   Areas affected...western OK

   Concerning...Severe potential...Watch unlikely 

   Valid 301153Z - 301400Z

   Probability of Watch Issuance...5 percent

   SUMMARY...Sporadic strong wind gusts and isolated hail near 1 inch
   are possible for a few hours this morning. A watch is not expected
   at this time.

   DISCUSSION...Scattered elevated thunderstorms are ongoing across
   western OK this morning. This convection is developing in a warm
   advection regime as a shortwave impulse tracks eastward across KS. A
   30 kt southwesterly low level jet is aiding in semi-organized
   clusters on the edge of steep midlevel lapse rates across the
   southern and central High Plains. Most recently, a 59 mph gust was
   observed by the Oklahoma Mesonet site at Weatherford. Other gusts in
   the region have been sub-severe over the last hour. In addition to
   gusty winds, isolated hail near 1 inch is possible with the
   strongest cells. As the low level jet weakens through the morning
   and the upper shortwave impulse shifts east into MO, isolated severe
   potential should decrease as well across western OK.
