Chicagoland Weather: Wet Week Ahead, More Flooding Possible for Chicago Area

After getting drenched by heavy rain last week, a wet week is ahead for the Chicago area with two to three more inches of rain in the forecast and the possibility for flooding .

Two strong low pressure area will affect the area -- the first on Monday through Monday evening and then another on Wednesday through Thursday, according to the National Weather Service. Heavy rain rates and significant rainfall amounts are expected with both storm systems.

For the first system, rainfall amounts approaching or exceeding one inch could occur along the
Interstate 55 corridor though significant rain remains possible area wide. For the mid- to late-week system, heavy rainfall is possible area wide depending on the track of the low pressure area.

Between the two storms, at least parts of the area could experience total rainfall amounts of 2 to 3 inches or more. Given the saturated ground and ongoing minor river flooding from heavy rains on March 30, this week's wet weather could result in flooding of low lying areas and renewed sharp river rises, according to the National Weather Service.

Isolated thunderstorms are also possible on Monday and Wednesday and there is a slight chance of rain on Tuesday morning. High temps between 51 and 64 degrees are in the forecast on Monday while high temps between 55 and 61 degrees are in the forecast on Tuesday and temps between 48 and 58 degrees are expected on Wednesday.

Chillier temperatures and high wind gusts are in the forecast for Thursday and Friday.
