Area forecast discussion, Aug 30, 2:05 PM EDT, 6 hours 54 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSONVILLE FL 205 PM EDT THU AUG 30 2001 CURRENTLY...HIGH PRES RIDGE AT THE SFC AND ALOFT CONTINUES OVER THE AREA. CU FIELD SLOW TO DEVELOP OVER EXTREME NE FL AND SE GA...DUE TO SLIGHT SUBSIDENCE ALOFT AND THICKER HI CLOUDS. MEANWHILE...A FEW SHOWERS BEGINNING TO FIRE IN THE SUWANNEE VALLEY AREA. W COAST SEABREEZE HAS MADE IT ABOUT 10 MILES INLAND WHILE E COAST BREEZE IS JUST BEGINNING TO MOVE INLAND. MODELS...ONLY REAL CHANGE IS THAT RIDGE SINKS A LITTLE FARTHER S AND WEAKENS SLIGHTLY. THIS ALLOWS A WEAK COLD FRONT TO APPROACH THE AREA FROM THE N. THIS FRONT SHOULD STALL OVER THE N PORTION OF OUR CWA. AVN DEVELOPS A FAIRLY STRONG LOW OVER THE MS VALLEY AND MOVE IT ALONG FRONT EARLY THIS WEEKEND...TENDING TO DRAG FRONT A LITTLE FARTHER S. THINK THIS IS UNLIKELY DUE TO THE NEARLY ZONAL FLOW AND LACK OF MUCH POTENT SHORTWAVE ENERGY. IN FACT...WEAK 500MB TROFFING CONTINUES BACK OVER THE MS VALLEY...AND THIS WOULD FURTHER PREVENT THE FRONT FROM PUSHING FARTHER S. PUBLIC...IN THE SHORT TERM...BELIEVE COVERAGE OF PRECIP THIS EVENING WILL BE SIMILAR TO YESTERDAY EVENING. COVERAGE MAY BE ENHANCED LATER BY A WEAK SHORTWAVE MOVING ACROSS GA. FRI PRECIP SHOULD ALSO BE SIMILAR...ALTHO THERE SHOULD BE MORE OF A W COMPONENT TO WIND FLOW. AS A RESULT...HIGHER POPS WILL BE SKEWED MORE TOWARD THE E COAST. SAT...WILL GO ABOVE CLIMO POPS AS FRONT APPROACHES. EXTENDED...COLD FRONT MAY BACKDOOR DOWN INTO NE FL BEFORE WASHING OUT...BUT SEE NO REASON TO MAKE ANY BIG CHANGES. MARINE...SW WINDS INCREASE LATE FRI...BUT THIS IN COVERED BY CURRENT PACKAGE. LITTLE CHANGE EXPECTED. PRELIM...
