A weak upper level shortwave rotating around an upper level ridge west of the area moved into the area. When combined with a moist and unstable summer air mass, this was enough for a few thunderstorms to develop across the Florida panhandle with isolated hail and damaging winds.

NWS Tallahassee, FL wrote its last area forecast discussion before the first event at Jul 2, 12:30 PM CST, 58 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TALLAHASSEE FL 230 PM EDT SAT JUL 2 2011 .SYNOPSIS... AT 2PM EDT...RADAR INDICATED THAT GULF SEA BREEZE INITIATED EARLIER AND MORE ACTIVE THAN FORECAST. UPDATED ZFP ACCORDINGLY. SCATTERED SHOWERS AND THUNDERSTORMS WERE NOTED WERE STRONG PRODUCING GUSTY WINDS AND THIS WILL LINGER PAST SUNDOWN. AT UPPER LEVELS... THE LARGE SCALE LONGWAVE PATTERN CONTINUES TO BE MARKED BY A FLAT PATTERN WRN HALF AND HIGHLY AMPLIFIED PATTERN EAST HALF OF U.S. THIS IS HIGHLIGHTED BY VERY BROAD RIDGING PAC NW TO NRN ROCKIES...A STRONG AND AMPLIFIED UPPER RIDGE FROM GREAT LAKES SWWD TO CAROLINAS THEN H5 RIDGE ACROSS SRN PLAINS...4-CORNERS REGION AND CENTRAL/SRN CA. MID/UPPER HIGH WAS NOTED OVER THE MID MS VALLEY. FINALLY... A TROUGH WAS NOTED FROM LOW JUST OFF NJ WITH AXIS SSW DOWN WRN ATLC TO CAROLINAS. THIS PLACES LOCAL REGION IN DRY NNE FLOW WITH BELOW CLIMO PRECIP WATER VALUES INCREASING FROM SW-NE. IN FACT GUIDANCE CONTINUES TO SHOW VERY SHARP DEW POINT GRADIENT SW-NE BISECTING CWA. DURING THE SHORT TERM...NRN BRANCH OF RIDGING FORECAST TO DEAMPLIFY AS A SERIES OF SHORTWAVES MOVE ACROSS THRU TONIGHT AND ATLANTIC TROUGH BEGINS TO LIFTS. HOWEVER ITS IMPACT ON SRN PORTION AND LOCAL AREA WILL NEGLIGIBLE AS RIDGE CONTINUES TO STRENGTHEN ESPECIALLY ERN EDGE. WITH ATLC TROUGH LIFTING FURTHER ON SUNDAY AND MONDAY...SRN RIDGE WILL FLATTEN SOME AND RETROGRADE QUICKLY BUT EVENTUALLY FULL SCALE RIDGE WILL RE-AMPLIFY NORTHWARD OVER THE HIGH PLAINS/CNTRL ROCKIES. SOME WEAKNESSES WILL DEVELOP WITH RIDGE ALLOWING MORE IMPULSES TO DROP SWD. HOWEVER...SOME EASTWARD EXTENSION AND ASSOCD SUBSIDENCE WILL REMAIN OVER THE SE STATES...JUST TO OUR NORTH THRU MONDAY. THIS WILL CONTINUE TO PROVIDE REGION WITH E TO NE WINDS IN THE 100-700 MB LAYER. ON TUESDAY...A SERIES OF SHORT WAVES WILL CARVE OUT A NEW MEAN TROUGH POSITION OVER THE ERN STATES. ONE SHORT WAVE WILL DROP INTO THE NEW MEAN TROUGH THAT BEGINS