The science of fog
Rain is returning to Sacramento and heavy snow will fall in the mountains this week.
Forecasts call for 1 to 2 inches of rain in Sacramento between Tuesday and Friday, according to the National Weather Service.
Multiple weather systems passing through Northern California will impact the area, bringing snow and potentially “major mountain travel impacts,” NWS Sacramento said Monday in a tweet. Those traveling on mountain passes on Interstate 80 and Highway 50 should expect delays, chain controls and reduced visibility.
NWS issued a winter weather advisory from Tuesday through Wednesday night, with 3 to 6 inches of snow at the northern Sierra pass anticipated. A winter storm watch was also issued for a large portion of the Sierra, effective Wednesday evening through Friday.
Some parts of the Sierra could see up to 32 inches of snow. Snow could fall as low as 3,500 feet, NWS said on Twitter.
Conditions also include dense patches of fog in the San Joaquin valley, including Stockton and Modesto, as well as Sacramento on Tuesday.
Last week, Sacramento received its first significant rainfall in nearly six months. It rained a total of 0.9 inches in downtown Sacramento last Wednesday and Thursday. Prior to that, a small sprinkle in October (about 0.04 inches) was the only other rainfall recorded in the Sacramento region since May.
