The southwestern United States is experiencing a period of active weather with multiple regions under weather advisories. In Arizona, the National Weather Service (NWS) has issued several special weather statements for areas including Casa Grande, Arizona City, Sacaton, Coolidge, Blackwater, Mesa, Scottsdale, and Fountain Hills until 7:30 PM MST and 8:15 PM MST. These advisories warn of strong thunderstorms, blowing dust with visibility around 1 mile, and localized heavy rainfall. A moisture surge from the south is expected to bring higher chances for showers and thunderstorms, with potential hazards including flash flooding, large hail, and strong winds. Meanwhile, in Colorado, a cold front is moving through eastern parts of the state, bringing cooler temperatures and scattered thunderstorms, some of which may become severe with large hail and severe wind gusts. Oklahoma is also experiencing scattered showers and thunderstorms, with a few storms expected to become strong to severe, posing risks of damaging winds and large hail.
