A follow-up storm from the Nov 4th storm reached Southern California early morning. The initial cold front had less precipitation (0.15) than the previous storm.This storm took a more inland approach (known as an inside slider) but temps were similar to the preceeeding storm. In the evening, a thunderstorm complex moved through Riverside County (NW to SE) with occasional lighting and moderate rain (0.17) bringing the storm total close to the totals received a few days earlier. |

Cut-off low originating from Alaska migrated all the way to just south of the CA-MX border before shifting east. The eastery shift along with tapping of some tropical moisture resulted in 1/3 of an inch for HCR. Further south in San Diego most locations received over an inch of rain. This storm had the unique distinction of spreading moisture from South to North. This is extremely rare for a mid-lattitude cyclone. |
