It was a day of sunny and smoky heat for much of northern California as several fires continued to burn in our area. Isolated showers and thunderstorms are still possible over the Sierra through the early evening, but will disappear once the sun sets. Lows tonight will range from the 50s in the mountains to the 60s and lower 70s in the valley with some areas of smoke and a mostly clear sky. Wednesday will be another mostly sunny to sunny day with smoke in the air and isolated mountain thunderstorms. Highs will be mainly in the 90s, with a few upper 80s in the mountains and a few lower 100s in the valley.
A trough of low pressure will move over northern California for the latter half of this week. We can expect isolated mountains showers and thunderstorms, moderate breezes and slightly cooler highs through Thursday and Friday. Another rige of high pressure will begin building back over the West Coast this weekend and next Monday for another warming trend. A second trough will approach next Tuesday, and that will again bring a few more clouds and the beginning of a modest cooling trend. Highs will remain fairly seasonable for all, staying mainly in the 90s, with a few upper 80s and a few lower 100s.
