Weather Summary for Iowa
National Weather Service Des Moines IA
259 AM CDT Thu Apr 25 2024

Today: 

High pressure has slid over the Great Lakes resulting in winds mainly
from the east or southeast across the state of Iowa this morning. 
While there were clear patches over eastern Iowa, clouds have spread 
over western and central Iowa. There may be a few sprinkles or a 
fleeting shower out there this morning, but the low level air is 
rather dry and any surface reports of rain has been scant. 
Temperatures range from around 40 degrees over far northeast Iowa to 
near 60 degrees over far southwest Iowa.

Sunshine will be limited today with northeastern portions of the state
having the highest chance of seeing some sunshine. Over southwest
Iowa, some showers may occur with many places elsewhere in the state 
remaining dry.

Tonight and beyond: 

Rain and storm chances increase later this evening into the morning
hours of Friday from southwest to northeast over Iowa. While there 
will likely be a break in the showers and storms Friday later in the 
morning to early afternoon, strong to severe thunderstorms are
forecast to develop later in the afternoon over portions of western
Iowa and then move northeast and east into the evening hours. Large
hail, a few tornadoes, and strong wind gusts will be possible with
this activity. Additional strong to severe storm chances along with
locally heavy rainfall are expected Saturday and then again Sunday 
over parts of the state. While it will not be stormy the entire
weekend, anyone with outdoor plans should have a way to receive 
weather warnings and know where nearby shelter is located in case
threatening weather nears your location.
