AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CARIBOU ME
140 PM EDT WED JUL 30 2003

.SYNOPSIS...
A WEAK UPPER LEVEL DISTURBANCE WILL MOVE EAST OF THE REGION EARLY
TONIGHT. A WEAK AREA OF HIGH PRESSURE WILL THEN REMAIN IN CONTROL OF
THE WEATHER ACROSS THE REGION INTO FRIDAY.

DISCUSSION...
SHORT TERM (TONIGHT-THU NIGHT)
THE MAIN CONCERN THROUGH THIS EVENING WILL BE DEALING WITH
CONVECTION IN ASSOCIATION WITH APPROACHING VORT MAX SHOWING UP VERY
NICELY IN H2O IMAGERY. THIS FEATURE WILL SWING THROUGH EXTREME
NORTHERN MAINE EARLY THIS EVENING. WILL CARRY SCATTERED RW/TRW REST
OF THIS AFTERNOON AND INTO EARLY EVENING NORTHERN ZONES. ACTIVITY
SHOULD DIMINISH QUICKLY THIS EVENING AS THE S/WV VORT MAX MOVES OFF
TO THE EAST. WILL ALSO MENTION PATCHY FOG DEVELOPING OVERNIGHT WITH
LIGHT WINDS. FOR THURSDAY AND THURSDAY NIGHT INCREASING RIDGING
ALOFT AND HIGH PRESSURE AT THE SURFACE WILL RESULT IN DRY WEATHER.
BASICALLY USED THE ETAMATCHMOS WITH SOME MINOR ADJUSTMENTS THROUGH
THE PERIOD.

LONG TERM (FRI-WED)
LEANED W/A BLEND OF THE GEM/GFS FROM FRI INTO SUN & THEN I TOOK A
CONSENSUS OF THE LONG RANGE PROGS FROM MON-WED. AN AREA OF LOW PRES
WILL MOVE ACROSS DOWNEAST AREAS PER GFS/GEM FRI INTO EARLY SAT. FAR
NORTHERN MAINE LOOKS TO BE ON THE NORTHERN FRINGE OF THE PRECIP
SHIELD. BEST CHC FOR WET WX IS FROM GNR-LRG ONTO BGR & BHB. I KEPT
SLGT CHC IN THE GRIDS FOR NORTHERN SITES W/THINKING THAT SYSM COULD
EDGE FURTHER N. SYSM PULLS INTO NEW BRUNSWICK LATE SAT W/FRONTAL
BOUNDARY HANGING UP ACROSS DOWNEAST AND COASTAL AREAS. NORTHERN AND
CENTRAL AREAS SHOULD DRY OUT LATER SAT INTO SUN W/BGR-BHB REMAINING
UNSETTLED W/THREAT FOR SHRA BASED ON PROXIMITY OF THE FRONT. FOR MON
INTO WED... I KEPT NORTHERN ZONES DRY THRU THE EARLY PART OF THE
BANKING ON HIGH PRES NOSING DOWN INTO NORTHERN & CENTRAL MAINE. THEN
AS UPPER LEVEL SYSM MIGRATES EAST W/SFC LOW PRES MOVING INTO THE
CWFA...I WENT AHEAD & STAYED W/PRVS FCST OF SHRA LATE MON INTO WED.
I THREW MENTION OF TSRA TUE AFTN INTO TUE NIGHT W/WARM SECTOR &
FRONTAL SYSM APCHG. MASSAGED PRVS TEMPS DUE TO LATEST MRF/MEX. I
BOOSTED MINS MON NIGHT & TUE NIGHT W/CWFA BEING UNDER SSW FLOW &
MOIST AIRMASS.

MARINE...NO HEADLINES ANTICIPATED NEXT SEVERAL DAYS.

AVIATION...EXPECT SCATTERED SHOWERS/THUNDERSTORMS TO AFFECT CAR...
PQI...HUL AIRPORTS THROUGH EARLY EVENING. OTHERWISE GENERALLY VFR
CONDITIONS CAN BE EXPECTED THROUGH EARLY THURSDAY. THE EXCEPTION
WILL BE THE POSSIBILITY OF SOME PATCHY FOG OVERNIGHT WHICH COULD
REDUCE VSBYS TO MVFR AT TIMES.

.CAR...NONE.

SHORT TERM...DUDA
LONG TERM...HEWITT
