Sacramento eyes third-wettest October on record; snow to fall in Sierra

A wild weather day is headed to Sacramento and the Sierra on Sunday.

There’s a good chance of thunderstorms and hail in the Valley, with wind gusts up to 25 miles per hour. Up to half an inch of rain is in the forecast, adding to a monthly total that has made this the fourth-wettest October on record in Sacramento.

The rain over the next few days could push this month into the No. 3 spot for wettest Octobers on record. After receiving .79 inches of rain on Friday, downtown Sacramento now has recorded 3.73 inches of rain this month. The third-wettest October occurred way back in 1899, when the city saw 4.46 inches of rain.

The record for October was 6.85 inches in 1962 and the average is 1.05 inches.

Up the hill, the National Weather Service expects snow levels to drop to around 6,000 feet on Sunday. It could get particularly perilous at the passes, with snow expected to fall at a rate of one inch per hour between 11 a.m. and 5 p.m.

“It’s going to be an interesting day,” National Weather Service forecaster Travis Wilson said. “It’s a good day to keep an eye on the weather.”

After a brief break, there’s bad news in the forecast: Wilson said there’s a good shot for light rain to hit the area after 5 p.m. on Monday - just in time for Halloween.
