Highlights

- The NWS Phoenix forecast office has corroborated the pattern shift independently.
Phoenix will reach a high of 103 degrees Wednesday before cooling to 100 by Saturday, as tropical moisture moves across Arizona and keeps storm chances in the forecast through the weekend, FOX 10 meteorologist Krystal Ortiz reported Wednesday afternoon.
The weekend cooldown comes with a trade-off. AZFamily reported that Tropical Storm Marie is among the systems pushing additional rain chances into the state. A separate AZFamily report from Tuesday noted a developing tropical system was already boosting storm probabilities across Arizona ahead of the weekend pattern shift.
The NWS Forecast Office in Phoenix has independently tracked the same moisture-driven pattern. The Zone Area Forecast for Scottsdale and Paradise Valley shows partly sunny skies with a slight chance of showers and thunderstorms, highs ranging from 97 to 101, and south winds of 5 to 15 mph.
The NWS Scottsdale/Paradise Valley zone forecast is the most actionable number for local readers planning outdoor events this weekend.
