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.

The center of a closed low pressure system will move slowly eastward to a position near Point Conception by Thursday morning, then move more rapidly northeastward into Nevada by late Thursday evening. This will continue the cooling trend through Thursday with Thursday high temperatures as much as 15 to 20 degrees below average for the mountains. High temperatures on Thursday for the coast and valleys will be mostly in the 60s to around 70 with the mountains in the 40s and 50s. An initial band of showers and isolated thunderstorms will move into coastal areas inland to the mountains during the afternoon and early evening with a second round during the late evening and overnight. Instability will increase overnight as colder air aloft moves across record warm coastal waters for this time in October, around 7 degrees warmer than the long-term average. While coverage of precipitation may be less overnight, there is greater potential for brief higher-intensity rainfall from isolated thunderstorms and stronger showers. Additional showers will continue on Thursday along with a slight chance of thunderstorms during the afternoon. The greater coverage is expected for Orange and southwestern San Bernardino Counties from the coast to the mountains. Showers will continue into Thursday evening, then decrease and end from the northwest late Thursday night and early Friday. Through Thursday night for Orange and southwestern San Bernardino Counties, rainfall is expected to range from around 0.75 inch near the coast to 1 to 1.5 inches for the San Bernardino County mountains. For San Diego County, rainfall will decrease from north to south with 0.75 to locally 1 inch over northwestern San Diego County to 0.25 to 0.50 inch across far southern San Diego County.

Probabilities for 0.50 inch or more exceed 80 percent from the coast to the mountains. Probabilities for 1 inch or more exceed 50 percent from the coast to the mountains for Orange and southwestern San Bernardino Counties into northwestern San Diego County. Probabilities for 2 inches or more exceed 10 percent from inland Orange County to the mountains of southwestern San Bernardino County and are as high as 20 to 30 percent on the coastal slopes of the San Bernardino County mountains.
