346 AM EDT WED AUG 26 2015
.SYNOPSIS...
A SLOW MOVING COLD FRONT WILL CROSS THE AREA TODAY AND MOVE EAST
OF THE REGION TONIGHT. AN UPPER LEVEL TROUGH WILL MOVE OVER THE
AREA THURSDAY. A SURFACE HIGH WILL BUILD SOUTH OF THE REGION
FRIDAY. A WEAK COLD FRONT WILL MOVE INTO NORTHERN MAINE OVER THE
WEEKEND.
&&
.NEAR TERM /THROUGH TONIGHT/...
A COLD FRONT WILL SLOWLY APPROACH THE REGION FROM THE WEST TODAY.
EXPECT SHOWERS AND ISOLATED TSTMS ACROSS THE REGION IN ADVANCE OF
THE APPROACHING FRONT TODAY. DEEP LAYERED SOUTHERLY FLOW AND
ABUNDANT LOW LEVEL MOISTURE IN ADVANCE OF THE FRONT WILL RESULT IN
LOCALLY HEAVY RAINFALL AT TIMES, ESPECIALLY IN ANY ISOLATED TSTMS.
PRECIPITABLE WATER VALUES IN EXCESS OF 1.5 INCHES WILL ALSO
SUPPORT LOCALLY HEAVY RAINFALL AMOUNTS. HIGHS TODAY WILL RANGE
FROM THE LOW TO MID 70S.
THE COLD FRONT WILL GRADUALLY CROSS THE REGION OVERNIGHT. EXPECT
SHOWERS AND ISOLATED TSTMS TO GRADUALLY DIMINISH FROM WEST TO EAST
OVERNIGHT WITH THE PASSAGE OF THE FRONT. LOW TEMPERATURES
OVERNIGHT WILL RANGE FROM THE MID 50S NORTH TO AROUND 60 DOWN
EAST.
&&
.SHORT TERM /THURSDAY THROUGH FRIDAY/...
AN UPPER TROUGH WILL MOVE EAST ACROSS THE AREA THURSDAY. SCATTERED
SHOWERS WILL ACCOMPANY THE TROUGH PASSAGE ACROSS THE NORTHERN ZONES
WITH NOTHING MORE THAN AN ISOLATED SHOWER OR A FEW SPRINKLES DOWN
EAST. AS THE AIR MASS COOLS ALOFT THERE MAYBE JUST ENOUGH
INSTABILITY FOR AN ISOLATED THUNDERSTORM MID-LATE AFTERNOON IN
THE NORTH.
AS THE UPPER TROUGH MOVES EAST OF THE AREA THU NIGHT AND A SFC HIGH
BUILDS TO THE SOUTHWEST OF THE AREA THE SKY WILL BECOME CLEAR TO
PARTLY CLOUDY. IT WILL BE COOLER AND LESS HUMID WITH TEMPS LIKELY
TO DROP INTO THE 40S IN THE NW VALLEYS WITH LOW TO MID 50S FOR THE
REMAINDER OF THE AREA.
HIGH PRESSURE SLIDES SOUTH OF THE REGION FRI AS A WEAK COLD FRONT
APPROACHES FROM THE NORTHWEST. EXPECT A SUNNY DAY DOWN EAST WITH
SUNSHINE TO MIX WITH SOME AFTERNOON CLOUDS IN THE NORTH. HUMIDITY
LEVELS WILL BE ON THE LOW SIDE WITH TEMPS JUST A FEW DEGREES ABOVE
NORMAL FOR LATE AUGUST.
&&
.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
THERE REMAINS UNCERTAINTY THIS WEEKEND. A FRONTAL BOUNDARY IS
EXPECTED TO DROP INTO NORTHERN MAINE AND BECOME QUASI-STATIONARY.
THE ECMWF CONTINUES TO KEEP THE AREA MAINLY DRY WITH JUST THE
CHANCE OF A SHOWER OR TWO ACROSS MAINLY NORTHERN MAINE. THE GFS
PULLS MORE SUB-TROPICAL MOISTURE NORTH WITH A SFC WAVE IN THE
MIDWEST, AND HAS A MUCH WETTER SOLUTION FOR SUNDAY. IT LOOKS LIKE
AN UPPER RIDGE WITH HIGH HEIGHTS BECOME DOMINATE AGAIN EARLY NEXT
WEEK WITH MAINLY DRY WEATHER AND ABOVE NORMAL TEMPS AS WE CLOSE
OUT AUGUST AND START SEPTEMBER.
THE LONG RANGE OUTLOOKS FOR WEEK TWO FROM THE CPC...CFSV2...AND
HEMISPHERIC MODELS WOULD POINT TOWARD ABOVE NORMAL TEMPERATURE FOR
THE FIRST WEEK OF SEPTEMBER.
