Expect a smattering of rain and possible thunderstorms to keep Saturday damp in Sacramento.

“We have a good chance of showers – 70 percent,” said Karl Swanberg, forecaster for the National Weather Service’s Sacramento office. “There’s also a slight chance of thunderstorms in the afternoon. Tonight will be mostly cloudy with a 40 percent chance of rain.”

Thunderstorms also may pop up in the early evening, Swanberg said. Southerly winds, with gusts of 15 to 25 mph, will keep the tail end of this storm system moving through before Sunday.

“There’s still a slight chance of rain Sunday, but then we’ll start drying out,” Swanberg said.

Sacramento received 0.37 inches of rain Friday, bringing our January total to 5.34 inches.

“That’s above normal for the month,” Swanberg noted. “Since the rain season began Oct. 1, we’re at 91 percent of average.”

No more rain is expected Monday through Thursday. Instead, plan for fog.

“A typical fog pattern is developing with late night and early morning fog,” Swanberg said. “It could be locally dense.”

Daytime skies will be partly cloudy with temperatures in the mid 50s and overnight lows in the low 40s.
