AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAY ME
311 PM EDT THU SEP 27 2012

.SYNOPSIS...
HIGH PRESSURE BECOMES CENTERED OVER NORTHERN NEW ENGLAND TONIGHT
AND THEN MOVES INTO THE MARITIMES FRIDAY. LOW PRESSURE WILL APPROACH
FROM THE MID ATLANTIC REGION ON FRIDAY. THE LOW WILL MOVE SLOWLY
NORTHEAST TO THE NORTHERN NEW ENGLAND COASTLINE FRIDAY NIGHT THEN
REMAIN THERE THROUGH THE WEEKEND. FINALLY ON MONDAY THE LOW WILL
HEAD OFF FOR THE MARITIMES WITH HIGH PRESSURE TO FOLLOW TUESDAY
AND WEDNESDAY.

&&

.NEAR TERM /THROUGH TONIGHT/...
DUE TO HIGH PRES CENTERED OVER THE AREA TONIGHT...SKIES WILL BE
CLEAR AND WINDS CALM. RADIATIONAL COOLING WILL ALLOW FROST TO
DEVELOP IN THE MOUNTAINS AND FOOTHILLS LATER TONIGHT WHILE PLACES
FURTHER SOUTH TEMPS WILL REMAIN ABOVE THE FROST THRESHOLDS. CLOUDS
SPREADING INTO SRN AREAS LATE AT NIGHT WILL ALSO HELP KEEP TEMPS
FROM DROPPING TO MUCH OVER SOUTHERNMOST AREAS. WILL LEAN TOWARD THE
GFS MODEL FOR MUCH OF THE FCST SO WILL USE MAV TEMPS FOR OVERNIGHT
LOWS. USING THE SLOWER GFS MODEL FOR TIMING ONSET AS WELL WHICH
MAKES SENSE DUE TO THE HIGH STACKED OVER THE AREA.

&&

.SHORT TERM /FRIDAY THROUGH FRIDAY NIGHT/...
MODELS CONTINUE TO SHOW CARVING OUT OF THE L/WV TROF TO THE WEST
FRI AND FRI NIGHT. IN ADVANCE A STG S/WV GETS EJECTED NEWD THRU
NEW ENGLAND WITH AN INITIAL SHOT OF RAIN THAT WILL SPREAD ACROSS
THE AREA FRI AND THRU FRI NIGHT. QPF AMTS OF 1-2 INCHES FAIRLY
CERTAIN ACROSS MUCH OF THE AREA...THE QUESTION WILL BE LOCATION.
NAM FURTHER N...GFS MORE ACROSS THE S. WILL STAY CLOSE TO GFS
MODEL FOR TIMING AND QPF AMTS FOR FRI INTO FRI NIGHT. THIS MEANS
MAX QPF AMTS WILL BE PLACE MORE ACROSS SRN AREAS FRI AND FRI NIGHT
ASSOC WITH THE FIRST S/WV THAT ROTATES NEWD AROUND THE UPPER
CYCLONIC FLOW FROM THE DEVELOPING OHIO VALLEY UPPER LOW WHICH
GRADUALLY GETS CARVED OUT FRIDAY AND INTO THE WEEKEND. TEMPS WILL
BE COOL DUE TO A DEVELOPING ONSHORE FLOW. ALSO LATER IN THE DAY
FOG AND DRIZZLE WILL ALSO DEVELOP AS THE AIR MASS OVER MOST SRN
AND CENTRAL AREAS BECOME SATURATED.

&&

.LONG TERM /SATURDAY THROUGH THURSDAY/...
AN UNSETTLED WEATHER PATTERN LOOKS TO CONTINUE OVER THE WEEKEND
AND INTO MONDAY AS A COOL...MOIST E-NE FLOW PERSISTS. EVERY SO
OFTEN...A SHORT WAVE TROUGH WILL ROUND THE LARGER PARENT UPPER LOW
OVER THE LAKES OVER THE WEEKEND ALLOWING FOR SHOWERS FROM TIME TO
TIME. WHILE WE ARE NOT EXPECTING A COMPLETE WASHOUT THIS
WEEKEND...CLOUDS AND DRIZZLE WILL BE AROUND...ALONG WITH COOL
TEMPERATURES. THE BEST CHANCE OF AN ORGANIZED ROUND OF RAINFALL
WILL COME WHEN THE PARENT UPPER LOW LIFTS OUT OF THE LAKES AREA
AND MOVES ACROSS NEW ENGLAND. THIS APPEARS TO OCCUR LATE
SUNDAY...SUNDAY NIGHT...AND POSSIBLY INTO MONDAY.
THEREAFTER...WE/LL HAVE TO WATCH FOR THE POTENTIAL FOR SOME LIGHT
RAIN ACROSS SOUTHERN ZONES ON TUESDAY AS A SOUTHERN STREAM WAVE
MOVES TO OUR SOUTH. A BIT WARMER A DRIER FOR TUE AND WED.

&&

.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
SHORT TERM...VFR THROUGH TONIGHT. MVFR LOWERING TO IFR CONDITIONS
