NWS New Orleans, LA wrote its last area forecast discussion before the first event at Jun 15, 12:35 AM CST, 11 hours 28 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NEW ORLEANS/BATON ROUGE LA 135 AM CDT SUN JUN 15 2003 ALMOST A CARBON COPY OF THE FORECAST EXPECTED THIS MORNING WITH NO MAJOR CHANGES IN THE PATTERN ANTICIPATED FOR THE NEXT FEW DAYS. HIGH PRESSURE ANCHORED OVER THE ATLANTIC CONTINUES TO AFFECT THE GULF COAST REGION WITH SOUTHERLY FLOW PERSISTING. A BROAD UPPER TROF AFFECTING THE SOUTHEAST STATES ALSO REMAINS FAIRLY STAGNANT WITH EMBEDDED DISTURBANCES CONTINUING TO TRAVERSE EASTWARD ALONG THE BASE. BOTH THE ETA AND THE GFS SUGGEST THIS PATTERN TO HOLD AT LEAST INTO MID WEEK BEFORE THE RIDGE OUT WEST EXPANDS ALLOWING THE UPPER TROF TO MOVE EASTWARD. IF THE GFS IS CORRECT IN THIS ANALYSIS...THIS MAY BRING A TEMPORARY HALT TO THE WET WEATHER CONDITIONS THAT HAS BEEN DOMINATING THE ENTIRE CWA/PWA. IN THE SHORT TERM...HEAVY RAINS REMAIN THE PRIMARY CONCERN TODAY AND MONDAY ALTHOUGH QPF GUIDANCE FROM HPC DOES NOT INDICATE ANY WIDESPREAD OR MAJOR PROBLEMS. PRELIM NUMBERS...
