The suburbs received a wintry mix overnight Sunday, with temperatures hovering around the freezing mark. Snowy conditions contributed to numerous crashes on suburban roadways, but there were no immediate reports of serious injuries.
The Illinois Toll Highway Authority reported a crash about 8 a.m. on eastbound Jane Addams Tollway (I-90), west of Roselle Road. The right lane was blocked temporarily, but all lanes were reopened a short time later.
About an hour earlier, the tollway reported a crash on the Reagan Memorial Tollway (I-88) at the northbound exit ramp to Interstate 294. One of the two left-hand lanes was blocked, but all was reported clear by 8 a.m.
The heaviest snow overnight and Sunday morning fell in the far North and Northwest suburbs, with several inches reported. A winter storm warning for McHenry County expired at 10 a.m., as did a winter weather advisory in Kane and Lake counties.
There is a 100 percent chance of precipitation for the rest of the day, according to the National Weather Service, although little or no ice accumulation is expected and only a total snow accumulation of an additional one to two inches is predicted. The high is expected to be 32 degrees, with a north to northwest wind around 10 mph
The forecast calls for snow showers before 1 p.m., followed by more snow showers and freezing drizzle between 1 p.m. and 4 p.m. Snow showers are likely to continue after 4 p.m., mainly before 7 p.m.
More snow is expected early in the week, with a 40 percent chance of Monday, a 30 percent chance on Tuesday and a 50 percent chance for Christmas Day. Cold temperatures also are expected, with a low around zero Monday night, including wind chills as low as -9.
Temps should "climb" to 14 on Tuesday, and a relative heat wave on Wednesday, with a high near 28. Then temperatures should once again drop, with Thursday night temperatures dropping to 1 degree below zero.
