ROCKFORD, Ill. (WIFR) – There has been a pretty significant cut off in cloud cover. To our southeast, there has been dense clouds, while most of us across the stateline have enjoyed a nice sun filled Sunday. Any clouds that were in the area today will clear out overnight as our winds finally calm down. This will allow for some patchy fog to form by the morning especially in low lying areas. Lows tonight are in the middle to upper 50s.
