AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOBILE AL
326 AM CDT SUN OCT 5 2008

.SHORT TERM (TODAY AND TONIGHT)...SURFACE HIGH PRESSURE OVER THE
EASTERN GREAT LAKES...RIDGED SOUTHWESTWARD ACROSS FORECAST AREA WILL
MAKE FOR ANOTHER WARM AND RAINFREE DAY. PRECIPITABLE WATER VALUES
REMAIN UNDER AN INCH OVER THE FORECAST AREA. HIGH TEMPERATURES
SATURDAY WERE WITHIN A DEGREE OR TWO OF GUIDANCE AND WILL LIKELY BE
THE SAME AGAIN TODAY...GENERALLY MID 80S FOR HIGHS UNDER SUNNY
AFTERNOON SKIES. /11

.LONG TERM (MONDAY THROUGH SATURDAY)...UPPER LEVEL TROF OVER THE
SOUTHERN PLAINS ON MONDAY MOVES SLOWLY EASTWARD THROUGH MID WEEK.
AHEAD OF THIS SYSTEM...GULF MOISTURE OPENS UP WITH PRECIPITABLE
WATERS INCREASING TO 1.5 INCHES TUESDAY AND WEDNESDAY. THE EASTWARD
PROGRESSION OF THE UPPER TROF BRINGS A WEAK COLD FRONT OR SURFACE
TROF THROUGH THE AREA MID WEEK. CONSIDERING THE APPROACH OF THESES
FEATURES...ENOUGH DEEP LAYER LIFT OPERATES ON AN INCREASED DEEP LAYER
MOISTURE PROFILE TO BRING A CHANCE OF SHOWERS AND THUNDERSTORMS TO
THE REGION TUESDAY THROUGH EARLY WEDNESDAY. NOT ANTICIPATING ANY
PROBLEMS WITH REGARD TO SEVERE WEATHER WITH THIS MID WEEK SYSTEM. THE
LATEST RUNS OF THE ECMWF...GFS AND CANADIAN SHOW AN EASTWARD
PROGRESSION OF THE UPPER LEVEL HEIGHT FIELD INTO THE SOUTHEAST ON
THURSDAY. THIS MEANS THE BEST LIFT WILL BE LIFTING OUT OF THE AREA
AND HAVE REMOVED THE CHANCES OF PRECIPITATION THEN. ALTHOUGH...THE NEXT
UPPER LEVEL TROF DIGS INTO THE PLAINS NEXT WEEKEND...HAVE HELD OFF ON
INTRODUCING NEXT RAIN CHANCE UNTIL JUST BEYOND THIS FORECAST CYCLE AS
THE BEST MOISTURE AND LIFT WITH THIS NEXT SYSTEM LOOKS TO REMAIN
WEST OF THE AREA ON SATURDAY. AS FOR TEMPERATURES...THE NEW MOS
NUMBERS LOOKED TO BE A FEW DEGREES TO WARM ACROSS THE BOARD FOR
THURSDAY. HAVE DECIDED TO TRIM THESE BACK...EDGING CLOSER TO THE
ENSEMBLE MEAN FOR THURSDAYS HIGHS. NIGHTTIME TEMPERATURES RANGE FROM
UPPER 50S/LOWER 60S INTERIOR TO MID/UPPER 60S BEACHES. HIGHS
LOWER/MID 80S. /10

&&

.AVIATION (FOR 12Z ISSUANCE)...EXPECT TO CONTINUE VISUAL FLIGHT
RULES (VFR) FOR THE NEXT 24 HOURS...EXCEPT FOR SOME MARGINAL VFR
CONDITIONS AROUND SUNRISE DUE TO LIGHT FOG. WILL BE SOME CLOUDS
AROUND LATER TODAY...BUT SHOULD BE SCATTERED AND ABOVE 4000 FEET OR
SO. EASTERLY WINDS...SLIGHTLY STRONGER NEAR THE COAST...10 TO 15 MPH
WILL DEVELOP LATER THIS MORNING AND CONTINUE UNTIL SUNSET. /11

&&

.MARINE...OVER THE MARINE AREA...ESPECIALLY BEYOND 15 MILES OR SO
OFFSHORE...IS IN A TIGHTER PRESSURE GRADIENT BETWEEN THE RIDGE AND A
TROUGH FROM THE YUCATAN ACROSS SOUTH FLORIDA. EASTERLY WINDS IN THE
SOUTHERN SECTIONS OF THE MARINE FORECAST AREA HAVE BEEN 15 TO 20
KNOTS AND WILL CONTINUE FOR A FEW DAYS. AS A RESULT THE WAVE HEIGHTS
WERE 4 TO 6 FEET. THESE CONDITIONS ARE JUST BELOW SMALL CRAFT
ADVISORY LEVELS. FORECAST WILL CALL FOR EXERCISE CAUTION. ADVISORIES
WILL BE REQUIRED IF WAVES OR WINDS INCREASE. WINDS WILL DIMINISH A
BIT AS FLORIDA TROUGH WEAKENS THE FIRST OF THE WEEK BUT ANOTHER WEAK
TROUGH WILL APPROACH FROM THE WEST BY MID WEEK WITH EASTERLY WINDS
INCREASING TUESDAY NIGHT AND BECOMING SOUTH AS THE TROUGH AND
ASSOCIATED FRONT STALLS OVER THE AREA. SYSTEM GETS A PUSH TO THE EAST
ON THURSDAY WITH WINDS BECOMING NORTH AND NORTHWEST. /11

&&

.FIRE WEATHER...NO HEADLINES. LOWEST DAYTIME HUMIDITY FIELDS WILL
SHOW A MODERATING TREND OVER THE NEXT TWO DAYS. LOWEST NUMBERS NORTH
OF THE COAST TODAY WITH GRIDDED HUMIDITIES RANGING FROM 35 TO 40%. /10
