The models continue show the potential for a major winter storm in the state by Friday morning. The storm track and precipitation changeover timing is still yet to be determined, as this system still remains a few days away.
The low will develop over the Rockies and will move east, and as it does it will strengthen over Iowa during the day Friday. Precipitation will start out initially as rain very late Thursday evening, but will quickly transition over to snow by early Friday morning. Due to the strengthening low, heavy snow appears likely from east of I-29 to west of I-35 and north of I-80 to south of I-90.
Across central and southeast Iowa, rain will transition over to snow later in the morning Friday, which will limit snowfall accumulations. There will be even a period of time Friday morning that thunderstorms will be possible across southeast Iowa.
Besides the heavy snowfall across the northwest half of the the state, very strong winds will be a concern. Winds will be sustained at 20 to 30-mph with gusts over 40-mph, which will lead to reduced visibilities. This storm system will need to be watched closely in the following days as it looks to have significant impacts on Friday.
