Several waves of severe thunderstorms moved westward across the central and eastern portions of Maricopa County. Upper level winds were stronger than usual, and copious moisture combined with warm temperatures allowed storms to redevelop well into the night. Winds over 80 mph were noted in parts of Phoenix and Tempe. Nearly continuous lightning was also observed during the peak of the activity. Fortunately, no fatalities were associated with these severe storms.
