607 FXUS61 KCAR 241842 AFDCAR Area Forecast Discussion National Weather Service Caribou ME 242 PM EDT SUN JUL 24 2016 .SYNOPSIS...
-- Changed Discussion --
High pressure will crest over the area tonight then move east on Monday. A warm front will lift across the area Monday night followed by a cold front on Tuesday.
-- End Changed Discussion --
&& .NEAR TERM /THROUGH MONDAY/...
-- Changed Discussion --
Cumulus clouds across the area will dissipate this evening. Tonight will then be clear, tranquil and comfortable as high pressure crests over the area. An approaching trough of low pressure will bring increasing clouds on Monday. Some showers may stray into western areas late in the day as a warm front approaches. Atmospheric sounding forecasts show generally stable air at the low levels on Monday so the chances for thunderstorms will likely be low. The best chance for a thunderstorm late Monday will be in far western areas where warm air west of the mountains is lifting over the terrain and the more stable air mass over our region. Will have scattered thunderstorms in far western areas late in the day with isolated thunderstorms elsewhere along with the scattered to numerous showers moving eastward.

&& .SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/...
-- Changed Discussion --
Fairly unsettled pattern through midweek with temperatures a little above average. Showers likely Monday night most areas with perhaps a few embedded storms. Moist airmass could lead to some locally heavy rain, but it won`t rain everywhere. Models still having some timing issues with the system Monday night plus or minus about six hours. For Tuesday, moist airmass remains and with a bit of cooling aloft and an upper level shortwave trough passing through, could see some storms with small hail. However, shorwave timing is a bit faster than ideal, as trough axis is to the New Brunswick border by early afternoon. So don`t think our storm coverage and strength Tuesday will be as much as it could be if the shortwave was moving a bit slower. Slight drier airmass moves in Tuesday night and Wednesday, but with fairly unstable westerly flow Wednesday, still not convinced Wednesday will be dry. Put in a chance of storms for the north, closer to the upper level low to our NW in Quebec.

&& .LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
-- Changed Discussion --
Lower than average confidence in the forecast Wednesday night and beyond. Not looking for anything exceptionally hot or cool, or anything exceptionally wet or dry. But precipitation chances day to day are quite uncertain from Wednesday night through the weekend. Generally, looking for a slow moving weak cold front to work its way southeast through the area Wednesday night through Friday. But the front`s progress is very much in question. It could clear the coast Thursday with drying, or hang on until Friday night with storm chances persisting. Tentatively expect Saturday to early Sunday to be dry with near average temperatures.
