SOUTH FLORIDA AREA FORECAST DISCUSSION...CORRECTED FOR RIGHT HOLIDAY NATIONAL WEATHER SERVICE MIAMI 235 PM EDT SAT MAY 24 2003 .TONIGHT THROUGH MONDAY NIGHT... NOT MUCH CHANGES FROM PREVIOUS FORECAST. MODELS IN FAIR AGREEMENT THROUGH SUNDAY WITH THE GFS THE FAVORED ONE. GFS HAS BEEN PERFORMING THE BEST ESPECIALLY ON THE WINDS WITH EVENTS TRANSPIRING OVER THE PAST COUPLE OF DAYS. IN THE UPPER LEVELS, LARGE MID/UPPER LEVEL LOW REMAINS OVER THE GREAT LAKES REGION AND AT THE SAME TIME THROUGH THE COURSE OF THE PERIOD, RIDGING BUILDS IN OVER THE ROCKIES TO OUR WEST AND ALSO ATLANTIC RIDGE BUILDS IN FROM THE EAST OVER SOUTH FLORIDA. AT THE SURFACE, OLD TROUGH BOUNDARY CONTINUES TO WASH OUT ACROSS SOUTH CENTRAL FLORIDA. WHAT ALL OF THIS MEANS IS THAT WE SHOULD SEE A DAY TO DAY DECREASE IN AFTERNOON TSRA ACTIVITY THROUGH MEMORIAL DAY. GOOD NEWS FOR OUTDOOR INTERESTS. .TUESDAY THROUGH SATURDAY... RIDGING OVER THE ROCKIES CONTINUES TO AMPLIFY THROUGH THURSDAY AND THIS ALLOWS GREAT LAKES LOW TO BEGIN MOVING TO THE SOUTHEAST. THIS IN TURN ERODES THE ATLANTIC RIDGE AND ONCE AGAIN LOWERS 50H OVER SOUTH FLORIDA DESTABILIZING ATMOSPHERE. HOWEVER...EACH SUCCESSIVE MODEL RUN DIFFERS ON THE TIMING AND STRENGTH OF ANY TYPE OF PUSH. ONE RUN SUGGESTS DRIER AIR PUSHING IN FROM THE NORTH WITH THE GREAT LAKES LOW MOVING SOUTHEASTWARD AND THE NEXT RUN WILL SHOW MOISTURE RETURNING UNTIL ABOUT THURSDAY. THEN BY FRIDAY MORE CONSISTENT WITH THE DRIER AIR. AT THIS TIME, COULD HAVE AN INCREASE AGAIN IN TSRA FOR TUESDAY THROUGH THURSDAY BUT WILL JUST LEAVE SCATTERED FOR NOW. THEN GO BACK TO SLIGHT CHANCE FOR FRIDAY AND SATURDAY. .MARINE... SURFACE GRADIENT REMAINS WEAK AND GETS EVEN LESS BY SUNDAY NIGHT THROUGH THURSDAY. SO, WITH THE EXCEPTION OF POSSIBLE SHRA/TSRA FOR MARINERS TO WORRY ABOUT SEAS WILL REMAIN QUITE LOW THROUGH THE PERIOD. .FIRE... NO PROBLEMS FORESEEN.
