   Areas affected...central Iowa   
      
   Concerning...Heavy snow=20   
      
   Valid 070054Z - 070400Z   
      
   SUMMARY...Moderate to heavy snow to continue across portions of   
   central Iowa over the next couple of hours. Occasional rates 1"/hr   
   with heavier bands.   
      
   DISCUSSION...Recent radar and surface observations suggest moderate   
   to heavy snow continues across portions of central Iowa. This is   
   occurring near the surface low and in the region of strong DPVA   
   aloft overspreading central Iowa. Two regions that will favor heavy   
   snow (possible 1"/hr rates) over the next couple of hours are near   
   the zone of 700-850 mb frontogenesis across central Iowa north of   
   Des Moines and in a smaller mesoscale sector along and south of I-80   
   and trending eastward of I-35 where a more narrow band of heavy snow   
   has developed.  Guidance indicates a gradual downward trend in   
   snowfall rates is expected through the late evening/early morning   
   Sunday. However, periods of locally moderate snow may continue at   
   times across northeastern Iowa into southern Wisconsin/northern   
   Illinois.
