A trough moving inland across California Thursday was expected to deepen the marine layer west of the mountains through Friday and bring gusty mountain and desert winds, the National Weather Service said.

There could be some patchy drizzle for late Thursday night into early Friday morning, but with chances for measurable precipitation mostly 5% or less, forecasters said.

Along the coast Thursday, it was expected to be partly cloudy in San Diego County with high temperatures around 70 degrees, the NWS said. The valleys were expected to be mostly sunny with highs from 71 to 76. It will be mostly sunny in the mountains with highs from 67 to 77. The deserts were expected to be mostly sunny with highs from 92 to 97.

The weekend should be a little warmer with weak high pressure. Early next week, a second trough could bring another round of gusty mountain and desert winds, the NWS said.

Late next week, high pressure from the east was predicted to bring warmer conditions going into July with high temperatures rising to near average by the end of next week and above average in the deserts.

Occasional west-northwest winds gusting near 20 knots in the outer coastal waters were expected each afternoon and evening through early next week.
