Summer Exiting on Remnants of Storm

A dash of rain, a pinch of humidity, a cup of clouds. Mix it all together and voila-- it’s the recipe for “The Last Chance, Last Weekend of Summer Weather Forecast.”

The overcast and muggy conditions that began earlier this week are not expected to end until Sunday, said National Weather Service forecaster Wilbur Shigehara. There is a 50% chance of showers today that could dump as much as 0.25 of an inch of rain on the county, he said.

Tropical Storm Octave, which originated as a hurricane about 500 miles southwest of San Diego, is the cause of this sudden blast of moist, hot air and the possibility of rain, Shigehara said.

“It’s not unusual for us to get the remains of a hurricane at this time of year,” he said. “Late August, early September is the height of the hurricane season, but we have been known to get the tag ends of hurricanes as late as this.”

High temperatures in the county Friday included 95 in Campo and 93 in Santee and Poway. The high at Lindbergh Field was 80.

Highs at the beach today will be 75 degrees, dipping to 70 on Sunday, Shigehara said. The surf is at 3 to 5 feet, and the ocean temperature is 67.

Conditions along the coast will be “cloudy and hot” with highs in the low 80s today, Shigehara said. Overnight lows are expected to be 65 to 68.

Inland areas will also feel the heat, with a 94-degree high today, Shigehara said. Overnight lows ranging from 60 to 66 are predicted.

Daytime highs in the mountains will range from 78 to 85 today and from 75 to 80 Sunday, Shigehara said. Lows of 50 to 55 are expected.

The forecast calls for desert highs to be from 103 to 108 today, decreasing to the low 100s by Sunday. Overnight lows of 72 to 80 are predicted.
