- Tornadoes and Hail in Arizona, October 6, 2010A strong low pressure center over California pushed abundant moisture over Arizona producing widespread thunderstorms with numerous severe storms. Strong vertical wind shear...with helicity in the 400-450 range...also provided an environment for supercell development.
- Flooding and Hail in Arizona, August 10 to 31, 1999Microburst winds and heavy rain developed over much of north Phoenix around 430 pm. As many as 20 power poles were downed by the high winds, and torrential rain near Rose Garden Lane between 19th and 25th avenues.
- Flash Flooding and Heavy Rain in Arizona, July 23 to 25, 2021Deep monsoon moisture over northern Arizona and an area of low pressure moving over the area from the east brought more thunderstorms with heavy rain, flooding, and at least one funnel cloud.
- Flash Flooding and Hail in Arizona, September 10, 2011Increasing moisture interacted with an upper level shortwave trough to produce afternoon showers and thunderstorms. Some of the storms produced heavy rainfall and strong winds.
- Tornado and Flash Flooding in Arizona, November 18 to 19, 2025Between the evening of November 17th and the evening of the 20th, a slow-moving upper-level low pressure system progressed through the Desert Southwest.
- Flash Flooding and Flooding in Arizona, October 11 to 14, 2025An influx of tropical moisture from tropical storms Pricilla and Raymond allowed for deep moisture as well as showers and thunderstorms to form from October 11th through October 14th.
- Tornado and Flash Flooding in Arizona, July 2, 2021Scattered thunderstorms moved west across southeast Arizona. Storms produced flash flooding and a swath of damaging winds across the Tucson Metro area, and a landspout was also observed.
- Hail and Damaging Wind in Arizona, September 7, 2002Power lines reported down on a house in Maricopa.
- Flash Flooding and Hail in Arizona, October 6 to 7, 2015A low pressure system deepened as it moved south along the California coastline. It dug slowly through southeast Arizona for 2 days with good synoptic-scale dynamics, leading to damaging wind, heavy rain, large hail and funnel clouds across the region.
- Flash Flood and Flooding in Arizona, July 5 to 28, 1998A preliminary evacuation of the Supai Campground occurred due to rises in Supai Creek and its tributary Cataract Creek.
- Flash Flood and Damaging Winds in Arizona, August 11, 2015South to southeast flow aloft prevailed over southern Arizona. Thunderstorms developed early with heavy rain and flash flooding near Tucson. Thunderstorms became severe by evening, with damaging winds in Tucson and Safford.
- Hail and Damaging Wind in Arizona, August 17, 2023Scattered thunderstorms developed and moved northwest across southeast Arizona during the afternoon and evening. One storm produced damaging winds and large hail in Marana. A funnel cloud was also observed.
- Tornado and Hail in Arizona, October 18, 2024A strong upper low diving southeastward through southern Nevada and across northern Arizona with instability and upward motion brought widespread showers, thunderstorms, snow, and strong winds.
- Flash Flooding and Damaging Winds in Arizona, July 12, 2021Thunderstorms developed and moved southwest across Pinal, Pima and Santa Cruz counties during the evening hours. One storm produced a funnel cloud near Mt. Wrightston while other storms produced damaging winds and flash flooding in the Tucson Metro area.
- Tornado and Hail in Arizona, September 14, 1999A stationary trough of low pressure centered over Nevada introduced strong westerly vertical shear to northern Arizona. This shear combined with the ever present monsoon moisture to produce numerous reports of severe weather across Yavapai county.
- Flash Flooding in Arizona, July 4, 2012Very moist air of around 1.75 inches of precipitable water contributed to the development of thunderstorms across much of southeast Arizona. Some storms produced very heavy rainfall, primarily in Pima and Pinal Counties. One storm even produced a brief funnel cloud near Tucson.
- Damaging Winds in Arizona, August 7, 2000Public sighting of funnel cloud in Globe.
