A moderate storm from the Gulf of Alaska is expected to drop southeast into Northern California this week, according to the National Weather Service.
The storm will most likely affect the morning and afternoon commutes in Sacramento on Wednesday. Perhaps a quarter to a half-inch of rain could fall.
Thunderstorms are possible both Wednesday and Thursday in the Sacramento Valley. Look for high winds to occur Tuesday and Wednesday, with gusts as high as 30 mph in Sacramento.
In the Sierra, snow levels could lower to around 3,500-feet elevation on Wednesday. Travel is expected to be difficult on Interstate 80 and Highway 50 beginning Tuesday.
Perhaps a foot of snow could accumulate near the 5,000-feet level, including the I-80 and Highway 50 transportation corridors.
Today is expected to be sunny with Sacramento temperatures in the high 60s.
