NWS Tallahassee, FL wrote its last area forecast discussion before the first event at Jul 28, 1:51 PM EST, 1 hour 39 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TALLAHASSEE FL 251 PM EDT WED JUL 28 2010 .SYNOPSIS...VISIBLE SATELLITE AND SURFACE DATA CLEARLY DEPICT WHERE THE SURFACE RIDGE IS LOCATED...JUST SOUTH OF MOBILE BAY. THE CU FIELD HAS HAD DIFFICULTY FORMING AT ALL IN THE AREA JUST EAST OF THE RIDGE WHERE MOISTURE IN THE LOW AND MID LEVELS IS QUITE LIMITED TODAY. IN FACT...DEWPOINTS HAVE TAKEN A BIG DROP IN SOUTHEAST ALABAMA...DOWN INTO THE UPPER 60S. IT ALSO LOOKS LIKE THE INCREASING MOISTURE ALONG A WEAK BOUNDARY FROM ATLANTA TO ORLANDO IS LEADING TO THE DEVELOPMENT OF SCATTERED SHOWERS AND STORMS. TEMPERATURES HAVE RISEN QUICKLY TODAY WITH A FEW SITES ALREADY IN THE UPPER 90S. && .SHORT TERM...TONIGHT THROUGH FRIDAY NIGHT... A RIDGE OF HIGH PRESSURE CURRENTLY OFF TO OUR WEST NEAR SOUTHERN LOUISIANA WILL CONTINUE TO MOVE TOWARDS TEXAS. AS THE RIDGE TRACKS WESTWARD...A WEAK SURFACE TROF WILL SLIDE INTO OUR REGION THURSDAY AND AFTERNOON INSTABILITY WILL LEAD TO AN INCREASE IN POPS. HIGHEST POPS WILL MAINLY BE RESTRICTED TO THE FLORIDA BIG BEND AND EASTERN PORTIONS OF THE FLORIDA PANHANDLE. COVERAGE OF STORMS AWAY FROM THE COAST COULD BE MINIMAL DEPENDING ON THE AMOUNT OF DRY AIR LEFT BEHIND FROM THE RIDGE. AS THE TROF WASHES OUT ON FRIDAY...MORE OF A SEA BREEZE TYPE PATTERN WILL RESUME WITH THE INCREASED TROPICAL MOISTURE PRESENT. A LIGHT AND VARIABLE 1000-700MB FLOW WILL CREATE A TYPE 1 SEA BREEZE REGIME AND RESTRICT THE HIGHEST POPS NEAR COASTAL REGIONS OF THE CWA. A LAND BREEZE SHOULD DEVELOP IN THE OVERNIGHT HOURS OF THURSDAY AND FRIDAY...BUT LACK OF A LARGE LAND-SEA TEMPERATURE GRADIENT WILL LIMIT DEVELOPMENT. HEAT INDUCED STORMS SHOULD DISSIPATE OVER LAND MAINLY BEFORE MIDNIGHT...AND STORMS OVER NIGHT IN THE GULF SHOULD FIZZLE OUT JUST AFTER SUNRISE. HIGHS WILL BE IN THE MID TO UPPER 90S FOR INLAND REGIONS...AND UPPER 80S TO LOW 90S FOR COASTAL REGIONS. LOWS WILL DIP IN THE MID TO UPPER 70S. HEAT INDICIES WILL BE IN THE THE MID 100S. AREAS THAT RECEIVE PRECIPITATION WILL SEE LOWER HEAT INDEX VALUES. .LONG TERM (SATURDAY THROUGH WEDNESDAY)...THE LARGE SCALE PATTERN BEGINS RATHER AMPLIFIED HIGHLIGHTED IN NRN STREAM BY RIDGE OVER WRN HALF AND TROUGH OVER ERN HALF OF CONUS INTO WRN ATLC AND EXTENDING DOWN TO MID-ATLC SEABOARD. BY SUNDAY...TROUGH BEGINS TO MOVE OFFSHORE WITH RISING HEIGHTS DROPPING DOWN EAST COAST. IN SRN STREAM...BROAD RIDGE REMAINS ANCHORED BY 594DM HIGH OVER TX THRU WEEKEND BUT AS TROUGH MOVES OFFSHORE...HOT RIDGE OF HIGH PRESSURE BUILDS BACK