   URGENT - IMMEDIATE BROADCAST REQUESTED
   Severe Thunderstorm Watch Number 40
   NWS Storm Prediction Center Norman OK
   225 AM CST Wed Mar 4 2020

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     Parts of the Texas Hill Country

   * Effective this Wednesday morning from 225 AM until 800 AM CST.

   * Primary threats include...
     Scattered damaging wind gusts to 70 mph possible
     Scattered large hail events to 1.5 inches in diameter possible
     A tornado or two possible

   SUMMARY...Thunderstorms along a cold front will likely persist for
   the next few hours, in advance of a strong upper storm system
   approaching from the Big Bend.  The storm environment favors a mix
   of supercell and linear structures, with the potential for a few
   embedded circulations and perhaps a tornado or two.  However, the
   main threats are expected to be large hail and damaging winds
   through the morning.

   The severe thunderstorm watch area is approximately along and 55
   statute miles east and west of a line from 70 miles east northeast
   of Junction TX to 40 miles east southeast of Del Rio TX. For a
   complete depiction of the watch see the associated watch outline
   update (WOUS64 KWNS WOU0).

   PRECAUTIONARY/PREPAREDNESS ACTIONS...

   REMEMBER...A Severe Thunderstorm Watch means conditions are
   favorable for 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. Severe thunderstorms can and occasionally do produce
   tornadoes.
