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 Gray ME 1110 PM EST Fri Dec 1 2023

SYNOPSIS
Starting with a quick-hitting, light-rain system this evening and tonight, the weekend will be a generally showery and cloudy one. Attention then turns to the passage of a potential significant winter storm early next week. Uncertainty remains unusually high with confidence in details similarly unusually low, however there is increasing confidence in accumulating snow over the interior and into the mountains. This will have to be watched closely with potential impacts to the Monday morning commute due to wintry conditions.

NEAR TERM /UNTIL 6 AM SATURDAY MORNING/
1100 PM Update... Minor changes to reflect latest observational trends. Rain is continuing to quickly exit NH and southwestern ME and water vapor imagery is indicating that drier air is already moving back in aloft. Rain and mountain snow will continue to taper off through the overnight hours, although some showers will likely persist across the far north/mountains through much of the night. Fog, some locally dense will reduce visibility at times through tomorrow morning so please use caution if traveling.

Previously...
700 PM Update...
Northeast radar mosaic and sfc observations continue to show rain advancing from southwest to northeast over our region in association with a weak shortwave trough. Still expecting rainfall amounts of generally less than a third of an inch with light snow accumulations across the higher terrain and perhaps near the Canadian Border. Areas of fog will form overnight as well, some of which may become locally dense so this will be something to watch. The inherited forecast remains in good shape with only minor adjustments needed to account for latest trends.

Previously...
An active weather pattern featuring fast, zonal flow aloft delivers a quick-hitting wave of precipitation this afternoon into the overnight. Impacts should be little to none with weak wind fields, weak forcing, and the blink-and-you-miss-it speed of the system. Model trends have been fairly steady with this system for the last several runs, with total QPF ranging from around 0.2-0.4" toward the north, to less than 0.2" through the foothills and south.

One trend that has continued is a slight warming/less snowy trend... owing to the slower movement of a cold front approaching from the north, which has stalled just north of the Canadian border this afternoon. Thus, temperatures in the 40s are being observed even in the northern valleys (50s further south) which given southwest flow and an associated lack of a CAD and dry air to wet-bulb-cool doesn't leave much opportunity for snowfall accumulations. Would expect accumulations to be limited to 2500 ft and above, with a slushy inch or two of potential there this evening. After the system moves on, low ceilings, drizzle, and fog/mist are likely to develop with lows in the 30s to near 40 at the coast

SHORT TERM /6 AM SATURDAY MORNING THROUGH SATURDAY NIGHT/
On Saturday, a stalled front will remain perched to the north near the international border... providing a focus for continued low overcast over the northern half of the area and through the mountains, along with light shower activity (mostly rain).
Further south, there's greater likelihood for higher ceilings and some breaks in the clouds. Temperatures likewise will be cooler and lower toward the north, hanging nearly steady in the 30s whereas southern zones may make a good run to 50.

The front that had been hung up near the international border sees a renewed push southward Saturday evening as high pressure builds toward the north. While this should clear out remaining measurable precipitation, this will also usher in a steady northeast wind overnight... the start of the cold air dam which will become quite relevant in the long term forecast discussed below. The low- and mid- levels look to remain saturated, and with subsidence from pressure rises would expect low ceilings to fill in over most places with lows in the 20s north, 30s south.

LONG TERM /SUNDAY THROUGH FRIDAY/
Overview: Low pressure will bring accumulating snow for the mountains and foothills, rain to the coast and southern NH.
Uncertainty exists between these regions, as a rain or snow line will fluctuate over time. Precipitation may be heavy at times Sunday night, with a slick Monday morning commute possible.
Departure of the low may be slow, with lighter precipitation lingering through the day Monday. High pressure will attempt to nose into the region midweek, with drier and cool conditions.

Details: Potential impacts for late weekend storm should be fairly consolidated to winter hazards, due to snow accumulation, and perhaps a period of gusty winds. No flooding, strong winds, or coastal flooding is currently forecast.

Initial disturbance has entered off the west coast this afternoon, and will travel across the Inter Mountain West tonight. The disturbance will be picked up in the Central Plains via a rapidly strengthening jet from TX to southern New England.

