From the National Weather Service in the Quad Cities.

A BAND OF VERY LIGHT RAIN AND SPRINKLES WAS CONTINUING TO MOVE SLOWLY NORTHEASTWARD ACROSS AREAS FROM VINTON…TO NORTH OF CEDAR RAPIDS…ANAMOSA….AND OVER TOWARD BELLEVUE. SINCE TEMPERATURES WERE HOVERING AROUND THE FREEZING MARK IN THOSE AREAS…THIS LIGHT RAIN WAS FREEZING UPON MAINLY ELEVATED AND EXPOSED SURFACES. THIS LIGHT FREEZING RAIN MAY PRODUCE A LIGHT GLAZE ON UNTREATED SIDEWALKS AND BRIDGES WITH VERY LOCALIZED SLICK SPOTS DEVELOPING.
