SUMMARY...A well-organized band of thunderstorms will cross the

watch area through the remainder of the morning.  Although the storm

mode has become mostly quasi-linear, and the bulk of severe events

should be thunderstorm wind, strong low-level shear in the inflow

region indicates some embedded circulations still will have tornado

potential.



The tornado watch area is approximately along and 80 statute miles

east and west of a line from 45 miles southeast of Waco TX to 35

miles north of El Dorado AR. For a complete depiction of the watch

see the associated watch outline update (WOUS64 KWNS WOU0).



PRECAUTIONARY/PREPAREDNESS ACTIONS...



REMEMBER...A Tornado Watch means conditions are favorable for

tornadoes and severe thunderstorms in and close to the watch

threatening weather conditions and listen for later statements

and possible warnings.
