While Chicago had seen 60°+ twice already in 2018, today was the first day with 60°+ AND mainly sunny since late November. Oh, and southern California was only in the 50s today so warmer here than there!

Scattered showers are expected across the area overnight through Wed. Rain will then spread across the area Wed night into Thu. Some of this rain will likely change over to wet snow during the morning close to the WI state line. pic.twitter.com/634Lbwpcgb— NWS Chicago (@NWSChicago) February 27, 2018
Several locations across the NWS Chicago forecast area have hit the 60F mark as of 1pm. These temperatures are around 20F above average for late February and are more representative of what would be expected in mid-April. pic.twitter.com/dCVXny0UiA— NWS Chicago (@NWSChicago) February 27, 2018
Sunny, breezy, & unseasonably warm today, then on & off showers late tonight through Thursday. Turning colder, especially lakeside Wednesday pic.twitter.com/qXeDK5m9GZ— NWS Chicago (@NWSChicago) February 27, 2018
