are expected ahead of this front early wednesday morning, with
gusty northwest winds behind it wednesday afternoon and night.

pressure of 30.4 inches over illinois and indiana. another period
of elevated southwest winds will occur thursday night into friday
as another low pressure trough around 29.8 inches crosses the
