Significant weather changes are expected in Arizona this week as remnants of Hurricane Priscilla lead to increased rainfall across the region. A Flood Watch is in effect for northern Arizona, particularly affecting areas such as Flagstaff, from Thursday afternoon through Saturday.
Weather Forecast Overview
Temperatures in Phoenix are forecasted to reach highs in the upper 90s, potentially hitting the 100-degree mark today. If attained, this would mark the last day of triple-digit temperatures for some time.
Effects of Tropical Moisture
Prior to Priscilla’s arrival, tropical moisture is forecasted to bring scattered showers to eastern Arizona and the higher terrain east of Phoenix this afternoon. As Priscilla, now weakening west of the Baja Peninsula, continues to dissipate, additional moisture will flow into the Valley by Thursday night.
Friday’s Rainfall Chances
From Thursday night into Friday, moisture from Priscilla will combine with a disturbance moving in from the west. This interaction is likely to produce rain and possible thunderstorms throughout the Valley, which could complicate Friday commutes, especially in the evening. For this reason, Friday has been designated as one of the three First Alert Weather Days.
Weekend Forecast and Flood Risks
Forecasts indicate that rain may persist into Saturday. While rainfall won’t be uniform across the Valley, the risk of flash flooding remains a concern. Saturday and Sunday have also been marked as First Alert days due to the potential for significant rainfall.
- High temperatures on Friday are expected to range from the low to mid-90s.
- Rainfall totals from Thursday night through Sunday may reach 1 to 1.5 inches in the Valley.
- Higher elevations could see rainfall exceeding 2 inches.
- Even on Sunday, there’s a 40% chance of rainfall in the Valley with high temperatures in the 80s.
Looking Ahead
As we transition into the early part of next week, there’s also a 20% chance of rain on Monday and Tuesday. Residents are urged to stay updated on weather conditions and prepare for possible flooding risks as the remnants of Priscilla continue to impact the area.
