CHICAGO — Arctic air is tightening its grip on Chicago with the prospect of single–digit highs and subzero lows in the days ahead.

Tuesday’s highs in the low and mid 20s occurred just after midnight with readings steadily falling through the day despite abundant sunshine.

By evening readings were in the single-digits headed for negative territory by Wednesday morning.

Wednesday’s highs will struggle to reach 10 to 15 and quickly drop below zero again Wednesday night and climb to just zero to 5 Thursday. Gusty west winds will add to the frigid conditions with wind chills as low as minus 25.

A Wind Chill Advisory is in effect beginning at 9 p.m. tonight until 10 a.m. Thursday.  Air temps will drop below zero tonight. The Wind Chill Thursday morning will be 15-25 degrees below zero.

The cold will ease on Friday as the mercury rebounds to about 20, but the price for the warm-up will be another winter storm that threatens Chicago with its third accumulating snowfall of the season Friday afternoon into Saturday.

A brief surge of warmer air could change the snow to a wintry mix Saturday before a new arctic blast sends temperatures crashing, changing the precipitation back to snow.
