825 FXUS61 KGYX 311118 AAA AFDGYX Area Forecast Discussion...UPDATED National Weather Service Gray ME 718 AM EDT Fri May 31 2024 .SYNOPSIS... High pressure will make for warm and mostly dry days in the short term with breezy northwesterly winds. A few light showers will be possible today in east-central ME but amounts will be minimal at best. A warming trend will begin this weekend with any chances for showers remaining minimal. These mild and generally dry conditions are expected to persist through at least the first half of next week. && .NEAR TERM /UNTIL 6 PM THIS EVENING/...

720 AM Update...Quick update to drop the frost advisories as temperatures round the bend and begin quickly rising this morning. No other changes attm. 610 AM Update...No changes to the going forecast other than some minor adjustments to sky cover and temperatures early this morning. Previously... A weak pressure trough will move across the forecast area as an upper level trough also moves eastward overhead. The net result will be little in the way of fanfare, other than a period of BKN clouds this afternoon with a chance of showers in our far eastern zones. Otherwise, a warm and breezy day is expected for all of our area. Strong enough opposing flow will likely allow for the seabreeze to remain offshore except perhaps the peninsulas and islands this afternoon.

&& .SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/... Another mostly clear night is expected tonight with light winds. Pockets of radiational cooling are expected, especially in the far interior, but temperatures should be just high enough to preclude anything more than patchy frost. Utilized a blend of MOS guidance for tonight. Sunny skies with a northwest breeze expected on Saturday. With high pressure moving into the Gulf of Maine we expect a cooler onshore flow to develop on the coast by late afternoon. Otherwise, highs look to be well into the 70s most locations. && .LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/... A rather quiet weather pattern in the long term with moderating temperatures. Next chance of widespread showers will hold off until late next week. In the dailies: On Sunday a weak warm front will lift north. This may bring a period of mid to upper level clouds but moisture appears to be limited. High pressure establishes itself overhead Monday and Tuesday. The high pushes offshore on Wednesday as low pressure moves to the Western Great Lakes. As that low moves into Southern Canada on Thursday, a cold front will pivot around the low and approach the region during the day. This will result in an area of showers and possible thunderstorms later in the day and beyond. Have added patchy marine fog each night starting Monday Night. High temperatures will range from the 70`s to lower 80`s with seabreezes cooling immediate coastal areas and islands. Low temperatures will moderate from the upper 40s to low 50s Sunday morning to the mid 50s to around 60 by Thursday morning. && .AVIATION /11Z FRIDAY THROUGH TUESDAY/... Short Term...VFR across the terminals this early Friday morning and this will dominate the period through Saturday. There is some limited potential for some fog at HIE early this morning...but confidence in occurrence is not high enough at this time for inclusion in the 06z TAF. NW winds gusting up to 20 MPH at times should keep the seabreeze offshore, but it will probably hug the islands and peninsulas. A more pronounced seabreeze is expected later Saturday afternoon as high pressure moves offshore. Long Term... Expect VFR to MVFR throughout the period. && .MARINE... Short Term...Northwesterly winds 10 to 15 kts through the period will allow both winds and waves to remain below SCA levels through Saturday. Long Term...Wind and waves to remain below SCA conditions through the extended forecast period. Patchy fog mainly at night starting Monday Night. && .FIRE WEATHER... Both today and Saturday will feature gusty northwesterly winds 15 to 25 MPH with afternoon RH values dropping to between 20 to 35 percent away from the immediate coast. Despite full green-up, some leftover 1 hour fuels could start to burn and spread. && .GYX WATCHES/WARNINGS/ADVISORIES...
