Mountain snow is expected to begin late Wednesday through Thursday night across the Sierra.
Most of the northern and central Sierra will see between 5 to 10 inches of snow fall by Friday morning, with as much as 20 inches possible locally at higher elevations.
Snow will fall above 6,000 feet, according to the NWS. Travel delays are likely on Highway 50 and Interstate 80, where snow could result in significant reduction to visibility near the summit. Chain controls are possible.
The NWS has issued a winter storm watch, in place from the start of Thursday to 6 a.m. Friday.
