Strong storm coming this weekend

A strong Pacific storm could bring one to three inches of rain to Prescott this weekend, forecasters say.

Some localized areas could see even heavier amounts, said Clair Ketchum, a meteorologist with the National Weather Service office in Flagstaff.

"The moisture looks to be pretty deep," he said. "We're going to have a lot of good action going on."

Snow levels probably will be slightly above Prescott's elevation, at about 5,800-6,000 feet in this region, Ketchum said. The Yavapai County mountains at that elevation could see 4-8 inches of snow on the ground, but the northern Arizona mountains above 8,000 feet might get even two feet.

Heavy rain should start here tonight and continue through Sunday, he said.

The Weather Service is warning people near washes and streams south of the Mogollon Rim to stay alert for updates because of the potential for flooding.

The Weather Service also is forecasting strong winds with this storm, gusting as fast as 45 mph by Sunday evening.

The agency is predicting a 70-percent chance of rain in Prescott tonight, wind and rain for sure on Sunday, then rain and possibly snow Sunday night.

A cold front should arrive Sunday night and Monday but by then the storm won't carry much precipitation if any, the Weather Service said.

Unsettled weather could continue through Thursday, with a 30-percent chance of rain and snow Monday, 20-percent chance of rain and snow Monday night, 10-percent chance of rain Tuesday, 30-percent chance of rain and snow Wednesday, 20-percent chance of snow Wednesday night, and 10-percent chance of rain and snow Thursday.

Prescott's official Sundog measuring site on the northeast side of the city recorded only one-hundredth of an inch of precipitation during the 24 hours ending at 7 a.m. Friday, but Prescott Valley got a bit of snow and some other areas saw good precipitation.

Bagdad recorded 0.81 inches of rain and Sedona reported 0.60 inches.

The rain across northern Arizona with that weak system was spotty, Ketchum said.
