050 FXUS61 KGYX 010719 AFDGYX Area Forecast Discussion National Weather Service Gray ME 319 AM EDT FRI JUL 1 2016 .SYNOPSIS... A cold front will approach from the west today and will cross the region overnight. A trough of low pressure will linger over the region Saturday and Sunday. High pressure will build in from the west Sunday night through Tuesday and will shift offshore on Wednesday. && .NEAR TERM /THROUGH TODAY/... Cold front will approach from the west today as a strong shortwave shifts east from the great lakes. Timing of the front will preclude any severe storms in the forecast area as sufficient moisture and instability won`t make it into western zones until late this afternoon and early this evening past the time of max heating. Will likely see remnants of stronger convection to the west getting into the connecticut valley by mid afternoon and spreading eastward across New Hampshire through early evening. Brisk onshore flow will contribute to a robust marine layer in southern Maine and southeast New Hampshire so expect convection to diminish as it pushes into these areas during the late afternoon and evening. Mountains and foothills of Maine will likely see enough moisture and instability to get in on some spotty thunderstorm activity during the late afternoon and evening. High temps will be similar to Thursdays with most areas reaching the lower to mid 80s. && .SHORT TERM /TONIGHT THROUGH 6 PM SATURDAY/... Showers and thunderstorms will gradually push east of the forecast area after midnight as the front slowly crosses the area. Behind the front...westerly flow will bring clearing to the region toward daybreak. Should see a fairly mild night with lows generally in the mid 50s north to lower 60s south. Saturday will feature a mix of sun and clouds in the mountains and mostly sunny skies elsewhere as cooler and less humid air flows into the region on increasing westerly winds. Highs will range from the mid 60s to mid 70s north and upper 70s to lower 80s south. && .LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/... Fairly decent weather with mostly dry conditions in the long term and increasing warmth. For Saturday night and Sunday expect temperatures to be running cooler than normal. Can`t rule out an isolated shower in the mountains Sunday afternoon. Temperatures begin to warm Monday and by midweek the 500 ridge moves in with temperatures rising into the mid and upper 80s in southern New Hampshire and lower to mid 80s in southern Maine. A seabreeze will develop keeping coastal communities a bit cooler. && .AVIATION /07Z FRIDAY THROUGH TUESDAY/... Short Term...VFR today with areas of MVFR ceilings and vsby in afternoon thunderstorms across New Hampshire. Areas of IFR/LIFR ceilings/vsby overnight...especiallly in coastal and southern interior Maine. VFR saturday. Long Term... Expect VFR through the period. && .MARINE... Short Term...No flags. Long Term...Expect winds and seas to remain below SCA criteria. && .GYX WATCHES/WARNINGS/ADVISORIES... ME...None. NH...None. MARINE...None. && $$
