Weather Summary for Iowa
National Weather Service Des Moines IA
503 AM CDT Thu Apr 20 2017

Low pressure moved across the state last evening and exited northeast
Iowa during the early morning hours. Showers and thunderstorms were
common ahead of the low last evening with heavy rain, some small hail
and strong winds. One tornado was reported near Carroll with some
damage to buildings south of town. Otherwise, a few other reports of
hail and wind damage were reported in central Iowa as the storms moved
northeast. Much of the precipitation had ended by the early morning
hours with cooler air filtering into the state. Winds had become
modest from the northwest at 10 to 20 mph with gusts of 30 mph for
much of the state. Early morning temperatures ranged from the lower
70s in southeast Iowa just ahead of the cold front. Mid 40s were
common in northwest Iowa as colder air pushed into the state.

The system which affected Iowa last night will continue to push north
and east today. Showers and thunderstorms are forecast across the
southern Great Lakes into the Ohio River Valley where some severe
weather is expected by this afternoon. Meanwhile, high pressure will
build into the Plains with lighter winds and some partly sunny
conditions. The high will push into the upper Midwest by Friday as a
storm moves through the central Plains. Precipitation associated with
that system will persist from Friday into early Sunday from Kansas
into central and southern Missouri. Meanwhile, much more seasonal
temperatures are expected across the upper Midwest with dry
conditions into the weekend including much of Iowa.
