Thunderstorm

Monsoon thunderstorm of 19 July 2003 viewed from my study. Native plants love this! The cacti include Opuntia englemannii, O. fulgida, and Ferocactus wislizenii.

Once Per Decade Snowstorm

This is my front yard viewed from my study window after the rare snowstorm of 30 Jan 2002. Compare with the thunderstorm viewed from the same location.

Cacti in Evening Storm

Illumination only by lightning gives the desert a blue cast.

Mammatus Clouds

Cumulonimbus mammatus clouds showing strong convection... sometimes the stuff of tornados.

Monsoon Sunset

Monsoon thunderstorms often dissipate after sunset, producing spectacular cloud formations we seldom see the rest of the year.

Approaching Anvil

Thunderhead approaching from the east. Dry air ahead of the storm critically defines the cloud shape against a deep blue sky.

Updrafts

Nice thunderhead development by strong updrafts.
