The weather around most of California heated quite a bit on Thursday, and much hotter weather is ahead. An Excessive Heat Warning is now in effect for much of our area from Friday through next Wednesday due to dangerously hot days and warmer than normal nights. Tonight will be mostly clear to clear with lows ranging from the 50s in the mountains to the 60s and 70s in the foothills and valley. Friday will be another mostly sunny day with hotter highs and isolated showers and thunderstorms over the mountains. Highs will range from the upper 80s and 90s in the mountains to the 90s and lower to mid 100s in the foothills and the valley.
A strong ridge of high pressure will remain in control of the weather over the western United States this weekend through most of next week. We can expect in increase of clouds from the tropics with isolated showers and thunderstorms possible, mainly over the mountains. Stronger breezes will also be possible, but despite our increase in clouds, the heat will become potentially dangerous at times, with very little relief overnight. A small trough of low pressure won't cool our weather much next week, but late next week cooler weather should arrive. Highs for all areas will be in the 90s and 100s, with highs between 100 and 110 possible in some areas.
