Weak troughing along the West Coast will maintain the onshore flow generating the typical marine layer down below late night & morning hours with partly cloudy skies and gusty west winds at times in the mountains. We'll also see a few afternoon clouds out there today as highs reach the lower to mid-70s, west winds gusting 15-25 mph during the afternoon. Residual mid and upper level moisture may spark afternoon shower or thunderstorm on Saturday, mainly across the eastern San Bernardino Mountains and Deserts. While instability is there, pw's are low, so anything that develops will produce sprinkles, maybe an isolated downpour with a rumble of thunder. A little warmer this weekend with highs in the mid-70s Saturday, warming to the upper 70s on Sunday as overnight lows cool to the 40s. High pressure will expand westward back over the region next week bringing a gradual warm-up, even signs we could see a little monsoon moisture return later in the week.
