Episode narrativeepisode_narrativeAn upper-level trough deepened down the California coast and swung through southern California on the 11th, into the early morning of the 12th. This system brought gusty winds and moderate to locally heavy precipitation to areas over and west of the mountains, as well as a few hundredths of an inch of rain to the upper and lower deserts. Precipitation for most areas west of the mountains ranged from one-tenth to one-half on an inch of rain, though Orange County received more rain overall than San Diego and Riverside Counties. Mountain locations received between one-quarter and three-quarters of an inch of rain. Above 6000 feet, a trace to 2 inches of snow was observed in the San Bernardino Mountains. A couple thunderstorms with damaging winds also occurred near Hemet in Riverside County. ||A deeper upper low developed right behind the last and closed off before diving inland over southern California on the 13th. Instability ahead of the cold front set off several waterspouts and thunderstorms during the afternoon of the 13th. Lightning strikes and wind resulted in roof damage as well as downed power lines trees. The thunderstorms, along with the main area of stratiform rain, brought heavy rainfall amounts over and west of the mountains. Coastal locations received generally between one-third and three-quarters of an inch, locally up to an inch where the heavier thunderstorms passed. Several hundred cloud to ground lightning strikes were observed on the Coastal areas. The valleys of San Diego County and the Inland Empire received between one-third of an inch to 1.5 inches in heavier thunderstorms and along the coastal mountain slopes. Some urban flooding was observed, including a stranded motorist in standing water near Ontario and another truck pulled out of a flooded riverbed near San Bernardino. Some lower mountain locations in San Diego County received up to 2 inches of rainfall. Moderately low snow levels near 4000 feet dropped heavy snow in the mountains as well, especially in the higher elevations of San Bernardino and Riverside Counties. San Diego County received 1 to 5 inches between 4000 and 5000 feet and up to 10 inches near Mt. Laguna. Riverside County was similar with 6 to 10 inches of snow above 5500 feet. San Bernardino County was the big snow winner with several locations reporting 10 to 14 inches above 6000 feet and a max of 16 inches of snow at Arrowbear Lake.
