More significant changes are on the way when it comes to the forecast. A weak cold front is going to sweep over the region Friday, bringing temperatures down to the 50s and low 60s as well as a slight chance of rain. The GFS is showing rain chances by late morning and early afternoon across San Luis Obispo County, although it may be more in the form of drizzle and mist.
Ahead of these changes, the Central Coast will get one more day of slightly above average temperatures. Although these daytime highs are technically trending back down, peak temperatures will be from the 60s and 70s with mild to moderate winds up to 20 miles per hour. Overall, Thursday will be pleasant.
Rain chances will continue through the weekend as shower activity is also possible early Saturday afternoon across southern San Luis Obispo County and Santa Barbara County. Snow levels will also begin to fall to 3,500 to 4,000 feet. The next chance for rain will be Sunday afternoon through Monday as a low-pressure system moves in over the area. This rain system will produce anywhere from 0.33''-0.5''.
More significant rainfall is possible by Wednesday and more details will be discussed on that as the event nears.
