   Mesoscale Discussion 0151
   NWS Storm Prediction Center Norman OK
   0425 PM CST Tue Feb 07 2017

   Areas affected...Portions of GA

   Concerning...Severe potential...Watch unlikely 

   Valid 072225Z - 080030Z

   Probability of Watch Issuance...20 percent

   SUMMARY...Convection spreading across portions of GA into the early
   evening hours could produce locally damaging wind gusts. Watch
   issuance is not anticipated.

   DISCUSSION...Loosely organized clusters of convection will continue
   spreading east-northeastward across portions of GA during the next
   few hours. While convective inflow should remain marginally
   unstable, with ample cloud coverage stunting surface heating and
   dewpoints only holding in the middle 50s, buoyancy/vertical shear
   will be sufficient for a risk for locally intense convection to
   continue spreading downstream. This activity would be enhanced by
   local storm-scale circulations/MCVs noted in recent radar data. With
   around 35 kt of flow in the 1-2-km above-ground layer per JGX VAD
   wind profile, convective momentum transport could support locally
   damaging wind gusts -- aided by sub-cloud evaporative
   cooling/downdraft enhancements in the only modestly moist
   environment. Weak instability, and veered flow ahead of the
   convection, will limit the overall severe risk.
