871 FXUS61 KGYX 110621 AFDGYX Area Forecast Discussion National Weather Service Gray ME 221 AM EDT Sun Aug 11 2024 .SYNOPSIS... Relatively quiet weather expected today and into next week as the region resides between systems. Low pressure passes through northern New England Monday, with surface high pressure nearing the region by mid week. These will bring scattered showers through the week, but only few chances for wetting rainfall. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... Cooler weather is expected today as a new air mass pushes in from the west. However, a short wave trough approaching from the west will offshore a few showers in the mountains this afternoon as forcing for ascent increases and heating allows for weak instability. An isolated thunderstorm is possible as well. Most of the forecast area will remain dry with highs 2 or 3 degrees of 80F depending on location. && .SHORT TERM /6 PM THIS EVENING THROUGH 6 PM MONDAY/... One short wave trough moves through tonight with a few showers possible, mostly in the mountains. A mid and upper level trough will move across New England on Monday with showers likely in the mountains with lesser chances the farther south one goes. An afternoon thunderstorm not out of the question. Highs mainly in the 70s. && .LONG TERM /MONDAY NIGHT THROUGH SATURDAY/... Upper low will continue to push into central Maine Mon night, lifting into the Canadian Maritimes Tuesday. This brings a less favorable environment for shower potential Tuesday, but remains a slight chance of showers amid NW winds behind. Towards midweek, surface high pressure will advance east while broad area of low pressure resides aloft. This could bring the chance for daily showers or sprinkles, but dry air at the surface will mitigate how widespread these are. With wide dew point depressions at the surface, humidity should be lower for midweek with temperatures continuing around normal. && .AVIATION /06Z SUNDAY THROUGH THURSDAY/... Short Term...VFR will be the prevailing condition through today. A few showers or a thunderstorm is possible this afternoon or early this evening in the vicinity of AUG and RKD, and then again Monday afternoon and evening. Winds are expected to remain less than 15 knots. Long Term...Most terminals remain VFR through the period. Restriction concerns are focused on HIE/LEB where ceilings or fog may cause IFR restrictions at night. && .MARINE... Short Term...Conditions will then remain below SCA criteria through Sunday. Winds will be generally westerly with gusts 10-20 kts. Long Term...Conditions below SCA through mid week. Low pressure will pass inland and towards the Canadian Maritimes Monday, with high pressure nearing the coastal waters through mid week. && .GYX WATCHES/WARNINGS/ADVISORIES... ME...None. NH...None. MARINE...None. && $$ NEAR TERM...Ekster SHORT TERM...Ekster LONG TERM...Cornwell/Ekster
