Weather Summary for Iowa
National Weather Service Des Moines IA
346 AM CST Tue Dec 31 2024

Today: 

Low pressure moving from Missouri into Central Illinois overnight
produced a broad area of light rain and snow across central and
southern Iowa early this morning. There were spotty areas of snow
accumulations with a few areas receiving around an inch or so.
Most primary roads and highways remained wet although less traveled
roads did become slushy in areas. Otherwise, northwest winds increased
and were common from 10 to 20 mph with gusts to almost 30 mph at 
times. 

The light precipitation is expected to come to an end this morning as
the system pulls away from the state. Some minor snow accumulations,
generally less than an inch remain possible in far south central to
southeast Iowa through mid morning, otherwise the north winds persist
for much of the day as cooler air arrives. Additional flurries are
expected late this afternoon into the evening as another weak system
passes through the state. 

Tonight and beyond: 

Any flurries are forecast to end tonight with clearing expected toward
daybreak on New Years Day. Mostly sunny skies will greet the New Year
with near normal temperatures in the mid 20s to lower 30s. However,
a clipper system approaches the state on Thursday with light snow
overspreading much of central into southern Iowa. Minor accumulations
are forecast by Thursday evening along with the arrival of cooler air.
Highs by Friday are forecast to remain in the teens to lower 20s over
much of the state as cold polar air overspread the Midwest.
