REMAIN POSSIBLE THROUGH THE EARLY PARTS OF THE OVERNIGHT

MERGERS...WITH A SURFACE COLD POOL /5MB 2HR PRESSURE RISES AND A 15
DEG F TEMPERATURE DROP/ ALONG THE SOUTH EDGE OF THE DFW METROPLEX AS

ELEVATED/ AND THE EXISTING ORGANIZATION OF THE CONVECTIVE LINE WILL
REMAIN SUPPORTIVE OF SOME SEVERE-CALIBER WIND GUSTS...PARTICULARLY
ON THE SOUTHWEST PART OF THE MCS...WHERE SOME HAIL WILL ALSO REMAIN
