As a large storm system approaches from the west we will see southerly winds usher in an increase in Gulf moisture which will saturate the atmosphere overhead.
A line of gusty storms and heavy rain will form overnight and blanket the Chicago area late tonight and through much of Sunday.
Rainfall amounts will be highest north of I-80 and could range from 1.5" - 3.25".
Once the storm passes Sunday afternoon we will see an increase in winds from the west ahead of an area of high pressure.
