NWS Forecast Office Phoenix, AZ

The potential for a considerable amount of rainfall across a portion of the region exists late next week into the following weekend. Long-range model guidance indicates that abundant moisture from the remnants of a tropical system could be pulled into the Southwest US during the 6-10 day timeframe, and this possibility is reflected in the CPC 6-10 day outlook with 50-70% probabilities of above normal precipitation across much of the area. However, there are many uncertainties, such as the magnitude, exact placement, and timing of rainfall. Stay tuned for updates as this forecast evolves.

Above normal temperatures will continue today with lower desert highs reaching the upper 90s to 100 degrees. A cold front will move through on Saturday morning knocking temperatures back below normal this weekend. HeatRisk will continue to be in the Minor category through early next week.
