8-19-09 HP Supercells - Sangamon & Macon County,IL

Storm Reports
http://www.spc.noaa.gov/climo/reports/090819_rpts.html

During mid-day of August 19th, a line of embedded HP supercells broke out across far western Illinois. Many of these produced tornadoes as they progressed throughout all of Central Illinois, flattening corn fields, damaging homes ect. It was a dangerous day for those chasing or stuck out in it due to the tornadoes being heavily rainwrapped. Unless you had good knowledge of radar and storm structure, heading out into these storms would of been potential suicide. I positioned myself in eastern Sangamon County to intercept the Loami cell, which was already producing damage. Moving in on the southeastern portion of the circulation I noticed a Tornado peaking out of the rainshaft to my northwest. The damage I discovered was taken August 20th, about 4 miles west of Mt. Pulaski Illinois.

8-16-09 Shelf Cloud over Long Grove Cemetery - Macon County,IL

I have been after "gravestorm" shots like these since I started chasing...

7-28-09 Arcus Cloud on Outflow Boundary - Macon County,IL

7-24-09 , 6-27-09, 6-24-09 - Macon County,IL

6-21-09 Mini Supercell - Macon County Illinois

As instability increased north of a nearly stationary warm front, a lone Mini Supercell broke out in far eastern Sangamon County before tracking southeast through southwestern Macon County. Just outside of Niantic I would intercept at peak, as a persistant Wall Cloud formed shortly before the storm became tornado warned. As far as I know I was the only chaser on this cell at it's peak...

6-19-09 Supercell & Squalls - Macon, Logan, and Dewitt Counties.

During this moderate risk day, three seperate waves of storms moved through Central Illinois. Supercells broke out in the mid-afternoon hours to kick off the first round... As one became svr warned in McLean County, I chose to hang back and wait for additional supercell development to the south of this cell. Sitting near Kenney Illinois watching a nice base, the next supercell began to form... This would go on to be the storm of the day, with a Tornado reported near the IL/IN border. The next wave would bring a svr warned squall line through most of Illinois, causing wind damage in many locations. To finish off the day, a Cold Front creeping in produced an ominous Shelf Cloud near Latham Illinois.

6-2-09 Shelf Cloud with leading edge circulations - Macon & Dewitt County,IL

6-1-09 Svr Warned Complex - San Jose, Illinois

5-30-09 Supercells - Central, IL

Several supercells broke out across Illinois during mid-afternoon...I intercepted the big one of the day near western Douglas County, then headed back west to Macon and Christian Counties to intercept another supercell sliding southeast.

5-26-09 Mini Supercell - Western Macon County,IL

5-15-09 Tornadic Supercell - Northwest Macon County,IL

With a warm front lifting north through East Central MO & Central Illinois, a large complex formed in Eastern MO before pushing east into Central IL. This storm had tornado warnings throughout most of it's life, and seemed to reach it's peak over West Central IL. Had the most colorful structure I have ever seen since I started chasing, along with a wicked Inflow Tail. The last image is of a rotating Wall Cloud with slight inflow on the line moving in behind the initial supercell.
