   Concerning...Severe Thunderstorm Watch 222...

   Valid 250121Z - 250315Z

   The severe weather threat for Severe Thunderstorm Watch 222
   continues.

   SUMMARY...Severe threat is expected to develop across the eastern
   Texas Hill Country and Texas Coastal Plains over the next few hours.
   Weather watch issuance will likely be needed.

   DISCUSSION...The latest satellite imagery shows a large MCS located
   across western and central Texas. The southern part of the MCS
   consists of a continuous line of strong to severe storms from the
   southern Texas Hill Country southward to the Rio Grand, along an
   axis of strong instability. The RAP is estimating MLCAPE along this
   corridor from 3500 to 4000 J/kg. The GRK WSR-88D VWP shows 40 kt of
   0-6 km shear with directional shear in the lowest 1 km AGL. This
   wind profile will support a severe threat with the more intense
   parts of the line. Wind damage and an isolated tornado threat will
   exist with rotating storms embedded in the line and with bowing line
   segments. Hail will also be likely the stronger cores. The line will
   move toward the edge of WW 222 over the next hour, necessitating
   watch issuance across the Texas Coastal Plains.
