I've included five GR3 screen captures from this year below.
(1) 5/19/10 - central Oklahoma. This shot shows both tornadic supercells, including the southern one that produced the now infamous Wurman convergence.
(2) 5/22/10 - Bowdle, South Dakota.
(3) 6/7/10 - The two supercells from the Torrington, WY-Scottsbluff, NE chase.
(4) 6/17/10 - The Albert Lea tornado, probably near Armstong, MN at this point.
(5) 6/21/10 - A nice, lone supercell in western Illinois.
