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.
