Arizona – Rain chances are expected to increase across parts of Arizona during the January 7–13 period, according to the latest federal weather outlook, signaling a shift toward a wetter pattern across the Southwest.
According to the National Weather Service Climate Prediction Center, Arizona is included in a region forecast for near- to above-normal precipitation during the 8–14 day window. In January, this pattern supports periods of rainfall, particularly across central, southern, and western portions of the state as Pacific storm systems move inland.
Much of Arizona falls within the 33–50% probability range for above-normal precipitation, indicating an increased likelihood of multiple rain events rather than a single prolonged storm. Lower desert areas, including the Phoenix and Tucson metro regions, may see intermittent rain, while higher elevations could experience different precipitation types outside the scope of this rain-focused outlook.
Temperature outlooks for the same timeframe indicate near-normal temperatures statewide. This setup favors rain as the dominant precipitation type at lower elevations, while cooler air may briefly follow passing systems.
For commuters, students, and freight operators, increased rain chances may lead to slick roads, reduced visibility, and slower travel during heavier rainfall. Major corridors including Interstate 10, Interstate 17, Interstate 40, U.S. 60, and State Route 87 may be impacted, especially in urban areas and along desert highways prone to runoff.
Even modest rainfall can cause localized flooding in Arizona due to dry soils and desert terrain. Low-water crossings, washes, and normally dry riverbeds may become hazardous during heavier rain.
Forecasters emphasize that 8–14 day outlooks reflect probability trends, not specific rainfall totals or storm timing. Residents are encouraged to monitor daily forecasts and updates from local National Weather Service offices as the period approaches.
No flood watches or rain-related advisories are currently in effect based solely on this outlook, but the signal supports increased awareness for rain-related impacts during the second week of January.
