A Flood Watch has been issued for a majority of Maricopa County, and all of Pinal and Gila Counties. An increase in moisture and atmospheric instability will combine with an incoming weather system to promote scattered thunderstorms. These storms will be capable of producing heavy rainfall from late today through early Sunday morning. Training storms could result in localized heavier rainfall amounts of over two inches.
The increase in moisture and instability combined with an upper level disturbance will continue to result in good chances for thunderstorms and showers across South-Central AZ, and the eastern higher terrain Sunday and Monday. The main impacts from these storms will continue to be localized areas of heavy rainfall, frequent lightning, strong winds and dust. The timing of these storms are likely to remain in the evening to overnight periods.
Temperatures will continue to remain several degrees above normal today as highs exceeding 110 degrees across much of the lower desert communities. Starting on Sunday and continuing through the first half of next week, temperatures are expected to cooldown to near to slightly below normal levels.
