I was watching for a while around 2100z, and at that time, a couple did pop up. These were very short lived.
Interestingly, something popped up on 1710 at the same time, and I had audio for about 15 seconds. A YL was giving weather, but no clues as to the city or region were given. This did not sound like anything I have heard on the 1710 station in Chicago.
