NWS Tampa Bay, FL wrote its last area forecast discussion before the first event at Jul 19, 12:22 PM EST, 3 hours 8 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TAMPA BAY RUSKIN FL 122 PM EDT SUN JUL 19 2009 .SYNOPSIS...AN UPPER RIDGE OVER THE DESERT SOUTHWEST SPRAWLS TO THE SOUTHWESTERN GULF...A TROUGH EXTENDS FROM JAMES BAY TO THE NORTH CENTRAL GULF WATERS...AND AN ATLANTIC RIDGE REACHES ACROSS THE BAHAMAS TO CUBA. AT THE SURFACE...HIGH PRESSURE COVERS THE MISSISSIPPI AND OHIO VALLEYS WITH A STALLED FRONTAL BOUNDARY STRETCHING FROM EAST TX...ALONG THE GULF COAST AND NORTH FL...TO THE SE U.S. COAST. HIGH PRESSURE OVER THE ATLANTIC RIDGES WEST...THROUGH THE FL STRAITS AND ACROSS SOUTH FL. && .SHORT TERM (TONIGHT-TUESDAY)...CURRENT SYNOPTIC SETUP HAS AN UPPER LEVEL TROUGH ACROSS THE SOUTHEAST WITH AN ASSOCIATED FRONTAL BOUNDARY STALLING OVER NORTHERN FLORIDA AND A SURFACE RIDGE AXIS ACROSS SOUTHERN FLORIDA. WEST TO SOUTHWEST FLOW BETWEEN THESE FEATURES HAS SPARKED SHOWERS AND THUNDERSTORMS MOSTLY ACROSS THE NATURE COAST AND ADJACENT COASTAL WATERS SO FAR TODAY. EXPECT THE ACTIVITY TO CONTINUE LATER THIS AFTERNOON AND EVENING AS UPPER LEVEL ENERGY MOVES OVER THE AREA. THE GREATEST THREAT FROM THE STRONGER THUNDERSTORMS WILL BE LOCALLY HEAVY RAINFALL AND STRONG DAMAGING WINDS. THE UPPER TROUGH WILL GRADUALLY LIFT NORTH MONDAY AND TUESDAY AS HIGH PRESSURE IN THE ATLANTIC RIDGES OVER THE AREA. THE STALLING FRONTAL BOUNDARY WILL DISSIPATE AS SURFACE HIGH PRESSURE BEGINS TO LIFT NORTH ON MONDAY AND INTO TUESDAY. WINDS WILL BECOME EASTERLY FOR MONDAY AND TUESDAY...WITH AFTERNOON SEA BREEZE CIRCULATIONS BECOMING THE FOCUS FOR SCATTERED THUNDERSTORMS EACH AFTERNOON. HIGHS WILL RUN FROM THE UPPER 80S TO LOWER 90S. LOWS WILL BE IN THE UPPER 60S IN SOME SPOTS NORTH AND ELSEWHERE IN THE LOWER TO MID 70S. .LONG TERM (TUESDAY NIGHT THROUGH SUNDAY)... THE LONG TERM (TUES NIGHT) BEGINS WITH THE UPPER TROUGH CONTINUING TO PULL OFF TO THE NORTHEAST OF THE AREA. AT THE SURFACE...THE TROPICAL WAVE THAT WAS ORIGINALLY PROGGED TO MOVE TOWARDS THE SOUTHERN PENINSULA NOW LOOKS TO MOVE UP TO THE MID ATLANTIC REGION...STAYING FAR ENOUGH OFF THE EAST COAST OF FL TO NOT HAVE AN IMPACT TO OUR AREA. IT WILL...HOWEVER...MEAN DRIER AIR OVER WESTERN PORTIONS OF THE PENINSULA. PUSHED CHANCE POPS FURTHER INLAND ON WEDNESDAY IN ANTICIPATION OF THIS FEATURE...BUT AM HESITANT TO LOWER THEM TOO MUCH AT THIS POINT AS THERE IS STILL PLENTY OF MOISTURE FOR ANY SEA BREEZE BOUNDARY TO WORK WITH. RELATIVELY DRY AIR REMAINS OVER THE REGION ON THURSDAY...SO LOW END (30-40%) POPS CONTINUE ALONG WITH NEAR-NORMAL TEMPS. THE GFS STILL HINTS AT A BAND OF MOISTURE MAKING ITS WAY NORTH UP THE PENINSULA THIS WEEKEND...BUT A LITTLE TOO EARLY TO TELL HOW FAR NORTH IT WILL MAKE IT DUE TO A TROUGH THAT IS PROGGED TO START DIGGING INTO THE MS VALLEY AROUND THE SAME TIME. && .AVIATION... AN AREA OF SHOWERS AND THUNDERSTORMS OFFSHORE WILL MOVE TOWARDS THE TERMINALS IN THE NEXT FEW HOURS...AND THINK COVERAGE WILL BE GREAT ENOUGH TO INCLUDE TEMPO GROUPS FOR THIS AREA OF STORMS COMBINED WITH ANY TS THAT DEVELOP OVER LAND THE REST OF THIS AFTERNOON. BRIEF MVFR CONDITIONS POSSIBLE WITH HEAVIER SHOWERS/THUNDERSTORMS. ACTIVITY DIMINISHES AROUND/JUST AFTER SUNSET...AND A QUIET NIGHT EXPECTED WITH LIGHT WINDS. EXPECTING ANOTHER GOOD DAY FOR THUNDERSTORM DEVELOPMENT TOMORROW. MODELS INDICATE AN AREA OF SHOWERS AND THUNDERSTORMS EARLY IN THE MORNING MOVING TOWARDS THE COAST NEAR SARASOTA...AND HAVE INCLUDED SOME VICINITY SHOWERS AT MOST OF THE TERMINALS (ALONG WITH A CB REMARK DUE TO POSSIBILITY OF SOME ISOLD TSRA) IN THE EARLY MORNING. && .MARINE...LIGHT WESTERLY WINDS AND SMALL SEAS WILL PREVAIL UNTIL MONDAY NIGHT WHEN WINDS BECOME MORE EASTERLY AS HIGH PRESSURE BUILDS ACROSS THE AREA THROUGH TUESDAY...WITH LIGHT WINDS AND SEAS. MAIN CONCERN WILL BE SCATTERED AFTERNOON THUNDERSTORMS TODAY THROUGH TUESDAY. && .FIRE WEATHER...NO CONCERNS. && .PRELIMINARY POINT TEMPS/POPS...

THE ADDED UPPER ENERGY WILL ALLOW A FEW OF THESE STORMS TO BECOME STRONG TO SEVERE THIS AFTERNOON WITH STRONG WIND GUSTS...HAIL...FREQUENT DEADLY LIGHTNING AND HEAVY RAINS CAUSING PONDING ON ROADWAYS POSSIBLE.
