Synopsis
High pressure will cross the region today. Low pressure from the Midwest will approach tonight and moving across the area on Friday. High pressure will then build in from the west Saturday and Sunday.

Near Term - Through Tonight
1025mb surface high centered over warning Quebec with ridge axis extending thru warning New England as of 08z. Surface low over MO will heading toward the northeast tda as parent H5 low gets kicked out as s/wv drops into the Rockies this morning. Low clouds currently over Quebec and heading thru southern Maine are very slowly eroding as they head into dry air encompassing most of the FA early this morning. This has allowed temps to drop well below zero over the North s and will drop to near zero over the remainder of northern Aroostook before rising after sun-up.

Temps and dewpoints will rise in earnest once high builds east and return flow commences ahead of approaching system. Isentropic lift and overrunning will bring precipitation into warning zones this evening and with temps just slightly above frzg over Interior Downeast at onset expect that most of the area will see snow to start. Coastal Hancock will likely start off as a rain/snow mix this evening. Bangor region looks to remain all snow from onset until between 03z-05z when warm nose around 800mb increases above 0C as well as majority of the column down toward the surface. With swrly LLJ of between 50-60kts warm nose will orient itself fm nw to se with Downeast areas going from snow to a brief period of a rain/snow mix and then to all rain between 05z-08z Fri morning.

Further to the north warm nose will begin to make itself known with snow mixing with sleet after 08z tonight. By the end of the near term expect that the mix line wil make it over all of the northern areas with the exception of the very far portions of nwarning Aroostook.

For the overnight period expect that qpf will range from around 1 inch over coastal Downeast, mainly in the form of rain, to near 0.5 inches across the north. Snow accums will range from around 1 inch over coastal Hancock County to between 4-7 inches north of a Moosehead to Danforth line. Sleet and ice accums will be around 0.1 inches. Snow amounts have increased slightly in central areas from about Dover toward Houlton where best frontogenetical forcing looks to set up overnight.

Short Term - Friday Through Saturday Night
Friday... Warm advection continues Friday morning with precipitation continuing in the morning in the north, though becoming lighter than what was seen just before dawn. Most precipitation will have tapered off south of Millinocket for the morning. Precip type will be a challenge in the north where light precipitation remains. A warm above- freezing layer aloft will be over the north for all but perhaps the extreme north from Madawaska to Estcourt, leading to some sleet and freezing rain where surface temps remain below freezing in the morning, from about Patten and Houlton north to Caribou. The above freezing layer aloft will pivot east into New Brunswick and out of the area late morning or around noon, leaving just light snow/snow showers in the north, perhaps mixed with rain at times. Any additional snow accumulation in the afternoon will be light and mainly from about Caribou north. Temperatures Downeast will soar to the mid to upper 40s as they will be south of the weak triple point surface low pressure, and have a mild S/SW breeze. Areas of fog from Greenville and Millinocket south to the coast mainly in the morning, thanks to warm advection and above freezing temps combined with a wet snowpack. Concerned that fog could be rather dense in the morning for these areas.

Friday Night... Fairly strong cold advection through the night with increasing and gusty W/NW winds. Don't think winds will be quite enough for a wind advisory. A bit concerned about the dropping temps leading to any wet spots on roads icing up as temps either fall back below freezing, or further below freezing for areas in the far north that don't quite make it to freezing during the day Friday. Think that the threat of icy roads is the greatest in the north where precipitation will be ending last. Chance of snow showers mainly in the N/NW with the cold advection. Any accumulation should be very small.

Saturday... Chance of snow showers N/NW remains in the morning, but tapers off in the afternoon with partial clearing, as upper trough passes east of us and weak ridging and subsidence moves in. Seasonably cold on Saturday with highs from around 20 far north to around 30 Downeast. Breezy from the NW.

Saturday Night... Flat W/NW upper level flow over the area with weak high pressure at the surface. Seasonably cold, though uncertain how much decoupling can occur because of some clouds, mainly in the north.

Forecast Confidence... For Friday, roughly 25-50 miles of N/S uncertainty in the snow/sleet and freezing rain/rain line. A bit of uncertainty too in the amount of precipitation during the day in the far north. After Friday, models are in pretty good agreement into the weekend.

Long Term - Sunday Through Wednesday
Temperatures generally above average Sunday to Wednesday with a bit of a warming trend toward Wednesday, when readings could reach the upper 30s in the north and mid 40s Downeast. No definite storms Sunday through Wednesday, but some things to watch. One item of concern is a system passing south of us from W to E on Monday. While most models/ensembles keep precip offshore, a handful do bring precipitation into Downeast. A few ensembles do have a decent snow event Downeast if the northern envelope of low tracks pans out. For now though, the majority of models do keep the precipitation south of us. The other thing to watch toward Wednesday (and beyond) is the potential for rain and warm temperatures. The vast majority of models have a really mild airmass over much of the region from Wednesday to Friday, but there is still large disagreement on just how mild the airmass is this far north, plus a lot of disagreement on when/how much precipitation occurs. It looks like it will be hard to escape some rain/wind for most of the area at some point Wednesday to Friday, with the more likely period of wind/rain coming toward Friday. Also appears to cool off quite a bit next weekend after the potential rain/mixed precipitation event.

Marine
Near Term: Winds and seas will be below SCA (Small Craft Advisory) levels today before increasing this evening. Southerly wind gusts increase over 25kts after 00z tonight with gale force winds setting in over the outer waters after 05z thru the end of the period. Seas climb above 5 ft after midnight and increase to 8 feet over the outer waters Fri morning in southerly swell.

Short Term: Low end gale force W/SW winds Friday for all but inside waters, with seas up to 8 ft. Gales ease Friday night, but small craft wind/seas continue into Saturday. Likely below small craft Saturday night to Sunday night, then small crafts possible again Monday.
