After a record-hot Thanksgiving weekend, a one-day cold front is expected to move into Southern California on Monday, according to the National Weather Service. Forecasters gave about a 30 to 40 percent chance that rain falling in the Central Coast area Sunday night would extend into Southern California on Monday morning. If precipitation does arrive, the weather service said, it was likely to be very light, maybe just sprinkles. The foothills on the coastal sides of the mountains have the highest rainfall potential, up to a quarter-inch.
