Sierra Snow Diary


- 2020/2021 -
5/2/21: For some unknown reason, Sonora Pass isn't open yet, but you can drive up to Tioga from the east. Warm weather and the below-average snowpack means that snow is best above 9000', and even there coverage and depth aren't great. So get your last turns in soon and have a good summer!

4/26/21: Today was a bit of a powder day, with a half foot or more of fresh falling through last night. Warm days ahead will bring back the corn though, very soon. Good spring skiing remains at higher locations, but not with a lot of depth.

4/19/21: Mostly sunny warm conditions continue (with some precip moving through briefly midweek). But then, this past week, a storm band that I predicted to be "minor" dropped a surprising amount of snow, mostly just a few inches, but up to a foot in certain areas!

4/12/21: Another mostly warm sunny week ahead (with some minor late-day precip possible here or there). Coverage is suffering on some aspects (and most ski resorts are closed or will close this coming weekend). There's still some great corn snow out there, though; this is a below-average season so grab it before it's gone.

4/5/21: Yet another mostly sunny week with no significant precip. Get out there for some fine spring skiing!

3/29/21: And it's another sunny warm week ahead, though windy early in the week and going into the weekend.

3/22/21: Spring has begun. Last week brought a foot or so of new snow. This week, it's going to be mostly sunny and warmer, with a couple bits of unsettled weather and maybe minor precip.

3/15/21: Predictions for the past week were exceeded, with some areas getting 2-3 feet of new snow (through today as the latest wave winds down). Coming week: It's staying cool, and a foot or more of new snow arrives by the weekend.

3/8/21: We just got a several inches refresher. This week will be cool and unsettled, with a foot or so of new snow mostly around mid-week.

3/1/21: Dry for the past week, and dry for the coming week aside from probably some not-major storm activity on the weekend.

2/22/21: Some few-inches storms came through in the last few days (some higher areas may have accumulated nearly a foot). The coming week will be cool and dry, except for some possible very minor precip late in the week.

2/15/21: The past several days (through today) adds up to 2 feet of snow. Increasingly unsettled weather this week will lead up to a storm around Friday, adding another half-foot or more. It's a below-average but decent snowpack, so get out and enjoy.

2/8/21: Up to a foot of fresh early in the past week. Increasingly unsettled weather this week, with maybe another foot or so in the storm that goes into the weekend.

2/1/21: Last week brought this season's first truly major storms, adding 5 to 7 feet (I heard 8' for Mammoth) to what was previously not great coverage. We're still below average, but what an amazing difference. Another foot or more arriving early this week.

1/25/21: The dry spell is over, with most of a foot in some areas added in the past few days. The big stuff finally arrives later this week, with several feet of snow likely by a week from now.

1/18/21: It's been dry and warm for the past week, and will be dry and cooler the coming week, with a not major storm arriving going into the weekend. Coverage is starting to suffer, so more snow is definitely needed.

1/11/21: Following the up-to-a-foot wet storm a week ago (and minor rain/snow a few days ago), we're in another dry spell now, with no significant precip expected for the next week or so (California's southern Cascades will see some snow mid-week).

1/4/21: The past week dropped a few inches here and a few more inches there, adding up to a half foot or more in some places. The storm moving in now should add up to another foot. Then, mostly clear, with some possible snow (inches) towards the weekend.

12/28/20: About a foot added, in some areas, in the last few days; the snowpack is still on the thin side, but it's coming along. Coming up: Unsettled with a bit of snow mid-week, with a possibility of storm action on the weekend.

12/21/20: Up to a foot fell middle of last week; less than half that in the north Tahoe and Donner areas. This week will mostly be dry, with some light showers on Tuesday, and a probably not major storm around the weekend. The holidays scoop: There is coverage, and resorts (downhill and XC) are open (with social distancing, and purchase and general travel restrictions), though with less than great coverage. Backcountry is happening as well, though quality and base depth will be a mixed bag.

12/14/20: About a foot of badly needed snow just landed in the past 24 hours, so once again, there is a base for future storms to build on. Another foot-or-so storm is expected later this week. Resorts are mostly open, and some backcountry should work, but be aware of Covid travel prohibitions.

12/7/20: Our December dry spell continues, with a thin snowpack. Look for adequate coverage at resorts that are keeping snow on groomed slopes well maintained, better yet with snowmaking.

11/30/20: That decent start for a base a week or two ago needs more on top of it, but unfortunately it's clear weather through next weekend.

11/23/20: We got some snow in the past week, adding up to a couple of feet in some higher areas, a good starting base, and it's been adequate to open resorts and for some careful backcountry runs. It's dry weather ahead, though.
