Today: Another unseasonably warm day is forecast with highs in
the low to mid 80s for the last day of September. Ridging aloft
and high pressure at the surface over the Mid to Upper
Mississippi Valley will keep the local area dry as well.

Tonight and Tuesday: A shortwave trough moving across the Upper
Midwest and northern Great Lakes will drag a cold front through
eastern Iowa and northwest Illinois late tonight into Tuesday
AM, ushering in a more fall-like air mass. The passage of the
front will be accompanied by gusty NW winds around 30 mph which
will continue into Tuesday morning. Forecast highs on Tuesday
are in the upper 60s to low 70s.
