| Episode narrativeepisode_narrative | A cold front moved into Iowa during the afternoon from the northwest. The airmass became very unstable ahead of the front. Temperatures rose into the upper 80s to low 90s, with dewpoint readings in the upper 60s to lower 70s. CAPE increased to 4000 J/kg by late afternoon with a lifted index between -10 and -18 C. Downdraft CAPE was between 1200 and 1700 J/kg, with CAPE in the -10 to -30 C layer of the atmosphere in the 700 to 900 J/kg range. The freezing level was very high, around 15,000 feet, with the LCL at 1250 meters. Deep moisture was available for the system, with precipitable water values around 1.6 inches. Little shear was available with only 20 kts of effective shear. A line of thunderstorms formed along the cold front during the afternoon and tracked southeast into Iowa. Several of the storms produced hail from the size of quarters to the size of golf balls. Funnel clouds were also reported with a few of the storms. As the thunderstorms continued into the later afternoon and evening, wind became a more dominant factor. Numerous trees were downed by high winds in Wright and Franklin Counties. The storms developed southwest with a line of significant thunderstorms extending from northeast into central Iowa by early to mid evening as new storms formed on the outflow boundary of the original development. The storms continued to produce quarter to golf ball size hail and wind gusts of 60 to 70 MPH. The winds caused spotty building damage, including a barn near Story City. Six horses that were inside were killed. The barn was east of Boone, where buildings and power lines were destroyed at the Central Iowa Expo grounds. Two inch diameter hail was reported in parts of Wright and Boone Counties. A heat burst produced 73 MPH winds in Marion County at the Knoxville Airport. The temperature rose from 70 to 84 in 15 minutes, and the dewpoint dropped from 63 to 48 in 10 minutes. |
