Area Forecast Discussion National Weather Service Caribou ME 349 PM EDT Fri Oct 23 2020

SYNOPSIS. High pressure will move east of the Canadian Maritimes this evening. A cold front will approach from the west on Saturday. High pressure will build in Saturday night through Sunday, then move east Sunday night. Weak low pressure will cross the area Monday and Tuesday followed by high pressure for Wednesday.

NEAR TERM /THROUGH SATURDAY/. A weak warm front continues to lift northward across the area into the overnight hours. Expect plenty of clouds but some pockets of clearing seen Friday afternoon will continue into the early evening mainly across areas of the North Woods. Southerly flow south of the front will keep moisture feeding north at the low levels. The inversion stuck in place will mean we can expect low clouds, patchy fog and drizzle to develop. Travel overnight will be impacted with pockets of low visibility. Temperatures will remain mild overnight in the upper 40s to low 50s which is 10 to 20 degrees above average.

Low pressure with an associated cold front will track northeast into Eastern Quebec by Saturday morning. The trailing cold front will slide through the area starting around sunrise across western zones. Fog, Drizzle & Low Clouds will likely persist past sunrise Saturday especially in those prone upslope locations in the Central Highlands. At the same time Pops increase slight to chance by sunrise in western areas and push east during the daytime hours ending towards sunset. This cold front isn't very strong so showers aren't expected to be widespread. In fact Bangor to the Downeast coast will likely miss out on shower activity. The strongest push of southerly flow will be tomorrow sending Bangor region to the coast into the upper 50s with cooler temperatures to the north. As the cold front pushes through cold air advection kicks in on northwest flow and we will see temperatures fall.

SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY NIGHT/. On the backside of the cold front on Saturday night, cold air advection will result in windy conditions with stratocu/cu fields. The strength of the cold air advection may generate a few streamers from the St Lawrence and have added slight chc PoPs for Saturday night. The winds and cu fields continue Sunday, but both will diminish in the afternoon. Downslope areas such as Bangor will have more sunshine, but Sunday will probably be the coolest day of the fall season with highs in the lower 40s and wind chills in the 30s all day. Temperatures will drop off initially Sunday night into the low 20s north and upper 20s towards Bangor and the coast, but high clouds will rapidly increase later in the night in a fast southern stream upper flow. The low level wedge of cold air will likely be sufficient for mixed precipitation on Monday. Cold air damming will set up. In the cold, dry air, evaporative cooling will help eliminate boundary layer warmth. However, a warm nose in the 850-700mb layer will put an end to any snow by later in the afternoon . but sleet may hang on into the evening towards the St John Valley. Leaned towards NAM temps during Monday with the expectation of damming versus the warmer GFS, bias-corrected guidance or MOS guidance. Up to an inch of early season snow is possible in NW Aroostook County . with less east and south.

LONG TERM /MONDAY THROUGH FRIDAY/. Weak low pressure moves across the area Monday night with warm air advection and sufficient moisture for some fog in the southern half of the forecast area. Mixed precip will end for all areas except possibly NW Aroostook County. The cold front sweeps across the area later Monday night, but will stall not too far off the coast. Meanwhile, upper level clouds will continue to stream northeastward into the area from a low in the SW US. A wave will develop on the stalled boundary and cross the area Tuesday night. It will affect only the southern half of the forecast area and could bring snow to locations such as Bangor. Since the low is expected to be moving very fast and well to the south of Maine, it's hard to predict more than an inch or two on the high side. The big question will be later in the week when the SW US low kicks out and generates a significant east coast storm. ECMWF and GEMS have it well south with no impacts in Maine. Only the GFS suggests impacts to Maine on the northern periphery of the storm for Thursday night into Friday morning . but in the form of snow. Nonetheless, the situation warrants close watch in the coming days. All in all, it will be the coldest week of the fall season so far with highs now staying mostly in the 40s and lows in the 20s and 30s.

AVIATION /18Z FRIDAY THROUGH WEDNESDAY/. NEAR TERM: Basically MVFR this afternoon w/a few sites showing tempo VFR. Expecting conditions to drop to IFR for all terminals by the evening w/drizzle and fog setting up. SSE winds 10-15 kt will shift to the SSW by Saturday morning. Given the strong llvl jet overnight, LLWS is forecast for all terminals.

For Saturday, IFR w/drizzle and fog in the morning. Conditions are expected to gradually improve to MVFR by early afternoon. SW winds around 10 kts will be shifting to the NW late in the day at 10-15 kt as a cold front slides across the region.

SHORT TERM: Saturday night . VFR except tempo IFR in snow showers north of GNR and HUL

Sunday into Monday morning . VFR

Monday midday into Monday night . IFR due to cigs as well as snow north of HUL. Tempo LIFR for BGR and BHB Monday evening in fog.

Tuesday . MVFR cigs possible north of HUL in the morning . otherwise VFR.

Tuesday night . VFR except tempo IFR in snow for BGR

Wednesday . VFR

MARINE. NEAR TERM: SCA stays in place w/seas already hitting 5-6 ft w/a swell period of 11 seconds. Seas are expected to build to 6-8 ft tonight into Sat due to the swell from HRCN Epsilon. ESE winds 10-15 kt will shift to the S later tonight.

For Sat, SSW winds 10-15 kt will shift to the W late in the day as the cold front slides across the water.

SHORT TERM: SCA conditions will be continuing into Sunday morning and the advisory may need to be extended. SCA conditions return Monday night and again on Friday.

CAR WATCHES/WARNINGS/ADVISORIES. ME . None. MARINE . Small Craft Advisory until 8 AM EDT Sunday for ANZ050-051.
