Weather Summary for Iowa
National Weather Service Des Moines IA
1110 AM CDT Fri Jul 22 2016

Showers and thunderstorms exited southeast Iowa earlier this
morning. By late morning, narrow bands of showers had developed
over portions of central into south central Iowa. Otherwise, skies
were partly to mostly sunny. Early morning lows were in the 70s
across the state, warming into middle 70s east to the middle and
upper 80s west. South winds were 5 to 15 mph. Heat indices ranged
from the middle 80s in the rain cooled air over the southeast to
the 90s west.

A frontal boundary stretched across South Dakota into northern
Iowa and central Wisconsin this morning. Dangerous heat will
continue today with heat index values once again reaching the 105
to 115 range. Isolated showers and thunderstorms are forecast,
mainly early this morning and again in the late afternoon and
evening. Thunderstorm chances will then increase from late tonight
into Saturday night, mainly across northern Iowa, providing a
little relief from the heat that will continue in the south.

Relief from the heat will finally come early next week behind a
cool front moving across Iowa on Sunday. By Monday and Tuesday
high temperatures will be in the 80s with morning lows in the 60s
and generally dry weather. Rain and thunderstorm chances will then
return in the latter half of the week.
