Monday – Tuesday:
We will see some clouds Monday from a system off the coast. We will also see ridgetop wind gusts increase to 50+ mph during the afternoon. That weather continues into Tuesday with slightly cooler temps in the 30s for highs on the upper mountain. Ridgetop gusts could peak around 60+ mph in the morning and then coming down some through the afternoon.
A small amount of moisture will try to stream into the Sierra by Tuesday into Tuesday night. Amounts look pretty meager. We could see scattered showers with snow levels around 7000 ft. or just above. That means rain showers for the base, and maybe a coating to an inch of snow up top by Wednesday morning.
For Wednesday, high pressure builds back in briefly with mostly sunny skies expected. Highs in the 30s & 40s.
Thursday – Friday System:
The next storm will try to push into northern/central CA by Thursday afternoon into Thursday night, and then clearing out Friday. We have a lot of discrepancies still with the details of this system as it is trying to push over high pressure off the coast and under high pressure farther north.
We could see rain/snow showers by Thursday afternoon with snow levels around 6000-6500 ft. (just above the base) to start. Then steadier snow possible Thursday night with snow levels falling below the base. Showers could linger into Friday morning before clearing.
Initial estimates for snowfall are for 1-4 inches at the base, and 3-7 inches on the mountain.
Another system will try to push into northern/central CA Saturday afternoon into Sunday morning. This system will have the same issues as the first, but it could be slightly colder. We will continue to watch the trend on both systems over the next few days and will fine-tune the details as we get closer.
