SIERRA VISTA — Ready for some rain?

The National Weather Service says there’s a good chance you will see it this weekend in Cochise County.

A “trough of low pressure” will be moving through Southern Arizona today that is expected to bring valley rain and possibly mountain snow, though the snow level is expected to be “fairly high,” according to the weather service’s Friday afternoon hazardous weather outlook.

Gary Zell, a weather service forecaster in Tucson, said the winter storm coming from the Pacific Ocean will not be as strong as that now being seen in California.

“It doesn’t look like it’s a big one,” Zell said of the forecast Arizona storm.

Southern Arizona, he said, will see the southern edge of that storm as it moves into the United States, and the strength of the California storm should be reduced by the time it reaches Arizona.

The chance of rain in Sierra Vista and Bisbee today is 10 percent during the day and 20 percent at night. On Sunday and Monday during the day, the chance of rain is between 40 to 50 percent.

Temperatures will remain moderate, with highs today in the low 60s and lows in the low 40s in Sierra Vista and Bisbee, the weather service said. Temperatures will get cooler on Sunday and Monday.

Temperatures in Douglas are predicted to be a bit cooler during the day but warmer overnight.

By Tuesday, mostly sunny weather is forecast.

The federal Climate Prediction Center’s three-month outlook for Southern Arizona is for below normal precipitation and above normal temperatures.

The storm this weekend will be the remnants of one now pounding California.

Howling winds, pelting rain and heavy snow pummeled California on Friday, toppling trees, flipping big rigs, cutting power to more than a million people and threatening mudslides in fire-scarred areas.

Flights were grounded in Northern California as gusts reached 80 mph during the second wave of an arctic storm that sent trees crashing onto houses, cars and roads. Forecasters expected the storm to dump as much as 10 feet of snow in the Sierra Nevada by Sunday.

The heavy snow was slowing search efforts for a family believed to be missing in the mountains, authorities said.

Highways from Sacramento to San Francisco were closed because of debris or toppled big rigs blocking lanes, and local roads were flooded.

More than a million people from the Bay Area to the Central Valley were in the dark. Crews worked to restore power, but it could be days before all the lights are on, said Pacific Gas & Electric spokeswoman Darlene Chiu.

In Southern California, authorities in Orange County urged residents of three fire-scarred canyons to flee beginning Friday afternoon. The order also called for the mandatory evacuation of large animals from the mudslide-prone canyons, where 15 homes burned last fall in a 28,000-acre wildfire.
