Synopsis for stonington me to merrimack river ma out to 25 nm a weak area of low pressure moving along a cold front crosses into the waters tonight with a small window of time when winds may gust to near 25 kts. The cold front finally drops through the waters Saturday evening and overnight with fresh northeast flow developing in its wake. A stronger coastal low is likely early next week, moving through the gulf of maine on Monday. High pressure then slowly builds back across the waters through the middle of the week.

Area Forecast Discussion National Weather Service Caribou ME 914 PM EST Fri Dec 1 2023
SYNOPSIS
A cold front will cross the region overnight, then exit across the Gulf of Maine Saturday while weak low pressure moves along the front. Low pressure will approach from the southwest on Sunday and cross the Gulf of Maine Monday. The low will continue into the Maritimes Monday night followed by high pressure Tuesday. Canadian high pressure settles over the area on Wednesday.
NEAR TERM /THROUGH SATURDAY/
9:14 PM Update: Precipitation continues to spread into the FA from the southwest with rain moving into Bangor and Bar Harbor.
The precipitation is expected to remain in the form of rain in Bangor and along the coast overnight. As the precipitation moves up into southern Piscataquis and central Penobscot counties it will likely be a rain/snow mix that may change to snow overnight. It will take longer for the precipitation to reach far northern portions of the FA it fights some drier air in the mid levels as evident on the 00z Caribou sounding, but from around the Katahdin Region north it will fall in the form of snow. Made some small adjustments to the PoPs for the remainder of tonight based on the latest radar trends and observations.
Previous discussion: A weak cold front will settle southward across the region tonight, approaching the Downeast coast late, while weak low pressure moves along the front. The front then settles across the Gulf of Maine Saturday while a second low tracks along the front. High pressure will build north of Maine tonight through Saturday. Aloft, an upper level disturbance will also cross the region overnight through Saturday. Based on critical thickness values, expect precipitation will remain in the form of rain across Downeast areas tonight, Across central areas, expect a rain/snow mix will transition to snow overnight. Across northern areas, precipitation will be in the form of snow. However, high pressure to the north of Maine will help limit precipitation totals across northern Maine. The secondary low and upper disturbance will keep snow chances across central and northern portions of the forecast area Saturday with additional light snow accumulations expected. Lesser precipitation chances will exist Downeast Saturday,. Expect precipitation in the form of rain Downeast early Saturday. However, colder air will filter southward during the afternoon in the wake of the secondary low and exiting cold front. Thus, expect rain will mix with, or transition to, snow across Downeast areas during the afternoon with little accumulation expected. Generally expect 1 to 3 inch, locally up to 4 inch, snow accumulations across central and northern areas tonight through Saturday with the lesser totals across the Saint John Valley nearest high pressure located north of Maine. Low temperatures tonight will range from the mid to upper 20s north, to the mid to upper 30s interior Downeast with around 40 along the Downeast coast. High temperatures Saturday will range from the lower 30s north, to the lower 40s interior Downeast with mid 40s along the Downeast coast. Temperatures will begin to fall during the afternoon.
SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY NIGHT/
Snow showers will come to an end Saturday evening as drier air works into the area. Cannot rule out isolated snow showers in eastern areas near New Brunswick border through the night before ending by daybreak. Strong surface high pressure settles in north of Maine allowing for the winds to shift N-NE which will be key for the next potential system mentioned below. Clouds will remain in place with temperatures falling back into the mid to upper 20s across the northern 1/2 of the CWA with teens in the far NW North Woods. Southern 1/2 of the CWA falls back into the low 30s around that 32F mark.
Sunday will feature a negatively tilted shortwave at 500mb transecting the eastern Great Lakes states. 12z operational and ensembles are in better agreement of this shortwave being the primary driver in precipitation while a secondary shortwave SW of the primary playing some role but not as much as previous runs. High pressure to our Northeast favors strong cold air damming (CAD) which sets up during the day Sunday. Have opted to lower highs a degree or so than previous forecast. Highs top out in the upper 20s to low 30s across the north with mid to upper 30s for the southern 1/2 of the CWA. Expect a cloudy day with moisture advecting into the area as surface low pressure over western New York begins to consolidate into a develop surface cyclone off Long Island coast. The 500mb trof will keep this system moving but expecting some deepening with upper level divergence setting up above the system. By late day expecting light precipitation to develop from SW to NE across the area in response to the moistening boundary layer and surface forcing.
