It's been another hot and smoky day for the valley of northern California, with showers and thunderstorms once again popping up over our mountains. It will quiet down tonight with more hot, active weather tomorrow. The sun's heat has once again combined with the residual monsoon moisture over our region to allow more mountain showers and thunderstorms today, and unfortunately more lightning is reaching the ground. The stormy weather will disappear after sunset tonight, with quiet weather through tomorrow morning. Lows will range from the 50s in the mountains to the 60s and 70s in the valley and foothills. Saturday will be hazy and hot with mountain t'storms. Highs will range from the 80s to the lower 100s.
We can expect fewer clouds Sunday compared to Saturday, but there will be another chance of mountain showers and thunderstorms. A trough of low pressure will push far enough onshore next week that we can expect a cooling of our weather to more seasonable levels, and a reduction in our cloud cover since the monsoon moisture will be pushed further east. There is the potential for some stronger wind late next week as the trough moves onshore, but it shouldn't be too strong. Valley lows will slowly cool over the first week of August from the lower and mid 70s to the mid and upper 60s. Valley highs will remain much more seasonable for the first week of the next month, ranging from the lower 90s to the lower 100s.
