   Mesoscale Discussion 0937
   NWS Storm Prediction Center Norman OK
   0137 PM CDT Fri Jun 02 2017

   Areas affected...Western/Central TX Panhandle

   Concerning...Severe potential...Watch unlikely 

   Valid 021837Z - 022100Z

   Probability of Watch Issuance...5 percent

   SUMMARY...A couple of landspouts possible through the afternoon.

   DISCUSSION...Visible satellite imagery shows a well-defined MCV near
   the central TX/NM border with building cumulus to the east of this
   feature across the western TX Panhandle. Weak flow aloft and
   resulting minimal shear will preclude organized thunderstorm
   activity and mostly weak multicellular is anticipated. Even so,
   vorticity-rich environment fostered by the presence of the MCV
   combined with the presence of steep low-level lapse rates (i.e.
   around 7.5 to 8 deg C per km from 0-3 km per the latest
   mesoanalysis) and low-level instability (evidenced by 0-3 km MLCAPE
   generally greater than 75 J/kg) will result in the potential for a
   few brief, non-mesocyclone tornadoes (i.e. landspouts) this
   afternoon. Brief and very marginal nature of the threat posed by any
   of these landspouts precludes the need for a watch.
