   Concerning...Severe Thunderstorm Watch 250...

   Valid 300116Z - 300315Z

   The severe weather threat for Severe Thunderstorm Watch 250
   continues.

   SUMMARY...The potential for isolated occurrences of large hail
   and/or severe wind gusts will persist for the next couple of hours.

   DISCUSSION...As of 01:10 UTC, a series of small storms were located
   from southern Noble into Garfield and Grant Counties, to the north
   of an outflow boundary. It's unclear whether that convection is
   truly surface-based or slightly elevated. In either case, ample
   instability (see 00 UTC OUN sounding) persists within the inflow air
   mass. Both the KTLX and KVNX VWPs indicate a gradual increase in
   wind speed in the lowest 1.0-1.5 km AGL, a trend which is expected
   to continue through mid to late evening. A resultant increase in
   storm-relative inflow may support storm intensification with
   attendant risk for large hail and perhaps locally severe wind gusts
   for the next couple of hours.

   The current expectation is that the remaining valid portion of the
   watch will be allowed to expire at 03 UTC.
