279 FXUS61 KGYX 251020 AAA AFDGYX Area Forecast Discussion...UPDATED National Weather Service Gray ME 620 AM EDT SAT JUN 25 2016 .SYNOPSIS... High pressure remains in control over the weekend before moving offshore later in the the weekend and early next week. This will allow a more humid air mass to move into the region. A slow moving cold front approaching from the west brings a chance of showers and thunderstorms Tuesday, Wednesday and into early Thursday. The front will exit the region by late Thursday. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... 620 AM Update... A few cirrus clouds are crossing the area this morning. That as well as some spots of fog in the CT river valley is about all that is going on this morning. Temperatures are in the 40s and 50s and will warm up into the 70s and 80s today. Previous Discussion... High pressure remains in control at the surface and aloft delivering another beautiful sunny and mostly-cloud-free day. By midday dew points will be about 10 degrees higher than they were 24 hours ago indicating southerly winds are transporting moisture- rich air into the area. There is a small chance of showers mainly over the North Conway/Mt Washington environ as a short wave passes by overhead. Temperatures will reach the upper 70s to mid 80s with warmer temperatures even reaching the mountains today. A sea breeze will keep temperatures along the coast just a few degrees cooler. && .SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SUNDAY/... Tonight readings will drop into the 50s areawide under light winds and mostly clear skies. This will allow for fog to form in valleys and other favored region similar to previous nights. We are expecting an even warmer day Sunday with mid to upper 80s in quite a few locations. Once again high pressure off shore will produce conditions ripe for a sea breeze which will penetrate inland a ways and keep highs a bit cooler along the coast. && .LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/... A warm south to southwest flow will continue Sun night into Tue ahead of an approaching trough and associated surface cold front. Temperatures will continue mild and become humid ahead of the system. By Mon night showers and thunderstorms will begin to move across the area ahead of the system. The surface cold frontal passage will occur late Tue or Tue night. On Tue and Tue night showers and thunderstorms are expected bringing some much needed rain. The front moves off the coast by early Wed but a lingering upper trough will produce some lingering showers Wed into Thu. By late Thu and Fri a return to dry and relatively mild weather can be expected as high pressure builds east. Generally accepted the superblend guidance for this outlook period. && .AVIATION /10Z SATURDAY THROUGH WEDNESDAY/... Short Term...VFR conditions through Sunday will prevail. However patchy MVFR restrictions in valley fog are possible late tonight and again Sunday night, mainly at LEB and HIE. A sea breeze is likely Saturday and Sunday afternoons. Long Term...VFR through Monday. MVFR to IFR conditions in showers/thunderstorms Mon night into Wed. && .MARINE...
