Weather Summary for Iowa
National Weather Service Des Moines IA
1255 AM CDT Fri Apr 26 2024

Today: 

Clouds had spread over the state early this morning and winds from 
the southeast were averaging 10 to 20 mph with gusts to near 30 mph in
some places. Over western Iowa, showers and storms were just crossing
the Missouri River into western Iowa after midnight this morning. 
Temperatures in most locations were in the 50s.

The showers and embedded thunderstorms will move into central Iowa by
sunrise today and spread across eastern Iowa this morning. As this 
wave of precipitation moves out later this morning and afternoon, 
clouds will remain over northern into central Iowa with some breaks of
sunshine over southern Iowa, particularly southwest. Strong to severe
storms are expected to develop near the Missouri River late this 
afternoon and push into western and central Iowa this evening and 
eastern Iowa late evening and after midnight. Large hail, a few 
tornadoes, and strong wind gusts will be possible with this activity. 

In addition to the stormy weather, it will be breezy with wind speeds
averaging 15 to 25 mph and gusts of 25 to 35 mph much of the time 
today and through this weekend as well.

Tonight and beyond: 

There should be a break in widespread activity after the storms exit
tonight until later Saturday afternoon when strong to severe storms 
are once again expected. In addition, storms moving over the same area
with little break between rounds may result in ponding in low lying 
and poor drainage areas and perhaps localized flooding as storms
continue into Saturday night. There may be some lingering showers or 
storms on Sunday, but another round of strong to severe storms will 
be possible later in the day into the evening. Anyone with outdoor 
plans should have ways to receive weather warnings and know where 
nearby shelter is located in case threatening weather nears their 
location.
