Could the Valley see rain this weekend?

PHOENIX — After a stretch of extreme heat, our ridge of high pressure is shifting into the “sweet spot,” bringing a better chance for monsoon storms.

On Saturday, storms will once again be focused mainly across southeastern Arizona. By Saturday evening and into the overnight hours, outflow boundaries from storms near Tucson are expected to kick up blowing dust and move into Pinal County, with the potential to reach parts of the Valley.

A High Pollution Advisory for blowing dust is in effect through 2 a.m. Saturday for Maricopa County and through 11 p.m. Saturday for Pinal County. Air quality may be poor, so anyone with respiratory conditions should limit time outdoors.

On Sunday, another round of storms is expected to develop, with more widespread activity along the Mogollon Rim. Those storms, combined with activity farther south, have a good chance of pushing into the Valley by the evening.

A Level 1 of 5 severe weather risk is in place for the Valley on Sunday. Stronger storms could produce wind gusts of 50 to 60 mph, heavy rainfall, and frequent lightning. If you have evening plans, make sure you have a way to receive weather alerts and be ready to head indoors if storms approach.

If you’re driving and encounter blowing dust, don’t try to drive through it. Pull off the road as far as possible, put your vehicle in park, turn off your lights, and take your foot off the brake. Remember: Pull Aside. Stay Alive.

As storm chances increase, temperatures will gradually trend closer to normal. Highs across the Valley this weekend will top out around 108 to 109 degrees.

An Extreme Heat Warning remains in effect for the Grand Canyon below 4,000 feet through Sunday evening, and for Glen and Marble canyons from Saturday morning through Sunday evening. If a canyon hike is on your weekend plans, it’s a good idea to reconsider because of the dangerous heat.

Monsoon moisture will remain in place through next week, keeping daily storm chances in the forecast and temperatures closer to seasonal averages.
