SYNOPSIS
An occluded front approaches tonight, crosses the region Saturday, then exits across the Maritimes Sunday. A strong cold front crosses the region Sunday night into Monday. High pressure then builds across the region later Monday into Tuesday. Low pressure approaches Wednesday.
NEAR TERM /THROUGH SATURDAY/
6:03 PM Update: Weak frontal systems will approach the FA tonight with a warm front late this evening to be followed by a cold front Saturday morning. Precipitation in the form of scattered rain showers will develop from the west late this evening and overnight. A disturbance tracking along the weak cold front and rounding the base of an upper trough is expected to develop into an area of steadier rain toward daybreak Saturday across the southern half of the FA. A mild south flow combined with increasing clouds tonight will keep lows much miler than the past couple of nights with most spots tonight expected to drop into the lower 40s. The ongoing forecast handles this well with only minor tweaks to account for the current and expected conditions tonight.
Previous discussion: Surface/upper level ridging exit across the Maritimes tonight, with an occluded front approaching the region late. Scattered showers will occur across the forecast area tonight. The occlusion will cross the region Saturday. Aloft, an upper trof approaches with a disturbance rotating through the base of the trof. Models have been trending toward more pronounced troffing with a stronger disturbance moving through the trof. This has led to a more pronounced area of rain, mostly south and east of a line from Houlton to Dover-Foxcroft, with the greater totals across Downeast areas. Rain totals diminish rapidly northwest of that line. The rain will begin to taper to showers later Saturday. Low temperatures tonight will range from around 40 to the lower 40s across the forecast area. High temperatures Saturday will generally range from the upper 40s to lower 50s with the cooler temperatures occurring with the most persistent rain.
SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/
Saturday Night...
Some showers could persist early in the evening along and south/east of I-95. However, they will quickly move off to the east leaving us dry with skies becoming mostly clear. Some slightly cooler and drier air will be moving in from the west, with a bit of a westerly breeze persisting through the night.
Sunday...
A strong upper trough with a strong associated surface cold front will begin approaching us from the northwest on Sunday.
Cold front won't yet be here by the end of the day, but the approaching trough should provide enough support for a chance of showers, mainly over the north. Should be mostly rain, but can't rule out some graupel. Highs Sunday generally in the low to mid 50s with a westerly breeze 10-15 mph with higher gusts.
Sunday Night and Monday...
All models/ensembles have latched onto the strong Arctic cold front for later Sunday night, with an associated strong upper trough, diving southeast into our area. This is quite a change in thinking from a couple days ago, when models had it quiet and mild, but the models shifted hard and now appear locked in. The strong cold front appears to reach extreme northwest Maine around midnight, progressing southeast to around Houlton around dawn. The cold front and cold air push behind the front will be a lot stronger in the north than Downeast. There is some concern for snow showers or perhaps snow squalls with and just behind the cold front. Thankfully, the front will be moving through around a time of less impact in the north in the pre-dawn hours mostly. Also, without diurnal heating, the line of snow showers with the front will probably be weakening as it approaches and moves through our area. Still, bears close watching. Think that any snow accumulations should be less than an inch and limited to areas north of Houlton and Greenville, as there just isn't much moisture to work with. Also, any snow we do get could blow around Monday morning with gusty northwest winds behind the front gusting 25-35 mph in the north. Temperatures will drop handily behind the front especially in the north, with readings in the mid to upper 30s before the front and low to mid 20s behind the front. Don't expect much of a warmup Monday afternoon, with highs only around freezing in the far north. Not quite as cold Downeast, with highs Monday in the low to mid 40s. Expect post-frontal snow showers Monday morning to be short-lived, with dry conditions by midday, and clearing skies.
The airmass moving in Monday will be bone-dry, with dewpoints late Monday around zero in the north and 10 above near the coast.
LONG TERM /MONDAY NIGHT THROUGH FRIDAY/
Surface high pressure briefly builds in Monday night. If we decouple, could get quite chilly. Going for lows generally in the 20s with some teens cooler valleys. Airmass then warms significantly Tuesday and Tuesday night ahead of the next approaching system, with the cold airmass retreating to our north. The next weather system for later Tuesday night through Thursday is going to be a tough one. We have not only a deepening trough approaching from the west, but also an upper low further north that may merge into the approaching upper trough. If they merge, we could see a strong, cold upper low park itself over the area. If not, things could be more progressive and we could get a quick shot of precip with things then drying out. The predictability is not high with this sort of setup, and many things could happen. We will very likely get some precipitation some time late Tuesday night to Thursday, with progressively colder air and perhaps a changeover to accumulating snow toward Wednesday night or Thursday. Whether we change to accumulating snow depends on the position of the upper low and how long it hangs out over our area.
AVIATION /22Z FRIDAY THROUGH WEDNESDAY/
NEAR TERM: VFR conditions expected this evening. MVFR conditions with scattered showers are then expected after midnight. MVFR/IFR, occasional LIFR, with rain Saturday. The lowest ceilings are expected at KBGR and KBHB. South winds 10 to 15 knots with gusts up to around 20 knots tonight.
South/southwest winds 10 to 15 knots with gusts up to around 20 knots Saturday. Southwest low level wind shear later this evening through early morning.
SHORT TERM: Saturday Night... MVFR/IFR early Downeast in showers, becoming VFR areawide by about 3z. W wind 5 kts.
Sunday...Mainly VFR, though brief MVFR in scattered showers from MLT and GNR north. W wind 10-15 kts with gusts around 20 kts.
Sunday Night...VFR until after 6z in the north, when a cold front moves in from the NW. This could bring brief MVFR/IFR to areas from PQI north. Winds will be SW 5-10 kts, shifting to the NW 10-20 kts with gusts to 30 kts late and in the north behind the cold front.
Monday...Generally VFR, except local MVFR early mainly N of HUL.
W/NW winds 10-20 kts with gusts 20-30 kts.
Monday Night...VFR with light winds.
Tuesday...VFR with S wind 10-15 kts.
Tuesday Night and Wednesday...Low confidence, but potential for MVFR/IFR late Tuesday night into Wednesday with rain. Generally S wind 10-20 kts.
MARINE
NEAR TERM: Winds/seas below small craft advisory levels tonight through Saturday. Increasing shower chances late tonight. Rain Saturday.
SHORT TERM: Next chance of small craft comes Sunday night and Monday. Then a likelihood of small craft late Tuesday into Wednesday.
