NEXT RAIN CHANCE SAN DIEGO: UPDATED SUNDAY 11-25-2018

A strong storm system will bring heavy rain across most of California for the upcoming workweek. A lot of energy is diving down the west side of a large system in the Gulf of Alaska (seen in the satellite loop below). This energy will deepen and head to the West Coast on Wednesday. Computer forecasts have been fairly consistent with this scenario, in fact, the latest European model has this system deeper and stronger.

I'm expecting rain to start in Southern California on Wednesday night. We will then see periods of rain and isolated downpours through the day Thursday. The rain will taper Thursday night into Friday morning. Rain totals should range from 0.5" to 1.0", though some areas in the mountains will get more. Northern California and the Sierras will get some much needed rain (GFS computer forecast of rain totals posted below).

Snow levels will be very high in Southern California, so I'm not expecting accumulations, but you can see on the map below that the Sierras will receive significant amounts of snow from this system.

I'll continue to watch the situation and bring updates as the system approaches.
