Warm Days Will Linger, but Sticky Humidity Is Expected to Evaporate

More of the same, but minus the moisture.

San Diegans shouldn’t expect dramatic changes in the weather patterns that have visited the area over the past few days, but the humidity that has arrived earlier than usual this summer should be gone by today.

“It’s still going to be warm,” said forecaster Dick Stitt of the National Weather Service in San Diego. Temperatures reached a high of 74 Monday at Lindbergh Field, one degree under the normal high for the date.

“There will be no major changes, except that it will be a little more pleasant and less humid,” he said.

The high-pressure system that brought moisture and scattered showers to parts of San Diego County on Saturday and Sunday did a repeat Monday, this time limiting the precipitation, in the form of thundershowers, to the local mountains and Borrego Springs.

Mt. Laguna recorded 0.26 of an inch of rain, Palomar Mountain had 0.30 of an inch and Borrego Springs recorded a quarter inch. Relative humidity reached as high as 87% Sunday and Monday.

The high-pressure system is gradually heading east, on its way to Arizona and beyond, Stitt said.

“The warm air that brought moisture all over Southern California is moving off to the east. We’re drying out,” he said.

The showers that took Los Angeles by surprise Monday narrowly missed much of San Diego. The warm, subtropical air from Mexico--flowing southeast to northwest--overshot San Diego and instead fell on Los Angeles and parts of San Bernardino and Riverside counties.

“It was just one of those situations,” Stitt said. “It just missed us.”

Predicted for San Diego today and Wednesday are morning and night coastal low clouds, with the sun breaking through in the afternoons.
