Weather Summary for Iowa
National Weather Service Des Moines IA
334 AM CDT Mon Apr 22 2024

Today: 

A fairly quiet morning with generally warmer conditions compared to 
this time yesterday, as southwest winds remain over the region, with 
temperatures as of 3am in the 30s to low 40s. An area of high clouds 
can be seen on satellite streaming across central Iowa, with 
additional clouds further west beginning to make their way into the 
state.

Cloud cover will continue to increase through this morning as a 
system currently positioned over the Dakotas makes its way across 
Iowa later this morning, bringing the chance for occasional scattered 
rain showers today, along with some thunder at times. Temperatures 
will be on the warmer side today as southwest winds become quite 
gusty, with highs in the upper 60s to low 70s. A Wind Advisory is in 
effect from 11 am to 5 pm for sustained winds around 25 to 30 mph and
gusts upwards of 45 mph across much of Iowa.

Tonight and beyond: 

Scattered rain showers remain possible tonight and through at least
Tuesday afternoon. Lows are expected to fall into the 40s to low 50s,
which is much warmer than has been the case recently. Winds are also 
expected to decrease, shifting more westerly.

Outside of the aforementioned lingering rain chances Tuesday, winds
will increase across Iowa out of the northwest, with gusts upwards of
30 to 35 mph expected. Dry conditions return into Wednesday, with 
temperatures just a tad cooler in the upper 50s to mid 60s. A more wet
and active pattern continues to look likely by late work week and 
through the weekend, with periods of showers and thunderstorms, some 
which may be strong to severe on Friday into the weekend. Locally 
heavy rainfall with this activity is also looking possible. Details 
still remain unclear given this is several days ahead at this point, 
but close monitoring will continue. Temperatures are expected to warm 
back through the 70s into the weekend.
