The big warm-up continues! Chicago's snow continues to melt. What was once a 22" snowpack is down to 14" Sunday morning--and continues melting. The breadth of this warm-up is stunning. Check out this 24 hour temperature change map--warming has taken place almost from coast to coast. The snow cover across the Lower 48 has shrunk from 64.9% of the country Thursday to 63.1% Fri, 46.9% Sat and 42.4% this morning. Watch the snow melting Saturday thru midnight last night on this animation from NOAA's National Operational Hydrologic Remote Sensing Center
