Meteorological synopsis
On October 5, 2010, a strong area of low pressure situated off the coast of California produced a southerly flow of warm, moist air into Arizona. Clear skies throughout the day allowed for significant instability, resulting in scattered severe thunderstorms during the evening hours. These storms produced widespread damaging hail, ranging up to 2.75 in (7.0 cm) in diameter, and hurricane-force wind gusts of 86 mph (138 km/h). In Phoenix, 2 in (5.1 cm) hail caused considerable damage to structures.
