Area Forecast Discussion National Weather Service Gray ME 1059 PM EDT Thu Sep 23 2021

SYNOPSIS. Warm and humid conditions continue across the forecast area ahead of a cold front tonight through Saturday. This front will very slowly cross the region late Friday and Saturday with a period of widespread rainfall likely, along with a few thunderstorms. Improving conditions are expected by the second half of the weekend as drier air arrives from the west. A cold front will then approach the region early next week with another threat for showers.

NEAR TERM /UNTIL 6 AM FRIDAY MORNING/. 1045 PM Update . Have adjusted pops upwards over eastern areas as showers continue to spread into the region from off the Gulf of Maine. Made some minor adjustments to temperatures, dew points and winds based on current conditions and near term forecasts. Have aligned the timing of the main band of precipitation to enter southwestern New hampshire early tomorrow morning in line with the latest HRRR.

Prev Disc . 815 PM Update . Pushed the onset of fog back to after midnight based on satellite imagery and surface observations. Although some low stratus is beginning to form along portions of the Mid-Coast and Downeast Maine, surface observations have yet to indicate any reductions in visibility. Other than a stray sprinkle, radar is still rather quiet across the area with the widespread showers and thunderstorms still located well to our west across NY state. As a result, PoPs were also adjusted in order to push back the onset of measurable rainfall. Other than some minor adjustments to temperatures and sky cover, the rest of the forecast remains on track.

Previously . Scattered showers will continue from time to time across mainly the higher terrain and parts of New Hampshire this afternoon before a lull in activity this evening. The chances for precipitation gradually increase from west to east overnight tonight as the cold front slowly approaches the area. South and southeast facing terrain will again see enhanced shower activity as the front approaches. A moisture rich airmass will continue to push into northern New England with PWAT values near 2 inches, along with dew points pushing into the upper 60s. This is likely to lead to patchy fog overnight, while the high PWAT values set will aide in bringing a widespread soaking rainfall to the area.

SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/. The front will be very slow to move eastward, so eastern zones will have to wait until late in the afternoon for the steadiest and heaviest rain to arrive. Most of the the rainfall will occur within a narrow band along the front, and a few strong thunderstorms are possible with the daytime heating across new Hampshire and western Maine. Overall the severe threat looks limited by the lack of widespread sunshine any and marine influence, but with the moist airmass, low LCLs, and moderate shear values a few strong storms can't be ruled out.

Overall there is a threat of some heavy rainfall from heavier or training storms, so that will need to be monitored closely tomorrow. The highest rainfall amounts look to be across the southeast facing slopes, as well as the MidCoast and Central Maine where 2-3in of rain are possible. The MidCoast may still see another push of moisture on Saturday, but just how much falls within our CWA is still somewhat unclear, but the potential is there for higher rainfall amounts.

LONG TERM /SATURDAY THROUGH THURSDAY/. The weekend will start off with a trough over the Great Lakes keeping us on the warm side. By Sunday that upper level low will move overhead, and linger through the start of next week. Some hint a the progression of the flow allowing an upper level ridge into the region by mid next week but a lot so spread in that amongst the guidance and with block season starting an always hesitant to be too proactive with moving system's through.

Saturday will be dominated by the exiting cold front. By 12Z we'll have the front still likely draped through eastern portion of the forecast area. To the west, while the FROPA has occurred expect valley fog to remain in the CT river as the full mixing won't have been able to get the moisture out overnight. That mixing will be the job of Saturday as the west flow and increasing sunshine allows for decreasing dewpoints.

Saturday night some fog is still possible, especially in the northern moutnains where upslope flow will help to hold low clouds and even a few showers in the region. This will keep the lows slightly warmer than otherwise although still colder than we've seen the past few days.

On Sunday the upper low lingers, and that will allow a short wave to drop south out of Ontario, touching off another round of showers. With southerly flow on the east side of the upper level trough still dominating, that will help to focus another round of much needed upslope rain into the western Maine mountains. Still quite a bit of spread in the ensembles but starting to focus in on this Sunday event actually having slightly more QPF than Friday in the mountains.

Monday into Tuesday with the upper low lingering we see a series of upslope showers and some possible weak short waves. Here there's a lot of spread mainly in the timing of the smaller waves and the result is just a widespread low PoP throughout the period.

AVIATION /03Z FRIDAY THROUGH TUESDAY/. Short Term . Areas of fog and low ceilings will bring IFR to LIFR conditions to most terminals tonight, and possibly again tomorrow night. Showers will also bring restrictions late tonight across western terminals, and by late tomorrow afternoon across eastern terminals.

Long Term . Another round of rain will bring MVFR and IFR for Sunday into Monday.

MARINE. Short Term . Freshening winds will bring SCA conditions late tonight through Saturday morning, with seas of 4-6ft and southerly gusts up to 30kts. Winds will become westerly behind a passing cold front on Saturday and ease.

Long Term . Winds and seas will remain below SCA through next week.

GYX WATCHES/WARNINGS/ADVISORIES. ME . None. NH . None. MARINE . Small Craft Advisory from 5 AM Friday to 8 AM EDT Saturday for ANZ150>154.
