AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TAMPA BAY RUSKIN FL 124 PM EDT WED JUL 28 2010 .SHORT TERM (TONIGHT THROUGH FRIDAY)... SURFACE HIGH CENTERED OVER SOUTHERN MS/AL THIS AFTERNOON...RIDGING BACK OVER SOUTHERN FLORIDA. WE'VE SEEN SOME ISOLATED STORMS DEVELOP OVER THE PAST HOUR OR SO...MAINLY EAST OF OUR FORECAST AREA...AND STILL EXPECTING SCATTERED SHOWERS/THUNDERSTORMS THIS AFTERNOON AND EVENING AS THE SEABREEZES SHIFT INLAND AND INCREASE ACTIVITY. TEMPS HAVE ALREADY CLIMBED INTO THE LOWER TO MID 90S BY NOON...AND ARE ON TRACK TO BE IN THE MID TO UPPER 90S BY EARLY AFTERNOON. ANYONE WORKING OUTSIDE THIS AFTERNOON WILL NEED TO TAKE PROPER PRECAUTIONS IN THIS HEAT...AS HEAT INDICIES SOAR INTO THE 105 TO 111 DEGREE RANGE. ACTIVITY WILL DIMINISH LATE TONIGHT...ALTHOUGH EXPECTING SCATTERED STORMS CONTINUING OFFSHORE OVERNIGHT AS IS TYPICALLY IN THIS TYPE OF PATTERN. THE UPPER HIGH SHIFTS FURTHER WEST TOMORROW AND THE SURFACE RIDGE IS SHIFTED EVEN FURTHER TO THE SOUTH (OVER EXTREME SOUTHERN FL). WITH A MORE WESTERLY FLOW...WE'D EXPECT THAT MUCH OF THE ACTIVITY WILL BE FOCUSED OVER WELL-INLAND LOCATIONS IN THE AFTERNOON/EVENING. PW PLOTS DEPICT BETTER MOISTURE PROFILES OVER INLAND LOCATIONS AS WELL... SO HAVE TAPERED POPS FROM 40% INLAND TO 30% ALONG THE COAST. TEMPS WILL CONTINUE TO RUN IN THE MID 90S. LATE THURSDAY INTO EARLY FRIDAY...A TROUGH SHIFTS INTO THE NORTHEASTERN UNITED STATES...AND DRAGS A FRONTAL BOUNDARY DOWN THROUGH THE DEEP SOUTH. LOOKS LIKE THIS BOUNDARY WILL STALL OVER NORTHERN FLORIDA BY FRIDAY MORNING...THEN REMAIN OVER SOUTHERN AL/GA/NORTHERN FL THROUGHOUT THE DAY ON FRIDAY. WE WILL BE SANDWICHED IN BETWEEN THIS FEATURE AND THE RIDGE TO THE SOUTH...GIVING US A SOUTHWEST FLOW...MEANING ACTIVITY WILL AGAIN BE FOCUSED INLAND AND OVER THE EASTERN PENINSULA. WITH SOME ADDITIONAL CLOUD COVER...TEMPS SHOULD MAX OUT AROUND 95 DEGREES OR SO INLAND...AND AROUND 90 DEGREES NEAR THE COAST (A DEGREE OR TWO COOLER THAN TODAY AND THURSDAY). .LONG TERM (FRIDAY NIGHT THROUGH WEDNESDAY)... MID/UPPER LVL TROUGH SWINGS BY THE NE STATES FRIDAY EVENING AND PUSHES A WEAKENING SURFACE BOUNDARY ACROSS THE SE STATES. THIS WILL BRING BEST CHANCES OF RAIN OVER EXTREME NORTHERN FLORIDA ON SATURDAY. FOR OUR AREA...SCATTERED/40 PERCENT CHANCE OF THUNDERSTORMS WILL BE IN PLACE SATURDAY AND SUNDAY AFTERNOON. UPCOMING GUIDANCE MAY BRING THE BOUNDARY FURTHER SOUTH...WHICH WILL REQUIRE BRINGING HIGHER POPS FOR THE WEEKEND...BUT THIS HAS NOT BEEN THE CASE FOR THE LAST COUPLE OF DAYS AS GFS/MOS REMAINS FAIRLY CONSISTENT WITH THE DESCRIBED FORECAST SOLUTION AND POPS IN THE UPPER 30S TO LOWER 40S. EARLY NEXT WEEK...THE SFC RIDGE BUILDS BACK AGAIN INTO THE PENINSULA WITH HOT DAYS AND WARM EVENING TEMPERATURES. A DRY AIRMASS WILL DESCEND UPON THE REGION AS A 500MB HIGH INTENSIFIES ACROSS TE SOUTHEASTERN U.S. AND THE EASTERN GULF. GUIDANCE STILL KEEP SOME 30 POPS FOR EACH AFTERNOON THROUGH WEDNESDAY...WHICH SEEMS REASONABLE TO KEEP ATTM DUE TO THE RETURNING SEA BREEZES/DAYTIME HEATING. && .AVIATION... VCTS COULD BRING PERIODS OF LOWERING CIGS TO AROUND 2500-3000 FEET AROUND THE TAF SITES AS SEABREEZES PUSH INLAND THROUGH THE LATE AFTERNOON HOURS. BUT IN GENERAL...EXPECT VFR CONDITIONS TO CONTINUE DURING THE NEXT 24 HOURS. && .MARINE... SURFACE HIGH PRESSURE CENTERED OVER THE NORTH CENTRAL GULF THIS AFTERNOON. A SLIGHTLY TIGHTER PRESSURE GRADIENT OVER THE NORTHEASTERN GULF IS PRODUCING SOME ELEVATED WINDS OVER OUR EXTREME NORTHERN OFFSHORE WATERS...IN THE 10 TO 15 KT RANGE. THIS SHOULD DIMINISH AS THE HIGH WEAKENS AND SHIFTS FURTHER WESTWARD. FLOW REMAINS WEST/SOUTHWEST THROUGH THE WEEKEND AS THE SURFACE RIDGE REMAINS TO OUR SOUTH...AND SPEEDS SHOULD GENERALLY REMAIN AROUND 10KTS OR LESS ALTHOUGH A SLIGHT INCREASE IS EXPECTED OVER THE OFFSHORE WATERS THIS WEEKEND AS THE PRESSURE GRADIENT INCREASES BETWEEN THE STATIONARY FRONTAL BOUNDARY TO THE NORTH AND HIGH PRESSURE TO THE SOUTH. && .FIRE WEATHER... HIGH RELATIVE HUMIDITIES EXPECTED THROUGHOUT MUCH OF THE FORECAST PERIOD. NO FIRE WEATHER CONCERNS. && .PRELIMINARY POINT TEMPS/POPS...
