This weekend into next week, a series of atmospheric rivers will bring gusty winds, periods of heavy rain, and mountain snow to northern California and the Pacific Northwest. Colder temperatures are in store for the weekend from the Great Lakes to East Coast. Read More >

Overview

Fast Facts:

  • Widespread rain moved over the area on the afternoon and evening of July 15, causing flash flooding, especially just southwest of the area in/near Peoria.

  • Widespread rain amounts of 1 to 3 inches occurred, with an axis over 3" in Livingston County, IL (includes Pontiac).

  • A supercell, or rotating storm, moved from just south of Peoria through Livingston County and into Ford and Iroqouis Counties. This produced a few short lived tornadoes in the NWS Central Illinois County Warning Area just to the southwest, and had visible rotation south of Pontiac as it moved into the NWS Chicago County Warning Area.
