Today: Showers, mainly before 2pm. High near 51. Breezy, with a north wind 15 to 20 mph, with gusts as high as 45 mph. Chance of precipitation is 100%. New precipitation amounts between a tenth and quarter of an inch possible.

Tonight: A 10 percent chance of showers before 7pm. Mostly cloudy, with a low around 44. North wind 10 to 15 mph, with gusts as high as 30 mph.

Scattered showers will continue for most across the area through at least mid-morning with the far backside of this system yet to make its way into the Chicagoland area. Rain could last as late as the early evening for those in the far eastern portion of Chicagoland. The highest rain coverage for the remainder of the event should be along and north of I-80.

The heaviest rainfall and the potential for thunderstorms is just about finished for this rain system. The biggest concern in the short term for Monday are the strong winds and resulting lake conditions later this morning. A tightening pressure gradient on the backside of this storm system will result in a blustery boundary layer with guidance suggesting sustained winds upwards of 50 MPH winds around 9 AM to 11 AM. A period of strong winds will persist between 7 AM and 1 PM CDT. A wind advisory has been issued during this time period with 45-50mph gusts appearing likely. Wind gusts should diminish as we approach the evening.

Areas bordering the Lake Michigan could see some spotty showers thanks to some decent northeasterly flow and a little bit of lake-induced instability. These lake-effect showers could last as late as early Tuesday morning.

Tuesday, Chicagoland is forecast to be rain-free with seasonable highs in the middle and upper 50`s with more sun than clouds. — NWS Chicago with edits by CARDINAL NEWS
