increase in storm coverage/intensity into this evening.  More
isolated supercells with very large hail will be possible initially
across western Oklahoma and northwest Texas.  Storms will then grow
upscale into a more solid squall line by late evening, when damaging
winds will become the more common threat.  A tornado or two could
occur with the initial discrete supercells, as well as later this
evening with circulations embedded in the developing line across
central Oklahoma.

The tornado watch area is approximately along and 60 statute miles
east and west of a line from 45 miles west northwest of Ponca City
OK to 55 miles southwest of Wichita Falls TX. For a complete
depiction of the watch see the associated watch outline update
(WOUS64 KWNS WOU3).

PRECAUTIONARY/PREPAREDNESS ACTIONS...
