A strong winter storm and its associated cold front rolled through the central Arizona deserts on January 25th, leading to widespread wind damage across much of the greater Phoenix metropolitan area. A line of strong to severe thunderstorms associated with the front generated wind gusts in excess of 60 mph in some locations and the gusty severe winds downed numerous trees, caused damage to roofs and fencing, and in southwest Mesa managed to blow a rooftop air conditioner off of the roof. More than 30,000 utility customers across the Valley lost power at the height of the storm as numerous power poles were snapped or blown over. Several Phoenix area outdoor COVID-19 vaccination sites saw some minor damage to the tents and overall setup from the strong winds, which led to some delays. Rain cooled air associated with the strong storms lowered afternoon temperatures at Phoenix Sky Harbor airport from around 50 degrees to 36 degrees in 25 minutes. Many areas saw pea-sized hail as the storms moved through the Valley. There were no reports of injuries associated with the damaging winds.
