   AREAS AFFECTED...SWRN KS
   
   CONCERNING...HEAVY SNOW 
   
   VALID 080710Z - 081115Z
   
   A NARROW WEDGE OF MODERATE TO HEAVY SNOW IS EXPECTED TO DEVELOP
   ACROSS PORTIONS OF SWRN KS OVER THE NEXT FEW HOURS.  SNOW RATES MAY
   APPROACH ONE INCH PER HOUR.
   
   EARLY MORNING SATELLITE IMAGERY DEPICTS A FAIRLY WELL DEFINED UPPER
   VORT OVER THE WRN OK/NWRN TX PANHANDLE REGION.  THIS FEATURE IS
   SHEARING EWD INTO AN AREA OF HIGHER RH WHERE ASCENT SHOULD EASILY
   INDUCE A STRENGTHENING BAND OF HEAVY SNOW...SOME OF IT CONVECTIVE IN
   NATURE.  ALTHOUGH A BIT OF FREEZING RAIN HAS BEEN REPORTED AT TIMES
   NEAR THE SFC FREEZING LINE IT APPEARS MOST OF THE HEAVIER
   PRECIPITATION NORTH OF THE UPPER VORT WILL FALL AS SNOW ACROSS SWRN
   KS.  LATEST FORECAST RUC SOUNDINGS ALSO SUGGEST SUFFICIENT ELEVATED
   INSTABILITY FOR UPRIGHT CONVECTION IF LIFTING PARCELS IN THE
   650-700MB LAYER.  HEAVIER SNOW BURSTS ARE POSSIBLE IF THUNDERSTORMS
   DEVELOP ACROSS THIS REGION.
