Monsoon moisture is still centered right over the Northstate. You can expect cloudy conditions with threat of showers and thunderstorms through tonight.
Current measurments of moisture from the ground to the mid levels of the atmosphere are running well above normal (4.2 standard deviations above normal). This moisture plus daytime heating and a weak distrubance moving close to the Northcoast will continue to spark showers and thunderstorms.
This threat will likely last into Friday though chances should drop drastically, as southwest winds aloft should begin to push moisture closer to the crest.
Ahead of our next trough, we'll likely see a quick bump in afternoon highs Saturday but temperatures should quickly drop to the low 90s by Sunday and Monday. The forecast get tricky with another strong ridge of high pressure building over the Desert Southwest and this overall troughy pattern just offshore of California. If the ridge amplify and shoves further west closer to California, we would see hot te4mperatures once again. We will just have to watch closely until forecast model confidence increases.
