AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CARIBOU ME
856 AM EDT FRI JUL 6 2007

.SYNOPSIS...
LOW PRESSURE WILL MOVE ACROSS MAINE TO THE MARITIMES TODAY...DRAWING
A COLD FRONT ACROSS THE REGION WITH SHOWERS AND THUNDERSTORMS.
THE COLD FRONT WILL MOVE TO THE EAST TONIGHT WITH DIMINISHING
SHOWER CHANCES. A DISTURBANCE WILL CROSS THE REGION SATURDAY
POSSIBLY BRINGING A CHANCE OF SHOWERS DURING THE AFTERNOON MOSTLY
TO DOWNEAST AREAS. A WARM FRONT WILL BECOME NEARLY STATIONARY
ACROSS THE REGION SUNDAY BRINGING ANOTHER CHANCE OF SHOWERS.
&&

.NEAR TERM /THROUGH SATURDAY/...
DENSE FOG IS LIFTING ACROSS DOWNEAST SO WILL CANCELLED THE DENSE
FOG ADVISORY FOR THE REMAINDER OF THIS MORNING. SKIES CLEARING TO
THE WEST AND EXPECT STRATUS DECK WILL LIFT ACROSS THE REGION LATE
THIS MORNING PROVIDING PARTLY CLOUDY SKIES ACROSS THE REGION BY
NOONTIME. RADAR INDICATES THAT ISOLATED SHOWERS ARE CONFINED TO
THE COASTAL SECTIONS SO WILL ALSO REDUCE POPS ACROSS THE CWA THIS
MORNING BUT LEAVE NUMEROUS POPS FOR THIS AFTERNOON.

LOW PRESSURE WILL LIFT ACROSS MAINE TODAY DRAWING A COLD FRONT
ACROSS THE REGION. AT THE SAME TIME...AN UPPER DISTURBANCE WILL
TRACK ALONG THE COAST WHILE AN UPPER TROF CROSSES THE FORECAST
AREA. SHOWERS/THUNDERSTORMS WILL OCCUR ACROSS THE REGION TODAY.
TEMPERATURES ALOFT BEGIN TO COOL TODAY WITH THE UPPER TROF WHICH
WILL HELP STEEPEN LAPSE RATES. AT THE MOMENT...ABUNDANT CLOUD
COVER IS EXPECTED ACROSS THE REGION TODAY WHICH WOULD LIMIT
DIURNAL HEATING. HOWEVER...IF MORE EXTENSIVE SUN AND DIURNAL
HEATING DOES OCCUR DESTABILIZATION WILL BE ENHANCED WITH MORE
EXTENSIVE AND STRONGER THUNDERSTORMS. SOME THUNDERSTORMS WHICH
FORM TODAY COULD PRODUCE SMALL HAIL AND GUSTY WINDS. FOG WILL
OCCUR ACROSS THE REGION THIS MORNING WHICH COULD BE LOCALLY DENSE
ACROSS NORTHERN AREAS. MORE EXTENSIVE AND PERSISTENT DENSE FOG
WILL OCCUR ACROSS CENTRAL/DOWNEAST AREAS THIS MORNING WHERE A DENSE
FOG ADVISORY IS IN EFFECT THROUGH NOON. HIGH TEMPERATURES TODAY
WILL BE DEPENDENT ON THE AMOUNT OF SUN...THOUGH GENERALLY EXPECT
READINGS TO RANGE FROM AROUND 70 NORTH TO THE MID 70 INTERIOR
DOWNEAST WITH AROUND 70 NEAR THE DOWNEAST COAST.

