Rain and isolated storms will continue through the overnight and into Sunday morning. During this time a cold front will push into NW Iowa changing rain over to snow, and potentially dropping 3-6” of snow Northwest of a Sioux City to Estherville line.
By noon on Sunday Central Iowa will see a mix of rain and snow, with minor accumulations of less than an inch in most cases likely.
