From the National Weather Service office in SGX, issued 1 hr ago

Synopsis

A low pressure system moving southward off the California coast will bring general cooling through Thursday. It is also expected to produce showers and a slight chance of thunderstorms for late today through Thursday as it moves inland through California into Nevada. Warmer and drier for the weekend. Offshore flow on Saturday could produce gusty northeast to east winds in and below mountain passes and canyons as well as the Inland Empire corridor between the Cajon Pass and the Santa Ana Mountains. The offshore flow weakens for Sunday into early next week.

Aviation

211130Z...SCT-BKN cloud layers around 2000 and 8000 feet MSL will continue into the afternoon. A band of RA/SHRA will move west to east through the region 21-06Z. Cigs will drop to 2500-3500 feet MSL and vis 3-6SM during this band's passage. A few embedded +SHRA/TSRA could produce brief and local IFR conditions. Winds shift from south to southwest and cigs lift to about 3000 feet MSL as the precip band passes after 11Z Thursday followed by SHRA.

Marine

A storm system will move through the coastal waters this afternoon through early Thursday. Southerly winds today will shift to southwest tonight, then westerly Thursday, with occasional wind gusts exceeding 20 knots. There is a 15-25% chance of TSRA after 22Z into Thursday. No hazardous marine conditions are expected Thursday night through Sunday.
