Weather Summary for Iowa
National Weather Service Des Moines IA
454 AM CDT Tue Oct 16 2018

Skies across the state were mostly clear overnight with just a few 
high clouds skirting across far northern Iowa. Early morning 
temperatures range from upper 20s to around 30 in southern Iowa to the
mid 30s in northern Iowa. Winds are generally light and out of the 
southwest across southern Iowa with gusty winds at 10 to 20 mph across
northern Iowa this morning. 

An area of low pressure situated to the north of the area will push
east today dragging another cold front through the state today. This
will bring gusty northwest winds and colder air into the state for
tonight into Wednesday. Some cloud cover is expected with the frontal
passage, but moisture is limited so no precipitation is expected.
Upper ridging that has been in place across the western US will begin
to build eastward into the central US late this week. This will allow
for a warming trend across the state for Thursday into Friday. However
another cold front will drop through the state late Friday bringing
cooler conditions back to Iowa for the weekend. Overall dry conditions
are expected through the week and into the weekend.
