The heat peaked on Wednesday with cooler conditions expected Thursday west of the mountains and temperatures forecast 5 to 10 degrees cooler, the National Weather Service said.

Records fell Wednesday at Oceanside Harbor, Vista and Chula Vista, according to the National Weather Service.

The high of 90 near the water at Oceanside beat the high of 82 from 1977, while at Vista the high of 98 surpassed the high of 95 almost 60 years ago, in 1964.

Chula Vista, also with a high of 98, saw the oldest record fall. The previous hottest October 19 was 92 years, since 1940.

But temperatures will drop through the end of the week, with the coolest conditions for most regions expected on Sunday.

As the low pressure system near the Pacific Northwest moves inland over the weekend, it will bring gusty westerly to northwesterly winds and a chance of precipitation in addition to cooler conditions. .

Winds will be strongest over the mountains in the deserts on Saturday with gusts of 60 to 65 mph.

There is a chance of showers in all parts of the county Saturday evening through Sunday and even high altitude mountain snow above 8,000 feet.

High temperatures on Sunday are expected to be 5 to 10 degrees below average near the coast, 10 to 15 inland and 20 degrees below average in valleys, mountains and deserts.

Low temperatures in the mountains could drop below zero for the first time since May on Sunday and Monday morning, the NWS said.

Forecasters are expecting somewhat warmer and drier weather with the possibility of another round of Santa Ana winds early next week.
