Showers will increase in the mountains today ahead of a Pacific low pressure system that will bring more widespread and heavier precipitation for tonight and Thursday. The most widespread and heaviest precipitation is expected with the cold front as it moves southward across the area for late tonight into Thursday evening. Showers will continue through the afternoon along with a slight chance of thunderstorms. Through Thursday night, rainfall and liquid-eqivalent above the snow level is expected to range from around one inch near the coast to 2 to 3 inches in the mountains with local amounts to around 5 inches on the coastal slopes of the San Bernardino County mountains. For the Apple and Lucerne Valleys, one-half to one inch is expected with one-quarter to one-half inch for the lower deserts. Rainfall rates of 0.50 to 0.75 inch per hour are expected during the periods of heavier precipitation, locally up to one inch per hour possible in the mountains below the snow level and where thunderstorms develop. A snow level around 6000 feet through tonight, will lower to 4000 feet by Thursday afternoon and 3500 feet by late Thursday evening with snowfall of 4 to 8 inches from 5000 to 6000 feet, 8 to 14 inches from 6000 to 7000 feet, with local snowfall of 24 inches or more on the higher peaks above 8000 feet. A weaker weather system moving inland to the north is expected to bring another round of showers for Friday afternoon and evening but with less totals, around one-tenth inch near the coast to one-quarter inch in the mountains. $$ 17
