8:30 PM Update - Snowfall has ceased over areas of western and central Iowa, with only the eastern third of the state still under a Snow Advisory as moderate to heavy snows may occur through midnight.

Across central Iowa, 2-5 inches of snow fell for a majority of the state with the heaviest surrounding the Des Moines area. A list of the Des Moines NWS reports can be found here. The areas of eastern Iowa aren't completely done with their snowfall, thus no final reports or images are available currently.

2:00 PM Update - Snowfall was light in Ames throughout the morning, however latest radar imagery and the view from outside indicate that moderate to heavy snowfall is occurring and going to continue through mid-afternoon over central Iowa. This band of snowfall is working out of eastern NE and western IA where report have nearly 5 inches of snow on the ground in Omaha and 2.5 inches in Sioux City. This snowfall may create some travel problems before the snow stops and crews can completely clear it, take extra precautions when driving.

Mainly an inch has fallen over central Iowa where the snows are finally beginning to fall heavier, eastern Iowa has yet to see more than light snow out of the system. You can view the latest winter weather radar image on my homepage see where the heavier snows are, represented by the brighter blue colors. White reflectivities in this instance indicate mainly light snow, keep in mind this is the Des Moines radar image currently and thus those of you who are in the corner of the state or extreme eastern Iowa may not see reflectivities over them as the radar cannot reach that far.
