Expect a warm start to the work week, but prepare for cooler temperatures ahead and possible rain as early as Thursday, the National Weather Service said Sunday.
A high pressure system that’s bringing ideal weekend weather to San Diego will continue with temperatures mostly in the 70s through Monday and into Tuesday, but the system will gradually weaken by Wednesday, according to the NWS.
Forecasters are watching a low-pressure system that is “diving southeast toward California” and is expected to hit the San Diego area late Wednesday.
“The moisture looks somewhat limited, so precipitation amounts will not be much–most likely 1/2 inch or less, according to the NWS.
But a more vigorous trough could bring “more substantial rainfall later in the week, perhaps around Saturday,” the NWS continued.
“Neither of these systems taps into much cold air from the north, so snow levels should stay rather high, mostly 7,000 feet or higher,” the NWS said.
