Weather Advisory Upgraded to a Winter Storm Warning for DuPage County

The National Weather Service has issued a winter storm warning for DuPage County through 6 p.m. Sunday, Jan. 5. The warning area also includes the counties of Cook, La Salle, Kendall, Grundy and Will. 

Snow will develop Saturday afternoon, continuing into Sunday, and computer models are now indicating we may get 5 to 10 inches of new snow.

The Weather Service has been updating its predictions frequently since Friday night. The previous weather advisory issued earlier on Saturday has been replaced with this new warning, which was posted Saturday at 10:45 a.m.

Periods of moderate to heavy snow could lead to hazardous travel conditions, and airport delays are likely, according to the Weather Service. Brisk northwest winds of 15 to 30 miles per hour also could result in blowing and drifting snow, further reducing visibility.

Temperatures, while remaining mild all day Saturday, will drop dramatically on Sunday. Expect to wake up to about 13 degrees and end the day at about -5 degrees. Wind chills will make that feel like about -30 degrees.

The deep freeze continues into Monday, which will see a high of -12 and a low of -15, and Tuesday, which will "warm up" to only 4 degrees. Both days are predicted to be windy, making the wind-chill factor extremely dangerous for anyone outdoors.

Area schools have released notices to parents that they will by Sunday make a determination on whether to cancel school Monday. Elmhurst Patch will share that information as it becomes available.
