THE SEVERE WEATHER THREAT FOR TORNADO WATCH 225 CONTINUES.

NRN SEGMENT OF LINEAR MCS HAS BEEN WEAKENING OVER THE PAST FEW HOURS
OVER MS AS CONVECTION OUTRUNS STRONGER SURFACE-BASED INSTABILITY.
THE TRAILING PORTION OF THE LINE...ACROSS SERN LA...REMAINS STRONG
BUT POORLY ORGANIZED. STRONG LOW LEVEL CONVERGENCE AND VERY MOIST
AIR MASS REMAIN ACROSS MUCH OF SRN LA AND CONDITIONS ACROSS THESE
AREAS MAY REMAIN SUPPORTIVE OF ISOLATED SEVERE WEATHER THROUGH EARLY

APPEAR IMMINENT.
