The winter weather advisory continues for the counties in blue...the winter storm warning is still in effect until 6 am for the pink counties.
The snow is falling in the metro....sticking to the grassy areas...but leaving the roads just wet.
Slick roads are causing slow traffic west of Des Moines on Interstate 80...and south along I-35.
Highway 30 and 20 between Ames and Story City are also partially covered with slush and snow.
The rain/snow line is right on top of Des Moines. It is all rain in the southeastern 1/3 of the state. Waterloo just reported the rain changing to snow.
I am still looking for a rain to snow mix through midnight. The temperatures are staying right around 34 degrees. The dew point is 32 degrees. That means the temperature can't fall below the freezing point.
1 to 3 inches of wet snow is possible in Polk County. Heavier amounts will fall in the western portions of the county...lighter amounts in southeastern Polk.
There is still a good chance for 5 to 7 inches of snow in the Ames...Nevada...Marshalltown...Iowa Falls and Eldora areas of the state.
More updates tonight at 10 PM...blog updates through the overnight.