EWD STRONGLY OVER THE SE WITH VERY DRY AIR RETURNING IN THE MID-LEVELS. EXPECT H5 TEMPS ONLY AROUND -2C. THUS LITTLE OVERALL CHANGE IS EXPECTED IN THIS HOT SUMMERTIME PATTERN UNTIL LATE TUES OR WED. LIGHT NLY FLOW AT UPPER LEVELS IS FORECAST THROUGH THE PERIOD. BY LATE TUES...582DM LOW DEVELOPS OFF VA/NC COAST AT BASE OF TROUGH. LOW THEN BECOMES CUTOFF FROM TROUGH OFF NC COAST ON WED SHUNTING SRN RIDGE FURTHER WWD. ASSOCD HIGHER LEVEL MOISTURE THEN ROTATES AROUND LOW AND ACROSS CWA. AT SURFACE...AS ERN UPPER TROUGH MOVES OFFSHORE THRU WEEKEND...WEAKENING FRONTAL BOUNDARY OVER SOUTHEAST STATES LOSES PUSH AND SURFACE RIDGE OVER SRN FL BEGINS TO MOVE BACK NWD. HOWEVER...GIVEN WEAK UPPER PUSH/DYNAMICS...DOUBTFUL FRONT WILL REACH CWA AND BOTH GFS AND ECMWF SHOW IT STATIONARY ACROSS S/CNTRL GA/ALA AT END OF PERIOD. SO RAIN WILL BE MAINLY FROM SHALLOW SEA-BREEZE INFLUENCES THRU DAY 5. WITH OFFSHORE STEERING FLOW MOST OF PERIOD...STRONG TO ISOLATED LATE DEVELOPING SEVERE STORMS CANNOT BE RULED OUT. BY DAY 6...FRONT WILL BE CLOSE ENOUGH TO PROVIDE SOME LIFT (OUTFLOW BOUNDARIES) SO WHEN COMBINED WITH DEEPER LAYER MOISTURE FROM ATLC PUSHED SWWD...EXPECT INCREASE IN CONVECTION. WILL DEEP LAYER RIDGE OVERHEAD...WE EXPECT HOT AND OPPRESSIVE CONDITIONS WITH HIGH HEAT INDICES TO PERSIST. EXPECT LOWS IN THE MID TO UPPER 70S AND HIGHS IN THE MID TO UPPER 90S...BOTH ABOUT 5-7 DEGREES ABOVE CLIMO (INLAND CLIMO IS AROUND 70/92). MAXIMUM HEAT INDICES EACH AFTERNOON ARE EXPECTED TO BE 105 TO 110 DEGREES WITH A FEW SPOTS POSSIBLY EXCEEDING 110 EACH DAY NECESSITATING A HEAT ADVISORY. WILL GO WITH WDLY SCT-LOW SCT POPS SAT...LOW SCT SUN THRU TUES AND MID SCT ON WED. && .AVIATION...THUNDERSTORM ACTIVITY IS FOCUSED ALONG THE I-75 CORRIDOR THIS AFTERNOON. HAVE INCLUDED VCTS FOR KABY AND KVLD. OTHERWISE...FEEL CB WILL SUFFICE. VFR CONDITIONS ARE EXPECTED TO PREVAIL THROUGH THE ENTIRE FORECAST PERIOD AT ALL TERMINALS. && .MARINE...AS THE PRESSURE GRADIENT TIGHTENS BETWEEN THE SURFACE RIDGE SOUTH OF THE MOUTH OF THE MISSISSIPPI RIVER AND A WEAK LOW PRESSURE TROF ACROSS THE SOUTHEAST COAST...WINDS WILL INCREASE TO NEAR 15 KNOTS AT TIMES TONIGHT OUT OF THE NORTHWEST. NO HEADLINES ARE EXPECTED...BUT THIS WILL INCREASE SEAS TO 3 FEET WELL OFFSHORE. EXPECT WINDS TO GRADUALLY DIMINISH THROUGH THURSDAY AS THIS GRADIENT SLOWLY RELAXES. && .FIRE WEATHER...THE HOT AND RELATIVELY DRY WEATHER WILL CONTINUE OVER THE NEXT SEVERAL DAYS. INCREASED TRANSPORT WINDS WILL ALSO INCREASE AFTERNOON DISPERSIONS. HOWEVER...MINIMUM HUMIDITY VALUES ARE FORECAST TO REMAIN ABOVE 40 PERCENT THROUGH FRIDAY. && .PRELIMINARY POINT TEMPS/POPS...
