Mesoscale Discussion 0034
   NWS Storm Prediction Center Norman OK

   Areas affected...northeast OK...southeast KS

   Concerning...Heavy snow 

   Valid 111421Z - 111615Z

   SUMMARY...A short duration (1-2 hours) of heavy snowfall rates
   around 1 inch per hour is expected this morning.

   DISCUSSION...Radar imagery during the 7-8am CST period has shown a
   blossoming of precipitation across north-central OK into southeast
   KS as mid-level ascent becomes maximized over this region.  Cushing,
   OK recently reported heavy snow as of 755am CST.  Forecast soundings
   in northeast OK show 700-500 mb lapse rates around 7 degrees C per
   km and weak upright instability (50-100 J/kg MUCAPE).  Therefore,
   weak convection resulting in bursts of heavy snow are seemingly
   likely during the next 2 hours as the precipitation shield gradually
   pivots east across northeast OK and southeast KS.
