Area Forecast Discussion National Weather Service Gray ME 434 PM EST Sat Dec 14 2019

SYNOPSIS. A complex frontal system crosses the area tonight with strong winds over much of the area Sunday. High pressure builds into the area Monday. Low pressure tracking from the Ohio Valley towards southern New England will bring mainly light to moderate snow to the area late Monday night into Tuesday afternoon. Snow showers are possible Wednesday followed by much colder air for the end of the week.

NEAR TERM /THROUGH TONIGHT/. A complex storm system continues to impact the northeast CONUS today with the local area of central New England in a relative lull at this hour. The window for heaviest rainfall has passed by this time with a shortwave warm frontal axis crossing into New Brunswick and dry air intruding aloft, evident on satellite imagery. In its wake, patchy dense fog has taken over as temperatures hover in the mid-40s over much of the area, upper-30s to near 40 across the north (and at the summit of Mt Washington).

Showers remain on the table through the evening under the larger trough aloft with moisture depth remaining upwards of 1-1.25" PWAT. Then, the frontal triple point crosses bringing one final round of moderate rainfall potential, mainly in the Whites and western Maine mountains owing to southeasterly low- level upslope flow. With the exception of the mountains, PoPs decline steadily overnight after the surface system crosses, drying entirely south of the mountains by dawn Sunday with northwesterly flow taking over. There will be overlap between temperatures falling over the mountains and drying, so expect lingering rain showers to switch to snow showers after midnight across higher terrain and areas north. With northwesterly winds comes cold advection, however, which will allow for better mixing of winds from aloft down to the surface. More on winds below in the short term.

SHORT TERM /SUNDAY THROUGH SUNDAY NIGHT/. Sunday, mid-level wind fields ramp up on the backside of a departing trough aloft as its axis sharpens, rotating north- northeastward into eastern Canada. Models are fairly consistent bringing a belt of h850 winds exceeding 50 kts, locally 60 kts, through the area during the day Sunday when diurnal and cold advection mixing will maximize. This yields wind gusts at the surface to near 40kts, but favorable downsloping over portions of central/southern NH and western Maine will tend to allow a greater portion of strong winds aloft to mix to the surface. A Wind Advisory has been posted for these areas as a result in coordination with other offices. This may need to be expanded into western New Hampshire, but confidence in mixing conditions is lower there, so will allow for another forecast cycle to determine if an expansion will be necessary.

Along with gusty winds, upsloping cloud cover persists over the mountains Connecticut River Valley with snow showers steadily decreasing through the day. Accumulations ought to be light, on the order of 1-3" with higher amounts possible over higher terrain.

LONG TERM /MONDAY THROUGH SATURDAY/. High pressure will build into into the region Monday with high temperatures slightly below normal. Clouds will be on the increase late Monday as a wave of low pressure moves from the Ohio Valley towards southern New England. The 14.12Z model suite is in general agreement with this low tracking over southern New England late Monday night into Tuesday night leaving us on the cold side of the system.

There are some differences amongst global models in the placement of the axis of heaviest precipitation as well as how much warm air aloft can move northward leading to p-type issues in southern areas. The GFS is the wettest and warmest with the axis of heaviest precipitation over south central New Hampshire into western Maine and snow changing to mixed precipitation over southern New Hampshire. The ECMWF places the axis of heaviest precipitation over Massachusetts and is colder leading to a mainly snow event. The NAM12 has trended slower with this system delaying precipitation until mid morning Tuesday and is similar to the GFS in the placement of heaviest precipitation and bringing a changeover to mixed precipitation over southern New Hampshire. For this forecast package have gone with a multi model blend which yields a mainly snow event and amounts near advisory levels. Although amounts are not overly impressive this system bears watching as it looks to impact the Tuesday morning commute.

The Tuesday system will be followed by a sharp trough that swings through Wednesday bringing scattered snow showers to much of the area. This trough will bring much colder air to area with H8 temperatures dropping below -20 C Thursday morning. The end of the week looks dry and cold with temperatures slowly moderating into the weekend.

AVIATION /21Z SATURDAY THROUGH THURSDAY/. Short Term . /Widespread LIFR in FG and low ceilings impacts terminals this afternoon in the wake of heavy rainfall seen earlier today. IFR ceilings gradually lift late this evening after another round of rain showers, scattering to MVFR and IFR between around midnight and 5 AM from SW to NE. MVFR, briefly IFR near dawn, ceilings persist at HIE and LEB through tonight into tomorrow morning with rain switching to snow before drying entirely.

Mainly light and variable winds this afternoon increase out of the southwest tonight, becoming gusty by dawn, and strengthening further out of the west tomorrow. Expect gusts exceeding 30 kts for all terminals on Sunday with terminals south and east of the mountains expected to have gusts reaching upwards of 40 kts at times. A period of westerly LLWS is possible around dawn on Sunday before stronger winds begin to mix to the surface.

Long Term . Cloud cover will increase and -SN will break out from SW to NE Monday night into Tuesday that may bring restrictions. Scattered SHSN possible Wednesday followed by improving conditions into the weekend.

MARINE. Short Term . Gale warnings continue through tonight with southerly winds turning southwesterly by dawn, westerly by mid- Sunday. Seas remain greater than 10 ft over the waters tonight, topping 15 ft off the MidCoast tomorrow afternoon as wind gusts ramp up to 40-45kts.

Long Term . Winds relax Monday as high pressure build into the area with gusts dropping below 20 kts Monday afternoon. Low pressure tracking over southern New England will bring -SN over the coastal waters Monday night into Tuesday. Gales are possible Wednesday night into Thursday with strong NW winds.

HYDROLOGY. QPF/Flash Flooding: Heavy rain has moved out of the area with flash flood threat waning. Widespread observed rainfall amounts of 2-3" along the immediate coastal region had led to high water impacts and numerous road closures due to poor drainage and small streams exceeding bankfull. Flash flood warnings have been transitioned to areal flood warnings as basins drain over frozen grounds.

Rivers: With most of the expected rainfall on the ground, river forecasts can be considered high confidence at this point, with flooding presently observed on the Suncook at North Chichester (cresting mid-Sunday at minor flood stage) and on the Presumpscot at Westbrook (cresting this evening at minor flood stage). The Swift River is also forecast to barely reach flood stage but may be complicated by river ice. Most basins over southern and central New Hampshire and a few over portions of southwest Maine are forecast to reach action stage owing to snow melt and rainfall.

GYX WATCHES/WARNINGS/ADVISORIES. ME . Flood Watch until 7 PM EST this evening for MEZ018>028. Wind Advisory from 10 AM Sunday to 1 AM EST Monday for MEZ007>009-012>014-018>028. NH . Flood Watch until 7 PM EST this evening for NHZ006-008>010- 012>015. Wind Advisory from 10 AM Sunday to 1 AM EST Monday for NHZ004- 006-008>010-012>015. MARINE .