TO DIG ACROSS EASTERN CANADA INTO NEW ENGLAND PUSHING A WEAKENING AND SOMEWHAT DIFFUSE FRONTAL BOUNDARY BACK SOUTHWARD TO A POSITION ACROSS N CENTRAL GA AND AL WHERE IT IS EXPECTED TO STALL. ALL THIS REFLECTED IN MODEL SOUNDINGS. I.E. GFS TAE WITH 1.58 INCH PWAT AT 18Z SAT DOWN TO 1.05 INCH PWAT 12Z TUE BEFORE IMPACT OF TROUGH BEGINS WITH PWAT RISING TO 1.48 INCH PWAT AT 18Z WED. AT LOWER LEVELS... ANALYSIS SHOWED A WEAK...QUASI-STATIONARY DIFFUSE FRONTAL SYSTEM FROM THE PIEDMONT...THROUGH CNTRL GA AND AL...AND EXTENDING SWD TO SE MS AND SE LA. ANALYSIS SHOWED IT EXISTS JUST S OF ABOVE H5 CAROLINAS-CA RIDGE AND SW OF H5 ATLC TROUGH AND WILL SERVE AS REGIONAL CONVECTION FOCUS. AHEAD OF THIS BOUNDARY...A WEAK LOW WAS NOTED JUST OFF FL EAST COAST THEN...WEAK HIGH CONTINUES OVER SRN MOST GA AND WESTERN FL PANHANDLE STRETCHING SOUTHWARD OVER THE ADJACENT GULF WATERS. MAIN LOCAL FOCUS WILL REMAIN SEA BREEZE DEVELOPMENT. BOUNDARY IS PROGGED TO DRIFT NWD INTO TOMORROW AS HIGH PRESSURE BUILDS NNE WITH A WEDGE DEVELOPING DOWN THE COAST. THIS WILL COMBINE WITH FL LOW TO MODESTLY INCREASE LOCAL PRESSURE GRADIENT AND WILL ALLOW FOR SOME NIGHTTIME ELY SURGES ACROSS MARINE AREA AND ERN MOST COUNTIES. THE WEDGE WILL ALLOW SOME HIGHER MOISTURE TO DROP SOUTH ON TUES...ALLOWING THE WEAK FRONT TO APPROACH FROM THE N. A TROPICAL WAVE PASSING WELL TO THE SOUTH MAY ALSO BRING AN UPTICK IN MOISTURE ACROSS OUR SE CWA. && .SHORT TERM...(TONIGHT THROUGH TUESDAY) TYPE 2 ELY SEABREEZE REGIME TO CONTINUE THRU MONDAY BEFORE PATTERN SWITCHES TO TYPE 4 LIGHT SWLY ON TUES. HIGH INLAND TEMPS UPPER 90S TO AROUND 100 DEGREES TODAY WILL GRADUALLY DROP TO LOW-MID 90S ON TUES. POP FOCUS ACROSS PANHANDLE FL AND ADJACENT SE AL TODAY WILL SHIFT TO MORE SUMMERLIKE SEABREEZE PATTERN ON TUES. WETTER NAM SEEMS TO BE DOING A BETTER JOB ON PICKING UP IMPULSES DROPPING DOWN RECENT EVE/NIGHTS..AND SHOWING IT AGAIN TONIGHT WITH ACTIVE CONVECTION WRN HALF OF CWA ON SUNDAY. AGAIN GFS BONE DRY THRU PERIOD. WILL LEAN TOWARD NAM MODEL IN FORECAST. TONIGHT...EXPECT SEABREEZE CONVECTION TO LINGER OVER MAINLY PANHANDLE PAST SUNDOWN. ALSO KEEPING A EYE ON UPSTREAM ACTIVITY. NMM4 AND 12Z NAM BULLISH ON APPARENTLY BRINGING CNTRL AL/GA CONVECTION SWWD (IMPULSE DROPPING DOWN IN TIGHT WEAKNESS BETWEEN ERN PERIPHERY OF SRN (ACROSS GA THEN SE ALA/WRN PANHANDLE