Heavy rains have caused more road closures today. We will continue to update the map as information is received. Stay alert to changing conditions. Turn Around, Don’t Drown.
Thunderstorms could produce heavy rainfall across parts of the area late tonight into Wednesday morning which may lead to flash flooding. Be prepared to seek higher ground if you are in a flood prone area. Those camping near streams or coulee areas should be alert for rising water levels and possible flash flooding. Hot and humid conditions are expected Thursday into Friday when afternoon heat index values of 100 to 115 are possible. The worst conditions are expected Thursday afternoon.
Snow moving in this morning. Once the heavy snow starts, roads will quickly go from slippery to treacherous – in as little 1 to 2 hours. Snowfall rates of 1-2″ still expected, with totals of 8 to 12 inches in the main snow band. Several inches less for parts of northeast IA and southwest WI where warmer air will make a wintry mix more likely for the afternoon-early evening hours. Don’t travel later today if don’t absolutely have to. Road closures in some rural parts of IA likely tonight. Stay safe…even the groundhogs are.
Dangerous winter storm will rip across the region today, dropping 6 to 10 inches of snow for many. Strong winds will blow and drift the snow in open and unsheltered areas. Travel will go from slippery to hazardous to potentially impossible very quickly. Some road closures could occur later tonight. If traveling, exercise extreme caution and allow ample time to reach your destination. Delay or cancel some travel if necessary.
A winter storm will impact the region Monday and Monday night, bringing heavy snow and a wintry mix. An axis of 6 to 10 inches could fall from Iowa, across southern Minnesota and into northern Wisconsin. On the southeast side of the storm, a wintry mix with sleet, freezing rain and snow is more likely. Winter Storm Warnings will be in effect for Monday and Monday night. Prepare now for hazardous to dangerous travel conditions. High snowfall rates will quickly deteriorate road conditions. The evening commute will be impacted. Wind gusts upwards of 30 to 40 mph will add an additional hazard.
