Weather Summary for Iowa
National Weather Service Des Moines IA
1049 AM CDT Wed Jul 19 2017

Early this morning, showers and isolated storms skirted along the
state line in southwest Iowa as well as a small cluster of storms that
moved from northwest and central Iowa. Otherwise, skies were mostly
sunny across most of the state. Early morning low temperatures were in
the upper 60s northwest to the middle 70s central. Temperatures heated
up by late morning with readings reaching the lower and middle 80s.
South to southeast winds were 5 to 15 mph. Heat indices were in the
upper 80s and lower 90s over the southern half of the state.

A frontal boundary was draped across the upper midwest, stretching
from Iowa into the Great Lakes region. The overall weather pattern has
not changed. We will continue to see hot and humid conditions across
central Iowa and areas south. Excessive heat warnings and heat
advisories are in effect. Across northern Iowa and locations north,
the heat and humidity will not be quite as bad however a frontal
boundary waffling across the area will bring chances for
thunderstorms. Saturday night into early next week we will finally
see a pattern shift as high pressure builds to the west with low
pressure over the Great Lakes. Highs through Saturday will be in the
mid to upper 90s with upper 80s north. Heat indices south through
Saturday will be in the 105 to 110 range. Sunday into next week,
temperatures will be in the upper 70s north to the mid 80s south.
