HIGH PRESSURE WILL MOVE EAST OF THE AREA TODAY. A WEAK COLD FRONT
APPROACHES LATE TONIGHT AND CROSSES THE REGION ON SATURDAY.

.NEAR TERM /THROUGH TONIGHT/...
UPDATE...
ANOTHER VERY COLD MORNING ACROSS THE CWA WITH SEVERAL SUB ZERO
READINGS. BIG BLACK RIVER CURRENTLY REPORTING -23F WITH WIDESPREAD
-5 TO -10 ACROSS MOST OF THE REST OF THE COUNTY. TEMPERATURES WILL
RECOVER QUITE RAPIDLY THIS MORNING AS SOUTHWEST WINDS ALLOW THE
INVERSION TO QUICKLY BREAK. HIGH CLOUDS ALREADY SHOWING UP OUTSIDE
THE WINDOW HERE BUT STILL PLENTY OF SUNSHINE EXPECTED TODAY. MINOR
TWEAKS TO HOURLIES OTHERWISE CURRENT FORECAST STILL LOOKING GOOD.

HIGH PRESSURE WILL MOVE EAST OF THE GULF OF MAINE TODAY. A SOUTHWEST
RETURN FLOW AROUND THE HIGH WILL ALLOW AFTERNOON HIGH TEMPERATURES
TO REACH TO NEAR NORMAL LEVELS...SOMETHING THAT HASN`T HAPPENED IN
QUITE SOME TIME AROUND HERE. HIGHS TODAY ARE EXPECTED TO RANGE FROM
THE LOW 30S NORTH AND MID 30S ACROSS CENTRAL AND DOWNEAST. OUTSIDE
OF SOME HIGH CLOUDS WE WILL ONCE AGAIN SEE PLENTY OF SUNSHINE
TODAY.

A COLD FRONT WILL APPROACH FROM THE NORTHWEST TONIGHT. INCREASING
CLOUDS IN ADVANCE OF THE FRONT AND LIGHT SOUTHWEST WINDS WILL PUT
AN END TO THE WIDESPREAD SUBZERO LOW TEMPERATURES OF THE PAST
SEVERAL DAYS. IN FACT...AS OF THIS MORNING CARIBOU HAS SEEN
ELEVEN STRAIGHT DAYS OF SUB ZERO LOW TEMPERATURES.

LOW TEMPERATURES TONIGHT WILL RANGE FROM THE MID TO UPPER TEENS
ACROSS NORTHERN AND CENTRAL AREAS AND THE UPPER TEENS TO LOWER 20S
DOWNEAST. THERE WILL BE THE CHANCE FOR A FEW SNOW SHOWERS TOWARD
MORNING ACROSS NORTHERN AREAS...ESPECIALLY THE SAINT JOHN VALLEY
AS THE FRONT APPROACHES. ANY SNOW ACCUMULATIONS WILL BE LESS THAN
AN INCH.
