Brief but significant monsoonal surge

Quick update this afternoon. The poorly-modeled monsoonal surge (but aren’t they all?) is already underway, with flash flooding already having been reported in Twentynine Palms and more thunderstorms popping elsewhere. Tuesday/Wednesday will be the main days for shower/thunderstorm potential, and due to the very high PWs as high as 1.75 inches flash flooding will probably be more of a threat than dry lightning. Some storms are possible in the Bay Area and especially over far northern coastal areas as a result of some moisture pooling off the coast which will be able to interact with a coastal wave. Coastal SoCal may actually have lesser chances for thunder with this event than Eureka, for example.  More later…
