Reflectivity, UH>25

Dew Points

Good 60-65, great at 65, real great at >= 70

Surface-Based CAPE

0-3km AGL CAPE

Mixed-Layer CAPE

> 1000 is pretty solid, 2000-3000 is better, 4000+ is extreme instability

700mb Temperature

Cap: 10-12c good, temps reaching > 12c considered pretty strong capping

500mb Winds

W or SW: good at 30-35, great when 40-60, over 60 storms may be too fast

850mb Winds

S or SE: 30 kts or higher for tornadoes, big tornadoes when >= 40 kts

0-1km SRH

Anything over 100m2/s2 is considered favorable for tornadic supercells

0-6km Shear

Good >= 35kts, strong when > 40kts and big tornadoes when >=50kts

Supercell Composite Parameter

Significant Tornado Parameter

LCL

1000-1500m range tend to work best for pictures but anything under 1000m favors tornadoes, over 2000 tornadoes unlikely.

On a mission to find the Mother of all Mothership Supercells! We frequently chase around Texas, Oklahoma, Kansas, Colorado and New Mexico during storm season. If a storm blows up, great! Although, just exploring and taking pictures is fun enough!

During a storm chase, we live tweet and post to Facebook!

Who knows what the next storm season will bring, so saddle-up buckaroos and let's ride!
