Remember that cold spell a few weeks ago? The one that froze your cheeks and feet and you felt clear to your bones?
If you don't remember, Mother Nature is forecast to send you a reminder in the next few days.
While today's forecast is in the twenties, the mercury is forecast to again plummet. It will dip below zero tonight, with wind chill making it feel like minus 20, and Tuesday's high will only reach about 7 degrees, according to the National Weather Service.
The average high will stay in the single digits or low teens through at least Friday, when the situation may slightly improve and reach the low twenties, according to forecasters.
If there's good news in all of this, it's that you likely won't have to go outside and shovel one heck of a lot. The forecast calls for a few flurries today, and a 20 percent chance of snow Wednesday and Thursday.
Two days of bitter cold temperatures Jan. 6 and 7 that shuttered schools and made travel dangerous, but meant an economic boon for auto shops and furnace repairmen, marked the coldest temperatures in the Chicago area in more than 20 years. The coldest temperature in the metro area, minus 20 degrees not including the wind chill, was recorded in the City of McHenry. Local temperatures averaged between minus 35 and minus 45 with the wind chill.
The cold snaps are part of a very snowy winter that has strained local governments' supplies of road salt.
