Area forecast discussion, Aug 9, 2:21 PM EDT, 4 hours 22 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSONVILLE FL 221 PM EDT WED AUG 9 2000 SHORT TERM... UPPER FLOW PATTERN ACROSS THE CONTIGUOUS UNITED STATES WILL BECOME AMPLIFIED AS LARGE HIGH PRESSURE CENTER OVER THE SOUTHEAST STATES RETROGRADES WEST AND BLENDS WITH THE SECONDARY HIGH PRESSURE CENTER OVER THE CENTRAL PLAINS. THIS WILL RESULT IN A BROAD TROF DEVELOPING OVER THE EASTERN SEABOARD AS WELL AS BECOMING A MAJOR PLAYER WITH TROPICAL DEPRESSION NUMBER 4 NORTH OF THE BAHAMAS. REFER TO LATEST ADVISORY FROM THE TROPICAL PREDICTION CENTER. IN RESPONSE TO UPPER HIGH SHIFTING WEST...UPPER LEVEL WINDS OVER OUR REGION WILL SHIFT TO THE WEST THEN NORTHWEST...ADVECTING IN DRIER AND SOMEWHAT MORE STABLE AIR. A SURFACE LOW ASSOCIATED WITH THE AFOREMENTIONED TROF WILL SWING SOUTH INTO NORTHERN GEORGIA LATE FRIDAY WITH LOW LEVEL WINDS BECOMING MORE SOUTHERLY. THIS SHOULD PRECLUDE A DOMINANT SEA-BREEZE WITH GREATEST CONCENTRATION ACROSS THE INTERIOR PORTIONS OF THE CWA. FOR TONIGHT...EVENING WIDELY SCATTERED CONVECTION WILL GIVE WAY TO PARTLY CLOUDY SKIES. WEAK RIDGING NEAR THE SURFACE WILL AID IN PATCHY LATE NIGHT INTO EARLY MORNING FOG. THURSDAY AND THURSDAY NIGHT...EASTERLY WAVE OVER THE CARIBBEAN WILL SHIFT NORTHEAST INTO THE EASTERN GULF OF MEXICO. AT THE SAME TIME...DRIER AIR BEGINS TO FILTER INTO THE REGION FROM THE NORTHEAST. GREATEST COVERAGE OF SHOWERS AND THUNDERSTORMS WILL OCCUR OVER OUR WESTERN ZONES IN VICINITY OF EASTERLY WAVE AND HIGHEST PRECIPITABLE WATER VALUES. LOOK FOR ACTIVITY TO QUICKLY DISSIPATE WITH LOSS OF DAYTIME HEATING. TROPICAL DEPRESSION NUMBER FOUR BEGINS TO SHIFT NORTH BY THURSDAY NIGHT OVER THE CENTRAL FLORIDA OFFSHORE WATERS. FRIDAY...TROPICAL DEPRESSION NUMBER 4 IS FORECAST TO TRACK NORTHEAST OVER THE WESTERN ATLANTIC. GIVEN THIS FORECAST...MAY SEE SUFFICIENT SUBSIDENCE TO INHIBIT WIDESPREAD CONVECTION ACROSS FLORIDA ZONES. SURFACE FRONT IS PROGGED TO MOVE SOUTH INTO CENTRAL GEORGIA...THEREFORE WOULD EXPECT GREATEST COVERAGE TO OCCUR OVER GEORGIA ZONES. EXTENDED...SURFACE LOW AND ASSOCIATED FRONT WILL MEANDER SOUTH FRIDAY NIGHT INTO MONDAY FOR CHANCE OF MAINLY AFTERNOON INTO EVENING SHOWERS AND THUNDERSTORMS. COASTAL WATERS...SHOULD SEE INCREASE IN WIND/SEAS THROUGH THE PERIOD AS TROPICAL DEPRESSION NUMBER 4 SLOWLY EDGES WEST THEN TOWARDS THE NORTH. NO HEADLINES AT THIS TIME...HOWEVER WILL LIKELY SEE SMALL CRAFT EXERCISE CAUTION CONDITIONS OVER THE OFFSHORE WATERS BY LATE FRIDAY. THANKS FOR THE COORDINATION CALL MLB. PRELIM...
