Area forecast discussion, Jun 30, 2:32 PM EDT, 22 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CARIBOU ME
230 PM PM EDT MON JUN 30 2003

.SYNOPSIS...A WEAK COLD FRONT WILL CROSS THE REGION THIS EVENING.
HIGH PRESSURE WILL BRIEFLY BUILD OVER THE AREA TONIGHT. ANOTHER WEAK
COLD FRONT WILL SLIDE ACROSS MAINE TUESDAY AFTERNOON AND EVENING. HIGH
PRESSURE WILL RETURN BRIEFLY AGAIN BY EARLY WEDNESDAY. A WARM FRONT WILL
MOVE INTO THE REGION LATE WEDNESDAY. LOW PRESSURE WILL TRACK ALONG THIS
FRONTAL BOUNDARY WEDNESDAY NIGHT.

DISCUSSION...

SHORT TERM...CLUSTER OF SHOWERS AND THUNDERSTORMS MOVING ACROSS FORECAST
AREA AT THE MOMENT AHEAD OF COLD FRONT. FAST MOVEMENT OF ACTIVITY SHOULD
TAKE IT OUT OF THE AREA BY 00Z. WILL HAVE A REMAINDER OF THE AFTERNOON
PERIOD TO ACCOUNT FOR ONGOING STORMS. WEATHER WILL SETTLE DOWN QUICKLY
OVERNIGHT WITH CLEARING SKIES AS SURFACE RIDGE BUILDS OVER THE REGION. ANY
FOG SHOULD BE RELEGATED TO ISOLATED LOW AREAS...SO WILL NOT MENTION. TUE
SHOULD START OUT SUNNY...BUT AS SURFACE RIDGE SHIFTS E ANOTHER COLD FRONT
WILL ENTER NW MAINE EARLY AFTERNOON. EXPECT A SCATTERED BAND OF
SHOWERS/THUNDERSTORMS TO ACCOMPANY THIS FRONT. MODELS INDICATE THAT MOISTURE
WILL BE RATHER LIMITED SO WILL STAY WITH SCATTERED POPS WITH FRONTAL PASSAGE
FROM NW TO SE. ANOTHER SURFACE HIGH PRESSURE RIDGE WILL RETURN LATE TUESDAY
NIGHT INTO WED. ETA MOS NUMBERS LOOKED BEST THROUGH WED NIGHT.

LONG TERM...A SOMEWHAT UNSETTLED WEATHER PATTERN WILL CONTINUE FOR THIS
PERIOD OF THE FORECAST.  2 SEPARATE CUTOFF LOWS MOVING ACROSS SOUTHERN
CANADA WITH SPOKES OF VORTICITY ROTATING AROUND THEM WILL KEEP THE REGION IN
A NEUTRAL TO CYCLONIC FLOW ALOFT. THE DIFFICULTY WILL BE IN THE DAY TO DAY
TIMING OF THE VORTICITY SPOKES.  OVERALL THE GEM/GFS AND ECMWF ARE IN GOOD
AGREEMENT IN THE EVOLUTION OF THIS PATTERN.  THE GFS HOWEVER IS STRONGER
WITH ENERGY MOVING ACROSS NEW ENGLAND SATURDAY.  AS A RESULT IT HAS
STRONGER WINDS AND MORE QPF THEN THE OTHER 2 MODELS.  FOR NOW WILL LEAN
TOWARDS THE GEM/ECMWF SOLUTION WHICH RESULTS IN A COLD FRONTAL PASSAGE WITH
SHOWERS. OVERALL, THIS PATTERN WILL YIELD IN THE MOST UNSETTLED CONDITIONS
OVER NORTHERN AREAS WITH LOWER POPS TOWARDS THE COAST.  WENT A LITTLE
ABOVE MAV/MEX MAX TEMPS THROUGH THE PERIOD.  MINS LOOK REASONABLE.

MARINE...NO HEADLINES. WINDS/SEAS EXPECTED TO INCREASE WED NIGHT WHICH
WILL BE THE NEXT CHANCE FOR SMALL CRAFT CONDITIONS.

AVIATION...SHOWERS/STORMS WILL PRODUCE IFR/MVFR CONDITIONS...BUT WILL EXIT
THE AIRPORTS BY 21Z NORTH AND 23Z DOWNEAST. EXPECT VFR CONDITIONS OVERNIGHT
THROUGH 18Z TUE. FOG THREAT MINIMAL OVERNIGHT AS DEW-POINTS DROP OFF BEHIND
COLD FRONT AND BOUNDARY LAYER REMAINS WELL MIXED.
