I'm amazed you're having 85 degree evenings in Iowa City in mid April.
Is this typical?

No! We beat the temperature record for yesterday by over ten degrees.
Very unusual weather, for April.

Glad to hear to and yours came through it alright.

Look at the temperature difference before and after the storm. That is
what causes the rotation.
Remember that NEXRAD has a minimum eight-minute lag between the actual
weather and what is diplayed. Your local doppler radar displays the
actual conditions.
When the airport gets de-fodded, take Atlas up and photograph the damage
path. It will not be difficult to determine where it begins and ends.

The path of the tornado that hit the norther Cincinnati suburbs ten(?)
years ago was incredibile to follow. The industrial park behind my
sisters house was leveled. An industrial building 50 yards behind her
house disappeared, yet the trees on the fenceline and her house were
unscathed.
That storm prompted every member of our family to purchase weather
radios. Radio Shack had waiting lists for every model for over six
months.
