Tornado Watch Number 249
NWS Storm Prediction Center Norman OK

east-southeastward through early tonight along a composite outflow
boundary sagging southward across east Texas. The potential for
supercells with large hail of 1-2 inches in diameter and a couple of
tornadoes will increase with new storm development south of the
outflow. Otherwise, embedded supercells and bowing segments will
pose a threat for damaging winds of 60-70 mph, as well as a couple
of tornadoes with embedded circulations.
The tornado watch area is approximately along and 55 statute miles
north and south of a line from 40 miles southwest of College Station
TX to 5 miles east southeast of Lafayette LA. For a complete
depiction of the watch see the associated watch outline update
(WOUS64 KWNS WOU9).
PRECAUTIONARY/PREPAREDNESS ACTIONS...
REMEMBER...A Tornado Watch means conditions are favorable for
tornadoes and severe thunderstorms in and close to the watch
area. Persons in these areas should be on the lookout for
threatening weather conditions and listen for later statements
and possible warnings.
