Snowpack at Mammoth Pass (9,300 ft): 0.36″ of water, 33% of median for the date.

How this is made: amounts and ranges from the ECMWF, AIFS, GFS and Canadian ensembles (the Canadian at a quarter weight; plus NCEP's REFS for the first 2½ days), with snow worked out for this elevation; temperatures from the National Weather Service for days 1–7, shifted to this elevation. Totals are the members' median, so half get more and half less; the days show when it falls and add up to the total, and a day's % chance is the share of members with measurable precip. The charts show NWS's own amounts beside the models (◇). See the raw models

Snow and precipitation (liquid: rain plus melted snow) are typical amounts: each day's share of the median total across the models' members, so half the members get more and half less, with the likely range beneath; blue and green mark measurable snow and precipitation, amber wind of 25 mph or more. Under each high and low, the day's average dew point and its range of relative humidity (National Weather Service, then the ECMWF and GFS models past its forecast). Forecasts combine the National Weather Service with the ECMWF, AIFS, GFS and Canadian ensembles.
