Winter Storm Overview
|
A winter storm brought moderate to heavy snow to much of eastern Iowa, northwest Illinois, and far northeast Missouri on February 16th, 2023. Snow began during the early morning across much of east central Iowa, with several locations (especially around Iowa City) seeing snow amounts around 4-6 inches around 6:00 AM. Light snow continued throughout the morning before the arrival of a stronger band of snow by early afternoon. This band impacted the Cedar Rapids / Iowa City metros during the early-mid afternoon before reaching the Mississippi River / Quad Cities metro by late afternoon and early evening, which lead to treacherous travel conditions for the evening commute. Snowfall totals ranged from around 2-6 inches in the Quad Cities / Dubuque metros, to around 7-12 inches in the Cedar Rapids / Iowa City metros. Lesser snow amounts were observed across southeast Iowa due to sleet mixing in with snow.
