NWS Tallahassee, FL wrote its last area forecast discussion before the first event at Aug 21, 7:25 AM CST, 6 hours 4 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TALLAHASSEE FL 925 AM EDT SAT AUG 21 2010 .UPDATE (TODAY AND TONIGHT)... 13Z WATER VAPOR AND H4 RUC ANALYSIS SHOWING ELONGATED AND BROAD RIDGING IN CONTROL OF THE SOUTHERN TIER OF THE COUNTRY...INCLUDING THE NORTHERN GULF COAST. THE STRETCH OF VERY HIGH MOISTURE LEVELS JUST WON'T QUIT...WITH THE 12Z KTLH SOUNDING PROFILE SHOWING A PWAT VALUE OF AROUND 2.4". OTHER FEATURE OF INTEREST TO OUR FORECAST IS A WELL DEFINED SHORTWAVE PASSING OVER THE MIDDLE MS VALLEY. THIS FEATURE IS PROGGED TO MOVE EAST AND SOUTHEAST TOWARD THE MID-ATLANTIC AND CAROLINA COASTLINES THROUGH TOMORROW MORNING. THIS MOTION WILL ACT TO BREAK DOWN THE RIDGING OVER THE SOUTHEAST. AT THE SURFACE...BROAD RIDGING REMAIN IN CONTROL OVER MUCH OF THE GULF AND EASTWARD OVER THE FLORIDA PENINSULA. WELL TO OUR NORTHWEST...WE FIND A COLD FRONT EXTENDING FROM EASTERN OKLAHOMA ACROSS MISSOURI. THIS FRONT IS ASSOCIATED WITH THE SHORTWAVE MENTIONED ABOVE. AS THE UPPER LEVEL ENERGY MOVES EASTWARD...THIS FRONT WILL FOLLOW...AND DIG SOUTHEAST TOWARD NORTHERN AL AND GA TOMORROW MORNING. FOR THE REST OF TODAY...1000-700MB FLOW IS FROM THE WNW/NW. THIS FLOW ENHANCED THE LAND BREEZE THIS MORNING...AND RESULTED IN NMRS SHOWERS AND STORMS ACROSS THE COASTAL WATER. THIS CONVECTION HAS BEEN PUSHING EASTWARD AND INTO THE COASTAL ZONES ALONG THE EASTERN SIDE OF APALACHEE BAY...ESPECIALLY DIXIE COUNTY. ELSEWHERE WE ARE STARTING THE DAY OFF ON THE DRY SIDE. THE DRY CONDITIONS SHOULD HOLD FOR AT LEAST A FEW MORE HOURS AWAY FROM THE COAST AS THE NW FLOW SLOWS THE SEA-BREEZE DEVELOPMENT AND INLAND PENETRATION. HOWEVER...EVENTUALLY BY EARLY THIS AFTERNOON...THESE SEA-BREEZES WILL DEVELOP...AND WITH THE HIGH MOISTURE LEVELS...STILL EXPECT SCT-NMRS SHOWERS/STORMS TO BEGIN DEVELOPING. WITH THESE DEVELOPING SEA-BREEZES...CONVERGENCE OVER THE COASTAL WATERS WILL DECREASE AND ALLOW CONDITION TO IMPROVE DURING THE AFTERNOON HOURS. TONIGHT...LAND BASED EVENING SHOWERS AND STORMS WILL BEGIN TO DECREASE IN COVERAGE AND INTENSITY WITHIN A FEW HOURS OF SUNSET. HOWEVER...IN TYPICAL FASHION...CONVECTION WILL BEGIN TO RAMP BACK UP AGAIN OVER THE COASTAL WATERS AFTER MIDNIGHT...AND ESPECIALLY TOWARD SUNRISE. AS WAS THE CASE THIS MORNING...THE FLOW SHOULD PUSH THESE SHOWERS EASTWARD TOWARD THE TAYLOR AND DIXIE COUNTY COASTS. && .AVIATION... A FEW PATCHES OF LOW CLOUDINESS ARE STUBBORNLY HANGING ON AT ABY...TLH...AND VLD THIS MORNING...BUT ALL OF THE OTHER TERMINALS ARE NOW AT VFR. ABY AND VLD SHOULD ALSO BECOME VFR BY OR SHORTLY AFTER 14Z THIS MORNING...AND THE NEXT CONCERN FOR TODAY WILL BE TIMING THE DEVELOPMENT OF THE SHOWERS AND THUNDERSTORMS. ALTHOUGH A COLD FRONTAL BOUNDARY IS DEVELOPING TO OUR NORTHWEST...THIS SHOULD BE A FACTOR TO OUR SENSIBLE WEATHER ON SUNDAY AND MONDAY. THEREFORE...WE EXPECT THE SEA BREEZE TO STILL BE THE PREDOMINANT MECHANISM FOR CONVECTIVE DEVELOPMENT OVER THE AREA TODAY...WHICH WOULD SUGGEST A GENERAL SOUTH TO NORTH PROGRESSION OF THE SHOWERS AND THUNDERSTORMS AT THE TERMINALS AS THE DAY WEARS ON. && .MARINE... WEST TO SOUTHWEST FLOW AT 10 TO 15 KNOTS WILL HOLD THROUGH THIS EVENING WITH SEAS RUNNING AROUND 2 FEET (1-2 FEET IN APALACHEE BAY). FLOW IS FORECAST TO VEER AROUND TO THE NORTHWEST TONIGHT AS HIGH PRESSURE RETREATS WESTWARD TOWARD THE CENTRAL AND WESTERN GULF OF MEXICO. SCT-NMRS SHOWERS AND STORMS THIS MORNING SHOULD DECREASE IN COVERAGE FOR THE AFTERNOON AND EVENING HOURS...BEFORE RE-DEVELOPING LATE TONIGHT AND SUNDAY MORNING. && .FIRE WEATHER...WITH PLENTIFUL GULF MOISTURE AND WIDESPREAD SHOWER AND THUNDERSTORM ACTIVITY...RELATIVE HUMIDITIES WILL REMAIN ABOVE CRITICAL LEVELS AND NO FIRE WEATHER CONCERNS ARE ANTICIPATED INTO THE UPCOMING WORK WEEK. && .PRELIMINARY POINT TEMPS/POPS...
