Analysis of the Severe Thunderstorm Outbreak in Southern Kansas on May 7, 2002

On May 7, 2002, southern Kansas experienced a significant outbreak of severe thunderstorms, driven by favorable synoptic, thermodynamic, and shear conditions. This study presents a detailed analysis of the meteorological factors leading to the development of large supercell thunderstorms that produced destructive hail, high winds, and tornadoes. Key elements include a southern trough's influence, high CAPE values, and significant shear profiles. This investigation utilizes radar imagery, surface analysis, and sounding data to illustrate the dynamics of this severe weather event.

  1. Kansas Severe Thunderstorm OutbreakMay 7, 2002 Christopher Medjber Meteorology 503 Department of Geosciences SFSU

  2. Severe Thunderstorm Outbreak On May 7, 2002 large supercell thunderstorms hit southern Kansas.Here we will present the analysis of the synoptic, thermodynamic, and shear environments that lead to this deadly weather activity.

  3. 500 mb Chart for May 7, 2002 -Upper level trough moving into the western-half of the U.S. -Winds aloft out of the SW are nearly pendicular to winds from Gulf

  4. Surface Analysis for May 7, 2002 -Low pressure system in SW Colorado -Warm front over the Kansas -Cold front in New Mexico -High dewpoints over southern plains -- favorable conditions for buoyant updrafts

  5. KOUN sounding for 00Z -Favorable for severe weather -CAPE: 4161 J/kg -CINH: -1 J/kg -Veering winds with height (hook hodograph) -0-6 km Shear: 49 kts -0-3 km Helicity: m^2/s^2

  6. KTOP sounding for 00Z -Not favorable for severe weather -CAPE: 8 J/kg -CINH: -747 J/kg -Veering winds with height (hook hodograph) -0-6 km Shear: 69 kts -0-3 km Helicity: 690 m^2/s^2

  7. 0-3 km Storm Relative Helicity for May 7, 2002 -Favorable low level shear environment

  8. Visible Satellite Imagery -May 7, 2002 2145Z -May 7, 2002 2315Z Developing Thunderstorm with Overshooting Cloud-top Anvils

  9. Radar Imagery Radar for May 7, 2002 6:37 pm ET Radar for May 7, 2002 7:07 pm ET Splitting Supercell with the left-mover weakening and the right-mover intensifying developing a hook echo

  10. SPC Storm Watches and Warnings for the afternoon of May 7, 2002

  11. SPC Storm Reports for May 7, 2002

  12. Findings -Found favorable synoptic, thermodynamic, and shear environments for supercell thunderstorm activity -In that environment supercell thunderstorms did develop in southern Kansas producing large hail, high winds, and tornadoes
