Severe Thunderstorm Warning 23, NWS Caribou, ME

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CARIBOU ME
250 PM EDT MON AUG 1 2005

.SYNOPSIS...THE SMALL WAVE OF LOW PRESSURE THAT BROUGHT SHOWERS
TODAY WILL MOVE AWAY THIS EVENING. ANOTHER FAST MOVING WAVE OF LOW
PRESSURE WILL SLIDE THROUGH ON TUESDAY BRINGING A CHANCE OF SHOWERS
OR THUNDERSTORMS TO THE REGION. HIGH PRESSURE WILL SLOWLY BUILD DOWN
FROM THE NORTH WEDNESDAY AND THURSDAY AS LOW PRESSURE REMAINS OVER
THE MARITIMES.

&&

.UPDATE...
SOME SMALL THUNDERSHOWER CELLS ARE DEVELOPING IN OUR WESTERN CWA.
WILL INCLUDE CHC TSTMS THROUGH EARLY EVENING. BEST CHANCES FOR
THUNDER MAY BE CENTRAL DOWNEAST LOCATIONS.

.SHORT TERM (TONIGHT THROUGH THURSDAY)...THE SMALL SHORTWAVE THAT
BROUGHT SHOWERS...MOSTLY TO WESTERN AREAS...WILL BE MOVING AWAY
TONIGHT. SOME STRAY SHOWERS MAY STILL BE AROUND THIS EVENING BUT
MOST OF THE RAIN WILL BE OFF TO THE EAST. ANOTHER FAST MOVING WAVE
WILL BE SLIDING DOWN FROM THE NORTHWEST ON TUESDAY AS UPPER LEVEL
LOW PRESSURE DEEPENS TO OUR NORTH. SOME SCATTERED THUNDERSTORMS ARE
POSSIBLE WITH TUESDAYS SHORTWAVE DURING THE MIDDAY OR AFTERNOON.
STRONG 50KT JET ALOFT MAY RESULT IN GUSTY WINDS WITH ANY OF THOSE
STORMS SO INCLUDED CHC GUSTY TSTMS TUE. LOW PRESSURE WILL CONSOLATE
OVER THE MARITIMES TUESDAY NIGHT INTO WEDNESDAY AS HIGH PRESSURE
BEGINS TO MOVE DOWN FROM THE NORTH. STRONG NORTHWEST WINDS ALOFT
THROUGH MIDWEEK WILL MEAN WINDS MAY BECOME A BIT GUSTY DURING THE
MIDDAY HEATING AND MIXING EACH DAY. WENT A COUPLE DEGREES COOLER ON
TEMPS MOST OF THE PERIOD AS AIR WILL BE CHILLY ALOFT LIMITING
HEATING...BUT RIDGING WILL BRING A WARMUP ON THURSDAY.

&&

.LONG TERM (THURSDAY NIGHT THROUGH MONDAY)...
A RELATIVELY STRONG COLD FRONT WILL APPROACH FROM THE NORTHWEST
DURING FRIDAY MORNING THEN CROSS THE REGION IN THE AFTERNOON AND
EVENING. HIGH PRESSURE IS EXPECTED TO BUILD INTO NEW ENGLAND
SATURDAY THEN MOVE TO THE EAST OF THE REGION SUNDAY AND MONDAY.
HAVE INITIALIZED ALL EXTENDED GRIDS WITH HPC DATA. HAVE MANUALLY
MODIFIED MAX TEMPERATURES ACROSS THE COASTAL WATERS. SEA SURFACE
TEMPERATURES ARE RUNNING BETWEEN 50 AND 55 DEGREES AT 44034 AND
44027...SO DO NOT EXPECT MAX TEMPERATURES MUCH HIGH THAN UPPER
50S. HAVE ALSO MANUALLY MODIFIED SKY AND POP GRIDS TO BETTER FIT
THE PASSAGE OF THE COLD FRONT FRIDAY INTO EARLY SATURDAY. NO OTHER
CHANGES HAVE BEEN MADE TO THE HPC GRIDS.

&&

.AVIATION...CIGS GENERALLY MVFR TO IFR TONIGHT IN LOW CLOUDS. CIGS
MAY LIFT TO VFR ON TUESDAY BUT WATCH FOR THE RISK OF GUSTY
THUNDERSTORMS IN SOME SPOTS WHICH MAY LOWER CONDITIONS BRIEFLY TO
IFR DURING THE MIDDAY OR AFTERNOON TUESDAY.

&&

.MARINE...
WINDS GENERALLY SW AROUND 10 TO 15 KT TONIGHT INTO TUESDAY...BUT
LOCALLY HIGHER IN ANY TSTMS ON TUESDAY. WINDS WILL BECOME
NORTHWESTLY AROUND 10 KT TUESDAY NIGHT INTO WEDNESDAY...THEN BECOME
WESTERLY THURSDAY. DAYTIME BREEZES MAY BECOME A BIT GUSTY DUE TO
MIXING FROM STRONG JET ALOFT. SEAS WILL AVERAGE AROUND 3 FT THROUGH
THE PERIOD.

LONG TERM MARINE: HAVE POPULATED WIND GRIDS WITH HPC DATA. THIS
SEEMS TO BE VERY CONSISTENT WITH THE LIGHT WINDS EXPECTED IN THIS
PORTION OF THE FORECAST AS A RESULT OF THE STRONG MARINE LAYER.
FOR SEAS HAVE MANUALLY MODIFIED THE WNA WAVE WATCH. THE WAVE MODEL
IS TOO HIGH WITH COMBINED SEAS FRIDAY NIGHT. THIS SEEMS TO BE IN
RESPONSE TO THE GFS WHICH IS DEVELOPING A STRONG SOUTHERLY FLOW
AHEAD OF AN APPROACHING COLD FRONT. THIS DOES NOT SEEM REASONABLE
GIVEN THE MARINE LAYER WHICH SHOULD REMAIN STRONGLY IN PLACE.

&&

.CAR WATCHES/WARNINGS/ADVISORIES...
ME...NONE.
MARINE...NONE.
