Loop of pressure and pressure change. Click to enlarge.

Image and the following description courtesy of NWS Chicago.

Mean sea-level pressure (left) and 3hr mean sea-level pressure change (right) looped hourly from [3] a.m. through [8] p.m. on April 2nd.  The low pressure magnitude of 997 mb over Milwaukee during the morning is anomalously low especially for a springtime "Clipper" system, and such deep lows have an inherent stronger wind field due to the pressure gradient force.  In addition, the rapid speed of this low (which is common for "Clipper" systems) induced a high rate of change in pressure as shown by the right loop.  This strengthened the issalobaric component to the wind.  This is strongest in the zone between the maximum pressure falls and rises, which passes directly over northern Illinois and northwest Indiana.
