This active snow cycle will continue for at least another week or longer. There are breaks at times with the sun poking through, but overall, its almost a continuous cloudy and snowy pattern with multiple back-to-back storms. Wind and fog may be occasionally problematic. The snow level will lean high on Friday, more moderate on Saturday, then low on Sunday into next week. Cold easterly winds may bring down snow levels in the passes on Friday and again for a time on Saturday.
Friday the snow will increase with snow levels of 5,000-6,000ft, caused by a warm front moving into the NW. That means wet snow or rain on the mid to lower slopes (bummer). It will be challenging on the first day of 2021. Upper slopes may get a few inches of snow during the day.
Overnight Friday into Saturday morning the snow level will drop to 4,000 - 4,500ft with the cold front moving in with increased snowfall. Snowfall totals will vary greatly in this transition. You can expect anywhere from a few inches to more than 10. Of course, you should favor the higher elevations for the most snow (duh).
A new storm will slam the Cascades by lunchtime on Saturday into Sunday morning. The snow level will drop to 2,500 ft with 5-10 new on Sunday and partial clearing. I like Sunday.
There will be a pause with great groomers and off piste on Monday and Tuesday with a new snow storm on Wednesday.
