Area Forecast Discussion National Weather Service Caribou ME 509 PM EDT MON JUL 4 2016 .SYNOPSIS... A cold front will cross the region later Tuesday and stall. The front will return northward as a warm front later Wednesday. && .NEAR TERM /THROUGH TUESDAY/... 5:09 PM Update...Thunderstorms are holding together as they move across the Saint lawrence River. Will add in the mention of isolated thunderstorm this evening across the Saint John Valley and Allagash. will also mention gusty wind with the thunderstorms due to fairly dry low levels below 800 Otherwise, no significant changes at this time. Previous discussion... High pressure to the south of New England will dominate tonight into Tuesday Morning. Expect partly cloudy conditions to give way to clear skies later this evening as day time heating subsides. Later in the day Tuesday an upper level trough will pass to the north of the State. This system may result in showers and Scattered Thunderstorms during the afternoon. && .SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/... A weak upper level trough will cut across northeast Maine on Wednesday brining a chance of showers to mainly the crown of the state. Flat ridging will likely bring a very brief respite from unsettled weather Wednesday evening before the next shortwave trough and associated surface low approach from Quebec. Late Wednesday Night into Thursday looks damp and unseasonably cool across northern Maine with periods of rain. QPF totals of between one half to one inch are possible with this system. && .LONG TERM /THURSDAY NIGHT THROUGH MONDAY/... Unsettled weather will affect the area through the early portions of the extended forecast. A weak frontal boundary will remain across the region at the start of the period. The front will move east into New Brunswick early Fri mrng, and higher pressure will build into the area. The high will move east of the area Fri evng as another frontal system moves into wrn Maine. Early Sat mrng a warm front will move into central Maine, then the cold front will follow Sat evng. The cold front will move into New Brunswick early Sun mrng, with some clearly in srn Maine overnight. The low associated with this system will be over srn Quebec. The GFS show the low with a closed co-located upper low, the ECMWF show the low with a 500 hpa trough supporting the low. These differences will determine how quickly the surface low track across nrn Maine through the end of the period. The GFS solution will keep nrn and central Maine under the influence of the upper low and its associated trough as it slowly moves through until the end of the period. The ECMWF moves the upper trough through Maine Sun evng, with higher pressure building in behind the front. Loaded a blend to smooth out the minor differences in the models. The blend splits the differences between the GFS and ECMWF . Loaded NAWAVE4 for seas in the coastal waters. Loaded windgust by factor tool. | && .AVIATION /21Z MONDAY THROUGH SATURDAY/... NEAR TERM: Expect VFR conditions tonight and Tuesday. Isolated t-storms are possible this evening at KFVE with locally gusty wind and briefly lower ceilings. MVFR conditions are possible Tue afternoon in north during showers. SHORT TERM: MVFR cigs and vsbys are forecast primarily across northern TAF sites Wednesday Night into Thursday in periods of rain. && .MARINE... NEAR TERM: Have used the NAM12 to initialize the sustained winds. Cold sea surface temperature (54F) continues to keep strong south to southwest winds aloft from reaching the surface due to a resulting inversion. So have reduced the forecast model wind speed by 20 percent. For waves: Have initialized the wave heights using the NWPS model to take advantage of forecaster generated wind speed, however cold sea surface induced inversion extends beyond the NWPS boundary so will further reduce model wave heights by 1 foot. There is currently no secondary long period wave system entering the local waters. SHORT TERM: No headlines are forecast during this time period. && .CLIMATE...Today was the 12th day this year with a high temperature of 80 degrees or warmer at Caribou. On average, by July 4th there would be 7 days with a high of 80F or warmer. && .CAR WATCHES/WARNINGS/ADVISORIES... ME...None.
