A line of showers and thunderstorms developed during the late afternoon of Friday, May 13, 2022 generally along and east of the Mississippi River in northwest Illinois. Some thunderstorms did become severe along that line, and produced all modes of severe weather including hail up to one inch, wind gusts to 60 MPH and two landspout tornados. One occurred near Good Hope IL, with the other just to the south of Monmouth IL. Some reports of flooding were also received, especially near Roseville IL.

Storms gradually weakened in strength through the evening, and dissipated just before midnight
