Monday Morning Update......

Sierra is reporting 2-3 inches from the storm yesterday, mostly from the early morning snow bands that came through.

New for today is a piece of energy ahead of the next storm that will pass through tonight. Snowfall is already starting this afternooon from this first wave of moisture. Looking at the models they have .10-.25 inches of liquid over Tahoe with this first wave, with snow ratios tonight reaching 20:1 above 7000 ft. By tomorrow it looks like we could have 1-3 inches at the base, with 2-4+ inches above 7000 ft.

The next storm moves in by tomorrow night into Wednesday. Models are showing .25-.5 inches of liquid over Tahoe with snow ratios getting close to 20:1 again above 7000 ft. Looking for an additional 3-6 inches at the base, with 4-8+ inches above 7000 ft. That would make totals of 4-8 inches at the base, and 5-10+ inches above 7000 ft. by Thursday. Updated totals tomorrow on the second storm.

Storms will continue to try and break through the ridge through the weekend. Looking for another small storm on Friday, and another around Sunday/Monday. These may have snow levels just above lake level around 6500 ft.

Looking at next week it still appears that the ridge will try and block storm activity to our North and may have a bit more success than this week. Meanwhile, the MJO is quickly circling around and should be back in the Western Pacific by next week. We should see the affects on our weather by the week of the 14th with the potential for the return of bigger storms. Stay tuned......BA
