Snow levels will rise from around 4500 feet early this morning to 6000 to 6500 feet around noon, 7000 to 7500 by late this afternoon, and to around 8000 feet by Thursday morning. Lighter precipitation will spread southeastward across the area early this morning, becoming more widespread from the coast to the mountains for late this morning through tonight. For Orange and southwestern San Bernardino Counties through tonight, rainfall and liquid-equivalent above the snow level is expected to range from one-third to two-thirds of an inch near the coast to 0.75 to 1.25 inches in the mountains with snowfall of 2 inches above 6000 to 6500 feet and 3 to 6 inches above 8000 feet. For San Diego County, rainfall through tonight is expected to range from one-half to one inch near the coast to 1.5 to 2.5 inches in the mountains. For Thursday and Thursday night, heavier precipitation will spread southeastward across the area with additional rainfall and liquid-equivalent above the snow level for Orange and southwest San Bernardino Counties from around 1.5 inch near the coast to 3 to 5 inches in the mountains with local amounts to around 6 inches. For northern San Diego County and western Riverside Counties, amounts are expected to range from 1 to 1.5 inches near the coast to 2 to 4 inches in the mountains with amounts across southern San Diego County from around 0.75 inch near the coast to around 1.5 inches in the mountains. A snow level around 8000 feet on Thursday will lower to around 6500 to 7000 feet for early Friday morning. For today through Friday night, rainfall and liquid-equivalent above the snow level for Orange, southwestern San Bernardino, western Riverside, and northern San Diego Counties is expected to range from 2 to 2.5 inches near the coast to 4 to 7 inches in the mountains with local amounts exceeding 8 inches. Amounts will decrease from north to south across San Diego County with amounts across southern San Diego County ranging from around 1 inch near the coast to 2 inches in the mountains. For the lower deserts, amounts are expected to range from around one-quarter inch for locations bordering Imperial County to around 1 inch for the northern Coachella Valley. For high desert areas, amounts are expected to range from one-half to one inch farther inland from the mountains to 1 to 2 inches on the foothills near the desert slopes of the mountains. Additional snowfall could be as much as 1 to 2 feet above 8000 to 8500 feet with 4 to 8 inches from 6500 to 7500 feet. For Thursday and Thursday night, there could be hourly rainfall as much as 0.75 to 1 inch on the coastal slopes of the mountains with the most likely time for heavier rainfall rates on Thursday evening when there is also a slight chance of thunderstorms. Both the San Diego River at Fashion Valley and the Santa Margarita River at Ysidora are forecast to reach Monitor Stage late Thursday night into Friday morning, with only an 8% chance of the San Diego River reaching Minor Flood Stage. $$ 17
