The setup was not spectacular for sustained or widespread severe weather, but did lay the ground for some isolated issues. SB/MUCAPE values built up into the 2000-4000 J/kg range by the early afternoon with the help of dew points into the low to mid 70s and at least semi-supportive lapse rates. While there was not large scale lift, there was a weak boundary laid out across central Iowa from west to east, in part remnants from previous night and morning storms. Fortunately, effective bulk shear values were below 30 knots, reducing the potential for widespread severe weather potential. All in all, with unstable conditions and weak flow, heavy rainfall and flooding become the primary issues for the day though a few other reports including damaging winds and a funnel cloud were also reported.
