Weekend to Be Mostly Sunny Except in Mountains

A high pressure system may bring scattered thunderstorms to the mountains and deserts today and Saturday, but skies elsewhere will be mostly sunny through the weekend, forecasters say.

A high pressure front is allowing moisture from southern Arizona and northern Mexico to flow into San Diego, which could cause afternoon and evening thunderstorms in the mountains and deserts, said Harvey Hastrup, forecaster for the National Weather Service in San Diego.

But, after a cool, overcast summer, areas west of the mountains can expect a little more sunshine and near normal summer temperatures over the weekend, Hastrup said.

Highs in the inland areas will range from 86 to 94, with the mercury in the foothill areas such as Fallbrook shooting up to 100 degrees, Hastrup said. Nighttime temperatures are expected to dip to 55 to 63.

Along the coastal strip, which includes the city of San Diego, the night and morning clouds will clear by mid morning, allowing temperatures to rise to 75 to 84, Hastrup said. Nighttime lows will drop to 60 to 69, he said.

At the beaches, the clouds will linger through the afternoon, keeping temperatures in the 70- to 75-degree range, Hastrup said. The ocean temperature is 67 degrees, and the surf is 1 to 3 feet.

In the mountains, highs will reach 82 to 90, and nighttime temperatures will fall 54 to 62, Hastrup said.

In the deserts, he said, the mercury will soar to 102 to 110 and only through the night will fall only to 74 to 82.
