TODAY, SURFACE HIGH PRESSURE STAYS OVER MAINE, WHILE A
STATIONARY COASTAL LOW PRESSURE DOWN BY VIRGINIA SLOWLY CREEPS
NORTHEAST TOWARDS THE GULF OF MAINE. DRY CONDITIONS WITH LIGHT
SOUTHERLY FLOW. GENERALLY CLEAR SKIES IN THE NORTH, WITH CLOUDS
MOVING IN FROM THE SOUTH ALONG THE COAST AHEAD OF APPROACHING
LOW PRESSURE SYSTEM. GENERALLY HIGH TEMPERATURES IN THE 70S
THROUGHOUT NORTHERN AND DOWNEAST MAINE. MOST MODEL GUIDANCE HAS
THE LOW PRESSURE TRACKING FAR ENOUGH SOUTH OF THE GULF OF MAINE
THAT RAIN WILL STAY OVER THE WATERS. SLIGHT CHANCE FOR SOME
LIGHT RAIN ALONG THE IMMEDIATE COASTLINE DURING THE
EVENING/NIGHTTIME. MOST OF THE ELEVATED SMOKE MOVES OUT OF MAINE
TODAY, BUT THERE COULD BE ANOTHER CHANCE FOR ELEVATED SMOKE
THURSDAY.
TONIGHT, SURFACE HIGH PRESSURE OVER THE REGION, AS A COLD FRONT
FROM AN APPROACHING LOW PRESSURE SYSTEM TO THE NORTHWEST MOVES
CLOSER TO MAINE. PARTIALLY CLOUDY SKIES ALONG THE DOWNEAST COAST
AND CROWN OF MAINE, BUT RELATIVELY CLEAR SKIES IN CENTRAL
MAINE. OVERNIGHT LOW TEMPERATURES IN THE MID-40S. YET ANOTHER
NIGHT WITH A POTENTIAL FOR SOME RIVER VALLEY FOG. VERY SLIGHT
CHANCE FOR SOME LIGHT RAIN SHOWERS TO MOVE INTO THE CROWN OF
MAINE AHEAD OF THE APPROACHING COLD FRONT LATE TONIGHT/EARLY
TOMORROW.
THURSDAY, COLD FRONT CROSSES THE STATE. VERY MINIMAL INSTABILITY
WITH THIS FRONT, SO STILL NOT EXPECTING ANY RAIN SHOWERS OUTSIDE
OF A FEW STRAY ONES IN THE FAR NORTH IN THE MORNING. NORTHERN
MAINE WILL HAVE DAYTIME HIGHS A BIT COOLER SINCE THE FRONT
PASSES EARLY IN THE DAY, KEEPING AREAS AROUND THE MID-60S.
DOWNEAST WILL BE IN THE WARM SECTOR FOR MOST OF THE DAY, SO
DAYTIME HIGHS EXPECTED TO BE IN THE 70S. MOSTLY CLEAR SKIES.
SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY/
