After sub-zero temperatures/dangerous wind chills – blowing and drifting snow today/tonight

Overnight temperatures bottomed out between 5 and 10-degrees below zero across the Chicago area, and early morning wind chills were about as forecast in the dangerous -15 to -25-degree range. Most temperatures had risen to or above freezing, with clouds overspreading the area and winds were already gusting over 30 miles per hour by 8AM CST this morning.

A winter Weather Advisory is in effect for our area today and tonight calling for hazardous travel conditions to develop due primarily to blowing and drifting snow already on the ground today along with the possibility of some light snow this afternoon. Then additional snow and blowing snow should occur tonight.

 Southwest winds are expected to continue to strengthen – gusting consistently over 40 miles per hour this afternoon – picking up the dry snow off  the ground and carrying it across roads – especially in open areas – making for unexpected slick spots. These conditions will continue into the nighttime hours.

 A cold front is expected to sweep down from the northwest – passing through northeast Illinois, southeast Wisconsin and the northwest Indiana later tonight. Snow will develop ahead of the cold front – winds will remain strong – shifting to the northwest after the front passes a given location. New snow accumulations of 1 to 3 inches are forecast with deteriorating travel conditions likely overnight. Snow should let up and end from the west Saturday morning.
