AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TALLAHASSEE FL 253 PM EDT SUN MAY 16 2010 .SHORT TERM (TONIGHT THROUGH TUESDAY NIGHT)...UPPER RIDGE CONTINUES TO RETREAT TO THE EAST TODAY WHICH HAS ALLOWED FOR A DEEP SOUTHWESTERLY FLOW AND INCREASING DEEP LAYER MOISTURE. WITH THE AID OF AN APPROACHING WEAK SHORTWAVE...CONVECTION CONTINUES TO FIRE ALL ALONG THE NORTHERN GULF COAST. THE APPROACHING SHORTWAVE WILL ALLOW SOME CONVECTION TO CONTINUE OVERNIGHT ACROSS THE AREA AND HAVE KEPT POPS ELEVATED. THE SHORTWAVE IS FORECAST TO WEAKEN MONDAY...BUT WHAT REMAINS WILL MOVE ACROSS THE FORECAST AREA. THIS WILL PUSH THE HIGHEST RAIN CHANCES INTO THE EASTERN HALF OF THE FORECAST AREA...WITH THE WESTERN HALF DRYING OUT...ESPECIALLY IN THE AFTERNOON. BY TUESDAY...SHORTWAVE WILL EXIT WITH DRIER AIRMASS MOVING IN BEHIND A WEAK COLD FRONT. THIS WILL LIMIT ANY CONVECTIVE POTENTIAL SO VERY MINIMAL POPS IN THE GRIDS. HIGH TEMPS WILL WARM INTO THE UPPER 80S MONDAY OVER THE WESTERN HALF OF THE CWA BEHIND THE SHORTWAVE. THE EASTERN HALF WILL BE SEVERAL DEGREES COOLER WITH MORE SHOWERS AND CLOUD COVER.

WILL CONTINUE TO INDICATE LOW POPS WED THROUGH FRI WITH THE OLD FRONTAL BOUNDARY WELL TO THE SOUTH...THEN AS THE NEXT VIGOROUS SHORT WAVE LIFTS RAPIDLY NORTHWARD THROUGH THE MISSISSIPPI VALLEY TOWARD THE GREAT LAKES...RISING PRESSURES OFF THE MID ATLANTIC COAST WILL PRODUCE AN INCREASING EASTERLY FLOW ACROSS THE AREA...BRINGING A RETURN OF MOISTURE AND SOME INCREASE IN CLOUDS AND POPS. TEMPERATURES WILL RANGE FROM NEAR TO A LITTLE ABOVE NORMAL THROUGH THE PERIOD. && .AVIATION...ABUNDANT MOISTURE AND AN APPROACHING UPPER LEVEL TROUGH IS RESULTING IN SCATTERED SHOWERS AND EMBEDDED STORMS THIS AFTERNOON. THE CHANCE FOR THESE PASSING SHOWERS WILL CONTINUE INTO THE OVERNIGHT. AFTER MIDNIGHT...THE BETTER CHANCES FOR THE SHOWERS WILL MOVE EAST OF KDHH AND KPFN.

SOUTHWEST AND SOUTH CENTRAL GEORGIA...AND THE FLORIDA BIG BEND AND PANHANDLE...AND ADJACENT COASTAL WATERS. .DAY ONE...TODAY AND TONIGHT... ...THERE IS A MODERATE RISK OF RIP CURRENTS TODAY AND MONDAY ALONG THE BEACHES OF THE FLORIDA PANHANDLE AND BIG BEND... ...HEAVY RAINFALL MAY SPREAD ACROSS THE AREA FROM WEST TO EAST TODAY THROUGH MONDAY WITH STORM TOTAL AMOUNTS OF 2 TO 4 INCHES OR PERHAPS A BIT HIGHER WILL BE POSSIBLE AT THIS TIME... AN AREA OF LOW PRESSURE NEAR THE GULF COAST IS ALREADY PRODUCING A COUPLE OF FAIRLY LARGE AREAS OF HEAVY SHOWERS AND THUNDERSTORMS OVER SOUTHERN ALABAMA AND THE WESTERN FLORIDA PANHANDLE...WHICH WILL LIKELY SPREAD EASTWARD ACROSS THE REGION TODAY AND LINGER INTO MONDAY. ALTHOUGH NO SEVERE THUNDERSTORMS ARE EXPECTED WITH THIS SYSTEM...THERE IS A GROWING CONCERN FOR A POTENTIAL WIDESPREAD HEAVY RAINFALL EVENT ACROSS THE REGION. ALTHOUGH 6 HOUR FLASH FLOOD GUIDANCE AMOUNTS FROM THE RIVER FORECAST CENTER ARE VERY HIGH (IN THE 5 TO 7 INCH RANGE)...IF WE WERE TO APPROACH THESE LEVELS OVER MORE THAN A FEW ISOLATED AREAS...THE POTENTIAL FOR SIGNIFICANT RIVERINE FLOODING MUST BE WATCHED CLOSELY...AS MANY AREA RIVERS ARE STILL AT FAIRLY HIGH LEVELS...BUT BELOW FLOOD STAGE. .DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY... AFTER THE RAINFALL EXITS THE AREA ON MONDAY OR MONDAY NIGHT...FAIR AND DRIER CONDITIONS WILL QUICKLY RETURN TO THE REGION ON TUESDAY AND WEDNESDAY. THEREAFTER...THE MODEL SOLUTIONS DIVERGE AND FORECAST CONFIDENCE BECOMES SOMEWHAT LOW. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION SHOULD NOT BE NEEDED TODAY...BUT ANY ACCURATE RAINFALL REPORTS WILL BE VERY WELCOME.
