AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NEW ORLEANS/BATON ROUGE LA 330 AM CDT TUE AUG 13 2002 LATEST UPPER AIR ANALYSIS ALONG WITH MODEL GUIDANCE FOR THE NEXT SEVERAL DAYS SUGGEST THE BROAD WEAK TROUGH OVER THE SOUTHERN PLAINS TO REMAIN NEARLY STATIONARY WHILE MINOR SPOKES OF ENERGY (VORT LOBES) ROTATING THROUGH THE BOTTOM OF THE TROUGH ACROSS THE LOWER MS VALLEY. THE AIRMASS REMAINS VERY TROPICAL OVER THE REGION AND UNSTABLE WITH PWS ABOVE 2 INCHES AND K-VALUES 34 OR HIGHER. THE LOWER MS VALLEY IS IN THE HEART OF VERY HIGH THETA-E VALUES TOO. IN THE 4 TO 7 DAY PERIOD THIS UPPER TROUGH RETROGRESSES A BIT TO THE WEST SO THAT THE POPS OVER THE REGION MAY DROP BACK TO NORMAL OR BELOW. IN THE MEANTIME LOCALLY HEAVY RAIN IS LIKELY OVER THE CWA DUE HIGH PWS AND SLOW MOVING STORMS. SOME AREAS MAY RECEIVE 2 TO 3 INCHES THROUGH WEDNESDAY...MOSTLY OCCURRING IN THE DAYTIME HOURS WHERE HEATING IS A FACTOR. IN A NUT SHELL THE WET WEATHER PATTERN SHOULD CONTINUE SEVERAL MORE DAYS. THE AVN MODEL CONTINUES TO BE THE SUPERIOR MODEL. HOWEVER TODAY THE NGM AND ETA MODELS ARE COMING MORE IN LINE WITH THE AVN. PRELIMINARY NUMBERS FOLLOW...
