396 FXUS61 KCAR 261030 AFDCAR Area Forecast Discussion National Weather Service Caribou ME 630 AM EDT Wed Jul 26 2017 .SYNOPSIS... High pressure will build across the region today. A cold front will cross the region later Thursday through Thursday night. && .NEAR TERM /THROUGH TONIGHT/...
-- Changed Discussion --
630 AM update...No changes needed with this update. Seeing a bit of patchy fog in some of the river valleys this morning, but this will burn off quickly over the next hour. Previous discussion...Sunny and mild weather expected today as high pressure slowly builds across the region. Highs will mainly be n the upper 70s to lower 80s, though as usual, the immediate coast will be cooler owing to onshore flow. The high moves offshore tonight, making way for a cold front sinking southward from Quebec. Showers associated with this boundary will move into far northwestern Maine after midnight and push south and east through daybreak Thursday. Increasing moisture ahead of the front will keep overnight lows in the mid to upper 50s in most locations, with some locations possibly staying in the lower 60s. This moisture will also allow some patchy fog to develop late tonight across Downeast areas.

&& .SHORT TERM /THURSDAY THROUGH FRIDAY/... A cold front will cross the region Thursday accompanied by showers and the chance of a few thunderstorms, mainly across northern and western areas. For now, have decided against enhanced wording at this time. SB Cape forecast less than 1000J and lapse rates not all that impressive. The cold front will move east of the forecast area later Thursday night with any lingering showers ending Thursday evening. High pressure will build in on Friday with partly to mostly sunny skies expected. High temperatures on Thursday will range from the upper 60s to lower 70s but cooler along the coast. Highs on Friday will range from the low to mid 70s but again cooler along the coast. && .LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/... Looks like a decent stretch of weather coming up for the weekend. The only fly in the ointment will be low pressure moving northeast from the mid atlantic region Friday night and Saturday. The overall consensus of model solutions keeps the low well to the south of Nova Scotia, leaving the forecast area high and dry this weekend. However, the 00z operational GFS was further north and tracks the low across southern Nova Scotia, keeping down east on the northwest fringes of the rain shield associated with the system. A couple of fronts may affect the region early next week. High temperatures this weekend through early next week are expected to be near to a bit above normal. && .AVIATION /12Z WEDNESDAY THROUGH SUNDAY/... NEAR TERM: Outside of some patchy fog, expect VFR conditions to prevail through 03z Thu. Showers will move into the northern terminals thereafter, with MVFR possible. Patchy fog will develop Downeast after 06z Thu, producing local MVFR/IFR conditions at BHB and perhaps BGR. SHORT TERM: Showers are expected to accompany the passage of a cold front Thursday with a chance of a thunderstorm across western areas. MVFR conditions will be possible in any showers otherwise VFR expected. VFR expected Friday through Sunday. && .MARINE... NEAR TERM: No headlines are expected through the next 24 hours. High pressure will build across the waters today and tonight, keeping conditions fairly quiet. Winds and seas will increase a bit tonight as a cold front draws closer from the north, but both parameters will remain below Small Craft Advisory levels. SHORT TERM: Winds/seas expected to remain below small craft advisory levels through the period. && .CAR WATCHES/WARNINGS/ADVISORIES... ME...None.