COUNTIES...AND WRN PERIPHERY OF WRN ATLC) RIDGES 02Z-08Z TO COAST BY 12Z...LOCAL WRF AND GFS LESS BULLISH. WILL GO WITH 30-10% W-E POP GRADIENT. LOWS FROM MID-UPPER 60S SE BIG BEND/ADJACENT GA IN DRIEST AIR TO MID 70S PANHANDLE COAST. PATCHY LIGHT FOG SHOULD DEVELOP LATE ESPECIALLY IF ANY RESIDUAL MOISTURE LINGERS FROM EARLIER RAINS. ALSO..KEEPING AN EYE ON SMOKE ERN MOST GA COUNTIES. SUNDAY...40-10% W-E POP GRADIENT DAYTIME...20-10% AT NIGHT. HIGHS UPPER 80S COAST TO MID 90S INLAND. LOWS MID-UPPER 60S DRIER SE BIG BEND/ADJACENT GA TO MID 70S COAST. MONDAY...30-20% W-E POP GRADIENT DAYTIME...ISOLD POPS AT NIGHT. HIGHS AROUND 90 COAST TO MID 90S INLAND. TUESDAY...30% POPS AREAWIDE. HIGHS AROUND 90 COAST TO MID 90S INLAND. && .LONG TERM...(TUESDAY NIGHT THROUGH NEXT SATURDAY) BOTH THE GFS AND EURO AGREE THAT BY TUES NIGHT...A SERIES OF SHORT WAVES WILL HAVE CARVED OUT A NEW MEAN TROUGH POSITION OVER THE EASTERN U.S. NEXT WEEK...AS THE BROAD UPPER LEVEL RIDGE RETROGRESSES FURTHER WESTWARD. A WEAK AND SOMEWHAT DIFFUSE FRONTAL BOUNDARY WILL BE LOCATED FROM THE CAROLINAS ACROSS NORTH CENTRAL GEORGIA AND ALABAMA WHERE IT IS EXPECTED TO STALL. A SECOND SHORT WAVE WILL ARRIVE ON FRIDAY AND REINFORCE THE OLD FRONTAL BOUNDARY WHICH IS STILL EXPECTED TO REMAIN TO THE NORTH OF THE TRI-STATE AREA. THIS BOUNDARY WILL SERVE AS ONE FOCUS FOR DIURNAL CONVECTION WHICH WILL INCREASE AS HEIGHTS FALL OVER THE SOUTHEAST U.S. ANOTHER FOCUS FOR DIURNAL CONVECTION WILL BE THE SEABREEZE. IN ADDITION...BOTH MODELS HINT AT SOME KIND OF EASTERLY WAVE APPROACHING FLORIDA TOWARD THE END OF THE WEEK...WITH THE EURO BEING MORE AGGRESSIVE IN SPREADING INCREASING DEEP LAYER MOISTURE NORTHWARD. THE AREA SHOULD ALSO BE LESS VULNERABLE TO REMNANTS OF MCS'S THAT DEVELOP AND COME OVER THE TOP OF THE RIDGE NEXT WEEK...DUE TO THE LARGE SCALE PATTERN BECOMING SIGNIFICANTLY LESS AMPLIFIED. THE BOTTOM LINE FOR THE TRI-STATE AREA SHOULD BE AN UPWARD TREND IN CLOUDS POPS...AND A BIT OF A DOWNWARD TREND IN TEMPS...ESPECIALLY MAX TEMPS DUE PRIMARILY TO THE INCREASED CLOUDS AND SHOWERS. BY THE END OF THE WEEK EXPECT POPS TO APPROACH CLIMATOLOGICAL NORMALS...WHILE MAX TEMPS REMAIN A BIT ABOVE NORMAL. && .MARINE... THE RIDGE TO THE NORTH WILL PROVIDE GENERALLY EAST TO NORTHEAST WINDS TO THE MARINE AREA...EXCEPT FOR AN ONSHORE SEA BREEZE NEAR