   Mesoscale Discussion 0670
   NWS Storm Prediction Center Norman OK
   0354 PM CDT Fri May 22 2020

   Areas affected...Southeast Nebraska and Northeast Kansas

   Concerning...Severe potential...Watch unlikely 

   Valid 222054Z - 222230Z

   Probability of Watch Issuance...5 percent

   SUMMARY...A brief tornado is possible this afternoon/evening in
   southeast Nebraska and northeast Kansas.

   DISCUSSION...Several bands of shallow convection have developed in
   the proximity of the upper low/surface MCV in northern Kansas.
   Low-level streamwise vorticity is enhanced in this region with 0-1
   SRH around 100 to 150 m2/s2. Low-level flow is mostly veered where
   instability has increased to the east of the circulation. However,
   there may be some brief overlap between the better instability and
   favorable wind profile. The limited moisture/instability will likely
   be the limiting factor to a greater threat.
