NWS New Orleans, LA wrote its last area forecast discussion before the first event at Jul 31, 1:15 AM CST, 12 hours 15 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NEW ORLEANS/BATON ROUGE LA 215 AM CDT THU JUL 31 2003 THE MAIN CHALLENGE THIS MORNING IS DEALING WITH THE PROBABILITY FOR RAIN LATER TODAY. BOTH THE ETA AND THE GFS ARE CONSISTENT WITH NOW KEEPING MUCH OF THE UPPER LEVEL ENERGY ASSOCIATED WITH THE UPPER TROUGH AFFECTING THE EASTERN STATES NORTH OF THE FORECAST AREA. THIS IS ALSO REFLECTIVE IN THE NEW MET AND MAV GUIDANCE WHICH SUGGEST 40 PERCENT AT BEST FOR TODAY. FORECAST SOUNDINGS FROM THE MESOETA PAINT A SIMILAR PICTURE TO YESTERDAY WITH A LIMITED CAP IN PLACE UNDER THE INFLUENCE OF A MARITIME REGIME WHILE STEERING CURRENTS REMAIN GENERALLY OUT OF THE WEST. IN ADDITION...FORECAST TIME HEIGHTS FROM THE GFS MUCH OF THE MARITIME MOISTURE CONFINED BELOW 700 MB. WITH THIS SAID...WILL LIKELY LOWER POPS TO 40 PERCENT TODAY THINKING MUCH OF THE RAIN OVER LAND WILL DEVELOP MORE IN THE AFTERNOON UNDER A DIURNAL INFLUENCE SUPPORTED BY SEA BREEZE CONVERGENT BOUNDARIES. PAST TODAY...THE UPPER TROUGH OVER THE EASTERN SECTIONS OF THE U.S. SHOULD CONTINUE TO SLOWLY DEEPEN AS SUGGESTED BY NWP GUIDANCE. HOWEVER...MUCH OF THE ENERGY ASSOCIATED WITH THIS FEATURE LOOKS TO REMAIN PREDOMINANTLY NORTH OF THE FORECAST AREA. THE BERMUDA RIDGE AT THE SURFACE ALSO LOOKS TO REMAIN ENTRENCHED OVER THE GULF COAST REGION INTO THE NEW WEEK KEEPING THE FORECAST AREA UNDER A MARITIME INFLUENCE. ALL OF THIS SUGGESTS A FAIRLY STATUS QUO FORECAST WITH SCATTERED MAINLY AFTERNOON AND EVENING THUNDERSTORMS CONTINUING WITH TEMPERATURES HOVERING NEAR NORMAL LEVELS. PRELIM NUMBERS...
