Cut-off low has been spinning over Southern CA the past couple of days. I didn’t think the rain would make it this far North so the rain yesterday was a bit of a surprise. Now the moisture from that low is sitting over the area as the colder low moves in from the Pacific today. That will keep the rain going.

Tomorrow the cold low moves over NV and stalls out. This will bring with it colder air and lowering snow levels down to 7000 ft., maybe even lower. The storm will now have more moisture to work with as it absorbs the moisture that is already over the area. The thing to watch next is how close the low sits to Tahoe as it is stalled over NV through Thursday. If it is close enough we could see some heavier bands of precip rotate through each day. That could mean several inches of snow at 8000 ft. and higher by Thursday. You may see the first flakes of the season Monday night if the snow level dips down enough.

Temps will stay cool until the low exits so now it looks we stay cool all week. A quick warm-up next weekend as the ridge builds back in. By mid-month we have a pattern change as the ridge flattens and cooler temps move in and the storm door is slightly more open. By the third week of the month the Pac NW should begin to get some cold storms that brush us. BA
