Park Rangers have completed the March 1 snow surveys. The water content of the snowpack in the Tuolumne drainage is 29% of average and in the Merced drainage is 26% of average. The courses at the lower elevations (7000' and below) are particularly dry-about 16% of average. About three quarters of the courses were measured before last week's storm, however, so the actual March 1 percentages are slightly higher.

All the February storms had high snow levels with jetstream at level Pacific latitudes pushing storms due west . Lower elevations are unusually lacking in any snow. Have gone skiing twice the last few weeks and there is almost no snow below 6k even in shady areas. Caught a rumour that out beyond a week there are signs of the jet stream coming down from the north.

NOAA Reno:

An upper level trough across the eastern pacific will provide a
Chance for rain and high sierra snowfall sunday into monday next
Week. Recent model guidance is in reasonable agreement in drawing
A subtropical moisture plume across northern california sunday but
Have trended slower with the precipitation onset. Main changes to
The extended forecast were to decrease pops sunday and increase
Pops monday to reflect the delay. Precipitation will begin as
Early as sunday morning mainly north of the tahoe basin into
Lassen county. This looks to be another warm system with snow
Levels around 8500 feet sunday falling to 7500 on monday as a jet
And surface front move through the sierra and western nevada. This
Will allow precipitation to spill over into western nevada during
The day on monday as the front passes. Still some modest
Discrepancies in resolving the shortwave`s progression amongst
Deterministic guidance and put forecaster confidence at medium
With this system.

Showers diminish through monday evening with lower forecaster
Confidence heading into next week wednesday. Medium range models
Agree on a drier period through midweek but still have substantial
Differences beginning tuesday. The gfs shows a shortwave cutting
Across northern nevada while the ec builds a shortwave ridge. Have
Sided towards the ec as several gefs members keep the track of the
Shortwave further north and have keep us dry in the forecast as a
Result. Overall, looking for mild temperatures in the extended
Forecast with highs in the upper 60s by sunday across western
Nevada and back into the upper 50s tuesday after the passage of
The front.
