Area Forecast Discussion National Weather Service Gray ME 313 PM EDT Sat Sep 25 2021

SYNOPSIS. The cold front will remain stalled to our east into tonight, and will bring some scattered showers to areas along the coast East of Portland. Another round of moderate to heavy rain is possible early Sunday into Sunday after noon mainly across SW and central Maine. Cooler, more seasonal are expected Monday through the middle of the week. There is a chance for scattered showers Monday and Tuesday as an upper low sits and spins jut to our north.

NEAR TERM /THROUGH TONIGHT/. A front remains draped across the eastern edge of the forecast area, with coastal York county, Cumberland, Androscoggin, Kennebec, and the midcoast remaining in a warm moist airmass. Dewpoints are in the 60s here with cloud cover. Meanwhile a completely different world across NH where skies are clear and dewpoints are in near 50. This dichotomy will continue through the next day or so as the front stalls, and even retrogrades slightly.

For the eastern areas, radar and satellite imagery show a band of showers developing along and just east of the surface boundary and these showers will move north and fill in bringing rain to Penobscot bay and points just west. While the individual cells are small they will continue to move along the frontal surface and this training presents a small threat for flash flooding through evening.

Now for something completely different; west of the front will remain dry with clear skies to start off overnight. These clear skies will allow temperatures to drop into the upper 40s with widespread fog once again forming in the river valleys.

SHORT TERM /SUNDAY THROUGH SUNDAY NIGHT/. Sunday a new player arrives to join our existing boundary. A short wave over the Great Lakes will approach from the west, and this interaction will pull the moisture back further west, backing right up into the White mountains. The CT river valley will likely still remain on the 'dry side' but overall expect coverage of showers to increase due to this interaction. Have kept the highest amounts from Portland east, where up to 2 inches is possible. However expect the drop off to nearly nothing to be quite abrupt and most of the area will see less than a quarter inch. This tight gradient is well represented in the HREF and HRRR forecasts and have leaned on those for the placement of the boundary.

Most of the rainfall will move through early Sunday morning, with the front starting to push out by mid day. By Sunday night the westerly flow aloft will finally kick out our lingering surface boundary and make way for the drier air to move in across the CWA. With so much moisture in place it'll take more than a single evening to dry out and thus fog is likely across the region on Sunday night.

LONG TERM /MONDAY THROUGH FRIDAY/. Latest models showing a little less amplifies 500 mb pattern across N Hemisphere for next week, but still with some significant blocking in place, and dominant Atlantic ridging. Still, downstream blocking over the N Atlantic and Rex block to our N extending to E of Hudson Bay will allow for 500 mb low to close off just to out N, and stay in the vicinity of the CWA through the week. Models have been fairly consitent with the forecast for the first half of the week, but change from run to run as to how that closed low interacts with energy coming in from the NW, and upstream and downstream blocking, so confidence beyond Tue begins dropping.

Mon/Tue will see that 500 mb close off to out N, allowing cooler air to work in, along with some clouds, especially in the mtns, and maybe a chance showers Monday afternoon/evening and Tuesday evening. Monday will see a sfc cold front work through, so this will be the better chance for showers across the nrn 2/3 of the CWA. Highs Monday range from 65-70 in the N to the low to mid 70s in the S. On Monday the cold front will have settle S of the mtns, but will likely still be crossing srn zones, so lows in the N will be in the mid 40s, but in the mid to upper 50s in the S. The from stalls a bit near S NH and the Me coast, and there may be a few showers here on Tuesday, and more in the way of clouds, with highs 60-65 in the N, and in the upper 60s to around 70 in the S.

For Wed/Thu and maybe into Fri, will be dealing with the closed low as it shifts S across the region, with cooler temps /maybe even a hair below normal for highs/, and the possibility of bouts of showers, but timing where and when at this point is really a game of chance. We'll call it unsettled, but not expecting any day would be a washout. Depending on where that closed low ends up could see ridging developing over the top of it and a warming trend for next weekend.


AVIATION /19Z SATURDAY THROUGH THURSDAY/. Short Term . The tale of two airmasses is most noticeable in the aviation impacts. The eastern portion of the CWA remains shrouded by clouds, as some locations struggle to even exceed MVFR ceilings. Meanwhile the western part of the CWA is clear with VFR conditions. Overnight will see flight category decreases across the area, but for opposing reasons. In the east, the clouds will slightly to mainly MVFR with scattered showers and even a rumble of thunder in heavy rain briefly resulting in IFR. Meanwhile across the western portion of the area, clear skies will give way to IFR and valley fog overnight.


Long Term . Mainly VFR in the extended from Monday through Thu. Will see some MVFR cigs in the mtns at times along with some showers. These are possible in the south as well es[especially Monday night.

MARINE. Short Term . Seas remain below 5ft currently with the font draped across the eastern portion of the waters, some chance for east of the front to see some 5footers, but with the boundary remaining along the CWA line have opted not to issue an SCA for the moment but will need to monitor the eastern waters overnight. Sunday the front will eventually sweep through the area with winds and seas remaining below SCA.

Long Term . Winds/seas stay mostly below SCA levels through Thursday.
