000 FXUS61 KCAR 260452 AFDCAR Area Forecast Discussion National Weather Service Caribou ME 1252 AM EDT FRI AUG 26 2016 .SYNOPSIS... High pressure will remain southeast of the region overnight. A cold front will cross the region Friday afternoon. High pressure will build across the region Saturday then move to the east Sunday. Another cold front will approach the area Sunday night. && .NEAR TERM /THROUGH TODAY/... Update... An upper level disturbance will cross the region overnight in advance of an approaching cold front. Expect mostly cloudy skies along with scattered showers across the forecast area overnight. Will also have patchy fog overnight. Overnight low temperatures will generally range from the mid to upper 60s across the forecast area. Have updated the forecast to adjust for current conditions along with overnight temperatures, shower chances and cloud cover. Previous discussion... Front wl rmn north of CWA tonight bfr finally being shoved south Fri morning as H5 wv currently dropping thru wrn Ontario drives a sfc low into Newfoundland, propelling it south. Front progged to mv thru the area drg the aftn with plenty of instability but little moisture to work with. Hv opted to go with 20-40 pops along the front tomorrow and isold thunder. && .SHORT TERM /TONIGHT THROUGH SUNDAY/... The cold front will exit the Down East region Friday evening with lower humidity working its way southward through the night. Some patchy fog is possible along the coast early in the evening. Will go for a mostly sunny day on Saturday. The only concern would be some stratocu fields in Aroostook County in the NW flow. Highs on Saturday will be in the mid 70s north and upper 70s to lower 80s for Bangor and Down East. Humidity will be much lower on Saturday and continue to be reasonable on Sunday. Expect a relatively cool night Saturday night with lows in the upper 40s north and low to mid 50s south. Would go for lower temps, but am concerned about increasing cirrus later in the night ahead of the next system. The next system has sped up in the latest guidance packages and have introduced chance pops in the northwestern portion of the forecast area for the afternoon. Also increased cloud cover for most of the area Sunday to the extent that mostly cloudy skies are now forecast in northern zones. && .LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/... The frontal system for Sunday night and Monday morning looks a little stronger than previously with a reasonable chance of rainfall totaling a quarter to a half inch for much of the area. Most of the precip will occur Sunday night and the cold front will ease through the area Monday with some additional shower activity. It is possible a few thunderstorms could occur Monday afternoon, but confidence is not high enough to specify them in the forecast at this time. High pressure and lower humidity return to the forecast Monday night into Tuesday night. A weak cold front will arrive Wednesday morning with little precipitation, but a good chance of more fall-like temps and humidity for Wednesday night into Thursday. && .AVIATION /04Z FRIDAY THROUGH TUESDAY/... NEAR TERM: Expect conditions to generally lower to MVFR levels across the region overnight, with locally worse conditions in any patchy fog. Conditions should generally improve to VFR levels later Friday morning. However, variable conditions could occur with any showers/thunderstorms. SHORT TERM: VFR through Sunday evening with the exception of patchy shallow fog in valleys later Saturday night. IFR cigs in rain are expected Sunday night into Monday morning. && .MARINE... NEAR TERM: A Small Craft Advisory for hazardous seas remains in effect for much of the waters, with the exception of the intracoastal waters, overnight into Friday afternoon. Visibilities will be reduced in areas of fog and showers overnight into Friday, could also have an isolated thunderstorm Friday afternoon. SHORT TERM: Fog is expected to linger into Friday evening before dissipating. Some areas of fog may return Sunday night. Seas may approach 5 ft later Monday. && .CAR WATCHES/WARNINGS/ADVISORIES...
