Forecasters say that a temperature record that was set in the 19^th century for Chicago could be in danger over the next week.

The polar vortex bringing cold temperatures back to the Midwest and Upper Plains states could cause Chicago to see a high temperature for Wednesday stay below the record for the date of 10 degrees set in 1888.   The standing low record for the date is 1 below zero, but that was not broken overnight.  It could still be broken later tonight.

Wind chill is also a major problem in the city with some areas reporting a wind chill more than 20 below zero.

The problem is predicted to be compounded by a second wave of cold air from the arctic that will force temperatures as far as ten below zero with wind chills greater than 30 below zero.

Forecasters say it’s possible the record low maximum temperature for Thursday, also 10 degrees set in 1888, could fall because of the second blast of cold air.  The record low on February 28^th of zero degrees set in 1884 is also likely to fall.

The blast of cold air is expected to keep driving down temperatures for over a week.
