Weather Summary for Iowa
National Weather Service Des Moines IA
526 AM CDT Thu Sep 21 2017

Thunderstorms developed over southeast Iowa Wednesday evening and
moved little through the overnight hours resulting in very heavy
rainfall amounts from Ottumwa toward the Quad Cities. Rainfall amounts
of 5.59 inches were reported on the south side of Ottumwa with doppler
radar estimates as high as 7 inches east of town. Otherwise skies were
clear farther north and west. Early morning temperatures varied quite
a bit heading toward daybreak due to the stationary front causing the
storms with readings from the lower 50s northwest to around 70 far
southeast. Winds were typically light from the east or northeast,
except near storms.

These early morning storms should diminish shortly after sunrise with
the main weather story across the region turning toward unseasonally warm
and humid conditions with little in the way of precipitation through
the weekend. Highs will often be well through the 80s to lower 90s
with dewpoints to 70 or more pushing heat indicies several degrees
higher. Heat indicies may reach well through the 90s central and south during
peak heating of the afternoon increasing the potential for heat
stress and heat illnesses.
