Read the full account →More heavy rainfall was seen across the area, primarily situated over the northern third of the state, as a surface boundary sat across central Iowa and a shortwave moved through the upper level flow.
Read the full account →The weather pattern changed only slightly from the day before. A strong upper level trough was in place to the west of Iowa with the surface low and cold front near the western Iowa border, and the warm front bisecting the state.
Read the full account →A very moist airmass was in place with warm cloud depths near 4.5 km. Precipitable water values were in the 2.2 to 2.4 inch range over a large part of Iowa. A thunderstorm complex formed over eastern Nebraska during the evening of the 22nd.
Read the full account →A weak semi-stationary boundary remained draped across Iowa in the overnight hours of the 20th into the 21st, which acted as a focus for initial storm development. Storms early in the evening moved off to the southeast and was relatively quiet until the low level jet kicked in.

Read the full account →An ideal setup was seen across northern and central Iowa for repeated rounds of heavy rainfall and severe weather. A weak warm frontal boundary stalled out across the area as it transitioned to a stationary boundary and allowed multiple rounds of storms to initiate on the 21st…
Read the full account →During the evening of the 25th, a number of storms were able to initiate along a relatively stationary boundary situated across southern Iowa. On the warm side of the boundary surface conditions were in the mid 80s for temperature and upper 60s to low 70s dewpoints.
