Arizona residents are bracing for a weather shift this week as a cut-off low system is expected to bring a mix of snow and rain to the state.
The midweek storm, set to hit Arizona between Wednesday and Thursday, has meteorologists on high alert as it moves across the region, potentially causing disruptions to travel and daily activities. Here’s what you need to know about the approaching weather event.
What is a Cut-Off Low?
A “cut-off low” is a weather phenomenon that occurs when a low-pressure system detaches from the jet stream and becomes isolated from the prevailing air currents. This creates a more stationary system, which can lead to prolonged periods of precipitation in a specific area. Unlike typical storm systems that move quickly across the region, a cut-off low can bring days of rain and snow, often resulting in more unpredictable weather patterns.
The current cut-off low impacting Arizona is expected to bring a combination of snow in higher elevations and rain to lower-lying areas, which could lead to hazardous conditions, especially on the roads.
Snow in the High Country
As the cut-off low moves into Arizona, the state’s mountainous regions will likely see significant snowfall. Areas like Flagstaff, Prescott, and the Mogollon Rim are expected to receive several inches of snow, with some spots potentially getting up to a foot of snow by the end of the storm. This could create challenging travel conditions, especially along highways like I-17 and I-40, which are prone to winter weather hazards.
The Arizona Department of Transportation (ADOT) has issued warnings for drivers heading into these mountainous areas to be prepared for slick roads, reduced visibility, and possible closures. Drivers should carry emergency supplies, including chains for tires, in case of road closures due to heavy snow accumulation.
Rain in the Valley
While Arizona’s high country faces snow, the state’s lower elevations, including the Phoenix metropolitan area and Tucson, are expected to experience rain. The valley cities will likely see periods of moderate to heavy rainfall, which could lead to localized flooding in areas with poor drainage systems.
Phoenix, in particular, is forecast to receive up to 0.5 inches of rain, and the storm could bring gusty winds as well. The storm’s impact on urban areas could lead to temporary disruptions, especially during peak commuting hours.

While Arizona is known for its dry climate, it’s not immune to flooding, especially during intense rainstorms. The midweek storm is expected to bring a significant amount of rain over a short period, which increases the potential for flash flooding in certain areas.
The National Weather Service (NWS) has issued flood watches for parts of southern and central Arizona, warning that small streams and washes could quickly swell due to the rain. People in flood-prone areas are advised to stay alert and avoid driving through flooded roadways. Additionally, residents in low-lying areas should be prepared for the possibility of water inundating their properties.
Timing of the Storm
The cut-off low will begin affecting Arizona on Wednesday, with rain and snow starting in the northern parts of the state in the early afternoon. The system will move southward throughout the day, bringing snow to the higher elevations and rain to the desert areas by the evening. The storm will continue to linger over the state through Thursday, with conditions expected to begin clearing by Friday morning.
What You Can Do to Prepare
As the storm approaches, there are a few steps you can take to stay safe and prepared:
- Check Weather Updates: Stay informed by checking local forecasts and alerts from the National Weather Service. This will help you monitor changes in the weather as the storm progresses.
- Drive Cautiously: If you’re traveling through snow-prone or rain-affected areas, slow down and be mindful of slick roads. Carry emergency supplies, and keep a fully charged phone in case you need assistance.
- Be Flood Aware: If you live in a flood-prone area, know your evacuation routes and avoid driving on flooded roads. Stay indoors during heavy rain, and keep an eye on local flood alerts.
- Prepare Your Home: Check that your gutters are clean and your drainage systems are functioning properly to avoid flooding in your yard or driveway. If necessary, bring outdoor items inside to avoid wind damage.
Conclusion
Arizona’s midweek weather is shaping up to be an unpredictable mix of snow, rain, and possible flooding due to a cut-off low system. While higher elevations will see snow and winter driving challenges, rain is expected to create slick conditions in lower-lying areas.
Residents need to stay informed and prepared for rapidly changing weather, especially if they are traveling in the affected areas. With the right precautions, you can stay safe and make it through this stormy stretch.
