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.
