August 23rd, 2007 Colorado Supercells
Last Updated on Monday, 04 January 2010 21:36 Written by Roger Hill
August 23rd featured decent shear with upslope surface winds in Colorado and 35 knots mid level flow. My plan was to play the Palmer Divide and then follow storms as the built southeast. Morning stratus hindered surface heating. Cells developed in a cool surface environment where intense shear was coupled with good moisture but limited instability. Two supercells formed that I chased, both producing large hail. The first supercell was also tornado warned.

Supercell with strong rotation in a cool and stable surface environment. The core was loaded with 2" diameter hail. |
Notice the tail cloud feeding into the low level meso tucked behind the wet RFD (looking northwest). The storm was tornado warned at this time. |
Closer shot of the tail cloud now wrapping in rain. |
Hail nearly golfball size. |
The hail was between 4-10" deep! |
Melting quickly here, but still quarter sized. |
