WEST CENTRAL AND SOUTHWEST FLORIDA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TAMPA BAY AREA - RUSKIN FL 314 PM EDT SAT JUL 27 2002 AN UPPER LOW OVER HISPANOLA IS MOVING WEST...SIMILAR TO AN AVN SOLUTION. DRY MID AND UPPER LEVEL AIR WILL STRETCH ACROSS THE SOUTHERN COUNTIES. THE UPPER LOW IS RAPPING SOME MOISTURE AROUND IT THAT HAS NOW WORKED INTO THE NORTHERN BAHAMAS. MODELS WASH OUT THE DRY AIR SO I WILL DECREASE POPS ONLY A LITTLE INLAND AND IN THE SOUTH. THE CONVECTION OVER THE GULF THAT HAS BEEN GROWING IN AREAL COVERAGE ALL DAY LONG SEEMS TO BE ASSOCIATED WITH SOME UPPER DIFLUENCE. THIS SHOULD MOVE WESTWARD AS THE UPPER LOW PUSHES WEST. THEREFORE OTHER THAN INCREASED ACTIVITY OVER THE SOUTHERN COASTAL WATERS TONIGHT IT WILL HAVE LITTLE IMPACT ON OUR AREA. MONDAY...SOME MOISTURE RETURNS AND I SLOWLY UP THE POPS A LITTLE. AN EASTERLY WAVE STARTS TO SPREAD DEEP MOISTURE BACK ACROSS THE STATE LATE MONDAY BUT MORE LIKE TUESDAY. THE RIDGE AXIS STAYS OVER NORTH OR CENTRAL FLORIDA THROUGH TUESDAY WHICH WILL KEEP THE BEST LOW LEVEL CONVERGENCE ALONG THE WEST COAST. BY WEDNESDAY A FRONT WANTS TO PUSH INTO GEORGIA...NUDGING THE SUBTROPICAL RIDGE SOUTHWARD. WEDNESDAY WILL BE THE TRANSITION DAY... BUT BY THURSDAY WE WILL BE SOLIDLY INTO THE WESTERLIES. I WILL REMOVE TIMING OF CONVECTION FROM THE FORECAST AND INCREASE LOW TEMPERATURES AND DECREASE HIGHS ALONG THE COASTAL AREAS FOR THURSDAY THROUGH SATURDAY. PRELIMINARY NUMBERS...
