Thanks to frequent blog contributor Dave Skrzyniarz for sending these shots of Tuesday evening's developing thunderstorms as viewed from the Pilsen area.

Thanks to Quentin Calder who sent us these great shots of the thunderstorms that developed over the south sections of the metro area Tuesday evening.

Thanks to Mike Ingram of Donovan, Illinois for these shots taken as thunderstorms swept the area Monday afternoon.

Thanks to Harry Quiroz for sharing this shot of the first round of thunderstorms that hit the southern portions of the Chicago area Sunday night.

Thanks to Mary King of Lisle for passing along these shots of the threatening mammatus clouds that preceded this morning's thunderstorms there. The heavy thunderstorms unfortunately washed out the scheduled Memorial Day parade there.

Thanks for the shots Jim!

Anson Mount sent us this great shot from high above the clouds. HE tells us:

A fellow pilot of mine shot this today near Quincy this afternoon from 37000 feet. Thus cell topped out at 42000!

Thanks for sharing the shot Anson!

Skip Talbot sent us this amazing shot taken on a storm chase in South Dakota. Skip tells us:

While storm chasing north central South Dakota on May 22, I witnessed an absolutely
incredible display of nature's beauty and force.  We tracked a cumulus  field north of Perry, SD that erupted from towering cumulus into a mature supercell in only a half hour.  After several cycles of the mesocyclone, the storm put down several tornadoes including a very powerful EF4.  Attached is a picture of this wedge tornado.  Although out of the path of this tornado, we were still close enough to hear the thunderous roar and have our ears start popping.

The structure on the parent supercell was remarkable as well as it maintained a classic supercell mode through most of its life before finally gusting out as a high precipitation supercell.  Here is video from the chase, which you may also find interesting.  I've built a camera enclosure on the roof of my van with pan and tilt servo motors and programmed custom software  that drives it via my laptop.  This allows me to record the entire chase from any angle.  The video I've linked to is three hours of chasing compressed into ten minutes, from the birth of the storm as towering cumulus to its death as an HP supercell, and several tornadoes in between.



SkipTalbot -- May 25, 2010 -- This is time lapsed footage of an entire storm chase through north central South Dakota on May 22, 2010. The video starts with the storm still in the towering cumulus stage and ends with the storm gusting out as an outflow dominant high precipitation supercell, with several tornadoes including a violent wedge in between:

Thanks to Dave Skrzyniarz for passing along this great shot taken earler this afternoon showing the  development stage of the thunderstorms currently hammering the western and northwest suburbs.
