SAN DIEGO -- Noticeably cooler weather, gusty winds and a chance of evening rain may provide San Diego County some welcome relief Thursday from the record-breaking winter heat wave.

Quite a few daily high temperature records fell around San Diego County Tuesday. A 92-degree high in Chula Vista was 11 degrees higher than the previous milestone for Feb. 16, set in 2013; highs of 93 degrees in El Cajon, 91 in Escondido and 89 in San Diego each topped by 7 degrees records, set in
2013 and 1981, respectively; and a 91-degree high in Vista was 6 degrees over the prior record from 1977, according to the National Weather Service. An 82-degree high in Oceanside was 4 degrees over and a high of 88 degrees in Ramona was 1 degree higher previous records, both set in from 1977.
On Monday, daily temperature records were set in Borrego Springs, Chula Vista, El Cajon, Escondido, Oceanside, Escondido and Vista.
But forecasters said today would be much cooler as a Pacific storm approaches the region. A chance of light to moderate showers is in the forecast in most areas this evening into Thursday.
High temperatures today were predicted to be 68 to 73 degrees near the coast, up to 76 degrees inland, 75 to 80 in the valleys, 68 to 74 degrees in the mountains and 82 to 87 degrees in the deserts.
Cooler weather is expected to persist through Friday, but it will warm up again this weekend, according to the weather service.
Strong southwest winds are also expected in the mountains and upper deserts today as the cold front approaches.
A National Weather Service wind advisory for the mountains will remain in effect from 4 p.m. today to 10 a.m. Thursday. Winds of 20 to 35 miles per hour will be possible, as will gusts that could reach 60 mph in some areas.
Forecasters said the gusty wind might make for difficult driving conditions, especially for motorists in high-profile vehicles. Drivers were urged to use extra caution as blowing dust could lead to visibility being reduced, and the wind may be strong enough to send broken tree limbs and other debris into the roadway.
