Temperature Outlook

A more active weather period is expected to start later today as increasing moisture and instability, combined with an upper-level disturbance, will result in a greater coverage of showers and storms. The greatest coverage of activity is currently forecast across south-central AZ, and the eastern higher terrain. All thunderstorm hazards are on the table including heavy rainfall leading to localized flash flooding, strong to severe wind gusts, areas of blowing dust, frequent lightning, and even some small hail.

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.

Strong high pressure over the Southwest will lead to abnormally hot temperatures through today with temperatures 5-7°F above normal. This will result in Major to Extreme HeatRisk across much of the lower deserts. The Extreme Heat Warning remains in effect through tonight for much of the area.

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.
