Remnant moisture from once Tropical Storm Mario will stream northward into the area through the end of the week, bringing widespread showers and thunderstorms to the region. Activity was relatively isolated today, but should increase in coverage and intensity on Wednesday, primarily over the mountains and deserts, possibly over portions of San Diego County as well. Highs will top out in the mid-70s with southerly winds 5-15 mph. Deeper moisture and better dynamics will arrive Wednesday night into Thursday with showers and thunderstorms spreading over much of Southern California. Some storms could become locally strong to severe and produce heavy rain, strong & gusty winds, frequent lightning, and hail; always head indoors when a thunderstorm approaches your area. Cooler through the end of the week as highs drop into the 60s with lows in the 40s. Scattered showers and thunderstorms will continue Friday, decreasing over the weekend. Most of the activity will become more diurnally driven, focused over the mountains and deserts by Saturday and Sunday, decreasing further on Monday. However, a new tropical system in the Eastern Pacific may follow Mario's path and could send additional moisture in our direction around the middle of next week, something to monitor. This precipitation will help to reduce the fire danger across much of the state, as moisture is forecast to reach up into Central and Northern California as well!
