An ICE STORM WARNING is in effect for Grundy and Tama counties tonight through Monday evening. A WINTER WEATHER ADVISORY for wintry mix and ice is in effect Sunday evening through Monday night for all of eastern Iowa.
Tonight: This evening will be mostly cloudy across all of eastern Iowa, ahead of our wintry weather. Around 4PM and after, snow, sleet, and/or freezing rain will be possible south of I-80. Around 10 PM, scattered wintry mix and freezing rain will track north to near HWY 20 (Waterloo to Dubuque). This may be preceded by freezing drizzle. After midnight, widespread wintry mix and freezing rain is expected across eastern Iowa. Temperatures will be in the 20s overnight, with a SE wind 5-10 mph.
Monday: Freezing rain is likely during the morning hours, making the morning commute very tricky. Expect 0.10″ to 0.25″ of ice when all is said and done, with the highest amounts in western portions of the viewing area. A few spots could get 0.30″ of ice. Between 9AM and Noon, temperatures will begin to warm above freezing, transitioning everything over to rain from south to north. The rain continues into the evening hours. A half inch to inch of rain is possible across eastern Iowa. Highs reach the middle and upper 30s with an east wind 5-10 mph. While isolated power outages and tree damage is possible, it is not expected to be widespread.
Monday Night: Rain becomes more scattered, and as temperatures slowly drop, there could be a little snow and sleet mixing in at times. Lows will be in the 20s with a north wind 5-10 mph.
Tuesday: Scattered wintry mix possible in the morning hours, so watch for slick spots. The afternoon will be cloudy with highs in the middle 30s and a NW wind 5-10 mph.
