SAN DIEGO (KGTV) — The following seven days will bring everything from summer-like conditions with the potential for record-breaking heat to fall-like weather with the chance for rain. However, the heat will be the big story for the next couple of days.
A building ridge of high pressure, also known as a dome of warm air, will move through southern California, elevating daytime highs through Friday. Ramona, Palomar Mountain, and Borrego Springs have the potential to break daytime record highs.
The expected heat has triggered a Heat Advisory for most of Thursday for the inland communities. Those susceptible to heat-related illnesses should use extreme caution by limiting time outside, staying hydrated, and taking frequent breaks in the shade if working outdoors. Daytime highs across the county will climb 5-20 degrees above seasonal.
The ridge is in and out. Saturday will be our transition day into a big cooldown, with temperatures plummeting 15-20 degrees by Monday. The strength and direction of a storm system to our north will determine if we see showers on Sunday and Monday. As of Wednesday, the chance for showers is minimal. However, you can expect a thicker marine layer starting Sunday morning, with the potential for light showers or heavy mist.
A swell from the West and northwest will cause high surf with sets anywhere from 4-8 feet, most elevated towards the South Bay beaches. The rip current risk will be high; inexperienced people should avoid the water or swim near a lifeguard.
Thursday's Highs:
Coast: 76-91
Valleys: 89-98
Mountains: 85-93
Deserts: 99-102
