Like some people said after chasing yesterday in the plains, it's not easy keeping up with HP supercells moving 50 mph. I intercepted a couple of those today on the southeast fringes of the STL area. Both were TOR-warned, and there were a handful of reports of brief touchdowns with both.
Wall cloud and possible funnel cloud with the first storm:
Note the bridge below the wall cloud. This is the Jefferson Barracks Bridge, the main crossing of the Mississippi on the south side of the St. Louis metro area. This picture was taken looking northwest from the west edge of Columbia, IL. A couple Missouri spotters near the wall cloud reported funnel clouds around this time, and trees were blown down on a house and a garage. This meso reportedly produced brief touchdowns later in the Collinsville and St. Jacob, IL areas. It is very fortunate that it did not do more, as it moved for a long distance over densely-populated areas in the southern and eastern suburbs of St. Louis.
Wall cloud from the second storm over Waterloo, IL:
This picture was taken looking northwest from a couple miles east of Waterloo. Note what may be a funnel just to the right of the wall cloud - I couldn't tell, but wouldn't be surprised, as there were a couple reports a few minutes earlier of a tornado with this storm 4 or 5 miles to the southwest of its location when this photo was taken.
I tried to chase the first storm a little but could not keep up. The second one wrapped up in rain and disappeared very quickly after this picture, and I had to bail to keep ahead of the wet RFD.
I will post a more detailed account of this chase on my Web site when time permits.
