PHOENIX -- The weekend will present a transition in our weather pattern from warm and dry to cooler and slightly wetter, with a slight chance for precipitation by early next week.

We’re going to see desert high temperatures drop from the 80-degree range to the low 70s, which is about average for this time of year.

The trough of low pressure that will trigger the changes is going to be very widespread, essentially encompassing most of the country.

Along that flow, an upper-level low will begin forming over the weekend and embed itself over the Southwest into early next week.

As weather disturbances move around that low-pressure system, we’ll see a few opportunities for mainly light rain/snow shower activity.

But for the weekend, no worries if you have outdoor activities planned around the Valley. There’s no chance for rain, and even though temperatures are coming down into the 70s, that’s still a bit above normal.
