   Areas affected...Central and East Texas

   Concerning...Tornado Watch 286...

   Valid 222308Z - 230115Z

   The severe weather threat for Tornado Watch 286 continues.

   SUMMARY...A threat for tornadoes, wind damage and isolated large
   hail will continue for a few more hours across parts of central and
   east Texas. As the severe threat moves toward the eastern edge of WW
   286, a local extension or new watch may be needed.

   DISCUSSION...The latest hi-resolution radar imagery from Fort Worth
   shows a small cluster of intense storms in the northern Texas Hill
   Country, in Lampasas, Coryell, and McLennan counties. Multiple
   supercells are ongoing, and one of the storms has had a persistent
   circulation. This cluster of storms will continue to move eastward
   into a corridor of extreme instability, where MLCAPE is estimated by
   the RAP in the 4500 to 5500 J/kg range. The nearest WSR-88D VWP,
   located at Granger, TX has 0-6 km shear of 45 to 50 knots, and 0-3
   km storm-relative helicity fluctuating in the 200 to 300 m2/s2 range
   over the last half hour. This environment should be favorable for
   supercells with a tornado threat. A strong tornado will be possible.
   Supercells will also be capable of isolated large hail. Hailstones
   of greater than 2 inches in diameter may accompany the most intense
   updrafts. Also, radar suggests that damaging winds will be likely
   near the strongest downdrafts, and winds could exceed 70 knots
   locally.
