   NWS Storm Prediction Center Norman OK
   0550 PM CDT Fri May 19 2017

   Areas affected...portions of central Texas

   Concerning...Tornado Watch 246...

   Valid 192250Z - 200045Z

   The severe weather threat for Tornado Watch 246 continues.

   SUMMARY...Severe/isolated tornado risk continues.

   DISCUSSION...Latest radar loop shows several vigorous/rotating
   storms across parts of the watch area, primarily within two small
   clusters -- one between SJT and ABI, and the second northwest of
   ABI.  With these storms ongoing within a moist/moderately unstable
   airmass, expect the risk to continue over the next several hours.

   One negative, with respect to tornado risk, is weakening low-level
   flow with southwestward extent across the watch area.  Still, risk
   for a tornado or two persists -- especially over northern portions
   of the watch, along with risk for large hail and locally damaging
   downdrafts.
