Warmer weather is expected Wed and Thur. Increasing moisture over a melting snowpack will lead to fog Wed night into Thu. pic.twitter.com/Ig2I30Ot71— NWS Chicago (@NWSChicago) February 13, 2018
Take a look at northern Illinois & northwest Indiana from space via satellite on Monday. The deep snow cover vs no snow stands out, but also check out the ice on Lake Michigan. Whether a fan of all this snow or not, one has to appreciate this view from high above! #ilwx #inwx pic.twitter.com/s7jeuEfqIc— NWS Chicago (@NWSChicago) February 13, 2018
Milder air starts moving in today. Areas with deepest snow cover will see the cooler temps in the range while those with little snow will realize the higher. Main item of interest this week is fog likely developing during Wed eve & persisting into early Thu. #ilwx #inwx pic.twitter.com/zTWEm1VBSR— NWS Chicago (@NWSChicago) February 13, 2018
