Marine layer returns, cools San Diego

SAN DIEGO (KUSI) — Temperatures are beginning to cool and humidity is diminishing, but mountains and deserts still have a chance of some rain.

There is a 20 percent chance of light showers and thunderstorms Thursday for the mountain and deserts, as monsoonal moisture remains.

By Friday, a ridge of high pressure will weaken, allowing for the return of onshore flow. This will cause temperatures to cool as the marine layer covers the county.

A National Weather Service beach hazards statement remains effect until 5 p.m. Thursday. Waves and surf of 3 to 5 feet is possible, along with potentially dangerous rip and longshore currents, throughout the remainder of the advisory period.

High temperatures Thursday are expected to be about average for this time of year: 75 degrees along the coast, 88 degrees inland, 81 degrees in the mountains and 106 for the deserts.
