CSU-CHILL Casebook: 29 August, 2002

During the evening hours of 28 August 2002 (29 August on UTC), a supercell thunderstorm developed approximately 80 km north-northeast of the CHILL radar. Severe weather spotters observed a tornado near the town of Burns, WY around 0136 UTC. A hook echo was present in the low elevation angle reflectivity field at this time. The associated mesocyclone pattern was visible in the radial velocities. (See the VCHILL link below). The storm subsequently moved southward into Colorado and lost its supercell characteristics.

-Numerous thunderstorms developed along a boundary layer radial velocity shear line that was located from just southeast of Greeley, to near Denver International Airport, to the southeast suburbs of Denver.  Shortly after 2100 UTC several non-supercell tornadoes developed along the shear line near where E-470 curves around the southeast portion of the greater Denver area.  (Due to the approximately 90 km range to this area, the tornadic circulations cannot be resovled in the CHILL data.)  As the afternoon continued, a north-south squall line developed just east of Greeley.
