CONCERNING...SEVERE THUNDERSTORM WATCH 152...

VALID 092237Z - 100000Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 152
CONTINUES.

MULTIPLE THUNDERSTORM UPDRAFTS ARE BEGINNING TO MERGE ACROSS THE ERN
TX PANHANDLE AND AN MCS SHOULD EVOLVE OVER THE NEXT FEW HOURS.
LATEST RADAR DATA SUGGESTS INDIVIDUAL STORM CELLS ARE MOVING SEWD AT
ROUGHLY 15KT BUT OVERALL SPEED MAY GRADUALLY INCREASE AS MCS MATURES
AND PRECIP OUTFLOW BECOMES MORE ORGANIZED. GIVEN THESE TRENDS IT
WOULD APPEAR LIKELY THAT A SLOW MOVING COMPLEX OF STORMS WILL SPREAD
ACROSS SWRN OK BETWEEN 00-03Z. LARGE HAIL CAN BE EXPECTED WITH THE
STRONGEST UPDRAFTS.
