Tuesday brought more wind and warmth to northern California with plenty of sunshine. A strong ridge of high pressure will deliver a very warm Wednesday before another rapid shift in our weather pattern arrives. The overhead ridge rapidly warmed us today, and we haven't finished with that warming trend yet. Tonight the wind will begin to weaken and we'll have a mostly clear sky. Despite the lack of clouds and wind, the lows won't be too cold, ranging from the 30s in the mountains to the 50s in the valley. Wednesday will be mostly sunny and much warmer with weaker wind. Highs will range from the lower 70s in the mountains and foothills to the mid and upper 80s in the valley. Some lower 90s are possible.
Our weather pattern will change fairly rapidly starting Thursday as the jetstream will push further south and will be more or less directly over northern California from late this week through the weekend. A large trough will also be in place over the West Coast, and two to three small disturbances will move through the trough and over our region. The proximity of the jetstream will mean we can expect stronger wind at times from late this week through Sunday, although it won't be constantly windy. The small disturbances will also bring chances of valley rain and mountain rain and snow. Amounts of precipitation won't be heavy, however. Our weather pattern will settle a bit more early next week, with a modest warmup.
