Phoenix Weather: Record Rainfall Meets Incoming Storms

Phoenix Weather: Record Rainfall Meets Incoming Storms

Phoenix residents are experiencing a weather phenomenon as the city's annual rainfall totals have officially surpassed the yearly average. As of November 18, Phoenix Sky Harbor International Airport recorded 7.71 inches of rain – exceeding the historical average of 7.22 inches. This milestone comes as a new weather system approaches, bringing additional showers, cooler temperatures, and potential severe weather to the Valley.

Breaking Rainfall Records

This year's precipitation has been particularly noteworthy, with meteorologists noting that some areas could see an additional 0.75 to 1 inch of rain in the coming days. According to Ryan Worley of the National Weather Service, rainfall distribution will be uneven across the region. "Not everywhere is going to see rain totals in that range," Worley explained, adding that some areas might remain relatively dry while others experience significant downpours.

The storms arrive after an uncharacteristically warm November, with Phoenix experiencing one of its hottest month starts on record. This weather shift brings much-needed relief from the heat, though it also introduces potential hazards.

Severe Weather Threat Includes Hail

While the primary concern is heavy rainfall, residents should also prepare for severe thunderstorms capable of producing hail. The National Weather Service has issued warnings for parts of the West Valley, indicating that damaging winds and large hail could accompany the system. Lightning is expected to be sporadic but poses a risk to those outdoors.

Flooding risks remain relatively low, with meteorologists estimating less than a 5% chance of significant flash flooding. However, localized flooding is possible in low-lying areas and near washes, particularly in regions receiving the heaviest rainfall.

Noticeable Temperature Drop

Perhaps the most welcome aspect of this weather system is the dramatic cooldown. High temperatures will plunge into the high 60s and low 70s – about 10 degrees below average for this time of year. By mid-week, highs are expected to reach only the mid-60s, offering a stark contrast to the unseasonably warm conditions Phoenix experienced earlier in November.

This temperature shift provides relief from the record-breaking heat and signals the transition toward cooler winter weather. The cooler air will also help stabilize the atmosphere, potentially reducing the intensity of any thunderstorms that develop.

What to Expect Moving Forward

Weather experts advise residents to stay updated on the latest forecasts, as storm tracks can shift quickly. Those planning outdoor activities should have backup plans ready, and drivers should exercise caution on wet roads. The rainfall, while disruptive in the short term, is beneficial for the region's water supply and drought conditions.

Phoenix's weather patterns continue to demonstrate the city's climatic diversity, where residents can experience everything from extreme heat to unexpected storms within a single season. This latest system serves as a reminder of the importance of preparedness in the Valley.
