URGENT - IMMEDIATE BROADCAST REQUESTED

Tornado Watch Number 108

NWS Storm Prediction Center Norman OK

555 AM CDT Sun Apr 2 2017



The NWS Storm Prediction Center has issued a



* Tornado Watch for portions of

  Parts of central and east Texas



* Effective this Sunday morning and afternoon from 555 AM until

  100 PM CDT.



* Primary threats include...

  A few tornadoes likely

  Scattered damaging winds and isolated significant gusts to 75

    mph possible

  Scattered large hail and isolated very large hail events to 2.5

    inches in diameter possible



SUMMARY...A large cluster of thunderstorms that has persisted

overnight west of San Antonio will likely begin to organize into

more of a bowing line with time, with an attendant increase in the

damaging wind risk.  Embedded circulations will also pose a tornado

risk.  Ahead of the line of storms, more isolated cells now forming

in the Houston to Austin corridor will shift northward with time,

and some could become supercells capable of producing a few

tornadoes later this morning.  Large hail will also be possible with

the stronger storms.



The tornado watch area is approximately along and 65 statute miles

north and south of a line from 55 miles west of Hondo TX to 40 miles

south southeast of Tyler TX. For a complete depiction of the watch

see the associated watch outline update (WOUS64 KWNS WOU8).



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.
