SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY/
AFTER A VERY COLD NIGHT THURSDAY NIGHT, TEMPERATURES START TO
REBOUND FRIDAY THROUGH SATURDAY. IN FACT, BY SATURDAY WE WILL SEE
DAYTIME HIGHS RUNNING AROUND 5 TO 10 DEGREES ABOVE NORMAL.
AS FAR AS THE SYNOPTIC PATTERN GOES, A NORTHEAST TO SOUTHWEST
ORIENTED SURFACE HIGH WILL BE ACROSS THE REGION THURSDAY NIGHT.
MAINLY CLEAR SKIES AND LIGHT WINDS WILL SET THE STAGE FOR A GOOD
RADIATIONAL COOLING NIGHT, WITH LOWS FALLING TO 10 BELOW TO 20 BELOW
ACROSS NORTHERN AREAS AND 5 BELOW TO 10 BELOW ACROSS MUCH OF CENTRAL
AND DOWNEAST MAINE.
A WARM FRONT WILL APPROACH THE REGION ON FRIDAY AND THEN LIFT ACROSS
THE REGION LATER FRIDAY AND FRIDAY NIGHT. HIGH TEMPERATURES ON
FRIDAY WILL MODERATE INTO THE MID TO UPPER TEENS ACROSS THE
NORTH AND LOWER 20S ACROSS CENTRAL AND DOWNEAST AREAS. A FEW
FLURRIES OR ISOLATED SNOW SHOWERS ARE POSSIBLE WITH THE PASSAGE

MID TO UPPER 30S CENTRAL AND DOWNEAST.
LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/
ABOVE NORMAL TEMPERATURES ARE EXPECTED TO CONTINUE RIGHT THROUGH THE
MIDDLE OF NEXT WEEK AS THE UPPER FLOW BECOMES MORE SOUTHWESTERLY
WITH TIME. THIS WILL RESULT IN THE COLDEST AIR REMAINING NORTH OF
THE BORDER. IN FACT, THE LATEST CPC 6 TO 10 DAY OUTLOOK FAVORS
ABOVE NORMAL TEMPERATURES THROUGH MUCH OF NEXT WEEK. HOWEVER, IT
ALSO FAVORING THE PROBABILITY OF PRECIPITATION SOMEWHAT ABOVE
NORMAL AS WELL. SUNDAY NIGHT THROUGH MONDAY LOOK DRY. DID LOWER
NBM POPS ON MONDAY AS THEY LOOKED A BIT TO HIGH, THUS KEPT IT
DRY THROUGH MONDAY. PRECIPITATION CHANCES BEGIN TO INCREASE
LATER MONDAY NIGHT THROUGH TUESDAY AS THE NEXT SYSTEM MOVES
TOWARD THE REGION. PRECIPITATION TYPE STILL UP IN THE AIR AS
LONGER RANGE MODELS STILL UNCERTAIN WITH REGARD TO THE LOW
TRACK. FOR NOW, WILL JUST GO CHANCE POPS LATER MONDAY NIGHT INTO

REGION MID TO LATE NEXT WEEK.
