Tropical Storm Imelda Forms; Another Round of Heavy Rain and Potential Flooding in the Southwest

Another round of showers and storms with a heavy rain and flash flood threat will continue in the Southwest through Monday morning. Read More >

Overview

A strong area of low pressure moved across the Midwest on March 4th and 5th, producing a plethora of hazardous weather to the region. This low first brought soaking rainfall on March 4th, with numerous locations reporting between one to two inches of total rainfall. Frost depths by this time were down to zero inches, which helped the rain to soak into the ground.

March 5th saw a transition from the rain to more of a rain/snow mix or all snow, especially for areas west of the Mississippi River. We also saw very strong northwest winds across the area, with numerous locations reporting max wind gusts between 40 to 50+ mph. Although the snow was relatively light (less than 2 inches), the strong winds helped lead to blowing snow and reduced visibilities down to a quarter of a mile in Dubuque and Cedar Rapids. Additionally, the winds resulted in sporadic power outages over the area.

Highest Gusts
Cedar Rapids: 56 MPH
Moline: 52 MPH
Dubuque: 45 MPH
