934 FXUS61 KGYX 111939 AFDGYX Area Forecast Discussion National Weather Service Gray ME 339 PM EDT Wed Jun 11 2025 .SYNOPSIS... Mostly dry and breezy weather will prevail through Thursday. High pressure will build in from the north Friday for fair weather. A frontal zone will provide a focus for clouds and showers Saturday into Sunday. High pressure builds back into the region Monday before shifting offshore towards the middle of next week. && .NEAR TERM /THROUGH TONIGHT/... Pleasant conditions will continue this afternoon with comfortable dewpoints and temperatures mostly in the 70s to low 80s. We`ve had enough low- level moisture/instability for a cumulus field to develop with occasion mostly skies, but these will dissipate toward sunset. Still can`t rule out a couple of brief showers this afternoon, but very dry air aloft and subsidence aloft will make these hard to come by. A cold front approaches and moves through tonight and may produce some showers in the mountains and generally just a modest and brief increase in cloud cover elsewhere. Low temperatures will range from the mid 50s to low 60s. && .SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/... Behind the front, the airmass will remain warm and dry for Thursday. Good mixing will bring higher winds down from aloft with gusts 25-35 mph in the morning and afternoon while also supporting highs reaching the upper to low-mid 80s. Similar to today, there will be enough low-level moisture for a cu field to develop, but I think it will be a bit more sparse that today. Above the cloud layer, forecast soundings continue to show very dry air with the subsidence inversion even more pronounced. So I think showers will struggle even more than today, although upsloping in the mountains could still result in a few showers there The cu field will dissipate around sunset with the loss of heating, and winds will also start to come down. Quite weather continues Thursday night with low temperatures in the 50s for southern areas with 40s possible from the foothills northward. && .LONG TERM /FRIDAY THROUGH WEDNESDAY/... The 500 mb flow pattern will turn close to zonal across the northern tier of the CONUS this weekend into early next week. At the surface, high pressure will be centered south of Hudson Bay Friday through the weekend with a west to east frontal zone setting up across the Great Lakes and Northeast. Moisture from a weak wave crossing the Ohio Valley will interact with this frontal zone this weekend bringing chances for showers. Shower chances diminish Sunday into Monday as high pressure slides over New England. High pressure then shifts east through mid week leading to an upward trend in temperatures and humidity. High pressure centered south of Hudson Bay will extend into the forecast area Friday providing fair weather. Light northwest flow will prevail over the area except for a sea breeze developing along the coast during the afternoon. Highs will range from the 60s north to upper 70s across the south. High pressure holds over southeast Canada Saturday while an open wave over the Ohio Valley advects warm air and moisture northward. This set up will produce a west to east baroclinic zone with waves of low pressure bringing chances for showers Saturday into Sunday. Ensembles generally agree that shower chances will be likely Saturday while amounts will be light with mean QPF around 0.5 inches. Ensembles then suggest drier air will work in from the north Sunday that will allow PoPs to decrease into Sunday night. Mostly cloudy skies and east winds will keep things cool over the weekend with highs mainly in the 60s. High pressure slides southeast and crests over the region Monday for a return to mostly fair weather. This high will then slide offshore towards mid week with return flow advecting warmer air and moisture into the region. With little in the way of surface features and upper level support chances for showers will be low Tuesday into Wednesday. && .AVIATION /19Z WEDNESDAY THROUGH MONDAY/... Short Term...VFR with very low shower chances this afternoon with occasional BKN060-BKN080. Clouds diminish this evening and then increase somewhat again tonight as a cold front approaches and crosses. This may bring a brief period of MVFR ceilings and/or showers toward HIE. VFR Thursday W/WNW winds gusting as high as 25 to 30 kt with and maybe a shower or two toward HIE. These diminish Thursday and evening and night with VFR prevailing. Long Term...Mainly VFR Friday into Friday night. More in the way of clouds and -SHRA are likely Saturday into Sunday with periods of at least MVFR possible. Drier air works into the region late Sunday into Monday for a return to VFR. && .MARINE... Short Term...A tightening pressure gradient will result in increasing southwest winds across the waters through tonight as a cold front approaches and crosses by Thursday morning. This could lead to marginal SCA conditions with seas building up to 5 ft. Winds may continue to gust to around 25 kt at times on Thursday before diminishing Thursday evening and night. Long Term...Winds and seas remain below SCA thresholds Friday into early next week. Light offshore winds will turn onshore Friday. A front stalling near the waters will bring periods of showers and steady easterly flow over the weekend. && .GYX WATCHES/WARNINGS/ADVISORIES... ME...None. NH...None. MARINE...Small Craft Advisory until 8 AM EDT Thursday for ANZ150-152. && $$ NEAR TERM...Combs SHORT TERM...Combs LONG TERM...Schroeter
