   MESOSCALE DISCUSSION 0065
   NWS STORM PREDICTION CENTER NORMAN OK
   1138 AM CST TUE FEB 04 2014

   AREAS AFFECTED...ERN KS...MUCH OF MO...FAR SERN NEB AND SRN
   IA...SRN/CNTRL IL

   CONCERNING...HEAVY SNOW 

   VALID 041738Z - 042345Z

   SUMMARY...HEAVY SNOW WILL PERSIST ACROSS ERN KS AND MO...AND
   CONTINUE EXPANDING NWD/EWD INTO PORTIONS OF SERN NEB/SRN IA AND
   CNTRL/SRN IL. RATES NEAR 1 INCH PER HR ARE EXPECTED...BUT COULD BE
   LOCALLY HIGHER WITHIN MORE CONCENTRATED BANDS.

   DISCUSSION...RADAR IMAGERY SHOWS WIDESPREAD LIGHT TO MODERATE SNOW
   FALLING FROM CNTRL KS INTO SRN IL. HEAVIER RATES ARE LIKELY
   OCCURRING WITHIN A MORE CONCENTRATED BAND FROM NEAR ICT TO OJC /AS
   OF 1730Z/. ASSOCIATED CYCLONE IS LOCATED OVER OK...AND WILL CONTINUE
   TO SLOWLY ACCELERATE TOWARDS THE MID-MS VALLEY THROUGH THIS EVENING.
   A PRONOUNCED DRY SLOT WAS MOVING INTO SRN KS AS WELL...WHICH SHOULD
   LEAD TO A DECREASE/SLIGHT NWD SHIFT OF SNOWFALL ACROSS SRN PORTIONS
   OF CNTRL/ERN KS.

   WITH QUASI-CLOSED NATURE OF THE SYSTEM IN THE LOW-LEVELS...AT LEAST
   WEAK CONVERGENCE IN THE 700-800 MB LAYER /AS OBSERVED IN REGIONAL
   VWP DATA/ SHOULD CONTINUE TO MAINTAIN BANDED STRUCTURES ON THE NRN
   PERIPHERY OF THE CYCLONE /I.E. ACROSS NERN KS...NRN MO INTO FAR SERN
   NEB AND SRN IA/. MEANWHILE...ADDITIONAL AREAS OF MODERATE TO LOCALLY
   HEAVY SNOWFALL MAY OCCUR WITHIN THE WARM CONVEYOR REGION...PRIMARILY
   ACROSS ERN MO AND SRN/CNTRL IL. THERMODYNAMIC PROFILES WILL REMAIN
   FAVORABLE FOR ENHANCED SNOWFALL RATES...WITH THE PRESENCE OF A DEEP
   ISOTHERMAL LAYER BENEATH THE DENDRITIC GROWTH LAYER...AS NOTED IN
   MORNING SOUNDINGS.
