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.
