What happened

The episode as NWS DMX wrote it up.

An upper level trough produced widespread showers and thunderstorms across the Midwest. Meanwhile, isolated storms developed behind the primary area of convection while instability remained high and shear was still in place to help organize storms. Most of these remained sub severe, however one storm just south of Des Moines produced up to golf ball sized hail. Later that evening a cold front swept across the area. A few non sever thunderstorms developed along the front, one of which produced a brief funnel cloud in northeast Iowa.

What forecasters said that day

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Des Moines, IA wrote its last area forecast discussion before the first event at Jun 24, 5:41 AM CST, 1 hour 16 minutes earlier.

.DISCUSSION.../Today through Thursday/
Issued at 357 AM CDT Fri Jun 24 2022

Key Messages:

-Scattered non-severe storms this morning. Convection more
 widespread tonight with some wind and hail threat west along
 locally heavy rainfall north.
-Some lingering storms southeast on Saturday.
-Much cooler and less humid Sunday into Monday.

General convection developed late last evening along the leading
edge of moisture gradient in western Iowa and has progressed east
overnight with the gradient. This convection is likely to persist
for several more hours until mid to late morning before the
weakening low level jet leads to gradual weakening of the storms.
Lingering cloudiness today is expected to limit temperatures,
especially in the south but should more sun than expected occur,
then readings will be too cool.  The tightening of the pressure
gradient with the deepening low across the Plains should help winds
to increase nicely from the south by afternoon with some gusty
conditions as well, especially in the west.

By tonight, shortwave energy passes from the Rockies into the Plains
with bulk lift helping to support convection along a boundary from
the Dakotas into Nebraska by mid to late evening. The instability
axis is strongest west of Iowa where severe potential remains
highest.  Overall soundings are not overly impressive into much of
Iowa tonight with the best overall profiles in the northwest.  Even
there mid level flow is relatively weak into tonight although it
strengthens with time as the shortwave moves into the Plains.
Generally, the severe threat remains quite limited to the northwest
late this evening with some wind and hail concerns.  Otherwise,
moisture transport is expected to be rather decent with 850mb flow
of 40-50kts into the convection with PWATS in excess of 1.5".
Locally heavy rainfall may well be the bigger concern with the
development of any convection ahead of the main push of storms
overnight.  This main push passes quickly east overnight with much
of the forecast area in the clear after 12Z on Saturday morning.

The boundary passes through the state on Saturday with much drier
and cooler air on the backside.  However, the southeast remains in
the warm sector for much of the day with heat index values
approaching 100 by early afternoon.  Storm development also is
possible by mid to late afternoon in the far southeast prior to the
frontal passage with a limited threat of a strong to severe storm.
Once the boundary clears, the weather is expected to be quiet into
Sunday with cool temperature and relatively low dewpoints.  This
pleasant weather remains into Monday and even Tuesday although warm
advection will be underway by then.  The threat of a few storms
clipping the far northeast is possible by Tuesday afternoon with a
cold front grazing northeast Iowa but the bulk of forcing and action
remain in Minnesota and Wisconsin.  A return to very warm and humid
conditions is then expected by midweek as south to southwest
winds transport moisture northward into the state.

.AVIATION.../For the 12Z TAFS through 12Z Saturday morning/
Issued at 641 AM CDT Fri Jun 24 2022

Scattered convection is expected to persist across portions of
central and southern Iowa. Main impacts will be MVFR to IFR
ceilings and visibilities in and around the showers and storms.
Otherwise, VFR conditions are forecast for other areas. Winds are
expected to increase from the south during the day with gusty
conditions, mainly in the west. Storms are forecast to move across
the state tonight with most impacts across the northern half of
the state including reduced visibilities and ceilings in and
around storms.
