   NWS STORM PREDICTION CENTER NORMAN OK
   0729 AM CDT SUN MAR 24 2013
   
   AREAS AFFECTED...FAR E-CNTRL KS...CNTRL MO...FAR W-CNTRL IL
   
   CONCERNING...HEAVY SNOW 
   
   VALID 241229Z - 241630Z
   
   SUMMARY...BAND OF MODERATE TO HEAVY SNOWFALL WILL CONTINUE MOVING
   EWD ACROSS CNTRL MO AS THE UPPER LOW PROGRESSES EWD. SOME
   INTENSIFICATION OF THIS BAND IS POSSIBLE WITH SNOWFALL RATES LOCALLY
   EXCEEDING 1 INCH PER HOUR.
   
   DISCUSSION...RECENT RADAR IMAGERY AND SURFACE OBSERVATIONS DEPICT A
   BAND OF MODERATE TO HEAVY SNOW ACROSS CNTRL MO /ALONG A LINE FROM
   MKC TO DMO TO COU/. MOST OBSERVATIONS ARE CURRENTLY REPORTING
   MODERATE SNOW AND 1/2 MILE VISIBILITIES WITH THE EXCEPTION OF IXD IN
   FAR W-CNTRL KS WHICH IS REPORTING HEAVY SNOW. LIGHTNING HAS ALSO
   BEEN OBSERVED OVER E-CNTRL MO /AROUND COU/.
   
   RECENT RADAR IMAGERY SHOWS REFLECTIVITY ORIENTED ROUGHLY N-S FROM
   CNTRL MO SWD INTO NERN AR WITH SOME EMBEDDED CONVECTIVE ELEMENTS.
   RECENT WV SATELLITE IMAGERY HAS ALSO SHOWN A COOLING TREND IN CLOUD
   TOP ROUGHLY ALONG THE SAME AREA. THIS MAY BE THE DEVELOPMENT OF A
   MORE MOIST WARM CONVEYOR...WHICH WOULD THEN SUPPORT AN INCREASE IN
   SNOWFALL RATES ACROSS CNTRL MO AND FAR W-CNTRL IL.
   ADDITIONALLY...12Z SGF SOUNDING SHOWS A WEAKLY UNSTABLE LAYER
   BETWEEN 700-500 MB...WHICH IS WITHIN THE FAVORED DENDRITIC GROWTH
   ZONE.  AS SUCH...SOME INTENSIFICATION OF THE CURRENT BAND IS
   POSSIBLE WITH SNOWFALL RATES LOCALLY EXCEEDING ONE INCH PER HOUR.
