745 PM CST SAT MAR 13 1999

WELL...UPPER AIR RUN SHOWING STRONG H8 WAA AND LLVL JET OF 40 KTS.
HOWEVER...SURFACE FLOW STILL E-NE AND WHICH IS OFFSETTING ANY
CLIMBING TEMPS FOR THE MOMENT.  MAIN PRECIP AXIS IS ACROSS SE TIER
OF COUNTIES FROM STRONG DYNAMICS OVER AL.  HOWEVER...THE INTENSITY
IS WEAKER THAN EXPECTED DUE TO STRONG CONVECTION ACROSS MS/AL.

NO UPDATES AT THE MOMENT...AS THE MAIN CONCERN IS STILL OVER THE 1000-
2500 FT PLATEAU. THEY ARE STILL 36/33 AT CSV AND EVENING SOUNDING
WET BULB PLOT COULD SUPPORT SN/PL WITH THE PREDOMINATE RAIN.
SLIDELL ASKED FOR A NEW QPF AND HAVE LOWERED QPS BASES ON NEW RUC AND
OLD AVN.  LOOKS LIKE BEST AREA WILL BE SE COUNTIES TONIGHT AND NW
COUNTIES SUN AFTERNOON.

WATER VAPOR LOOP HAS UPPER LOW SLIGHTLY FARTHER S THAN EARLIER PROGGED.
LAST THOUGHT IS THAT CLOSELY WATCH THE DRY SLOT OVER AR...WHICH COULD
THROW A WRENCH INTO THIS FORECAST.
