Although we've had gusty wind at times around northern California today, we've had pleasant weather for mid-April. We can expect isolated showers over the mountains, and then fewer clouds for everyone through tomorrow morning. The area of low pressure which brought the strong wind, cooling trend and mountain rain and snow showers is now being pushed out of the region. We can expect a mostly clear sky tonight with weakening wind and cooler temperatures. Lows will range from the 20s and 30s in the mountains to the 40s and lower 50s in the valley and foothills. Thursday will be mostly sunny to partly cloudy and slightly warmer for everyone. Highs will range from the 60s in the mountains to the 70s in the valley.
A strong ridge of high pressure will begin building over California and much of the West Coast on Friday. That will mean even more sun and warmth Friday through the weekend. High temperatures will end up 15-20 degrees above average by Sunday for many locations. A trough wants to move over northern California during the first half of next week. We'll have more clouds Monday, a chance of mountain showers Tuesday and Wednesday, and a slight chance of valley rain showers. If the rain actually falls, it'll only be a few hundredths or tenths of an inch. Overnight lows will remain warmer than average due to the warming airmass. Valley highs will climb from the 70s to the upper 80s and lower 90s before cooling next week.
