Another Heat Record for Ramona; Cooling Trend On Its Way

A spell of unseasonably high temperatures in San Diego County will conclude today before a cooling trend sets in for the rest of the week, meteorologists said.

The heat wave that began last weekend is being caused by a ridge of high pressure over the region, according to the National Weather Service.

Several record-high temperatures were recorded around the county on Monday, including 100 degrees in Ramona and Campo, and 101 in Escondido. The previous record high for a May 13 in Ramona was 98 degrees, set in 1976. In Campo, the previous record-high was 95 degrees set in 1984, and in Escondido, it was 99 set in 1979.

Highs today were expected to be in the low to mid 70s near the coast, high 70s to low 80s inland, mid 80s in the western valleys, high 80s to low 90s near the foothills, low to high 80s in the mountains and 105 to 110 degrees in the deserts.

Also today, areas of dense morning fog were likely in coastal zones and far western San Diego County valleys. The weather service issued a dense fog advisory for coastal areas until 9 a.m.

The agency also scheduled a wind advisory for mountain and desert areas from 3 p.m. to 3 a.m. Wednesday, saying sustained winds of 20 to 30 miles per hour were likely, along with gusts up to 45 mph.
