| episode_narrative | An intense low pressure lifted out of the south central U.S. into western Iowa during the afternoon hours of the 31st. The upper low virtually captured the surface system by late afternoon. Thunderstorms formed along two boundaries. The first was a warm frontal boundary that lifted into central Iowa by early afternoon. The second was a strong dryline that advanced into southwest and central Iowa by the late afternoon hours. With the steep lapse rates, there was little in the way of CIN and once the clouds began to break. Surface Based CAPE was in the 1000-2000 J/kg range with CAPE in the -10 to -30 C. layer around 200 J/kg. The freezing level was quite low, ranging from 8,700 to 10,000 feet across the CWA. Lifted indices fell to the -6 to -9 C. range by the mid afternoon hours. In spite of the LCL being quite low, in the 500 to 1000 meter range, there were several reports of funnels, but no confirmed touchdowns. Thunderstorms formed in two lines. The first was along the warm front across central Iowa. The second along the dryline. There were numerous reports of pea to marble size hail and surprisingly few reports of larger hail. The hail that did fall was in the three quarter to one inch diameter range. One inch diameter hail covered the ground in Davis County at Bloomfield. Some damage was done to vinyl siding in the city of Bloomfield as well. A few of the storms produced high winds with tree damage and some building damage. A roof was blown off a shed in Polk County in Pleasant Hill. Outbuildings were destroyed by another storm in Story and Marshall Counties, and a garage was blown over in Marshall County in the Marshalltown area. High winds from the dryline storms caused damage in Waukee with damage to house siding and a metal fence in the area. |
