Rohnert Park Readies For Rain

ROHNERT PARK , CA — A weather system that arrived Monday is forecast to usher in gusty winds, frigid temperatures and some much needed precipitation toward the end of the week, weather officials said.

The low pressure system is also likely to bring snow to the Sierra Mountains, rain to the mountains of the North Bay and across Sonoma County.

Another weather system is expected to bring wet weather as early as Wednesday into early Friday.

A third storm system is likely to bring more rain on Saturday and Sunday, according to the National Weather Service.

Overnight temperatures are expected to plummet in areas away from the immediate coast and could drop into the upper 20s and 30s. Temperatures in the lower 40s are expected along the coast and bays.

There’s also a medium to high possibility of freezing temperatures within the North Bay Valleys, southern inland Monterey County and much of San Benito County, forecasters with the NWS said this week.

“This is a good reminder to both protect sensitive vegetation and to check on those without access to adequate heating during this period of colder weather,” forecasters wrote.

“Despite some sunshine it will feel colder today as a dry cold front sweeps through. A cold front currently over NorCal will pass through the Bay Area and Central Coast later today,” NWS meteorologists wrote in a Bay Area forecast discussion Monday.

In Rohnert Park temperatures are expected to hit a low of 30 degrees on Monday night and rain is likely to start Thursday. Another round of rain is expected to fall in the area on Saturday.

"This would be considered a weak atmospheric river coming through," Sarah McCorkle, a forecaster with the weather service, told SFGATE. "It's pulling moisture from the tropics. A stronger atmospheric river would pull in more moisture. We're seeing a lower-end amount."

Forecasters said there are “good odds” for the North Bay and coastal ranges to see an inch or more of rain this week.

“A bit less for the inland valleys. Rain should return for the weekend with less confidence in timing and amounts,” NWS officials tweeted.

The rain is much needed as Northern California continues to experience severe drought conditions that are expected to persist as unseasonably warm and dry conditions are likely to push into the holiday season and beyond, according to the latest update from the national Climate Prediction Center.

“It should be no surprise that the winter outlook is consistent with typical La Niña impacts, which include a general warmer and drier south, and cooler and wetter north," Jon Gottschalck, chief of the climate center’s operational prediction branch, told the Los Angeles Times.
