| episode_narrative | An amplified ridge over the eastern Pacific allowed a few upper-level short wave troughs to move over the region from the 11th through the 13th, resulting in strong, gusty winds and widespread light rain. These passing troughs culminated in a closed upper-level low over San Diego the 14th through the 16th. This cold, closed low dropped south and inland bringing widespread rain and heavy mountain snow to the CWA. |On the 14th, San Diego County received the highest rain amounts due to instability showers in the northwest flow behind the shortwave trough axis. Amounts were generally between 0.15 and 0.50 inches of rain, with around three-quarters of an inch on the coastal mountain slopes. Areas above 3500 feet received 2 to 4 inches of snow, with up to 5 inches at 5000 feet. The Riverside County Mountains received 1 to 2 inches of snow above 5000 feet, while the San Bernardino County Mountains fared somewhat better with a trace to 3 inches above 4000 feet and up to 6 inches around 7000 feet. |The system stalled out over San Diego for the 15th and 16th. The snow level dropped to around 2800 feet that day. The San Bernardino County Mountains came in with a trace up to 5 inches in the range from 3000 to 6000 feet and generally 6 to 8 inches above 7000 feet, with locally higher amounts of 12 to 14 inches in places such as Idyllwild and Big Bear City. The Riverside County Mountains had higher amounts with 10 to 14 inches above 5000 feet and up to 20 inches around 8000 feet.The San Diego County Mountains received 3 to 6 inches above 3500 feet, including 4 inches of snow in Julian which closed schools in that city on the 13th and 15th. Chain control was required in most mountain locations across the area above 3500 feet. California Highway Patrol even closed Interstate 8 near Pine Valley due to the snow and icy conditions. Rainfall was generally moderate and locally heavy ranging from 0.2 to 0.5 inches in the coast and valley locations, with locally heavier amounts up to 0.8 inches on the mountain slopes. Isolated thunderstorms with accumulating small hail and even a few funnel clouds also occurred in the cold, unstable air behind the front during the morning and early afternoon of the 15th. |
