AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MOBILE AL 259 AM CDT SUN AUG 19 2001 SERIES OF MID/UPPER LEVEL SHORTWAVES WILL CONTINUE TO MOVE ACROSS THE AREA THROUGH MONDAY. DIFFICULT TO PICK ANY PREFERRED AREA FOR PRECIP TODAY AND TONIGHT WITH SIGNIFICANT DIFFERENCES WITH THESE FEATURES IN MODELS SO WILL STAY WITH GOOD CHANCE POPS TODAY AND SLIGHT CHANCE TO CHANCE POPS TONIGHT. MODEL SOUNDINGS SHOW DRYING SLOWLY CONTINUING ALOFT AS THE UPPER TROF NEARS...SO ISOLATED STRONG/SEVERE STORMS ARE AGAIN POSSIBLE THROUGH THIS EVENING...MAINLY OVER INLAND ZONES NEAR WHERE SPC HAS OUTLOOKED A SLIGHT RISK AND DRIEST AIR IS EXPECTED TO EXIST ALOFT. AS THE H5 TROF MOVES ACROSS THE AREA ON MONDAY...A WEAKENING FRONT IS PROGGED TO MOVE NEAR THE GULF COAST PER THE AVN AND HPC WHILE THE ETA TAKES IT JUST INTO THE NORTHERN PORTION OF THE FORECAST AREA. WILL STAY WITH THE PREVIOUS SHIFTS THINKING AND LIMIT THE FRONTS SOUTHERN ADVANCE TO OVER OUR NORTHERN AREA BY MONDAY NIGHT. ALTHOUGH GENERAL DRYING OCCURS...MODEL SOUNDINGS STILL SHOW SUFFICIENT DEPTH OF MOISTURE THROUGH H8 TO SUPPORT CONVECTION FROM SEA BREEZE ACTIVITY AND ALONG THE WEAK FRONT. EXPECT COASTAL COUNTIES TO HAVE THE BEST COVERAGE...WHERE HIGHER CAPES AND BETTER MOISTURE DEPTH WILL BE LOCATED. ISOLATED SEVERE STORMS WILL AGAIN BE A RISK...BUT LOOKS TO BE MORE OVER THE SOUTHERN PORTION OF THE FORECAST AREA. EXTENDED RANGE...WILL HAVE TO CONTINUE TO MONITOR CHANTAL...BUT OTHERWISE CURRENT EXTENDED PACKAGE LOOKS GOOD FOR AUGUST CLIMO. FIRE AND MARINE...NO HIGHLIGHTS.
