Winter Storm Warning: Heavy Snow Likely

Iowa Watches and Warnings

After the smaller system that moved through the state late Saturday night, we are continuing to monitor a new system expected Monday night into early Tuesday morning. The National Weather Service has upgraded the winter storm watch to a winter storm warning. New model runs are showing the system tracking further to the southwest, causing a few counties on the southern end of the warning to be added. This winter storm warning is in effect for much of the northern and eastern portions of the state from 2 pm Monday afternoon through 3 am Tuesday morning. This is where models are consistently showing the highest accumulations. 6 to 8 inches of snow can be expected in the warning area, with the potential of higher amounts concentrated along and east of a line from Emmetsburg to Tama.