THE LOW WILL CONTINUE MOVING NORTHEAST THROUGH THE MARITIMES
TONIGHT...DRAWING THE COLD FRONT ACROSS THE GULF OF MAINE. THE
UPPER TROF WILL ALSO MOVE EAST. THUS...EXPECT SHOWERS/THUNDERSTORMS
ACROSS THE REGION DURING THE EVENING TO BECOME LESS EXTENSIVE
OVERNIGHT. LOW TEMPERATURES TONIGHT WILL RANGE FROM THE LOWER TO MID
50S NORTH...TO THE MID 50S DOWNEAST.
&&

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/...
THE COLD FRONT WILL CONTINUE TO MOVE EAST ACROSS THE MARITIMES
EARLY SATURDAY. EXPECT A PARTLY SUNNY DAY SATURDAY. HOWEVER A
WEAK SHORT WAVE AND SURFACE TROUGH WILL APPROACH THE REGION DURING
THE AFTERNOON AND INTO THE EVENING. THIS SYSTEM MAY RESULT IN SOME
SCATTERED SHOWERS MAINLY ACROSS THE CENTRAL ZONES SOUTH THROUGH
DOWNEAST. A WARM FRONT WILL APPROACH THE REGION FROM THE SOUTHWEST
SATURDAY NIGHT AND THEN BECOME NEARLY STATIONARY ACROSS THE REGION
IN THE ZONAL FLOW ALOFT. THIS FRONT WILL LIKELY BE THE FOCUS FOR
SOME SHOWERS OR LIGHT RAIN LATER SUNDAY AND INTO SUNDAY NIGHT. THE
FRONT WILL PUSH SOUTH ACROSS THE REGION AS A COLD FRONT ON MONDAY.
THIS WILL RESULT IN THE CHANCE FOR SHOWERS ESPECIALLY ACROSS THE
CENTRAL AND DOWNEAST AREAS.
&&

.LONG TERM /MONDAY NIGHT THROUGH THURSDAY/...
MODELS IN THE LONG TERM HAVE A BETTER HANDLE TODAY ON DEVELOPMENT
OF SURFACE AND UPPER LEVEL FEATURES BUT ARE STRUGGLING WITH TIMING
OF THESE SYSTEMS. USED HPC GUIDANCE AS A STARTING POINT AND MADE A
FEW MINOR MODIFICATIONS. TUESDAY INTO WEDNESDAY COULD SEE A
BREAK IN THE PRECIPITATION BETWEEN FRONTAL SYSTEMS WITH
THURSDAY HAVING ANOTHER CHANCE FOR SHOWERS AS LOW PRESSURE OVER
CANADA AND ASSOCIATED COLD FRONT MOVES IN FROM THE WEST.
&&

.AVIATION /13Z FRIDAY THROUGH TUESDAY/...
EXPECT WIDESPREAD IFR/LIFR CONDS AT ALL TERMINALS THROUGH EARLY THIS
MORNING IN LOW CEILINGS AND REDUCED VSBYS IN FOG. CONDS WILL THEN IMPROVE
TO MVFR/VFR LATE THIS MORNING. TSTMS ARE POSSIBLE AT ALL TERMINALS
ESP THIS AFTERNOON AHEAD OF AN APPROACHING COLD FRONT. CONDS WILL
IMPROVE TO VFR BEHIND THE FRONT TONIGHT ALTHOUGH SOME PATCHY FOG
COULD RESULT IN SOME MVFR CONDS AT TIMES OVERNIGHT.

VFR CONDS WILL PREVAIL SATURDAY...THEN EXPECT PERIODS OF MVFR CONDS
SATURDAY NIGHT THROUGH MON IN POSSIBLE SHOWERS. VFR WILL
PREDOMINATE BY TUESDAY AS HIGH PRES BUILDS ACROSS.
&&

.MARINE...
NEAR TERM: WITH SEAS LOWERING TO 5 FT WITH A 8 SECOND PERIOD HAVE
DROPPED SMALL CRAFT ADVISORY FOR SEAS FOR THE REMAINDER OF TODAY.
SEAS MAINLY DUE TO S SWELL FOR TODAY AND TONIGHT. EXTENSIVE FOG
WILL REDUCE VISIBILITIES TODAY THROUGH EARLY TONIGHT...WITH
IMPROVING VISIBILITIES IN THE WAKE OF THE FRONT LATER TONIGHT.
SHOWERS/THUNDERSTORMS WILL ALSO OCCUR TODAY THROUGH EARLY TONIGHT
IN ADVANCE OF THE COLD FRONT.

SHORT TERM: SEAS MAY APPROACH SCA LEVELS SUN NIGHT AND INTO MON.
