Parts of Chicagoland are expected to brace for heavy rain later Tuesday into Wednesday.

The remnants of Tropical Storm Beryl are moving across southern Illinois Tuesday morning and are expected to reach Chicagoland by Tuesday afternoon.


It will bring with it tropical rains, which have the potential to drop heavy rains very quickly.

Meteorologists use a measure called the precipitable water level, which basically measures the moisture in the air. A precipitable water level of 2 inches is considered very high, indicating the potential for heavy rain.

Areas southeast of Chicago and northwest Indiana are below this level and will see the heaviest rainfall totals on Tuesday and Wednesday, with up to 3 to 5 inches.

This type of heavy rain also reduces visibility and increases the potential for flooding, so Cook, Will, Kankakee and Grundy counties in Illinois and all of northwest Indiana will be under a flood watch from 4 p.m. Tuesday to 1 p.m. Wednesday.

However, areas to the north and west are expected to receive much less rain from the remnants of Beryl. Meanwhile, high temperatures around Chicagoland on Tuesday will reach the low 80s.

Then, very warm and humid air will move into the region through the weekend and into the weekend, with dew points reaching the 70s and air temperatures around the 90s.
