Light rain falls in parts of metro Phoenix ahead of monsoon season

Although some drivers across metro Phoenix are seeing sprinkles during their Friday morning commutes, residents shouldn’t expect heavy rain, according to the National Weather Service.

“The setup that we have currently over the region is bringing up a lot of moisture from parts of Mexico and up the Baja Peninsula, so that’s actually setting off these showers that we’re seeing across parts of the region,” NWS meteorologist Ryan Worley told KTAR News 92.3 FM.

However, the raindrops aren’t falling across the Valley evenly. In fact, most areas won’t see any raindrops.

“Most areas are not going to see rain,” Worley said. “Chances are around 10% to 15%, so it’s going to be very hit or miss. You might see what’s known as virga, which is rain that doesn’t reach the ground because it evaporates. So, (we) could see that throughout the day, but, again, most people will not get in on any of the rainfall.”

Virga and light showers continue to linger around the region this morning. You may experience a few drops during your commute around the Phoenix metro, but measurable rain will still be hard to come by with this activity. #azwx pic.twitter.com/NQxtLPvzsJ

Monsoon season officially starts in Arizona on June 15. It runs through Sept. 30.

What are the chances of seeing rain in the Valley this weekend?

There’s also a chance of scattered showers across parts of metro Phoenix over the weekend.

“It looks like we could see a kind of a repeat as we head into Saturday morning, where we see these very isolated showers around,” Worley said. “As we move beyond that, we’ll start to dry out a little bit more. Even the chances beyond today, like into Saturday, will be around 10% to 15% at most.”

Overall, most Phoenicians can safely leave the house without bringing their umbrellas.

“You shouldn’t be expecting to see rain, but you might. It’s going to be very isolated in nature,” Worley said.

The most likely rainfall will be Saturday morning. Despite the moisture, the Valley will remain warm.

“This morning, we were very warm from what we were originally forecasting,” Worley said. “So far, the low at Sky Harbor was 89 degrees, so that’s quite mild for overnight temps, but as we head through the next several days, our high temperatures are not going to be impacted much by this setup.”

In fact, NWS is calling for afternoon highs from around 107 to 110 degrees over the next several days, he explained.

“Unfortunately, even though we are seeing the moisture, it’s not going to help us very much,” Worley said. “It’s still going to be hot.”
