URGENT - IMMEDIATE BROADCAST REQUESTED
Tornado Watch Number 45
NWS Storm Prediction Center Norman OK

The NWS Storm Prediction Center has issued a

* Tornado Watch for portions of 
  Arkansas
  Western and Northern Louisiana
  Far southeast Oklahoma
  East Texas

* Effective this Friday night and Saturday morning from 950 PM
  until 600 AM CDT.

* Primary threats include...
  A few tornadoes likely with a couple intense tornadoes possible
  Widespread damaging wind gusts to 70 mph likely
  Isolated very large hail events to 2 inches in diameter possible

SUMMARY...Multiple quasi-linear bands of storms will continue to
steadily progress east-northeastward across the region, with
line-embedded circulations and a few semi-discrete supercells ahead
of the convective bands. A moist environment and very strong
low-level shear will continue the tornado risk into the overnight
along with the potential for damaging wind gusts.

The tornado watch area is approximately along and 70 statute miles
east and west of a line from 35 miles north of Batesville AR to 40
miles south southeast of Lufkin TX. For a complete depiction of the
watch see the associated watch outline update (WOUS64 KWNS WOU5).

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.
