The seasons first widespread significant snow event took place late on the 21st through the morning of the 22nd.  A compact upper level low pressure area lifted out of the southwest U.S. into northern Missouri.  A deformation area northwest of the low track produced a several hour period of heavy snowfall across southwest, south central, into central and parts of northeast Iowa.  At the height of the storm, snowfall rates were around one inch per hour.  The heaviest snowfall was over the southwest and south central counties.  Some of the heavier amounts include 9 inches reported at Blockton in Taylor County and at Lamoni in Decatur County, 8.5 inches at Osceola and Murray in Clarke County.  A swath of 8 inch snowfall extended across Wayne, Lucas, Monroe, and Mahaska Counties.  Winds of 15 to 25 mph accompanied the snow, resulting in drifting snow and patchy blowing snow.  Roads became snow packed and slippery with some road closures resulting from traffic accidents.
