Very warm air is currently over the region with temperatures today likely to reach record levels for many locations for this date. Rain showers will turn to snow in the high elevations as a cold front pushes through later on Friday. Saturday could be a decent powder day. Clearing for late in the weekend into early next week.
The good news is that we have another storm pushing into the region. The bad news is that temperatures are very warm. The ugly news is that means rain will fall perhaps all the way up to 9,000 feet (maybe higher) before snow levels fall during the day on Friday. This is all thanks to another atmospheric river event pounding California with moisture being pulled from Hawaii:

Today we will see periodic rain showers and temperatures will be extremely warm. Perhaps mid-60s in the valleys (which would be record highs) and up into the 40s in the mountains. Snow levels could rise to 9,000 feet or above today into tonight. Currently the temperature at 9,600′ at Alta-Collins is a balmy 35F, and it’s been as high as 37F already this morning.
The main storm pushes in on Friday with snow levels dropping a touch down to maybe 8000-8500 feet. If you’re planning to ski Friday, expect rain at the base in the morning. Might be a good day to get creative with a trash bag as your outer shell as it will be a wet day to be on the slopes. Snow levels will fall through the day and really crash late Friday evening. However, by that time, the best precip could be over. Hoping to get at least a few inches of fluff on top.
Accumulations by Saturday… 6-12″ of extremely dense snow for elevations above 9,000 feet. Lesser amounts for the lower elevations. As I’ve stated previously, it’s not a good storm by typical ski standards, but Friday afternoon and Saturday morning could still be fun!
We will clear out fully on Sunday with warming conditions again and dry weather for the first half of next week.
Active weather will take aim at California later next week. Initially, systems may have trouble maintaining strength as they cross the Great Basin. We could see a weak-ish system around Friday the 17th, and perhaps a stronger storm for around Monday the 20th. These storms do appear to be at least a little bit colder than current storms.
