Area Forecast Discussion National Weather Service Gray ME 344 PM EDT Mon Oct 25 2021

SYNOPSIS. A strong coastal storm system will enter the southern New England coastal waters Tuesday, before forming a loop Tuesday night into Wednesday night. Rain and strong northeast winds expected through Wednesday. Quieter weather is then expected for both Thursday and Friday before another storm system approaches from the south by this weekend.

NEAR TERM /UNTIL 6 PM THIS EVENING/. A few pockets of rain will continue tonight, mainly over southern and central sections as a moist flow continues over the region. Any remaining snow showers should be limited to the highest peaks this evening. Patchy fog will continue as well.

Steady rain may make it into southern portions of the forecast area per latest HRRR and other solutions later tonight. The 12Z model suite is in general agreement intensifying an area of low pressure off the Mid Atlantic coastline after 06Z. Forecast confidence remains relatively low due to the track and intensification details of the system. However, strong gusty winds and heavy rainfall will likely impact southern portions of the forecast area.

SHORT TERM /6 PM THIS EVENING THROUGH TUESDAY NIGHT/. Rapid cyclogenesis will be underway on Tuesday as the storm unfolds near the 40 degrees north and 70 degrees west benchmark. All models depict a retrograding storm forming a loop over the southern New England waters Tuesday afternoon and Tuesday night. Our impacts will be determined by how far north the system can make it prior to making the left hand hook. In any case, winds will increase across our region on Tuesday, especially along the coast where strong winds are anticipated. Depending on the storm intensity and track, wind advisories may be needed for the coastline. Currently, wind probabilities of around 15 percent for wind gusts over 42 kts are expected in Portland with 35 percent chance in these wind levels for Rockland. Bufkit profiles continue to pick up on this low level jet as well.

Rain will continue as well and be heavy at times over southern sections through Tuesday night along with strong wind gusts. Have leaned towards the Canadian model in terms of QPF once again which is a good compromise solution for this forecast package. A couple river points may have flood issues in southern New Hampshire and there may be issues with urban flooding due to clogged drainage areas.

LONG TERM /WEDNESDAY THROUGH MONDAY/. Wet and Windy conditions taper Wednesday evening, for calmer conditions until the weekend.

As a large and powerful cyclone spins off the east coast, a mid/upper jet will slide through the Ohio Valley. This takes the rug from underneath the system’s southerly moisture transport, while high pres to the north hectors the northward movement of the low as it turns in place. The slow easterly movement will focus remaining rainfall through Wednesday afternoon over the waters and coastal communities. There will also be some upslope enhanced rainfall on eastern higher terrain faces, in particular southern NH. Otherwise, trended remaining QPF for Wed down.

Dry air may quickly enter the low levels in the afternoon, allowing for some sub 900mb mixing. With a relatively close proximity to a potent NE 50-65kt LLJ just off the coast, Wed will be windy with inland gusts up to 30 mph possible. These could stand increasing if short term guidance trends support.

Influence from the storm finally wanes Wed evening and overnight. Thurs remains dry and breezy, but winds turn north in wake of the exiting low. The northerly flow will advect cooler temps in overnight, with a return to widespread 30s.

Dry conditions continue Friday with high pres to the north. Model guidance came in slower with the onset of another possible storm this weekend. Rain is forecast to arrive ahead of low pressure tracking through the Ohio Valley and into New York. While timing seems in fairly good agreement for a day 7 system, evolution is still uncertain. This revolves around how progressive the system is on the heels of exiting high pressure, as well as if it remains a closed sfc low or garners more influence from a longwave dropping into the Upper Midwest. Either way, there is decent confidence in a damp weekend for much of the area, with temperatures again trending above normal into the mid to upper 50s.

AVIATION /18Z MONDAY THROUGH SATURDAY/. Short Term . IFR with areas of LIFR tonight through Tues night with low ceilings and rain. Strong NNE winds increase Tues afternoon, gusting 20-30 kt, at southern and central TAF sites. Perhaps higher in vicinity of coastal KPWM, KRKD, and KPSM.

Long Term . Windy conditions continue Wed afternoon with some gusts up to 30 kt mainly across central and southern ME. Conditions do improve to MVFR/VFR through the afternoon, with MVFR possibly returning overnight into Thurs AM.

MARINE. Short Term . Have raised gale warnings along the coast and have expanded the area to include the bays for Tuesday into Wednesday. Gales may linger into Thursday for the outer waters. A couple gusts may reach storm force with 50 kt possible. Seas to build into the 15'+ plus range along the outer waters.

Long Term . Gale conditions to continue through Wednesday night in NE wind. Conditions trend to SCA Thursday evening with winds falling below 25 kt Thursday night. Waves will be slower to decrease from their high point Tuesday night. 4 to 6 ft waves could linger into Fri afternoon amid swell from exiting low pressure system.

HYDROLOGY. Locally heavy rain expected over southern areas, especially southeast New Hampshire Tuesday through Wednesday. A couple rivers may good into flood with some storm drainage issues as well.

TIDES/COASTAL FLOODING. Wave runup models indicate the possibility of splash-over along the coast beginning Tuesday night and continuing through Wednesday despite astronomically low tides. Large waves will combine with storm surge values approaching 3 feet over southern areas.

GYX WATCHES/WARNINGS/ADVISORIES. ME . None. NH . None. MARINE . Gale Warning from noon Tuesday to 6 PM EDT Wednesday for ANZ151-153. Gale Warning from 8 AM Tuesday to 11 AM EDT Thursday for ANZ150-152-154.
