Scattered rain showers are expected and light snowfall is possible Thursday in San Diego County as the first rain event of the fall season comes to an end this evening, according to the National Weather Service.
A cold, low pressure system currently centered over San Bernardino County will weaken Thursday and continue moving east, but the system is expected to produce rain showers and possibly up to an inch of snow in the mountains, NWS meteorologist Miguel Miller said.
Snow levels were around 5,000 feet early this morning, but the levels will rise to about 6,000 feet by this afternoon, Miller said.
As of 7:30 p.m. Wednesday, 2 inches of snow had fallen at Palomar Mountain and Birch Hill, while a half-inch was reported at the Mount Laguna Lodge.
Light to moderate rain showers will continue Thursday everywhere except desert areas, where scattered showers are expected, forecasters said. Coastal areas, the inland valleys and the mountains have a 70% chance of precipitation Thursday and the deserts have a 20% chance.
