Area Forecast Discussion National Weather Service Gray ME 334 PM EDT Thu Oct 1 2020

SYNOPSIS. Fair weather will give way to a low pressure system and a chance for more beneficial rainfall Friday. Besides periods of cloudy skies over the weekend, the weather looks to be fair with seasonable temperatures. Another chance of rain looks to arrive early next week as low pressure passes off the Mid Atlantic coast and moves northeastward. However, it could also remain far enough south to keep our area dry.

NEAR TERM /UNTIL 6 AM FRIDAY MORNING/. An upper level trough will approach from the west tonight. Partly cloudy conditions will give way to increasing cloudiness late at night as moisture spreads east. Before the cloud deck moves in, patchy fog may develop across some of the interior valleys.

Overnight lows will fall into the 40s in most sections. However, right along the immediate coastline, some lower 50s can be expected.

SHORT TERM /6 AM FRIDAY MORNING THROUGH 6 PM FRIDAY/. 12Z model suite in relatively good agreement indicating that the upper level trough will allow for the development of a weak low pressure system over our coastal waters. This type of track will keep most of the expected rainfall to northern areas with less towards the coastline. A short wave tracking through northern New Hampshire and Maine will accentuate the precipitation across the mountains.

Over the highest peaks, some light, accumulating snowfall may possibly mix in with the rain at Mount Washington.

The precipitation will be followed by high pressure build into New England from southern Canada. Clearing skies, light winds and chilly temperatures will allow for patchy late night fog to develop. Most likely areas for fog will once again be the interior valleys.

LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/. For the extended portion of the forecast, we will initially remain in or near the dominant trough affecting the central and eastern CONUS. We will be caught in the SW flow/exit region of the upper jet on the frontside of the trough over the weekend. This will allow weak forcing for ascent to pass over the area, producing a shower from time to time over the mountains Saturday. Sunday looks dry with weak high pressure at the surface.

Precipitation chances increase on Monday as low pressure moves southwest of Cape Cod and an inverted trough nears northern New England. Southern sections of NH and coastal ME will have the best chance for some light rain before it comes to an end Monday night, but in general the bulk of the rainfall will be to the south and offshore. QPF amounts look to be less than a quarter inch for the immediate coast.

High pressure builds in briefly Tuesday before a weak trough moves into northern New England. A more organized area of low pressure will deepen near the CT River Valley around midweek. There seems to be fair agreement among the models that we will receive widespread rain from this system,and have increased PoPs somewhat. That said, did not go too high because it is still a long way out and though a dominant short wave will swing through the northeast, it is still undetermined as to its exact location and strength.

Temperatures will hover in the low to mid 50s north, and into the mid to upper 60s closer to the coast and over southern NH.

AVIATION /19Z THURSDAY THROUGH TUESDAY/. Short Term . Localized IFR conditions in patchy late night fog across interior valleys expected tonight and again Friday night. Otherwise VFR conditions expected.

Long Term . VFR expected for the weekend, with an isolated mountain shower/MVFR ceilings possible at KHIE Saturday. MVFR conditions likely Monday in showers. VFR will prevail Tuesday.

MARINE. Short Term . Have extended the SCAs for seas through this evening. Seas will gradually subside thereafter.

Long Term . Quite on the waters Saturday through Tuesday. On Wednesday, an increasing southerly flow will likely cause winds and seas to reach Small Craft criteria, especially over the outer waters.

GYX WATCHES/WARNINGS/ADVISORIES. ME . None. NH . None. MARINE . Small Craft Advisory until 11 PM EDT this evening for ANZ150- 152-154.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
