Area Forecast Discussion National Weather Service Caribou ME 355 AM EDT Thu Aug 13 2020

SYNOPSIS. A secondary cold front will approach late this afternoon and cross the region this evening. High pressure will build across the region Friday through this weekend. A front will approach from the west Monday.

NEAR TERM /THROUGH TONIGHT/. Satellite imagery this morning shows nearly completely clear skies across the forecast area. A weak shortwave trough and right entrance region of a 250mb jet streak will work into northern Maine this afternoon. While the 0z sounding from CAR shows a strong inversion around 750mb and substantial dry air aloft, the aforementioned forcing should be enough for at least a couple isolated showers from near and just north of Baxter State Park into southern/central Aroostook County during peak diurnal heating. Thunder is unlikely given the dry air aloft, inversion around 10,000 feet AGL, and high freezing levels. Lower dew points and mostly sunny skies will allow temperatures to warm efficiently into the mid/upper 80s, approaching yesterday’s highs. A secondary cold front will move in from the north tonight, reinforcing dry air and cooling temperatures aloft more than the first front that passed through yesterday. Lingering moisture around 850mb will lead to just enough cloud cover to make the low temperature forecast tricky tonight. A somewhat clearer and cooler solution was preferred, with the typical cool spots of northern Maine forecast to drop into the 40s to low 50s.

SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/. Sfc hipres building south out of nrn Quebec wl bring mainly tranquil wx to the CWA thru the end of the week and into the early part of the weekend. H5 trof wl be dropping thru the state on Friday, possibly resulting in chance for showers acrs the north drg the aftn hrs. With fairly light pressure gradient may see a sea breeze dvlp keeping the coast and outer islands in the 70s for max temps with interior Downeast zones into the 80s. Cooler H8 temps wl be filtering in acrs the north and with clds and showers expected with upr trof nrn zones likely to rmn in the u70s for highs.

Showers wl diminish Fri evng with loss of diurnal htg but clds likely to linger in nerly flow. Mins wl dip into the u50s acrs the south and possibly into the u40s over the far northwest.

By Sat morning med range guidance begins to diverge on upr air pattern with 00z EC/UK closing H5 low off over NB while GFS/CMC indicating troffing undercutting H5 high set up ovr ern Quebec. Hv opted to go with continuity with more progressive soln of GFS and Canadian and continue with nr normal temps on Sat and skies clouding up fm the east on Sun morning in n-nerly flow.

LONG TERM /SUNDAY THROUGH WEDNESDAY/. Extndd period begins with a rex block over ern half of Maine and NB per EC while the GFS and CMC are more progressive with trof ejecting east twd the Maritimes Sun morning with H5 ridge over the state. As expected this delays pcpn timing for early next week with GFS/CMC bring showers into the ern half of CWA Mon morning and mvg them out of the region late Mon night. Due to uncertainly on model solns, hv contd with chc pops as H5 trof wl set up over the ern half of the U.S. due to 596 high taking shape over the west early in the week. Still expecting abv normal temps thru end of the long term.

AVIATION /08Z THURSDAY THROUGH MONDAY/. NEAR TERM: VFR with NW wind gusts up to around 15 kts this afternoon.

SHORT TERM: Fri . VFR with possible VFR over nrn terminals in localized showers. NNE 5-10kts.

Fri night-Sat . VFR becoming MVFR Sat morning. ENE 5-10kts.

Sat night-Sun night . VFR, possible MVFR restrictions mvg in late Sun night in low cigs and showers. Light E Sat night becoming SE 5kts Sun afternoon.

Mon . MVFR, localized IFR in showers. S 5-10kts.

MARINE. NEAR TERM: Winds and seas will remain below SCA levels.

SHORT TERM: Winds and seas remain blo SCA through Sat morning. May see marginal wind gusts late Fri night to between 20-25kts before diminishing Sat afternoon. Seas and winds may increase to near SCA levels on Monday.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
