Episode narrativeepisode_narrativeJust as the first MCS from the previous night exited the state, another round of strong convection moved in from the northwest. The airmass remained quite unstable in spite of the activity from overnight as unstable air replaced the airmass over the state and reloaded the atmosphere. CAPE remained in the 4000 to 4500 J/kg range with lifted indices in the -10 to -12 C. range at sunrise. Shear continued to be modest, around 20 kts. There was little change in the freezing level overnight, and it remained just over 13,000 feet. The main mode of severe weather during this event was high winds initially, then more of a transition to flash flooding. There were several reports of winds of 65 to 75 MPH. The highest measured wind speed was a 76 MPH wind gust at the Coon Rapids Schoolnet site. Meanwhile, a severe thunderstorm produced a measured 75 MPH wind gust in Dallas County. Winds gusted to 70 MPH or greater in both Carroll and Greene Counties. Elsewhere, reports of 60 to 65 MPH winds were numerous. Though many of the storms produced hail, there were only a few reports of three-quarter to one inch diameter hail. Flash flooding became a problem as the storms traversed the same areas that were hit the previous night. Flash flooding was most notable in Warren, Monroe, Polk, and Boone Counties. Many streets were flooded with water reported anywhere from 8 to 30 inches deep. A strong high/low couplet developed in the wake of the convection. Winds gusted to around 60 MPH in Boone County in the city of Boone for a short period of time.