Model consensus has improved from this time yesterday in regards to general low handling and transition. This brings the center of sfc low up the Eastern Great Lakes Sunday with a transfer to a coastal low overnight into Monday morning. This period is also when precipitation is expected to be the most widespread with increased rates for our CWA.

Should this track and handoff continue, precip types should be fairly straightforward in regards to a rain/snow system. The cool column doen't show too many warm hints that would cause a period of accumulating sleet or ice. What will continue to need refinement is where this transition line will lie. For this forecast cycle, opted to continue to blend cooler sfc temps in during the event. This is a reaction to cool drainage from north high pres across the area Sat night. This flow largely remains in place through Sun morning, and perhaps even a bulk of the event considering the high's strength. As mentioned above, little in the way of a warm layer appears likely aloft, so surface temps will play a large role in accumulation. The NAM is by and far the coolest the longest for the area, with cold air damming keeping much of the area 32 or lower outside of the immediate coast. CAD signal can be seen in other global models as well, and this gives confidence in this mechanism being quite strong.

At this time range, it is enough to keep a slimmer rain/snow line favoring all snow for the mountains, foothills, and into portions of the interior. Amounts come in heavy, with up to a foot possible in the higher elevations. With lighter winds, upslope/downslope may be hard to define, and it will be more temp/ratio based for elevation amt differences. The bulk of this falls during Sunday night, picking up for the Sunday evening commute.

The uncertainty rain/snow zone, wrapping from Lake Winnipesaukee through much of interior ME towards the Midcoast and ME Capitol region, will harbor much of the going debate over the next forecast cycles. Areal coverage of surface temperatures that remain A) supportive for snow and B) cool enough to accumulate is tricky designate. A clearer picture will come with additional hires guidance. Currently weighed towards a cooler solution, but there remains a solid 8 to 10 degree temp spread for some locations in the band outlined above. Thus confidence is still low here. Towards the immediate coast, rain will tend to be the primary precip type, but consideration will be needed for the Monday morning period where wrap around, ongoing precip may be mainly snow as rates being to taper off. A safe bet would be to be on alert Mon morning for potential slick travel conditions throughout the CWA.

The trough that lingers overhead w/ exiting low should keep some snow showers in the region through the day Monday. These features can sometimes harbor a thin region of enhanced rates, and will need to keep an eye out for the formation of this.
Otherwise, high pressure will look to nose into the region overnight through the middle of next week. This will generally favor cooler temps and offshore wind directions.

AVIATION /04Z SATURDAY THROUGH WEDNESDAY/
Short Term...VFR this afternoon trends into widespread restrictions overnight with a 3-4 hour period of -RA coincident with lowering MVFR ceilings... followed by a potential period of IFR/LIFR CIGs and VSBY restrictions due to BR and/or -DZ.
Improvements are expected on Sat but may take until the afternoon to occur, or may only improve to MVFR. In general, restrictions are most likely to develop and persist further north for tonight and tomorrow. Lowered CIGs, potentially to IFR/LIFR along the coastal plain, are expected to develop again Sat night. Winds are forecast to remain predominantly light AOB 10 kts through the period.

Long Term...MVFR to IFR expected Sunday. Vis will be reduced overnight into Monday morning due to RA and SN, with SN mainly across interior terminals and away from southern NH. RA favored elsewhere. Precip rates decrease through Monday, with vis improvement but low ceilings still likely. Ceilings do improve into Tuesday and Wednesday.

MARINE
Short Term...Gradient flow out of the southwest continues through tonight into tomorrow as an area of low pressure approaches from the west. There is a brief window of time where wind gusts may reach 25 kts between 00Z-06Z. Winds turn northerly and then northeasterly Sat evening and overnight, remaining light.

Long Term...A period of small craft conditions will possible Sunday night into Monday. Winds and wave heights will be highly dependent on how low pressure develops in the region during this period. Current forecasts call for strengthening low pressure to move towards the Great Lakes Sunday, redeveloping over the Gulf of Maine through the evening and overnight into Monday. The low will then exit east.

GYX WATCHES/WARNINGS/ADVISORIES
ME...None.
NH...None.
MARINE...None.
