with fropa, mostly in Aroostook County. Lapse rates steepen briefly with the front, but the front moves so quickly that accumulations more than a half-inch in a squall seem unlikely. The snow squall parameter does flash a signal after midnight in northern Aroostook County with those steeper lapse rates and potential gusts to 40 mph. Thus visibility in a squall could briefly go to zero for pre-dawn travelers in that region. The air is so cold that St Lawrence moisture may continue to provide flurries in the Saint John Valley well into Thursday morning. Highs on Thursday will only reach the low teens in northern Aroostook County and no more than the lower 20s towards Bangor and the coast. More notable will be subzero wind chills through the day in the northern half of the forecast area, and just single digits in the southern half of the forecast area. Winds will start to decrease during the afternoon as the high builds and radiational cooling will get off to a quick start after sunset.
SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY/. High pressure begins to exit across the Maritimes Thursday night, with a developing warm front across the region. Clouds will increase across the forecast area Thursday night, with a chance of snow showers across northern areas in the vicinity of the developing warm front. The warm front lifts north Friday. Expect mostly cloudy skies across the region Friday with a slight chance of snow or snow showers. The warm front moves north of the region Friday night, with developing low pressure across the Mid-Atlantic region. Expect rising temperatures Friday night with warm advection. Moisture also begins to expand north in advance of the Mid-Atlantic low with increasing precipitation chances. Across Downeast areas, expect a rain/snow mix early Friday night which will transition to rain overnight. Snow will transition to a snow/rain mix across central portions of the forecast area, with mostly snow across northern areas. The intensifying low lifts north across New England Saturday. Precipitation will remain in the form of rain Downeast Saturday. Snow will transition to rain across the remainder of the region through Saturday morning into the afternoon. Total snow accumulations through early Saturday, before the transition to rain, will generally range from 1 to 3 inches across the north and mountains with the greater totals across the Saint John Valley and higher terrain areas. Snow totals diminish southward across the forecast area with less than an inch expected across Downeast areas. Temperatures will be at near normal levels Friday, warming to above normal levels Saturday.
LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/. The low will lift across Maine Saturday night, reaching northern Maine late. Rain will persist Saturday night with near steady temperatures. The low will lift across the Gulf of Saint Lawrence toward Labrador Sunday. The low will draw a cold front across the region Sunday morning into the afternoon, though the exact timing is still uncertain. The heavier precipitation will exit across the Maritimes in advance of the cold front. Precipitation will remain in the form of rain in advance of the cold front, then transition to snow or snow showers following the cold front. Gusty southwest/west winds will develop following the cold front then persist into Monday. Snow showers could also linger across the north and mountains Sunday night into early Monday with partly cloudy/mostly clear skies Downeast. High pressure will build across the region Monday with decreasing winds along with partly cloudy/mostly clear skies. Low pressure should affect the region Tuesday. However, the track of the low remains uncertain. Precipitation types/amounts will be dependent on the eventual track. The low should exit across the Maritimes Wednesday. Generally expect partly/mostly cloudy skies Wednesday, with a chance of snow showers. Temperatures will be at above normal levels in advance of the cold front Sunday. Below normal level temperatures are expected Monday through Wednesday.
AVIATION /00Z THURSDAY THROUGH MONDAY/. NEAR TERM: VFR conditions are expected outside snow showers with the cold front, mostly at FVE. These snow showers could provide tempo IFR vis. Low level wind shear is possible at sites north of BHB later tonight into early Thursday morning.
SHORT TERM: Thursday night . VFR early. MVFR/IFR conditions developing overnight. A chance of snow showers across northern areas.
Friday . VFR/MVFR. A slight chance of light snow or snow showers.
Friday night . Conditions lowering to IFR/LIFR levels with snow north, a snow/rain mix across central areas and snow changing to rain Downeast.
Saturday . IFR/LIFR. Snow or a wintry mix transitioning to rain north, with rain Downeast.
Sunday . IFR/LIFR early. MVFR/IFR during the afternoon, then VFR/MVFR late. Rain early. Precipitation transitioning to snow or snow showers following a cold front. Gusty southwest/west winds following the cold front.
Monday . VFR/MVFR early, then VFR. A chance of snow showers early across the north and mountains. Gusty west winds.
MARINE. NEAR TERM: Continue to anticipate a quick hitting gale later tonight into early Thursday morning. SCA conditions will follow the gale into later Thursday afternoon.
SHORT TERM: Conditions below small craft advisory levels Thursday night. Small craft advisory conditions Friday through Saturday, with gusts possibly approaching gale levels later Saturday. Visibilities reduced in rain Friday night through Saturday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
