After a bitterly cold morning around Chicago, temperatures will warm into the upper teens and lower 20s under partly sunny skies.
High pressure will continue to move south of Chicago resulting in more of a southwesterly wind. This will keep temperatures a good 10-15 degrees warmer tonight as lows dip into the upper teens.
Friday will be the warmest day since this cold snap began last Thursday as highs approach 30 degrees in some spots.
Low pressure will move north out of Texas and Oklahoma Friday night bringing periods of snow through early Saturday. Right now areas south of I-80 will see the greatest accumulating snow, mainly 2-4" with 1-2" from the Chicago metro to areas north and west.
Friday: Partly sunny and warmer with some snow overnight. Highs: 25-30 Lows: 20-25
Saturday: Mostly cloudy and breezy with snow likely early. Highs: 28-33 Lows: 10-15
