I watched this tornado from just north of Roodhouse, IL, beginning around 2:15 p.m., looking to the west-northwest. This tornado continued to the northeast, causing significant damage in Manchester, IL. You can see video of the tornado here.
This was the second of two short-lived tornadoes that occurred near Hawk Point, MO around 7:30 p.m. You can see video of this tornado here.
This tornado began as a stout stovepipe and evolved into a multiple vortex structure. It was on the ground for 20 minutes, as it moved slowly, about 20-25 mph, toward the east-northeast. It mostly stayed in open or wooded country, blowing down a lot of trees but causing very little structural damage as it missed most of the farm buildings in the area. The middle picture above contrasts the tornado as it appeared early in its life to how it appeared when a bright flash of lightning briefly front-lit it.
This rather large but weak tornado touched down a little west of Red Bud (video capture). The storm also produced golfball sized hail.
I wasn't sure this was a tornado at first, but other chasers and spotters who were closer confirmed that it was. (The pictures above are video captures.) You can see a truncated lowering above the dust swirl. Later the same day, I saw a much stronger (EF2) and more long-lasting tornado from another storm near Effingham, but was unable to photograph it as the tornado dropped while I was driving through town.
This rather poor video capture was the only picture I got of this tornado near Cordell, OK. The tornado dropped just as I was driving through the town. Do you see a pattern here?
This picture was taken during the early stages of a F1 tornado that destroyed a bowling alley and damaged several houses and a church in Evansville, IL two days before Christmas. It was my first tornado observed while storm chasing. In one location, the tornado downed several large trees while leaving Christmas decorations on a nearby fence untouched. The tornado occurred with an HP supercell embedded in a squall line.
This brief and weak tornado crossed U.S. 65 just south of Carrolton, MO (video capture). It only lasted for a minute or so. A tornado warning had been issued a few minutes earlier based on radar indication of rotation in this area.
This storm produced tornadoes, gustnadoes, and some vortices that may have fallen somewhere in between. I thought this may have been a gustnado at first, but the facts that 1) it persisted for at least 7 minutes and maybe more like 10 (the two video captures above are about 3-4 minutes apart), and 2) there did appear to be some rotation in the clouds above it led me to classify it as a weak tornadic circulation instead.
Like the one above near Lincoln, this tornado just southeast of the "Big I" freeway interchange on the southeast side of the Quad Cities had no condensation funnel. But the clouds were rotating strongly above the dust swirl (you can see this by looking at the relative positions of the lowered clouds in the front and back above the dust swirl), so what was going on at ground level was clearly tied to rotation in the clouds above. This seems to have formed as the leading edge of a bow echo interacted with an outflow boundary from another storm to its northeast.
