Evening everyone, we just wanted to give you all a quick update and round up of the facts. The Tornado Warning for Stephenson County was allowed to expire around 8:45 pm as the storm quickly showed signs of weakening. The initial warning came out around 8:27 pm. According to the NWS in Quad Cities, the warning was issued solely based on the sheriff report of a tornado near Elroy, IL. At this time there have been no confirmed reports of damage, but if that does change we will be sure to update this post.
It is hard to confirm if there was, in fact, a tornado there or not at this time. Radar scans from the NWS Quad Cities would be scanning around 5,100 ft with the cloud ceiling in Freeport around that time being down around 1,500 ft. Meaning the radar was not scanning the lowest elevations and would not be able to see any low-level rotation if it were there. If we get any updates, we will be sure to update this post!
