A nearly stationary, west to east oriented, frontal boundary wobbled north and south across northern and central Illinois during the afternoon hours of the 21st into the early morning hours of the 22nd.  The movement of the front was largely modulated by outflows from various thunderstorm complexes.  A few of these storm complexes developed over or moved across central Illinois.  One complex produced two weak tornadoes and several funnel clouds as it developed over east central Illinois during the early evening.  Other storms produced damaging wind gusts, heavy rainfall, and small hail.
