If you thought last weekend was cold, prepare for even lower temperatures tonight.
According to AccuWeather.com, a private weather forecasting service, temperatures are expected to drop to 26 degrees Saturday night, about 12 degrees below the average temperature this time of year for Lodi. Last year's nighttime temperature on Dec. 7 was 42 degrees.
Sunday night temperatures are expected to drop even lower, to 24 degrees.
In addition to the freezing temperatures, the National Weather Service is predicting a 50 percent chance of rain, and has issued a hazardous weather outlook for much of Northern California, including northern San Joaquin County.
That hazardous weather includes a winter storm warning and freeze warning.
Ken Clark, AccuWeather forecaster for the West Coast, said snow is a definite possibility for the northern part of the county. He said Lodi and surrounding areas could see snow early Saturday morning. However, any potential snowfall will be short and not last through the weekend, he said.
"You certainly could see some wet snowflakes," Clark said. "The snow level will be very low. We're looking at a level of 500 to 1,000 feet, but we could certainly see snow or even sleet."
Clark added a snow advisory will be in effect in the Auburn and Tahoe areas, as well as the eastern hills of the San Francisco Bay Area.
The San Joaquin County Office of Emergency Services said a hard freeze warning was in effect through Friday. The office's website, www.co.san-joaquin.ca.us/oes, has several tips from the U.S. Department of Health and Human Services to keep warm when temperatures get extremely low, such as keeping several days' supply of food, water and medicine on-hand.
There are also tips for keeping your vehicle running in extreme cold, including replacing your windshield wiper fluid with a wintertime mixture, or replacing worn tires and checking the air pressure.
To keep warm, the Salvation Army's Hope Harbor shelter, located at 622 N. Sacramento St. will have an overnight warming center open Saturday night. Check-in will be between 6 and 8 p.m.
Nearby ski resorts are already seeing snowfall and gearing up for their opening day events.
Bear Valley Ski Resort along Highway 4 will open Dec. 20, and has seen about 18 inches of snow this week, according to the weather report on www.bearvalley.com.
The resort was expecting as much 12 additional inches Friday night and Saturday morning. Temperatures at Bear Valley were expected to be in the mid-20s during the day and the high teens at night.
Dodge Ridge in Pinecrest is also slated to open Dec. 20. The slopes there are expected to receive more than a foot of snow over the weekend, with temperatures as low as 20 degrees and as high as 28, according to a snow report at www.dodgeridge.com.
Kirkwood has been open since Nov. 25, and communications manager Kevin Cooper said current temperatures are as low as 5 degrees at the base of the mountain and 8 degrees at the peak. He said the high over the last four days was 22 degrees.
Cooper said Kirkwood has seen 36 inches of snow since opening day, and dozens of skiers have arrived early for the season.
"It's been super cold up here, which is great," he said. "With the next system coming through and the cold temperatures in the Bay Area, I'm sure we'll see a lot more skiers coming up. Everyone is anxious to hit the slopes this year."
Daytime temperatures in Lodi for the weekend include 44 degrees Saturday and 43 degrees Sunday. Temperatures are expected to warm up slightly to 50 degrees by Tuesday, but nights will remain chilly at 29 degrees.
