Mesoscale Discussion 1038

   Areas affected...northwest OK into adjacent southwest KS

   Concerning...Severe potential...Watch unlikely 

   Valid 281513Z - 281645Z

   Probability of Watch Issuance...20 percent

   SUMMARY...Isolated hail to around 1.75 inches diameter is possible
   the next 1-2 hours across northwest Oklahoma into adjacent southwest
   Kansas.

   DISCUSSION...Elevated thunderstorms have developed this morning in
   an area of low-level east/southeasterly flow beneath upper northwest
   flow. Very steep midlevel lapse rates are supporting modest
   instability. VWP data from KVNX shows elongated hodographs above 2-3
   km amid deeper shear supporting transient supercells. This activity
   will be capable of producing severe hail to near 1.75 inches over
   the next 1-2 hours. With southward extent, overnight convection and
   outflow has modified the airmass into parts of southwest and central
   OK. The expectation is that this cluster of storms should gradually
   decrease in intensity with southeast extent over the next couple of
   hours. Trends will be monitored but watch issuance is not currently
   expected.
