According to the NWS Chicago, confidence is continuing to increase regarding a forecast for a period of steady moderate, to at times heavy snow rates Saturday night and early Sunday morning. The NWS office Chicago opted to issue a winter weather advisory for much of the area, with the exception of Chicagoland’s far southern tier counties. The early morning forecast guidance continues to support a period of strongly forced ascent right across northern IL into northwestern IN as a quick moving clipper system shifts across the area tonight. The combination of the strongly forced ascent and favorably deep dendritic growth zone will support an efficient high ratio type snow up to 20:1. Therefore, it appears snow amounts could end up in the 2 to 5 inch range, with the highest amounts looking to be roughly from the Rockford area, east-southeastward into parts of the Chicago metro area and into northwestern Indiana.

The concern for lake effect snow continuing to accumulate in parts of Lake and Porter counties Indiana on Sunday lead us to issue a winter storm watch for these counties. This was done as we would like to get a closer look at all of the latest hires guidance before making a decision on an advisory or warning for this area. If the lake effect snow materializes, travel impacts would likely be higher and persist longer here, likely through much of the day Sunday. Total snow accumulations as a result could exceed 6 inches in some parts of Lake and Porter counties in Indiana.

Weather Radar shows precipitation observed as snow flurries dissipating, moving from southeast Wisconsin into McHenry County and Lake County at 10:20 a.m. Otherwise Weather Radar in northeast Illinois was clear.
