The National Weather Service is advising San Diegans to enjoy the cooler temperatures this weekend because a heat wave could be on its way.
How hot will it get? “Stay tuned!” the NWS tweeted Friday afternoon.

“A trough of low pressure will provide cool weather, a deep marine layer and areas of strong winds in the mountains and deserts through Saturday,” the NWS reported. “A high pressure system is forecast to move into the area next week, bringing warmer weather and fewer coastal clouds.”
But forecasters are uncertain about how toasty it will get.
“You’ve probably heard about high pressure strengthening and bringing us hot weather late next week. Model guidance has come into better agreement about that increasing high pressure, but has delayed it,” the NWS reported. “Plan on hot inland weather [next] weekend, but how significant the warmup will be is still uncertain.”
The current forecast calls for daytime high temperatures across the coastal region in the high 60s to low 70s through July 4, with inland valley temperatures about 10 degrees warmer for the same period.
