AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAY ME
312 AM EDT WED SEP 3 2014

.SYNOPSIS...
A COOLER AND DRIER AIR MASS WILL MOVE INTO THE REGION TODAY IN
THE WAKE OF A COLD FRONT. HIGH PRESSURE CRESTS OVER THE AREA ON
THURSDAY THEN SHIFTS OFFSHORE ON THURSDAY NIGHT ALLOWING MORE
HUMID AIR BACK INTO THE REGION THROUGH SATURDAY. A COLD FRONT
CROSSES THE AREA SATURDAY. HIGH PRESSURE BUILDS IN EARLY NEXT
WEEK.

&&

.NEAR TERM /TODAY/...
HIGH PRESSURE BUILDS IN TODAY WITH A NORTHWEST WIND TRANSPORTING
SOME DRIER AIR INTO THE AREA. IT WILL BE LESS HUMID THAN RECENT
DAYS... THOUGH DEWPOINTS WILL NOT FALL ALL THAT FAR... STILL IN
THE UPPER 50S TO LOW 60S. THE NORTHWEST WINDS WILL PROVIDE
DOWNSLOPING CONDITIONS TO THE COASTAL PLAIN WHICH MEANS THE COAST
WILL BE THE WARMEST AREA TODAY AND THE SEABREEZE WILL STAY AWAY.

&&

.SHORT TERM /TONIGHT AND THURSDAY/...
CENTER OF HIGH PRESSURE MOVES INTO NEW YORK STATE AND WESTERN NEW
ENGLAND TONIGHT... WITH LIGHT WINDS AND A CLEAR SKY EXPECTED
ACROSS NEW HAMPSHIRE AND MAINE. THIS WILL PROVIDE GOOD RADIATIONAL
COOLING CONDITIONS... BUT DEWPOINTS WILL NOT BE ALL THAT LOW. SO
TEMPERATURES SHOULD BOTTOM OUT IN THE 50S... EXCEPT FOR THE
MOUNTAIN VALLEYS WHERE SOME 40S ARE EXPECTED. FOG IS LIKELY IN
VALLEY LOCATIONS.

HIGH PRESSURE SHIFTS OFFSHORE ON THURSDAY WITH A SOUTHERLY RETURN
FLOW EVENTUALLY STARTING BACK UP. IT WILL BE WARM... WITH MOST
AREAS REACHING THE 80S. WITH HIGH PRESSURE MOVING OFFSHORE AND
LIGHT WINDS EXPECTED... A SEABREEZE IS LIKELY AT THE COAST.

&&

.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
HIGH PRESSURE WILL CONTINUE TO MOVE OFF TO OUR EAST THURSDAY NIGHT
AND FRIDAY. THIS WILL ALLOW ANOTHER VERY WARM AND MOISTENING
AIR MASS TO ADVECT INTO OUR REGION. REMNANT ELEVATED MIXED LAYER
PLUME LOOKS TO MOVE INTO OUR AREA ON FRIDAY. THIS GENERALLY
MEANS HOTTER THAN NORMAL WEATHER. WHILE WE PROBABLY WON/T MIX ALL
THE WAY UP TO 850 MB...TEMPERATURES MAY STILL MAKE IT TO AROUND 90
ON FRIDAY IN SOME AREAS. HAVE BOOSTED GUIDANCE TEMPERATURES UP A
BIT THEN. A COLD FRONT WILL APPROACH FROM THE NW ON FRIDAY BUT
LIKELY REMAIN FAR ENOUGH AWAY TO ALLOW THE REGION TO BE DRY.
HOWEVER...A FEW THUNDERSTORMS MAY MAKE IT TO OUR EXTREME NWRN
ZONES LATE IN THE DAY.

THE COLD FRONT SLIDES INTO OUR AREA FRIDAY NIGHT AND SATURDAY AND
LOOKS TO BE ACCOMPANIED BY SHOWERS AND THUNDERSTORMS. DEPENDING ON
THE EXACT TIMING OF THE FRONT...A FEW STORMS MAY BE SEVERE GIVEN
HOT/HUMID AIR MASS AND RELATIVELY STEEP MID LEVEL LAPSE RATES
THAT SHOULD BE IN PLACE. THIS FRONT MAY DEVELOP ANAFRONTAL
CHARACTERISTICS LATE SATURDAY INTO EARLY SUNDAY AND WOULD MEAN
SHOWER ACTIVITY COULD LINGER INTO EARLY SUNDAY.

HIGH PRESSURE LOOKS TO BUILD INTO THE REGION SUNDAY THROUGH EARLY
NEXT WEEK WITH FAIR WEATHER EXPECTED.

&&

.AVIATION /07Z WEDNESDAY THROUGH SUNDAY/...
SHORT TERM...AFTER SOME PATCHY MORNING FOG... EXPECT VFR
CONDITIONS TODAY WITH A NORTHWEST WIND GUSTING TO 15 TO 20 KT.
VALLEY FOG WILL LIKELY FORM TONIGHT IN THE CONNECTICUT RIVER
VALLEY AND POSSIBLY AT CONCORD AS WELL.

LONG TERM...THURSDAY NIGHT THROUGH SUNDAY...MAINLY VFR EXPECTED. 
HOWEVER...SHOWERS AND STORMS SATURDAY WILL MAKE FOR LOCALLY LOWER
CONDITIONS. SOME COASTAL FOG AND STRATUS MAY MAKE FOR LOWER
CONDITIONS ON THE COAST FRIDAY INTO SATURDAY WITH ANY ONSHORE
COMPONENT THAT DEVELOPS IN THE MOISTENING AIR MASS.

&&

.MARINE...
SHORT TERM...NORTHWEST FLOW TODAY SHOULD STAY JUST BELOW ADVISORY
LEVELS. THE OFFSHORE WINDS SHOULD PREVENT WAVE HEIGHTS FROM RISING
ABOVE 5 FT. WINDS SUBSIDE AS HIGH PRESSURE MOVES OVERHEAD BY
THURSDAY.

LONG TERM...A SCA MAY BE NEEDED FRIDAY NIGHT AND SATURDAY AHEAD
OF THE APPROACHING COLD FRONT AS WINDS INCREASE FROM SOUTH.

&&
