Halloween revelers could get a trick rather than a treat as a rain storm is expected to arrive Wednesday night and stay through Thursday afternoon, the National Weather Service said.
The storm will drop temperatures in the foothills into the mid-60s during the day. Lows at night will dip into the low-40s.
That compares to the weekend high of 78 in Sonora and 82 in Angels Camp.
Temperatures in the Mother Lode will be slightly above average for this time of year today, but sunny skies are forecast to give way to clouds Wednesday with showers likely on Thursday.
There is a 30 percent chance of snow at 4,900-foot elevation.
Dodge Ridge Ski Area recorded 13 inches of snow last week but it did not last. As of this morning, the resort reported no snow at the base and summit. However, the resort expects to see new snow from the incoming storm.
After last week's rain and snowfall, Ebbetts pass remains closed. Tioga Pass and Sonora Pass are open.
As of Halloween last year, Sonora recorded 2.10 inches of rain while Angels Camp had 2.67 inches. This year has been dryer, with only 0.90 inch of rainfall in Sonora and 0.83 inch in Angels Camp.
