Read the full account →A rather complex weather situation was in place over Iowa. An outflow boundary drifted south across the state during the day from convection that had taken place earlier in the day. The boundary became stationary over the southern sections of the state.
Read the full account →A weak flow pattern was located Iowa. Abundant low level moisture combined with the strong solar heating and passage of a weak trough of low pressure resulted in thunderstorm development. The storms were not severe, but they also were not moving very fast.
Read the full account →A very active weather pattern was in place over the central U.S. A strong west-northwest wind flow was in place over the state. Meanwhile a warm front was lifting north from the southern Plains.
Read the full account →The situation remained very active as the meteorological stage was about the same as the previous night. Thunderstorms formed as an upper level short wave moved east across the area. At the same time, Iowa fell into the right entrance region of the upper level jet.
Read the full account →A very unstable airmass was over Iowa during the morning hours of the 5th. CAPE values were well over 4000 J/kg at sunrise with lifted indices near -10 C. Thunderstorms erupted in two clusters around 1200 UTC.
Read the full account →A nearly stationary frontal boundary was located to the north of Iowa during the day on the 9th. Very rich air was pumped north into the state with surface dew point temperatures reaching the mid 70s to low 80s by the late afternoon and evening hours.

Read the full account →After a brief break of about five hours, thunderstorms began to erupt in Iowa once again. As had been the case over the course of the previous several days to the north and west of Iowa, thunderstorms developed during the mid afternoon and became supercells within a short…
Read the full account →Following the passage of the powerful storm system earlier in the weekend, another round of severe weather was on tap for the state. The cold front from the previous storm did not move all that far to the south of Iowa.
Read the full account →For the second night in a row Emmet County was hit by heavy rains. Severe thunderstorms formed to the west of the area and moved into Emmet County by the late evening hours.
Read the full account →A nearly stationary front extended west-southwest to east-northeast across Iowa. Thunderstorms fired repeatedly along this front during the night of the 1st into the morning of the 2nd.
Read the full account →A very weak cold became stationary to the south of Iowa during the late afternoon of the 2nd and early morning of the 3rd. Once again, elevated convection developed in Iowa as the low level jet brought moisture northeast into Iowa.
Read the full account →An upper level low pressure dropped south out of Minnesota into Iowa during the night. Though the airmass over Iowa was typical of early to mid July, however the upper level low pressure was more typical of the cold season.
