| June 1994 | Thunderstorm Wind | Marshalltown | $5,000 | Thunderstorms formed during the middle to late afternoon hours over northwest Iowa. Overall dynamics were weak, however weak moisture advection during the day combined with temperatures warming to around 90 degrees contributed to making the airmass quite unstable. After taking into account the 90 degree temperature and the dew point around the 70 degree mark yielded a CAPE value of over 5000 J-Kg-1 by the late afternoon. The severe storms were confined to a rather narrow area. The first severe weather reported occurred over the far northwest Iowa, where three-quarter inch diameter hail fell at Sibley. The storms drifted southeast and produced hail in Clay County as well. Hail the size of quarters fell southwest of Spencer. Webster County was hard hit with both hail and heavy rainfall. Rain fell at the rate of two to three inches per hour in the Lizard Creek Basin. This caused some minor flooding. Street flooding also occurred in Fort Dodge. No serious flooding occurred however. It was generally urban flooding. Southern Webster County was pelted by hail. In the Harcourt area, dime-size hail accumulated to a depth of two inches. Northwest of Harcourt, golf ball-size hail was reported. Severe crop damage was reported to the corn crop in the area. The storms produced two small tornadoes, although there were several other unconfirmed reports around the central part of the state. One of the tornadoes touched down briefly in Hamilton County south of Webster City. The other was north of Boone, in Boone County. Neither of the tornadoes were on the ground very long and no significant damage was reported. High winds became a problem as the storms moved toward central Iowa. Winds of 60 mph were reported in the city of Boone. High winds took down several large trees in the city of Marshalltown. Most other reports during the afternoon and evening hours were of pea- to marble-size hail and 40 to 45 mph winds. During the evening, a second area of storms that had formed over eastern South Dakota and Minnesota moved into northwest Iowa. Most of them were not severe, though one did drop three-quarter inch diameter west of Le Mars before weakening. |
