SAN DIEGO -- A San Diego heat record of 84 degrees was set at Lindbergh Field today, breaking the previous record of 82 that had stood for 137 years, according to the National Weather Service.
The warming trend was caused by weak Santa Ana winds combined with low humidity, Forecaster Brent Albright said.
"It's what happens if you get the right set-up, a big ridge of high pressure off the coast combined with offshore winds," Albright said.
"We should have another warm one tomorrow with the potential for another record at Lindbergh Field."
Humidity in the single digits was recorded in some parts of the county Sunday. Lindbergh Field had 15 percent humidity when the record was broken at 2 p.m.
The warmest locations in the county include MCAS-Miramar with a high of 91 degrees, Gillespie Field in El Cajon with a high of 90 and, 89 degrees recorded at Santee, Escondido and Mission Trails Regional Park.
A cooling trend was expected to begin Tuesday with a slight chance for rain by next weekend, according to Albright.
