A small storm system will bring rain to Northern California tomorrow. Unfortunately, this system won't bring any rain into our area. I'm keeping a closer eye in the Gulf of Alaska, where the upper atmosphere is becoming energized. Eventually a series of systems will dive out of this region and bring us our next chance for rain.
Showers should develop Sunday night (12/22) and persist on-and-off through Monday (12/23). Isolated showers could linger into Tuesday (12/24) as well. This system doesn't look cold, so snow levels will be moderately high.
The second wave of energy moves in late Christmas Day. Right now it looks like the heaviest rain will move in Wednesday night (12/25) and into Thursday (12/26). This will be a colder system, so some local mountains could get some snow.
Obviously this is still far away, so there could be some changes to the timing of the rainfall. I'll have more updates in the coming days. This pattern could persist into New Year's.
