Storm Postmortem: Major severe weather outbreak Tuesday over southern Arizona

Yesterday was about as active as the Monsoon gets in the Sonoran Desert. Above is time-lapse video of a severe thunderstorm near Vail. Notice the mid-level rotation within the storm. Thanks to Trey Greenwood for sharing this amazing footage.

A mid-level disturbance cruised in from the east Tuesday, combining with ample moisture and daytime heating to fuel widespread storms. Two things made yesterday’s event very unique for our part of the country. For starters, the majority of the severe weather reports were large hail. Hailstones typically melt fast while descending into the desert, only ending up as pea-size. To see quarter to ping pong ball-sized hail is a rarity.

Later in the evening, a rotating wall cloud near Huachuca City prompted the National Weather Service to issue its first Tornado Warning since September 10th, 2011. This Tornado Warning was only out for 10 minutes (roughly 7:35 – 7:45 PM) & there was no actual tornado touchdown. Keep in mind that Arizona usually sees 4 tornadoes per year, many of which occur in the northern part of the state.
