| Episode narrativeepisode_narrative | The seasons first major severe weather event took place as a strong upper level low pressure lifted north into the central U.S. This was ahead of a strong upper level low pressure system over the southwest U.S. A warm front lifted north across the Des Moines CWA with moist and unstable air pushing into the state. There were several rounds of convection. The first developed over northern Iowa during the mid afternoon hours and moved north into Minnesota. A break in the thunderstorm activity took place before the next round moved into southwest Iowa and spread north and east during the evening. The atmosphere became unstable with highs in the 80s and dewpoints in the low to mid 60s by afternoon. CAPE, though not excessive, was sufficient with 1000 to 3000 J/kg available. CAPE in the -10 to -30 C layer of the atmosphere was between 300 and 600 J/kg. In the late afternoon hours around 500 J/kg of downdraft CAPE was present, and it increased to around 900 to 1100 J/kg during the evening hours. The shear increased as well with 25 to 40 kts available at the beginning of the event, and 50 to 60 kts by the end. Precipitable water values increased to 1.2 to 1.5 inches. The LCL was relatively low, around 1000 meters. The freezing level was relatively low, around 11,900 feet. The storms produced heavy rain and large hail initially. Flash flooding occurred first in Crawford County in western Iowa with over two inches of rainfall in about an hour, causing water to flow over Highway 141. The event became a wind and hail event for the most part with winds gusting to 60 to 80 MPH across a large part of the CWA and hail up to 3 inches in diameter in Adams County. The largest hail was northwest of Carbon in Adams County, where 2 to 3 inch diameter hail fell. Reports indicated enough hail fell to completely cover the ground. Numerous reports of 1.5 inch hail were received. Three tornadoes touched down in central Iowa. Numerous reports of winds of 60 to 80 MPH were received all along the line of thunderstorms. High winds blew a semi truck off the highway and blew it over west of Earlham in Madison County. There was considerable tree damage reported with some damage to outbuilding, barns, and a few houses. |