THE COAST EACH AFTERNOON AND EARLY EVENING. LATE TONIGHT...AND AGAIN LATE SATURDAY NIGHT...A BIT OF AN EASTERLY WIND SURGE MAY DEVELOP ACROSS APALACHEE BAY...CAUSING A BUMP IN WINDS AND SEAS THAT WILL SUBSIDE AFTER DAWN. WE STILL EXPECT CONDITIONS TO REMAIN BELOW EXERCISE CAUTION LEVELS. && .AVIATION... THE PRIMARY FOCUS FOR THUNDERSTORM ACTIVITY WILL BE ALONG AND JUST INLAND OF A LINE FROM KAAF TO KECP. MORE ISOLATED THUNDERSTORMS ALSO ARE EXPECTED IN SOUTHEASTERN ALABAMA THIS AFTERNOON AS WELL. THIS ACTIVITY HAS ALREADY BEGUN IN ERNEST AND WILL SUBSIDE IN THE EVENING AS IS TYPICALLY THE CASE. THUNDERSTORM ACTIVITY IS NOT EXPECTED TO BE SEVERE...HOWEVER VERY GUSTY WINDS MAY ACCOMPANY THESE STORMS AS THE LOW LEVELS OF THE ATMOSPHERE ARE VERY UNSTABLE. ELSEWHERE...HOT AND DRY CONDITIONS WILL PREVAIL THROUGH THE AFTERNOON AND EVENING. LATER TONIGHT...THERE IS AN OUTSIDE CHANCE FOR ISOLATED SHOWERS AND POSSIBLY A THUNDERSTORMS AFTER SUNSET MAINLY NORTH OF A LINE FROM KABY TO KDHN. THIS WILL BE ASSOCIATED WITH A WEAK AND STATIONARY FRONTAL BOUNDARY IN THAT AREA. REDUCTION OF VISIBILITY DUE TO SMOKE FROM WILDFIRES CONTINUES TO BE A PROBLEM FOR KVLD AND SURROUNDING TERMINALS. KVLD IS REPORTING 1SM THIS AFTERNOON. THIS IS LARGELY DUE TO A WIND SHIFT OUT OF THE EAST THAT OCCURRED LATE MORNING. THE SMOKE WILL LIKELY PERSIST THROUGH ABOUT 03UTC. ONCE THE NIGHTTIME INVERSION SETS UP WINDS WILL DECREASE AND CHANGE TO A MORE SOUTH DIRECTION. THIS WILL SHUT DOWN THE MOVEMENT OF THE SMOKE INTO THIS AREA. NONETHELESS...SOME SMOKE MAY REDUCE VISIBILITIES OVERNIGHT ALBEIT TO A LESSER EXTENT THAN THIS AFTERNOON. && .FIRE WEATHER... DEEP NORTHEASTERLY FLOW IS USHERING IN MUCH DRIER AIR INTO THE EASTERN HALF OF THE TALLAHASSEE FORECAST AREA. THIS IS EXPECTED TO CONTINUE THROUGH MONDAY. TO THE WEST...RETURN FLOW OFF THE GULF WILL KEEP CONDITIONS MORE MOIST COMPARED TO POINTS EAST. THEREFORE...THE EASTERN PORTION OF THE AREA WILL SEE MORE DETERIORATING CONDITIONS FROM A FIRE WEATHER PERSPECTIVE. MIXING HEIGHTS WILL BE ON THE INCREASE EACH DAY AS WILL TEMPERATURES. RELATIVE HUMIDITIES WILL DROP TO RED FLAG LEVELS FOR A SHORT PERIOD IN THE AFTERNOON. HOWEVER...WIND SPEEDS AND/OR ERC VALUES ARE NOT EXPECTED TO REACH CRITICAL LEVELS. AS SUCH WE SEE NO NEED FOR RED FLAGS AT THIS POINT. && .PRELIMINARY POINT TEMPS/POPS...
