Flood Control District of Maricopa County
Storm Report - July 14-15, 1999
METEOROLOGY
The airmass over Maricopa County on July 14th was unusually moist, with water content above normal for July. This condition was also present the previous 4 or 5 days, but no significant rains took place, though there was rain on the 13th over portions of the County. However, on these previous days there were significant and rather widespread storms over far western Arizona and southeast California due to a stationary disturbance in the upper atmosphere over this area.
A small portion of this disturbance moved across Maricopa County on the 13th, but the main portion remained centered near the Colorado River. The bulk of the upper air disturbance moved into Maricopa County on the 14th. This unseasonably strong disturbance (making the air unstable), coupled with a very moist airmass resulted in our significant rains.
Note: This was a very unusual event. One reason is it occurred during the morning and afternoon hours. Normally we see our action during the evening. For another, the thunderstorms moved in from the southwest, rather than the southeast to northeast. Southwest winds usually result in NO thunderstorms, as higher terrain (such as to our east) is necessary to form the storms.
