DES MOINES, Iowa -- The heaviest snowfall is out of the way in the metro, however, we still expect a rain-snow mix for the evening commute Tuesday.
Iowa State Patrol Sgt. Nathan Ludwig said between 6 a.m. and 2:30 p.m., there were 26 weather-related crashes and 44 calls for service in the metro, so use caution while traveling Tuesday and Wednesday.
A blizzard warning remains in effect Tuesday for areas north and west of the Des Moines metro. Winds will be strong from the north-northeast at 20 to 30 mph, gusts to 40 mph. This will create very difficult driving conditions all day through the start of Wednesday.
A winter storm warning has been canceled for Adair, Adams, Black Hawk, Cass, Grundy, Madison, Marshall and Polk counties. The warning is still in effect for Audubon, Boone, Bremer, Butler, Dallas, Guthrie, Hardin and Story counties until 6 a.m. Wednesday.
A strong area of low pressure is lifting into Iowa from the southwest. The storm is bringing blizzard conditions currently across Nebraska and Northwest Iowa. The snow tapered off in Des Moines by noon as drier air worked into the central and southern part of the state. There may even be a few rain showers at times during the afternoon and early evening. But the snow will still come down heavy to the northwest.
This afternoon looks drier from the Des Moines Metro to the southeast. A "dry slot" works it's way into the center of the storm pulling in that dry air. Northern Iowa will remain in the heavy snow band during that time. During the afternoon, there will be some light rain showers and drizzle from Des Moines to the southeast.
Another band of some wrap around moisture will move into central Iowa later this evening. It may start off as rain, but transition to snow and could give us another 1 to 2".
Totals will be in the 3 to 6" range through central Iowa, including Des Moines, with totals 8" + in Northwest Iowa. Southeast Iowa will see mainly rain. Blowing snow will continue to be a problem mainly in northwest Iowa through early Wednesday morning. It will be drier and calmer through the end of the week with daytime highs back in the 20s and 30s.
