Weather Summary for Iowa
National Weather Service Des Moines IA
342 AM CDT Tue Apr 23 2024

Today: 

A trough of low pressure extended across Iowa overnight with 
southwest winds ahead of the boundary along with temperatures in the
50s. A few showers were also occurring ahead of the trough as it
gradually pushed southeast. Behind the boundary, winds were generally
west with readings in the 40s. 

Scattered showers are expected in far southern Iowa through daybreak 
with the rainfall ending by mid morning in the southeast. Otherwise, a
cold front slides into the state today with winds increasing from the
northwest. Temperatures are forecast to top out around 60 in the far 
north and near 70 in the south as the cooler air doesn't arrive until 
later in the day. 

Tonight and beyond: 

Cooler and dry conditions are expected tonight into Wednesday as
surface ridging slides across the Midwest. Overnight low are expected
to drop to near freezing in northeast Iowa with the possibility of
frost and freeze conditions late tonight. Otherwise, mostly sunny
skies are forecast on Wednesday with near normal temperatures.  

A more active weather pattern develops across the region later 
Thursday and into the weekend. A couple of different storm systems are
expected to produce widespread showers and storms Thursday night into
Friday evening and again from late Saturday into Sunday evening. It 
appears there may be a brief break in activity early Saturday between 
the systems. The threat for some severe storms exists, especially on 
Friday with heavy rainfall possible from both of the systems.
