Get ready to be whipsawed by the weather as the weekend’s unseasonable summer-like heat turns into a cold winter rainstorm.
A marked cool-down on Tuesday — sending temperatures dipping about 10 degrees across the county — will usher in the inclement conditions, with showers likely beginning in the evening hours, according to the San Diego office of the National Weather Service.
More widespread precipitation and even lower thermometer readings are expected Wednesday, the agency advised.
By the time the rain dwindles out on Thursday, the storm clouds will have left behind roughly a half-inch to one inch of moisture along the coast, up to two inches in the mountains, and under a quarter-inch in the deserts.
The snow level is likely to drop to around 6,000 feet over the period, bringing a chance for some dustings of frozen flakes on the very highest mountain peaks.
Due to the expected intensity of some of the cloudbursts, the weather service issued a flash-flood watch from the coast to the East County highland communities, effective Tuesday evening through late Wednesday night.
The forecast caused the Del Mar Thoroughbred Club to cancel races on Thursday out of concern for the safety of horses and jockeys.
Fair and warmer conditions are expected to resume next weekend as a weak high-pressure system moves in from the west, the weather service advised.
