06/15/2002 - The June 11, 2002 bowing MCS event produced a few weak tornadoes and a numerous damaging winds reports over parts of west central through south-central Illinois. We conducted a damage survey over this area. Tornadoes (F0 damage) occurred over Rockport Illinois (western Pike county IL) damaging the town's Post Office and 4-5 miles northwest of Vandalia and 2 miles east of Vandalia Illinois in Fayette county.
The Damage Survey Page will be updated shortly with this latest info.

Our staff completed a number of preprints for the 21st Conf. on Severe Local Storms. Check below (Recent publications) for the latest papers produced by Fred Glass, Ron Przybylinski, Gary Schmocker, and Mark Britt from WFO St. Louis. Ron also worked with Brad Ketcham at WFO Lincoln IL on the 29 June 1998 Quasi-Linear Convective System (QLCS) event across north-central and central Illinois and also with Dr. Nolan Atkins at Lyndon State College in Vermont with the 27 May 2000 QLCS over the Mid-Mississippi Valley Region.

05/17/2002 - Since April 21, 2002 WFO St. Louis county warning area has experienced three supercell tornadic events and four non-supercell tornadic events. Except for one supercell episode, all of the events have spawned weak tornadoes, hail of various sizes (up to 2 inches) and damaging winds. We have conducted field damage surveys in six of the seven events. In one of the supercell cases, 6 tornadoes appeared to form along the leading edge of the storm's southern flank (rear flank downdraft). In two of the four non-supercell cases, a low-level boundary appeared to have intersected the developing bow echo. Strong circulations occurred at or near this intersection spawning tornadoes. The other two non-supercell cases were very challenging where tornadoes occurred at or just north of the apex of the developing bow. Check out Storm Damage Survey or Recent Events links for damage survey information. More information on these recent events will be shown on these web pages in Science News.
