AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TAMPA BAY RUSKIN FL 153 PM EDT TUE JUN 21 2011 .SHORT TERM (TONIGHT-THURSDAY)... THE MID/UPPER LEVEL RIDGE WILL REMAIN OVER FLORIDA THROUGH WEDNESDAY THEN DURING THURSDAY BECOMES SUPPRESSED SOUTHWARD SOME AS A TROUGH MOVES INTO THE EASTERN STATES. MEANWHILE AT THE SURFACE THE RIDGE AXIS WILL GENERALLY REMAIN ACROSS CENTRAL FLORIDA INTO THURSDAY WITH A SOUTH TO SOUTHWEST FLOW ACROSS THE NATURE COAST...LIGHT SOUTHERLY WINDS OVER THE CENTRAL ZONES AND A SOUTHEAST TO SOUTH FLOW ACROSS THE SOUTHERN AREAS. OVERALL FLOW WILL REMAIN LIGHT ENOUGH FOR THE WEST COAST SEA BREEZE TO DEVELOP EACH AFTERNOON. WEDNESDAY LOOKS TO BE SIMILAR TO TODAY WITH MID/UPPER LEVEL SUBSIDENCE AND DRY AIR PERSISTING LEADING TO RATHER LOW RAIN CHANCES. BEST CHANCES WILL CONTINUE ACROSS THE SOUTH WHERE SLIGHTLY MORE MOISTURE WILL REMAIN. THEN DURING THURSDAY DEEPER MOISTURE...PRECIPITABLE WATER 1.7 TO 1.9 INCHES... WILL MOVE NORTHWARD AND THIS COMBINED WITH DAYTIME HEATING AND INCREASING MOISTURE WILL LEAD TO SCATTERED AFTERNOON AND EVENING THUNDERSTORMS. DAYTIME HIGH TEMPERATURES WILL REMAIN ABOVE NORMAL FOR WEDNESDAY THEN RETURN TO CLOSER TO NORMAL ON THURSDAY AS ADDITIONAL CLOUDS AND PRECIPITATION ARE EXPECTED. OVERNIGHT LOWS WILL REMAIN NEAR TO A FEW DEGREES ABOVE NORMAL. .LONG TERM (THURSDAY NIGHT-TUESDAY)... THE GFS AND ECMWF HAVE CHANGED LITTLE SINCE YESTERDAY...INCREASING MY CONFIDENCE IN A PERIOD OF INCREASED CLOUD COVER AND UNSETTLED WEATHER. WHILE THE SYNOPTIC FEATURES OVER THE EASTERN HALF OF THE COUNTRY ARE HANDLED SIMILARLY ENOUGH...THERE IS A DIFFERENCE IN THE AMOUNT OF MOISTURE POOLED OVER THE WESTERN GULF ON FRIDAY. THE GFS IS MORE ROBUST AND HAS BEEN VERY CONSISTENT WITH THIS MOISTURE. THIS DEEP TROPICAL MOISTURE WILL BE TAPPED BY THE UPPER- LEVEL TROUGH MOVING SLOWLY EASTWARD TOWARD THE EAST COAST OF THE U.S. BY SUNDAY. THE DEPTH AND STRENGTH OF THE TROUGH AS WELL AS THE AVAILABLE MOISTURE IN THE WESTERN GULF WILL DETERMINE JUST HOW SHOWERY OUR WEATHER IS THROUGH THE END THIS WEEK. RIGHT NOW...IT LOOKS LIKE THE BEST MOISTURE CONVERGENCE OVER THE STATE WILL CONTINUE THROUGH SATURDAY...THEN MID-LEVEL HEIGHTS BEGIN TO RISE AS THE EASTERN U.S. TROUGH LIFTS OUT TO THE NORTH. THE FEED FROM THE DEEP TROPICAL MOISTURE GETS CUT OFF ON SUNDAY ALLOWING THE REGION TO RETURN TO MORE TYPICAL SUMMER-TIME SHOWERS AND THUNDERSTORMS...BUT PRECIPITABLE WATERS REMAIN BETWEEN 1.8 AND 2.1 INCHES SO EXPECT AFTERNOON SEA BREEZES TO BE QUITE ACTIVE. && .AVIATION... SOME PERIODS OF CIGS AROUND 4000 FEET ARE POSSIBLE OVER FMY AND RSW UNTIL THE LATE AFTERNOON HOURS...BUT IN GENERAL EXPECT VFR CONDITIONS SHOULD PREVAIL FOR THE NEXT 24 HOURS. SOME THUNDERSTORMS MAY LINGER THROUGH THE EARLY EVENING HOURS...BUT MAINLY TO THE EAST OF THE TERMINALS. && .MARINE... SURFACE HIGH PRESSURE WILL CONTINUE TO SUPPORT LIGHT WINDS WITH SEAS OF 2 FEET OR LESS OVER THE GULF WATERS FOR THE NEXT FEW DAYS. A SEA BREEZE WILL DEVELOP ALONG THE COAST WEDNESDAY AND THURSDAY AFTERNOON THEN THE OVERALL FLOW WILL BECOME SOUTH TO SOUTHWEST FRIDAY AND SATURDAY. && .FIRE WEATHER... NO FIRE WEATHER HIGHLIGHTS OVER THE NEXT FEW DAYS AS LOW LEVEL MOISTURE WILL GRADUALLY BE INCREASING KEEPING RELATIVE HUMIDITY VALUES ABOVE CRITICAL LEVELS. && .PRELIMINARY POINT TEMPS/POPS...
