NEXT RAIN CHANCE SAN DIEGO: UPDATED SATURDAY 12-1-2018

We will have a quick chance for a shower or two this afternoon and early tonight (4 PM to 1 AM). The chance for rain diminishes tonight and Sunday will be dry and cool. Rain totals will be low: less than 0.1" for coastal/inland areas, and near 0.25" in the mountains. Snow levels will drop as low as 6,000 feet, so the top of Cuyamaca could see a little snow.

I'm watching a bigger system brewing in the Gulf of Alaska. There is a ton of jet stream energy bottled up there (seen on the satellite loop below). Eventually this will organize into a storm system that will dive into our area for next workweek.

I'm expecting showers and isolated downpours to develop Wednesday and persist into early Thursday. The system is still far away, so the forecast will need some fine tuning in the coming days. Regardless, the stormy weather pattern persists, which is great news!

NEXT RAIN CHANCE SAN DIEGO: UPDATED WEDNESDAY 11-28-2018

The next storm system remains on track. You can see it spiraling in the Pacific as it races our way (satellite image below). Scattered light showers will develop tonight and into Thursday morning (5 PM tonight to 11 AM Thursday). Heavier rain will arrive by midday Thursday as the core of the system passes overhead.

Periods of rain and isolated downpours will be possible from 10 AM to 6 PM on Thursday. Isolated thunderstorms will also be possible. Most rain will taper Thursday night, though a stray shower is possible in the mountains into Friday afternoon.

There is a moderate atmospheric river associated with this system, so the rain potential is high, especially if we see thunderstorms. Rain totals will range from 0.5 to 1.5" for coastal and inland areas. Mountain regions will see 1.5 to 3.0".

Snow levels will remain high with this system (above 8,000 feet), so local mountains will not see snow, though there will be accumulations in the San Bernardino Mountains at higher elevations (3 to 6" possible, over 12" at the highest peaks). The Sierra's are going to get pounded with snow, which is great news for the drought! Rain and snow projections are posted below.

We will have another quick chance for rain Saturday afternoon. Snow levels could dip as low as 6,000 feet with this next system, so the very top of Cuyamaca could see some snow.

I'm also watching another big storm heading this way for next Tuesday. I'll bring more updates as it approaches.




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.
