NWS New Orleans, LA wrote its last area forecast discussion before the first event at Jul 7, 1:30 AM CST, 11 hours 57 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NEW ORLEANS/BATON ROUGE LA 230 AM CDT WED JUL 7 2004 .DISCUSSION... LOOKING AT 00Z MODEL RUNS...ALL STATISTICAL PRODUCTS HAVE LOWERED POPS 20% ON AVERAGE FROM 12Z TO 00Z YESTERDAY. THE DRYING TREND STARTED AT 18Z YESTERDAY AND CONTINUED THROUGH 00Z YESTERDAY EVENING. THIS IS WHERE THE QUESTIONS ARRISE. AFTER SPEAKING WITH LCH...THEY NOTICED THE DOWNWARD TREND IN THE 18Z MOS RUN WHICH STILL USED THE 12Z SOUNDING DATA. THE LCH SOUNDING TAKEN AT 00Z WAS WAY TOO DRY. SINCE THE MOS PRODUCTS SHOW A DECREASING TREND BEFORE THE 00Z RELEASE...THERE MAY BE SOME VALIDITY TO THE DECREASE. FINAL THOUGHTS IS THAT THE DRY SOUNDING WAS INVOLVED IN SOME WAY OF BRINGING POP NUMBERS DOWN ON THE 00Z MOS RUN. BUT SINCE I AM NOT SURE HOW MUCH...WILL ONLY DROP POP NUMBERS BY 10% ACROSS THE BOARD. THIS SEEMS TO MATCH VERY WELL WITH LCH AND MOB AS WELL. WILL NOT MAKE ANY CHANGES WHATSOEVER TO ANY OTHER PORTION OF ONGOING PACKAGE. AFTER MAKING A CALL TO NCEP...THEY WILL BE RUNNING THE 06Z CYCLE MODELS WITHOUT THE 00Z LCH SOUNDING DATA TO SEE IF THERE IS ANY DIFFERENCE. THANKS LCH FOR COORD... && PRELIMINARY POINT NUMBERS...
