A soggy Halloween is predicted for Sacramento with the arrival of much-needed rainfall today.
Following a dry commute Friday morning, a slow-moving Pacific frontal system will make its way through Northern California, bringing rain to the lowlands and snow to the mountains.
“For the Sacramento area the rain won’t hit until around noon to 2 p.m.,” said Mike Smith, meteorologist for the National Weather Service. “Then, the bulk of it, the center of the front, will go through about 5 o’clock this evening.”
Smith said the rain should then continue on through the evening hours – during primetime for trick-or-treating and high school football. The rain should end about 11 p.m.

Showers are forecast to continue on-and-off on Saturday. Sunday looks clear.
The Giants parade in San Francisco to celebrate another World Series championship also looks wet.
“The frontal passage looks to be just about noon, right when the parade starts,” said Smith. “I would not be a bit surprised to see cars with rain on them in the parade.”
Rainfall amounts from 5 to 11 p.m. Friday in the Sacramento region are predicted to be moderate: 0.41 in Sacramento, 0.37 in Roseville, 0.18 in Yuba City, 0.41 in Placerville and 0.38 in Auburn.
The approaching Pacific cold front is also expected to bring several inches of snow to the Sierra Nevada above the 6,000-feet-elevation level. The bulk of the snow is expected tonight.
Both Interstate 80 and Highway 50 are likely to see enough snowfall to prompt mandatory snow chain requirements. Winds are expected to be gusty as the snow falls.
