NWS Gray, ME wrote its last area forecast discussion before the first event at Aug 28, 6:36 PM EST, 14 minutes earlier.
Area Forecast Discussion National Weather Service Gray ME 736 PM EDT SUN AUG 28 2016 .SYNOPSIS... A cold front will approach Maine and New Hampshire tonight and move off the coast early monday morning. High pressure will build over the region Monday and move of the coast Tuesday. Another cold front will cross the area Wednesday. Cool high pressure will build in over the remainder of the week. && .NEAR TERM /UNTIL 6 AM MONDAY MORNING/... 730 pm update: Showers and thunderstorms now moving into Northern NH and Western ME with the heaviest cells moving into southern Coos County. Have increase pops for northern areas and kept the enhanced wording for northern areas into the evening. Have input latest obs data and made some minor adjustments to temperatures. 525 pm update: A broad area of showers and thunderstorms have developed and moved across far northern Vermont and will be moving into northern NH in the next hour or two. Have raised pops across northern areas of NH and western ME to account for this well developed area. Have put some enhanced wording across these areas just into the early evening. No other changes at this time. Previous Discussion: Bona fide convection now moving into Vermont associated with a frontal system. We have seen some echoes in our area but still don't think anything has reached the ground. However the atmospheric column is apparently saturated enough across the far north for rain to reach the ground. Dew points elsewhere are still in the 50s with temperatures in the 70s and 80s. PoPs are mainly confined to the higher terrain this afternoon and overnight with a few sprinkles possible as far south as Lebanon with the cold front. Also we may see something reach the mid coast along the warm front...but in between there is not much hope for measurable precipitation. Isolated to scattered thunderstorms are possible as the better forcing arrives later tonight into the overnight hours but no hazardous weather besides lightning is expected. Storm total QPF values- where it does rain- will range between 0.20" to 0.40". The front moves offshore quickly tomorrow morning with clouds disappearing quickly across the interior and coast. Across the mountains some clouds will linger in upslope flow. Expecting gusty winds up to 25 mph. Temperatures will warm into the 80s across the south with locations closer to the Canadian border struggling to get out of the 60s.SYNOPSIS... && .SHORT TERM /6 AM MONDAY MORNING THROUGH MONDAY NIGHT/... High pressure builds across the areas on west winds with a drier and cooler air mass. && .LONG TERM /TUESDAY THROUGH SUNDAY/... High pressure over the region Tuesday should provide a mostly sunny day with comfortable humidities and high temperatures from the mid 70s to lower 80s. As the high slips offshore Tuesday night...a cold front will approach the area...and then cross the area Wednesday. Like many recent frontal passages any showers and possible thunderstorms will be scattered...with the greatest chance for rain in the mountains. A cool Canadian high pressure system will follow the front for Thursday and Friday. An upper level trough will swing through the area Friday. At this time, this feature looks dry...but it could kick off a shower in the mountains. Dry weather is currently expected over the holiday weekend with temperatures gradually warming. && .AVIATION /00Z MONDAY THROUGH FRIDAY/... Short Term...A cold front will approach from the west tonight. Widely scattered SHRA or TSRA could lead to MVFR or lower conditions...especially across the CT River Valley. SHRA or an isolated TSRA will sweep across the forecast area with the front...with areas of MVFR and maybe local IFR in heavier convection. Dense fog and stratus is likely for AUG...LEB...and HIE. Coastal fog and stratus are likely for the mid coast and but should stay east of Portland. Gusty west winds around 20 kts Monday will clear things back out to VFR...except at HIE where upslope clouds may keep some near MVFR CIGs. Another round of fog is expected Monday night into Tuesday morning with radiational cooling allowing temperatures to drop close to dew points. Long Term... Mainly VFR conditions expected through the period except for MVFR conditions possible in scattered showers and possible thunderstorms Wednesday. && .MARINE... Short Term...Coastal fog/stratus will form by tonight. Seas and winds increase tonight into tomorrow to 5-6 ft with a few wind gusts to 25 kts. Waves will be a combination of swell from Gaston and winds associated with a cold front. Long Term... Offshore seas will be near SCA criteria through Wednesday...then expected to be below sca criteria Thursday and Friday. && .GYX WATCHES/WARNINGS/ADVISORIES... ME...None. NH...None. MARINE...Small Craft Advisory until 8 AM EDT Tuesday for ANZ150>154. &&
