More October rain expected in Phoenix area this weekend

PHOENIX — One of the wettest Octobers in Phoenix history is about to get wetter.

There’s a 50 percent chance for showers Saturday night, with the likelihood going up to 60 percent Sunday, according to the National Weather Service.

Sunday’s temperature is expected to top out at 79 degrees before falling to 60 or lower overnight.

The rain will bring a slight risk for flash flooding.

There’s a 10 percent chance for rainfall Monday morning, and skies should be mostly clear by that evening.

Valley temperatures are expected to remain below normal in the coming days, with more rain possible later in the week.

The expected activity this weekend comes on the heels a dousing by the remnants of former Hurricane Rosa, which caused flooding and dangerous road conditions throughout the state.

On Tuesday, Phoenix was drenched with 2.36 inches of rain, the most ever for an October day.

It’s already been the third-wettest October ever in Phoenix.

And if you are thinking about heading north in the coming days, be aware that the area could see the first snowfall of the season.

Megan Taylor of the National Weather Service in Flagstaff told KTAR News 92.3 FM on Friday that a cold system was moving south into the area.

It will bring winds, cooler temperatures and a chance for thunderstorms, “along with potentially some snow up in the high terrain” above 8,000 or 9,000 feet Sunday and Monday.

She also said temperatures in the region could fall below freezing for the first time this fall.
