Warmer with Monsoonal Moisture Moving In
Inland heat will continue for the next few days with slightly warmer than normal but comfortable temperatures on the coast. The big monsoonal ridge to our east has strengthened a bit and is exerting more influence over California—and will through mid-week. That’s why inland temperatures will be running 5-15ºF above normal. The ridge, working with a subtropical low off of Southern California will also advect a stream of moisture across Central California. This will mostly likely manifest in some mid to high level cloudcover, but there may be a slight chance of a high based shower or dry thunderstorm on Wednesday—mainly early in the day. The ridge weakens and moves to the east after mid-week which will allow for cooler weather.
