EF1 tornado in Pike County, Illinois

The tornado began about 1 mile NNW of Valley City, IL. Along County Highway 21, trees were uprooted and a mobile home lost its roof and sustained wall damage. The tornado continued to the northeast, crossing County Highway 21 twice, before lifting. Along this path there was significant tree damage along the east side of Highway 21. Overall, the tornado was rated EF1 with a path length of 0.6 miles and a max path width of 110 yards. No injuries or deaths were reported with this tornado.

By late morning much of the rain shifted north and east of forecast area allowing partial

clearing to destabilize the atmosphere. Steep lapse rates due to relatively cold mid level temperatures southeast of the upper level low combined with strong low-mid level wind shear due to an 80-kt mid level wind max southeast of the upper level low. This led to the development of isolated low topped supercells along the northward moving warm front and ahead of the eastward moving cold front. Eight tornadoes were surveyed over WFO LSX's forecast area.
