Arizona’s Monsoon: Simple Explanation of the Weekend Storms

What Is Going On? (ELI5)

Imagine the sky is turning on its big summer sprinkler and fan—that’s what people in Arizona call the monsoon. It’s a season when rainy and windy storms visit. This weekend, the weather is being extra active! A news team from Phoenix (AZFamily) says the monsoon is back, with blowing dust concerns this evening and possible strong-to-severe thunderstorms on Sunday afternoon and evening.

Warnings and Advisories in Effect

Special alerts have been issued to help everyone stay safe:

• Severe Thunderstorm Watch: This is a heads-up that big thunderstorms that could be dangerous might happen. It is for southern Arizona, including Pinal County, until 10 p.m. tonight.
• Blowing Dust Advisory: This is a notice that strong winds may lift dirt into the air and make it hard to see. It is in effect from 6 p.m. to 10 p.m. for Pinal County and the southern parts of Maricopa County (places like Queen Creek are included).

Important: If you are in these areas during those times, expect possible strong winds, dust, and low visibility (the world may look fuzzy and far-away things hard to see).

This Evening’s Weather (Saturday)

Scattered thunderstorms (storms that pop up here and there) will continue across southeastern and north-central Arizona this evening.

These storms might bring:

• Heavy rain (lots of water falling from the sky)
• Strong wind gusts (sudden pushes of air)
• Areas of blowing dust (tiny dirt particles flying around)

The biggest dust trouble is expected to stay in Pinal County, but communities such as Queen Creek could also see reduced visibility. Some of the “outflow winds” (think of them as invisible walls of wind that flow out from a storm) and blowing dust may travel into the Phoenix metro (the big city area) later tonight. However, that will depend on whether those wind boundaries stay strong enough to carry the dust there.

Sunday: A First Alert Day

Sunday is called a First Alert Day—a special label our local weather friends use to say, “Hey, pay extra attention to the weather today!”

• There is a 40% chance of showers (light rain) and thunderstorms developing late in the afternoon and continuing into the evening.
• Blowing dust will again be possible.
• A few storms could become severe, with damaging wind gusts (winds strong enough to break things).
• While many neighborhoods across the Valley (that’s the Phoenix area) may stay dry, some could receive 0.10 to 0.25 inches of rain (a small amount, like a tiny puddle).
• Afternoon high temperatures will reach around 109 degrees Fahrenheit (very hot!).

Important: Even if your street looks dry, a strong storm with dust or wind could appear nearby, so keep an eye on the sky.

Next Week’s Forecast

The active monsoon pattern (the stormy period) keeps going into next week. Here is the simple breakdown:

• Monday: 20% chance of showers and thunderstorms.
• Tuesday and Wednesday: Slight rain chances (very small possibility).
• Late week (Thursday–Saturday): Rain and storm chances are expected to increase again.
• Temperatures:
  • Near 108 degrees through Wednesday.
  • Cooling to about 105 on Thursday.
  • Friday and Saturday could fall to the upper 90s to around 100 degrees (still warm, but a bit better).
