SYNOPSIS. Low pressure will draw a warm front across the region tonight, with a cold front then crossing Friday. The low will exit across the Maritimes Saturday into Sunday. High pressure will build toward the region Monday into Tuesday.

NEAR TERM /THROUGH FRIDAY/. Low pressure will lift northeast along the Saint Lawrence River Valley tonight through Friday. The low will draw a warm front north across the region tonight, then draw a cold front across the region Saturday. An area of showers will cross the region early tonight. Isentropic lift to the north of the warm front will then support an area of light rain which will lift north across the region overnight, with the better rain chances across central and northern areas. Patchy fog will also develop overnight and persist early Friday. Showers will occur in advance of the cold Friday morning into the afternoon, with decreasing shower chances later in the afternoon in the wake of the cold front. Could also have just enough instability to support isolated thunderstorms in advance of the cold front. Low temperatures tonight will range from the upper 40s to around 50 north, to the lower to mid 50s Downeast. High temperatures in advance of the cold front Friday will range from the upper 50s to around 60 north, to the mid 60s Downeast.

SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/. The cold front stretching across the state is expected to continue to move SE through Friday night. Recent QPF models show some lingering showers across the north and east which should dissipate by early morning Saturday. 850-200mb RH models show plenty of cloud cover for the night, thus keeping temps slightly above normal. However, advancing cold air behind the front will bring temps into the upper 30s in the North Woods with low to mid 40s across the rest of the region. By Saturday, the upper level low will continue to spin over James Bay, pulling in shortwaves across the area. These shortwaves are expected to bring sporadic chances of showers to the region throughout the day. 925-850 mb temps show cold air advection will continue to push into the state from the NE, making temps fall slightly below normal.

By Saturday night, the upper level low starts to move eastward, pushing the surface low out of the area. Weak high pressure should push out clouds in the south, while the north could see some rain showers. Cold air advection will push temps into the 30s for the area with possible 20s in the North Woods. By Sunday, some clouds should return in the south with the advancement of the upper level low. In the early morning, the upper level jet is expected to stretch across the waters influencing a low level jet. This should increase NW winds over the waters. As the day continues, this jet should move northward, causing breezy W winds across the waters and region with gusts up to 25 mph.

LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/. The exiting upper level low and the approaching high pressure will influence the region for the early week. Sunday night should see below normal temps in the low to mid 30s. For Monday and Tuesday, the clouds should clear out making for a mostly clear skies and near normal temps. By Wednesday, a low pressure system over the mid-Atlantic states is expected to move towards the state. Canadian models seem to be the only model showing the low taking a turn northwards, causing quite a bit of rain. However, the GFS and Euro still show the low tracking eastwards, though recent model runs for the Euro show some moisture making its way into the area. Nevertheless, decided to include only slight chance of rain for the area, as confidence is fairly low at this time.

AVIATION /21Z THURSDAY THROUGH TUESDAY/. NEAR TERM: Conditions will lower to IFR/LIFR levels tonight. IFR/LIFR conditions persist Friday morning, with MVFR/IFR conditions Friday afternoon. Rain and showers tonight into Friday, with decreasing shower chances later Friday afternoon in the wake of a cold front. An isolated thunderstorm also possible in advance of the cold front Friday morning through early afternoon. South/southeast winds around 10 to 15 knots tonight. South/southwest winds 10 to 20 knots, becoming west/northwest, Friday.

SHORT TERM: Fri night-Sat night . Mainly VFR, possible MVFR in rain showers. Light variable winds becoming NNW on Sat.

Sunday . VFR. Light WNW winds increasing becoming W in the afternoon 10-15 kts with gusts up to 20 kts.

Sun night-Tue . VFR. NNW winds 5-10 kts, decreasing to light winds by Mon night.

MARINE. NEAR TERM: Winds/seas will gradually increase tonight. A Small Craft Advisory has been issued for much of the waters, with the exception of the intracoastal waters, from Friday morning through Friday evening. Visibilities reduced in rain and showers along with patchy fog tonight into Friday.

SHORT TERM: Seas expected to drop below SCA conditions by Friday night. Winds and seas should remain below SCA until Saturday night after midnight when gusts are expected to increase to 25 kts. By Monday morning, winds should decrease to below SCA for the rest of the period.

CAR WATCHES/WARNINGS/ADVISORIES. ME . None. MARINE . Small Craft Advisory from 6 AM to 8 PM EDT Friday for ANZ050- 051.
