High pressure over northeast Illinois Sunday will give mostly sunny skies,
scattered fair-weather cumulus clouds and mild temperatures. However, events
should change rapidly as clouds thicken overnight with the approach of a
cold front. As the front moves through Monday, warming will occur along with
showers and thunderstorms. Severe storms are possible later in the afternoon
and evening. Behind the front, northeast winds off Lake Michigan will bring
a sharp 10 to 20-degree temperature drop.
Widespread heavy rains possible
As the cold front slows and becomes nearly stationary just a little south of
I-80, atmospheric conditions will be ripe for heavy, potentially flooding
rains north of the front, if repetitive thunderstorms track over the same
areas Monday night and Tuesday.
The southern edge of cool Canadian high pressure should hold over the
Midwest and Great Lakes the remainder of the workweek ,however computer
models indicate low pressure will spread rain back into this area this
coming Saturday.
