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

Summary:

Numerous thunderstorms developed across northern Illinois, especially along the I-55 corridor, during the late morning on Thursday, March 14. These shifted east through the early afternoon into northwest Indiana. Several of these storms were supercells, and what meteorologists call "low-topped", in that they were not particularly deep as in late spring or summer. However, due to a potent weather system over the Plains, a very strong atmospheric wind field had enveloped the area helping storms to have a wind threat and rotate, bringing tornado potential. A brief EF-0 tornado occurred near Lowell, Indiana. In addition, very cold air aloft resulted in many storms having at least small hail, and a few bringing large hail. Strong non-thunderstorms winds then followed through the afternoon and evening.
