The forecast remains on track for a very wet system to move into Southern California this week, slowly drifting through the area on Saturday, before departing on Sunday. We will be dealing with a cutoff low, so conditions may change, but based on its slower speed, the arrival time has been pushed back to Thursday night into Friday, which also means a slower exit, resulting in higher rainfall totals. Subtropical moisture will continue to stream in across the region on Thursday for considerable high cloud cover, a few sprinkles or light showers are possible during the afternoon with highs in the 50s. Friday and Saturday now appear to bear the brunt of this storm as the low stalls off the Southern California coast, pumping tropical moisture off the Pacific into our area. This will bring rain, possibly heavy at times Friday and Saturday with isolated thunderstorms. Due to the stronger southerly flow and tropical moisture being drawn into this system, the snow level will remain near 10,000 feet through the duration of this storm, possibly falling to around 8,000 feet Saturday, keeping significant accumulations above 9,000 feet. Total rainfall amounts of 1-3 inches are likely in all areas, including coastal, valley, and mountains, with locally 3-6 inches of rain on the lower coastal slopes, which includes our Rim Communities. This will elevate the flood/flash flooding threat, especially below recent burn scars. Daytime temperatures will cool to the 40s over the weekend with lows in the 30s and 40s. South-southwest winds will also accompany this storm, with gusts near 40 mph possible. Showers should taper off on Sunday on the backside of the system ahead of another storm forecast to arrive later Monday into Tuesday. This storm may also start off a little wet, but does have a cooler pool of air to work with, so we could see the snow level fall to around 5,500 feet Monday night or Tuesday morning. How much precipitation is leftover for any snowfall remains to be seen at this time, but a few inches are possible! Stay tuned and always carry tire chains!
