Area Forecast Discussion National Weather Service Caribou ME 615 AM EDT Sun Aug 9 2020

SYNOPSIS. High pressure will remain across the area today. An upper level disturbance will approach later today then cross the region tonight into Monday. A cold front will approach later Tuesday, slowly cross the region Wednesday, then exit across the Gulf of Maine Thursday.

NEAR TERM /THROUGH TONIGHT/. 6 AM Update . Forecast remains on track and no significant changes were needed this hour.

Weak high pressure to the south and upper level ridging will bring a mostly sunny morning. An small upper level shortwave sliding down from the northwest will track into southern parts of western Maine this afternoon bringing a small chance for some scattered thunderstorms, mainly in the western highlands while the north remains mostly sunny. The disturbance will continue across southern Maine tonight bringing a slight chance for some spotty showers in southern spots. The north will be mostly clear and calm and some patchy fog may form across the north again late tonight. Today will be very warm with mid 80s over the interior followed by a mild night tonight with lows around 60 in most areas.

SHORT TERM /MONDAY THROUGH TUESDAY/. An upper level disturbance will cross the region Monday with isolated to scattered showers and thunderstorms. Otherwise, expect partly sunny skies north, with mostly cloudy to partly sunny skies across central and Downeast portions of the forecast area. The disturbance will exit across the Maritimes Monday night. Could still have an isolated evening shower or thunderstorms. With the exiting disturbance and loss of diurnal heating, showers/thunderstorms will then end leaving partly/mostly cloudy skies overnight. A cold front crossing Quebec province will approach the Saint Lawrence Valley later Tuesday. After any morning low clouds and fog lift and dissipate, expect partly sunny skies along with hot humid conditions. Shower/thunderstorm chances will then increase across mostly northern and central areas Tuesday afternoon in advance of the approaching cold front, with lesser chances Downeast. The cold front will begin to cross the region Tuesday night. Expect a chance of showers/thunderstorms early Tuesday night, with still a chance of showers overnight. The better shower/thunderstorm chances will remain across northern and central areas Tuesday night. Otherwise, expect partly/mostly cloudy skies Tuesday night. Temperatures will remain at above normal levels Monday/Tuesday along with humid conditions.

LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/. The cold front will slowly cross the remainder of the forecast area Wednesday, approaching the Downeast coast late. Expect a chance of showers/thunderstorms across the region Wednesday. The cold front will settle across the Gulf of Maine Wednesday night into Thursday before stalling. However, where across the Gulf of Maine the front stalls remains uncertain. Shower/thunderstorm chances will diminish Wednesday night. Could still have the slight chance of a shower/thunderstorm across Downeast areas Thursday, dependent on how close to the coast the front stalls. High pressure will build toward northern areas Thursday with partly sunny skies. Surface high pressure builds across the region Thursday night into Friday. Generally expect partly cloudy skies Thursday night through Friday. However, an upper level disturbance could support the slight chance of an afternoon shower across the north and mountains Friday. High pressure will bring mostly/partly sunny skies Saturday. Temperatures will remain at above normal levels Wednesday through Saturday.

AVIATION /10Z SUNDAY THROUGH THURSDAY/. NEAR TERM: Today: VFR. Light WSW wind.

Tonight: VFR. Light and variable wind. Slight chance of patchy fog north.

SHORT TERM: Monday . Patchy fog early. Isolated to scattered showers/thunderstorms. Otherwise, VFR.

Monday night . Generally VFR. A slight chance of an evening shower or thunderstorm. Variable conditions with any patchy fog, mostly Downeast.

Tuesday . Patchy fog early, mostly Downeast. Variable conditions with any mostly afternoon showers and thunderstorms.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
