Yesterday, NOAA had a Winter Storm Watch issued for the southern Sierra and not the northern Sierra.  Today, they’ve extended that Winter Storm Watch to include the northern Sierra and Lake Tahoe.  The watch is in effect from Friday afternoon until Saturday morning.

Snow levels are going to be high and this storm is going to show up with a lot of wind and rain before turning to snow.

1-2 feet of snow is forecast above 8,000-feet, 6-12″ forecast above 7,000-feet, 6″ forecast below 7,000-feet.

Saturday will likely be a day with upper mountains closed and lower mountains very soggy.  Sunday, though, could be spectacular up high.  Granite Chief?  Palisades?  Mt. Rose?  boom.
