NWS New Orleans, LA wrote its last area forecast discussion before the first event at Jun 6, 10:10 AM CST, 3 hours 20 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NEW ORLEANS/BATON ROUGE LA 1110 AM CDT SUN JUN 06 2004 .UPDATE...MAIN FORECAST PROBLEM FOR THIS UPDATE IS WHAT TO DO WITH THE FLOOD WATCH. RADAR SHOWS MID LEVEL SHORTWAVE TROUGH AND ASSOCIATED MID/UPPER DIVERGENCE AREA MOVING ACROSS COASTAL MS AND THE AL COASTAL WATERS WITH THE STRONGEST CONVECTION SHIFTING EAST OF THE FORECAST AREA. SUBSIDENCE ON THE BACK SIDE OF THIS FEATURE IS SUPPRESSING CLOUD COVER SOUTH AND WEST OF LAKE PONTCHARTRAIN. THIS IS ALLOWING TEMPERATURES TO APPROACH THE CONVECTIVE TEMPERATURE AROUND 85 DEGREES. WATER VAPOR IMAGERY AND UPPER AIR ANALYSIS SHOWS A WELL DEFINED VORT MAX OVER SOUTH CENTRAL LA MOVING SLOWLY EAST. THIS FEATURE...ALONG WITH INTENSE SURFACE HEATING AND SURFACE MOISTURE FLUX ADVECTION...SHOULD ALLOW FOR SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS WITH LOCALLY HEAVY RAINFALL THIS AFTERNOON. FLASH FLOOD GUIDANCE IN SOUTHWEST MS AND SOUTHEAST LA IS GENERALLY 1 TO 1.5 INCHES IN ONE HOUR AND 1.5 TO 2.2 INCHES IN 3 HOURS. THERE COULD BE ISOLATED RAINFALL AMOUNTS EXCEEDING THESE VALUES...BUT THIS DOES NOT APPEAR TO BE ENOUGH OF A WIDESPREAD THREAT TO JUSTIFY A FLOOD WATCH. CURRENT MOVEMENT OF CONVECTION IN SOUTHWEST LA AND FORECAST STORM MOTION FROM THE MODELS SUGGESTS CONVECTION WILL MOVE AROUND 10 KNOTS. MEAN STEERING CURRENTS ACROSS THE FORECAST AREA ARE FROM THE WEST AND NORTHWEST...SO THE MAIN AREA OF POSSIBLE ECHO TRAINING WOULD BE ALONG A STALLED SEA OR LAKE BREEZE BOUNDARY. THIS IS A VERY COMMON OCCURRENCE IN THE NEW ORLEANS METRO AREA. BECAUSE OF UNCERTAINTY...WILL DROP THE FLOOD WATCH BUT MAINTAIN WORDING OF LOCALLY HEAVY RAIN. LOCAL QPF AMOUNTS OF 1 TO 2 INCHES WITH VERY ISOLATED TOTALS IN THE 3 TO 5 INCH ARE EXPECTED WHICH MAY RESULT IN FLOODING OF STREETS AND SMALL STREAMS. WILL CUT BACK GRIDDED QPF AMOUNTS FOR MAP TO THE 0.5 TO 1 INCH RANGE. && .LIX WATCHES/WARNINGS/ADVISORIES... LA...NONE. MS...NONE. LA AND MS COASTAL WATERS...NONE. && 22
