Weather Summary for Iowa
National Weather Service Des Moines IA
440 AM CDT Thu Jul 29 2021

Early morning radar imagery showed pockets of thunderstorm activity
over the state of Iowa. The most notable activity was dropping south
along the Mississippi River in eastern Iowa, but some other isolated
storms were noted in portions of north central and west central Iowa.
The storms are below severe limits, but still producing plenty of
lightning and brief heavy rainfall. Otherwise it is another muggy
night as temperatures have only fallen into the mid 70s to low 80s.

Hot and humid conditions are likely again today across at least the
southern half of the state. The warmest heat index readings of near
105 degrees will reside south of Interstate 80. Folks in northern Iowa
will begin to see some relief as cooler and drier air begins to filter
in from the north. A few thunderstorms are possible by late afternoon
and evening in far southern Iowa.

Our best shot in some time for appreciable widespread rainfall arrives
Friday into Friday night. Showers and storms develop over Nebraska and
move east into the state, likely crossing much of western into central
Iowa. The threat for severe weather is low, but locally heavy rainfall
is possible. After that the forecast dries out over the weekend into
much of next week along with seasonably comfortable high temperatures
around 80 degrees.
