A trough off the West Coast will bring cooler temperatures out there today, with gusty west winds at times and rain throughout the day today as low pressure draws tropical moisture across Southern California. Unfortunately, we're looking at a soggy day with showers continuing as highs cool to the 60s, with west winds 10-15 mph. Some instability could spark an isolated thunderstorm, but overcast skies will prevent a lot of widespread instability with the snow level above 14,000 feet. As the moist southwest flow continues into Labor Day, we could see lingering showers, gradually clearing as moisture lifts northeast of the region. A lot of locations have already received around a tenth to a quarter inch of rain today, with additional rainfall amounts of around a quarter inch possible, with localized amounts of one half to one inch, mainly in the mountains and northern area or near any thunderstorms. Showers will taper off by tonight with partly cloudy skies on Labor Day as highs reach the lower to mid-70s. High pressure will return to the Desert Southwest throughout much of next week, setting us up in a late-season monsoon pattern with near-normal temperatures and possible afternoon thundershowers over our mountains and deserts.