The CAD will strengthen during the evening as low pressure strengthens as the low tracks just inside the benchmark but its going to keep chugging along to the east. A tight thermal gradient will likely develop along the Downeast coast with strong CAD in place. Expecting light to moderate snow from basically along the Route 1 corridor inland to the Central Highlands and Baxter region. North of there generally light snow into the St. John Valley. There remains a little uncertainty on the mesoscale features that play out but cannot rule out a period of heavy snow with higher ratios in the Central Highlands from the Moosehead region to Interior Downeast. Another uncertainty exists right now is how fast the original low consolidates into the strengthening primary low. This could hamper snow totals across the area but for now opting to not get focused on the snow totals due to uncertainty. Confidence is increasing on totals that will require some form of headlines but for now will mention in the HWO. Those planing travel Sunday night into Monday especially Monday AM commute should expect an impact from this system. Steady precipitation will come to an end and taper to snow showers Monday afternoon.
Probabilities of 4"+ are in the 50-90% range from Interior Downeast including Bangor northward into the County with the bullseye of 75%+ from Moosehead to Baxter. Probabilities of 6"+ have increased with 30% at Bangor, 70% at Greenville and 55% in Houlton. See our website www.weather.gov/car/winter for more details. At this point a large chunk of the central CWA has a 30-50% chance of exceeding warning criteria. Keep with the forecast for potential changes including adjustments to the totals.
LONG TERM /MONDAY THROUGH FRIDAY/
Looking into the long term our Negative NAO will start to slowly trend neutral based on the latest GEFS trends. PNA starts slightly positive will trend neutral to slightly negative. This favors cooler than normal temperatures and generally dry conditions across the CWA. Beyond the storm Monday the pattern is generally cyclonic with long wave trof associated with low pressure well to our north. Pieces of shortwave energy will transition the long wave but not expecting much organized precipitation other than snow showers. High temperatures generally 5-10 degrees below normal into the 20s and 30s from N to S and lows the low teens north with upper teens south. Cannot rule out a few days with enough clearing for lows in the single digits to around 0F across the far North.
AVIATION /02Z SATURDAY THROUGH WEDNESDAY/
NEAR TERM: VFR/MVFR will lower to MVFR/IFR, occasional LIFR, overnight into Saturday. Snow developing north tonight. A snow/rain mix transitioning to snow central areas. Rain Downeast. Snow north, rain Downeast, Saturday. Rain possibly mixing with snow during the afternoon. Light and variable wind overnight. Variable winds 5 to 10 knots, becoming northeast/north Saturday.
SHORT TERM: Sun...VFR becoming MVFR in the afternoon. -SN develops late day at southern terms to north terms. NE winds 5-10kt.
Sun Night...IFR/LIFR for cigs/vsby. SN likely. BHB may see a mix of RA/SN. NE 5-15kt.
Mon...IFR/LIFR through 18z. -SN likely. SN/RA mix at BHB.
VFR/MVFR south after 18z, MVFR/IFR north after 18z. NE winds 10-20kt shifting N 5-15kt late day.
Tue-Wed...VFR/MVFR. Tue winds NW 5-15kt. Wed winds N-NW 5-10kt.
MARINE
NEAR TERM: The wind and seas are expected to remain below small craft advisory levels overnight and Saturday. As of 9 PM, seas are running 4 to 5 ft on the coastal waters, and will continue to slowly subside overnight. Rain and patchy fog tonight. A chance of rain Saturday.
SHORT TERM: Sat night into early Sun eve expect winds and waves to be below SCA conditions. E-NE winds generally less than 20kt with seas 2-4ft with a period of 8-9 seconds. Sun Eve expect E-NE winds increase sustained 20-25kt with gusts to increase to 30kt. Seas build 4-5ft with a period of 5-6sec.
Winds will shift N late Mon AM behind the departing low pressure into the Maritimes. Winds should remain below SCA into midweek behind the storm.
