URGENT - IMMEDIATE BROADCAST REQUESTED

Tornado Watch Number 445

NWS Storm Prediction Center Norman OK

930 PM CST Wed Dec 26 2018



The NWS Storm Prediction Center has issued a



* Tornado Watch for portions of

  East-Central Texas



* Effective this Wednesday night and Thursday morning from 930 PM

  until 400 AM CST.



* Primary threats include...

  A couple tornadoes possible

  Scattered damaging wind gusts to 70 mph possible



SUMMARY...As some additional warming and moistening occurs, isolated

storms could intensify late this evening/overnight ahead of an

eastward-moving convective line and cold front. While a particularly

widespread severe risk is not expected, adequate

moisture/instability exists in the presence of very strong

deep-layer/low-level shear for the possibility of damaging winds and

a tornado risk.



The tornado watch area is approximately along and 65 statute miles

east and west of a line from 25 miles north northeast of Tyler TX to

20 miles south southeast of College Station TX. For a complete

depiction of the watch see the associated watch outline update

(WOUS64 KWNS WOU5).



PRECAUTIONARY/PREPAREDNESS ACTIONS...
