Quick But Strong Push of Snow for Iowa Wednesday
A fast-moving clipper system will bring a short-lived but strong push of snow into Iowa on Wednesday, leaving the possibility of Des Moines receiving six or more inches of snow by Wednesday evening.
The low pressure center, which was bringing mostly light snow to the Dakotas and eastern Montana on Tuesday night, could leave up to 8 or 9 inches in localized areas, while the majority of central Iowa can expect a 4-7″ snowfall, mostly during the day on Wednesday.
The snow will move from northwest to southeast, meaning areas such as Sioux Falls, South Dakota and Sioux City, Iowa can expect accumulating snowfall before sunrise on Wednesday. Des Moines will see the snow start between 6 and 9 AM, and it will last all day before dissipating overnight Wednesday into Thursday. Kansas City and St. Louis can expect an inch or two of snowfall later Wednesday and into Thursday, and as the system moves south, it will quickly weaken and mostly dissipate by later Thursday in southern Missouri.
Winter Storm Warnings (see map) are up for most of Wednesday and last until 9pm CT for most parts of the Hawkeye State.
Behind the snow, temperatures will plummet, with highs in Des Moines on Thursday and Friday struggling to reach 10° both days. More snow is possible this weekend as a bigger system takes aim on the Midwest, including Iowa. Get those snow shovels ready, and as always, stay tuned to WeatherNationTV.com for the latest!
