Overview

• Rain chances increase statewide starting mid to late week, with the highest likelihood for widespread and heavier showers Friday and Saturday.
• Moisture levels could reach about 200% of normal, raising the potential for multiple rounds of precipitation through the weekend and possibly into early next week.
• Some locations in central and eastern Arizona could receive 1 to 2 inches of rain with higher totals in foothills and mountains, and there is roughly a 10% chance of amounts exceeding 2 inches.
• Washes and small creeks may start flowing, creating a risk for localized flooding, with southeast California and western Arizona likely seeing the first showers and northern Arizona highlighted for heavy rain potential.
• A brief heat spike into the mid to upper 90s—near 100°F in spots—precedes the pattern before highs drop into the 80s as the wetter, cooler air arrives.
