WINTER STORM WARNING: Part 1

A potent winter storm is set to impact central Iowa late tonight through Monday morning. A mixture of snow and freezing rain is forecast to develop over southern Iowa late Sunday night into early Monday morning. The precipitation will spread north during the morning hours Monday. The greatest threat for freezing rain will be across southeast Iowa, while the greatest threat for heavy snow will be over western and northern Iowa, and a wintry mix  into central Iowa.

A winter storm warning will be in effect from 3am Monday to midnight Monday night. Precipitation is expected to lift into far southern Iowa late tonight, then spread northward Monday morning. A mixture of freezing rain and sleet is expected east of interstate 35, with mainly snow west, though a period of a wintry mix is possible. The precipitation will switch to all snow by mid afternoon.

Iowa Snowfall forecast

Total snow amounts will vary from 6 to 9 inches over western Iowa to 1 to 4 inches far southeast. Total ice amounts of three to four tenths of an inch with locally higher amounts are possible over the southeast with less than one tenth inch elsewhere.

Winds will increase out of the east to northeast Monday morning and reach sustained speeds of 25 to 30-mph, with gusts over 40-mph. Blowing snow conditions are likely and may reduce visibility down to one quarter mile at times.

Hazardous travel conditions are anticipated Monday. Ice buildup in the south combined with the strong winds may lead to downed power lines and tree branches, potentially causing power outages.

A winter storm warning means significant amounts of snow, sleet, and ice are expected or occurring. Strong winds are also possible. This will make travel very hazardous or impossible.

More winter storm warnings will be issued this afternoon so check back for the latest updates.
