Wider weather episode

An unseasonably warm and humid airmass was in place across central Illinois during the morning of December 28th characterized by temperatures and dewpoints in the lower 60s. As a 1000mb low over southeast Iowa and its associated cold front began pushing eastward, a cluster of severe thunderstorms developed west of the Illinois River across Fulton County, then tracked eastward across portions of Tazewell and Woodford counties before eventually weakening. This cluster of storms produced an EF-1 tornado south of Groveland in Tazewell County, as well as scattered reports of wind damage and hail up to the size of quarters.
