AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAY ME
233 PM EDT SAT SEP 27 2014

.SYNOPSIS...
HIGH PRESSURE WILL HOLD OVER THE REGION TONIGHT THROUGH SUNDAY. A
COLD FRONT WILL DROP SOUTH THROUGH THE REGION SUNDAY NIGHT AND
WILL PUSH SOUTH OF THE REGION ON MONDAY. HIGH PRESSURE WILL BUILD
IN FROM THE NORTHWEST TUESDAY THROUGH WEDNESDAY AND WILL HOLD OVER
THE REGION THROUGH FRIDAY.

&&

.NEAR TERM /THROUGH TONIGHT/...
CLEAR AND COOL TONIGHT AS CLEAR SKIES AND LIGHT WINDS ALLOW FOR
GOOD RADIATIONAL COOLING. LOW TEMPS IN COLDER MOUNTAIN VALLEYS
WILL DIP INTO THE MID TO UPPER 40S. ELSEWHERE LOWS WILL BE IN THE
LOWER TO MID 50S.


&&

.SHORT TERM /SUNDAY/...
CLEAR AND QUIET WEATHER CONTINUES ON SUNDAY WITH HIGHS SIMILAR TO
TODAY. EXPECT MOST OF THE AREA TO TOP OUT WITH A FEW DEGREES OF
80.

COLD FRONT WILL DROP SOUTH THROUGH THE REGION SUNDAY NIGHT. ASIDE
FROM INCREASING CLOUDS IN NORTHERN ZONES AFTER MIDNIGHT SHOULD BE
A DRY NIGHT AS SHOWER ACTIVITY REMAINS NORTH OF THE BORDER. LOWS
WILL ONCE AGAIN BE IN THE MID TO UPPER 40S NORTH AND LOWER TO MID
50S SOUTH.


&&

.LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/...
THE MODELS ARE IN GENERAL AGREEMENT ON THE LONG WAVE PATTERN
THROUGH LATE NEXT WEEK. WE BEGIN THE PERIOD WITH A WEAK UPPER
TROUGH AND AN WEST-EAST ORIENTED COLD FRONT DROPPING SLOWLY
SOUTHWARD ACROSS THE AREA LATE MONDAY THROUGH TUESDAY. BY
MIDWEEK...THE CANADIAN-NH AND GFS REPLACE THE TROUGH WITH
RIDGING...WHILE THE ECMWF IS THE OUTLIER WITH LOW PRESSURE
SURFACE AND ALOFT SITUATED JUST TO OUR SOUTH. I`M BEEN A BIT MORE
OPTIMISTIC THEN THE ECMWF FOR THIS FORECAST...ESPECIALLY FOR
WEDNESDAY AND THURSDAY. HOWEVER...THE GFS AND CANADIAN STILL PAINT
A PICTURE OF PERSISTENT ONSHORE FLOW AS THE SURFACE HIGH SLIDES BY
TO OUR NORTH. SO...I`M INCLINED TO BRINGS CLOUDS AND CHANCE/SLIGHT
CHANCE POPS INTO SOUTHERN SECTIONS BY FRIDAY. BY NEXT WEEKEND...THE
MODELS COME BACK INTO BETTER AGREEMENT WITH A BROAD UPPER TROUGH
AND ASSOCIATED SURFACE COLD FRONT BRINGING AN INCREASING CHANCE OF
RAIN.

&&
