<=== One of my favorite supercell images is near Grand Island, Nebraska on June 12, 1993, looking west.    This "flying saucer" storm produced a brief rope-like tornado, and large hail as it drifted southeast.

<=== Here's another "spaceship" supercell, over northeast Barber County, Kansas on June 5, 2004.    This awesome storm was a surprise structure-wise as it moved due south, producing large hail.

061592sprcl6(c)_sml.jpg (103633 bytes) <=== This ominous heavy-precipitation (HP) supercell near Osborne, Kansas on June 15, 1992 produced softball-size hail and several rain-wrapped tornadoes.  The photo is looking west. 061505ictsprcl1(c)_sml.jpg (101645 bytes) <=== I caught this supercell storm approaching northwest Wichita after dark on June 15, 2005.  The structure was illuminated by cloud-to-cloud lightning during this 2 second exposure.

<=== Here's a heavy-precipitation (HP) supercell moving southeast over southwest Oklahoma (Harmon County) on April 18, 1992.  The view is northwest.  This storm produced baseball-size hail, but no tornadoes.

<=== This is the same Oklahoma storm, but looking west-southwest.  The sun's backlighting illuminated the rain-filled area of the storm, with laminar striations marking the advancing outflow.
052691oksprcl1(c)_sml.jpg (100185 bytes) <=== The massive striated supercell seen here produced a tornado east of Woodward, Oklahoma on May 26, 1991. Dust and a weak gustnado are visible at left along the storm's gust front, looking west. 050593okpnhlsprcl&tor1(c)_sml.jpg (92742 bytes) <=== This supercell updraft and mesocyclone on May 5, 1993 was producing an F3 tornado (visible at lower right) east of Guymon, Oklahoma. View is toward the southwest.

<=== A road leads to the mesocyclone looking west over southwest Pratt County, Kansas on March 17, 1992, not far from my childhood home. This rotating supercell circulation produced large hail, but no tornadoes.

<=== This large heavy-precipitation (HP) supercell on April 18, 2002 was near Canton (foreground) in central Kansas.   Looking west, this storm produced a couple brief weak tornadoes, and some large hail.

<=== This barrel-like supercell mesocyclone loomed overhead at Long Island in northwest Kansas on June 3, 1999 as golf ball size fell around me.  Although this storm spawned no tornadoes, an earlier supercell produced a long-lived tornado near Almena, Kansas. 060399sprcl6(c)_sml.jpg (97406 bytes) <=== This is the same supercell seen in the previous photo, looking west later on, at a greater distance.  With the low-level laminar striations, a sunlit tower, and the sun setting behind, it was a truly awe-inspiring sight.
