The Winter Solstice occurs at 6:04 a.m., making this the shortest day of the year in Chicago, and it will be by far the coldest this winter. With temps in the single digits and winds gusting at times in excess of 40 m.p.h., dangerous wind chills -20 to -25 degrees will hold over the area today and tonight. Frostbite and hypothermia are a very real threat unless proper precautions are taken. The frigid high pressure air mass will begin to weaken Monday night.
TEMPERATURES MODERATE MIDWEEK
By Wednesday, temperatures are to reach more seasonable levels (Normal high: 33°). Even so, there is a good chance Chicago's snow cover will persist through Christmas.
