Unusually cool weather is moving through Northern California, bringing rain, thunderstorms, lightning and a slight chance of snow on mountaintops.
The National Weather Service reported Thursday that low pressure over the region is pushing temperatures 15 to 20 degrees below normal.
The forecast calls for scattered thunderstorms and lightning in the mountains and isolated showers in the valleys.
Temperatures in the Sacramento area is expected to drip to the mid-70s.
Forecaster Angus Barkhuff says the snow level could fall to 8,500 feet, which is too high to affect most people.
Barkhuff says the system should be cleared out by Friday, with temperatures warming back up over the weekend.
