| Episode narrativeepisode_narrative | A dynamic pattern was once again in place over the central U.S. A strong surge of moisture took place during the day on the 26th, with precipitable water values rising to over 2 inches by evening. The airmass became very unstable with the lifted index falling to around -8 and CAPE in excess of 4000 J/kg. The atmosphere was quite warm with the freezing level between 15,000 and 16,000 feet. CAPE in the -10 to -30 C layer of the atmosphere was around 600 J/kg. Downdraft CAPE was quite high, in the 1200 to 1500 J/kg range. Considerable shear was available with shear in the 50 to 65 kt range. Meanwhile, a strong mid level trough of low pressure approached the central U.S. along with a moderate cold front approaching from the northwest. During the night, the low level jet increased to 70 kts, further feeding the thunderstorms. A large complex of thunderstorms developed across South Dakota into Nebraska. It moved southeast into the rich air over Iowa and accelerated, becoming a derecho. A large area of high winds developed with widespread wind gusts of 60 to 75 MPH, mainly over the southwest half of the CWA. The storms also produced hail at most locations as it passed. Most of the hail was around an inch or so in diameter. A smaller area of thunderstorms formed over southeast Iowa, ahead of the main area. These storms produced hail up to golf ball in size, along with 60 MPH winds during the early evening. The largest hail reported was 2 inches in diameter in Cincinnati in Appanoose County. The storms produced copious rainfall in spite of their rapid movement. Flash flooding was reported in Union, Adair, Davis, and Adams Counties. For the most part the flash flooding was relatively minor, limited to water flowing rapidly over roads. In Davis County at Bloomfield, water blew off manhole covers and was deep enough to nearly reach the tops of car roofs. The thunderstorm winds caused widespread damage to trees and power lines. A semi-truck was overturned on Highway 141 west of Woodward by the winds. Another was overturned in Carroll County on U.S. highway 30. A high wind event also took place with the storm complex as a wake low formed. Strong easterly winds developed with wind speeds in the 60 to 75 MPH range common. The strongest winds occurred in Webster County at Callendar. Winds of 80 to 90 MPH blew down mailbox posts, blew down trees onto houses, and picked up a swing set and blew it through the window of a house. Tree and power line damage was quite widespread over a 7 county area. One tornado touched down in Carroll County south of Halbur. A narrow swath of damage occurred from about one quarter mile south of the intersection of Granite Ave and County Road E53, with the roof blown off a hog confinement building just southeast of the intersection. Minor damage continued along a path 2.5 miles long to the east with another roof partially blown off of a Morton building just southwest of the intersection of County Road E53 and Ivy Ave. The tornado lifted about one quarter of a mile southeast of the intersection. |
