Former Tropical Storm John took a poke at Southern California, bringing weather we ordinarily see in March or April rather than September. While the moisture is still being flung our direction, the jet stream is taking it further to the North, and I think our shower threat is pretty much done. We could see a few terrain-driven thunderstorms here and there in the mountains, but here in the Valley we should stay sunny and dry.
High pressure building into New Mexico and Arizona will expand west as we approach this weekend, bumping our temps up a little. For places like Woodland Hills and Chatsworth, temperatures will bump up a lot, approaching the century mark. Here in Studio City, we can expect the lower 90s, maybe 95. With the clock-wise rotation of the high pressure system, we could see some monsoonal moisture creep into the SoCal area, though any thunderstorm activity should stay confined to the mountains and deserts.
Cooler temperatures are expected to return on Monday thanks to a low pressure trough and the return of onshore flow. These two normally allow the marine layer to expand far onshore, so we could see some morning low clouds and possible fog, though that should quickly clear to sunny skies.
