Light Showers Sunday Evening, Heavy Rainfall Possible Monday Morning

Sprinkles and light rain showers have developed Sunday evening but will remain light and scattered through the rest of the night. Rain will become a little more heavy and steady by Monday morning as moisture increases into northern Illinois and low pressure approaches from the west.

Moisture in the atmosphere will increase to over one inch by Monday morning, leading to the

possibility of heavy rainfall throughout the morning commute. Instability will remain limited, so only embedded thunderstorms are possible.  Severe weather is not expected during the morning.

The rain will last through mid to late morning with a little break in some of the heavier activity for the afternoon. A warm front will quickly lift north during the late afternoon increasing the dew point temperature, as well as the humidity. A cold front will be quick to move in from the northwest Monday night leading to a second round of thunderstorms during the evening. While most of the strong to severe thunderstorms will remain positioned to our southwest throughout the day, some storms Monday evening could have a strong wind gust or two associated with them. Heavy rain will continue to remain a threat through Monday night.
