AREAS AFFECTED...SOUTHERN MS/NORTHERN AND CENTRAL LA

CONCERNING...SEVERE THUNDERSTORM WATCH 618...

VALID 192041Z - 192245Z

SEVERE THUNDERSTORM WATCH 618 CONTINUES UNTIL 01Z ACROSS
CENTRAL/SOUTHERN MS INTO NORTHEAST LA...WITH CONTINUED POTENTIAL FOR
DAMAGING WINDS/LARGE HAIL. WILL MONITOR FOR THE POTENTIAL OF AN
ADDITIONAL SEVERE THUNDERSTORM WATCH ISSUANCE ACROSS THE REMAINDER
OF NORTHERN/CENTRAL LA.

NUMEROUS STRONG/SEVERE STORMS ARE ONGOING ACROSS SOUTH CENTRAL
MS...GENERALLY ALONG/SOUTH OF THE I-20 CORRIDOR. OUTSIDE OF
CONVECTIVE OUTFLOWS...AMBIENT AIRMASS REMAINS VERY UNSTABLE...WITH
MLCAPES IN EXCESS OF 3000 J/KG. A SUFFICIENT COLD POOL APPEARS TO
HAVE ORGANIZED ACROSS SOUTH CENTRAL MS...WHICH IS LIKELY ENHANCING
THE WESTWARD PUSH OF A ROUGHLY NORTH-SOUTH ORIENTED BAND OF
STRONG/SEVERE STORMS FROM NEAR VICKSBURG TO NATCHEZ AS OF 2040Z.
FORWARD PROPAGATION INTO A VERY UNSTABLE AIRMASS AND 15-20 KTS OF
STORM RELATIVE LOW LEVEL INFLOW WILL LIKELY SUPPORT A DAMAGING
WIND/LARGE HAIL THREAT INTO MUCH OF NORTHERN/CENTRAL LA. IF IT
APPEARS AN ORGANIZED THREAT WILL REACH OUT OF WW 618 WITH WEST
EXTENT...AN ADDITIONAL WATCH COULD BE NEEDED.
