Mainly moderate precipitation with isolated thunderstorms are expected to continue overnight tonight and last until the afternoon hours. Activity will gradually spread southward as we progress through the early morning hours. Showers are expected to taper off by early this evening, though cooler than average daytime highs will last into Saturday before another warming trend returns for Sunday into next week. The best chance for snow will be in the highest elevations, or above 8,000 feet, in the Sierra Nevada from Yosemite to Sequoia NP later this morning through this afternoon. The upper-level trough moves inland into the Great Basin during the evening hours into Saturday. However, winds will ramp up by this afternoon in the Kern County desert, including the Mojave Desert slopes and the desert floor. Gusts at least 45 mph (50-80 percent chance, with the higher end of the range towards the Mojave Desert slopes) are likely to continue in these areas until early Saturday morning. The likelihood for highs in the mid-80`s rises beginning early next week and will last for much of the week. Dry conditions will prevail. The next trough of low pressure arrives by next Friday, which will provide slightly cooler temperatures and a slight chance for another round of showers for much of our forecast area. && .AVIATION...
