An area of rain and snow will continue to slowly work north today through later tonight. Precipitation should begin to wrap up in northern Iowa around 9-11 PM tonight. That said, scattered flurries should linger from northwest to north central Iowa overnight into Thursday morning before the main activity arrives. Snow will increase across west into central Iowa by Thursday morning with the activity expanding into eastern Iowa by late morning and through the afternoon. A widespread snowfall event is likely during the day Thursday through late evening for most locations in the forecast area. Areas in extreme southern Iowa will have a mix of rain/snow which will limit accumulations. Snow will begin to taper off across west and central Iowa by late Thursday night and eastern Iowa by early Friday. Once Friday morning hits, a few snow showers may remain across northeast Iowa before the system works east of the state.
The storm system will have east/southeast winds on Thursday sustained 10-25 MPH with gusts 25-35 MPH for mainly the north and northeast half of the forecast area. The wind will switch around to the north/northwest by Friday sustained 5-18 MPH with the wind quickly subsiding later Friday morning. Gusty winds across central and eastern Iowa may lead to reduced visibility due to blowing of snow. Snowfall accumulations of 2-6" is expected across most of the forecast area with 4-8" off into portions of north central and northeast Iowa. Keep in mind, accumulations across southern Iowa will be on grass and elevated surfaces with limited pavement impacts. We are also watching for a clipper system by Saturday that may deliver additional light snow accumulations to the forecast area.
