   MESOSCALE DISCUSSION 0006
   NWS STORM PREDICTION CENTER NORMAN OK
   0249 PM CST SUN JAN 05 2014

   AREAS AFFECTED...SCNTRL THROUGH ECNTRL IL...CNTRL AND NRN IND...NWRN
   OH AND SRN LOWER MI

   CONCERNING...HEAVY SNOW 

   VALID 052049Z - 060045Z

   SUMMARY...BANDS OF MODERATE TO HEAVY SNOW WILL DEVELOP NEWD THROUGH
   SCNTRL AND ECNTRL IL...CNTRL AND NRN IND...NWRN OH AND SRN LOWER MI
   INTO EARLY EVENING. SNOWFALL RATES MAY LOCALLY EXCEED 1 INCH PER
   HOUR WITHIN THE HEAVIER SNOW BANDS.

   DISCUSSION...THIS AFTERNOON BANDS OF MODERATE TO HEAVY SNOW PERSIST
   FROM SRN AND ECNTRL IL NEWD THROUGH NRN IND AND SRN LOWER MI. IT
   APPEARS THAT SOME DRYER AIR HAS BEEN ENTRAINED INTO CNTRL IND
   BETWEEN THE WARM ADVECTION RAIN BAND AND THE ZONE OF HEAVIER SNOW TO
   THE WEST WHICH IS RESULTING IN A TEMPORARY REDUCTION IN SNOWFALL
   RATES ACROSS CNTRL IND. HOWEVER...AGEOSTROPHIC FORCING WITHIN EXIT
   REGION OF AN UPPER JET ROTATING THROUGH BASE OF SYNOPTIC TROUGH WILL
   SUPPORT DEEPENING OF SFC LOW AS IT DEVELOPS NEWD THROUGH IND AND OH
   ALONG A QUASI-STATIONRY FRONT WHERE SURFACE OBSERVATIONS CURRENTLY
   SHOW THE STRONGEST PRESSURE FALLS. FRONTOGENETIC FORCING AND DEEP
   ASCENT SHOULD REMAIN AUGMENTED ALONG BAROCLINIC ZONE NORTH AND WEST
   OF THE MIGRATORY LOW AND CONTINUE TO PROMOTE NEWD DEVELOPMENT OF
   MODERATE TO HEAVY SNOW BANDS INTO THE EARLY EVENING.
