Winter Weather Issues Through the Early Weekend

In All Posts, Winter Weather by Henry LukerLeave a Comment

Yet another round of moderate-to-heavy snow is expected late tonight over east central Iowa. Already, snow is beginning to form over northwest and west central Iowa. Light snow is being reported at the airports in Le Mars and Sioux City. Radar shows the heaviest band from Akron to Mapleton. This snow will continue to push towards west central and central Iowa by the mid-afternoon hours, reaching Fort Dodge and Ames by 2:00 p.m. and Waterloo, Cedar Rapids, Iowa City, and Davenport by 4:00 p.m. and 5:00 p.m. Points south of Interstate 80 will likely not see much of any accumulation concerns until the late evening to overnight hours, with far southern Iowa after midnight.

Generally, four-to-six inches are expected over much of the northeast half of the state. The heaviest totals will setup somewhere in a narrow band from Dubuque to Fort Dodge to Davenport. It’s important to note that we do not have 100% confidence in this area, and it may move northward or southward. We will be watching trends through the evening and make updates if needed. Locally higher amounts as much as ten inches may fall in some areas. But again, where these heaviest totals will fall, is still a bit unclear. To the southwest, snow totals quickly fall off, with far southwest Iowa only seeing a dusting. The Des Moines area will see two-to-four inches late tonight.

Our primary concern today is the afternoon and evening commute along Interstate 380 from Waterloo to Iowa City. Snow will begin falling during this time which will begin to cover roads and reduce visibilities. Please take it slow as you head home from work today in these areas. We may continue to see impacts during the commute Friday morning as well. A Winter Storm Warning goes into effect at 6:00 p.m. this evening over east central Iowa, remaining until 6:00 p.m. Friday. This is where the highest probability exists for higher snowfall totals. Elsewhere, a Winter Weather Advisory also goes into effect at various times this evening, remaining until various times on Friday. For specific information for your local area, please see our Active Alerts page.

Blowing and drifting will be a bit of a concern with sustained winds from the northwest at 10-15 MPH, gusting to 25 MPH at times. This will be more of an issue late tonight and into tomorrow morning. Another few inches may fall across areas south of Interstate 80 on Saturday. Two-to-four inches is possible there, highest closer to the Missouri border.
