Lake Tahoe resorts reported 4-8in of snow overnight, but as my boy Hatchett (La Vida is his author name) said, Squaw got at least a foot and with prime wind deposited areas, 2 feet of fresh powder was to be shredded. The NWS under forecasted this event. They were calling for around an inch or so of snow around Tahoe. As we have seen in the past and especially this year, if the temperature range -14C to -20C is in an area with the most lifting, larger amounts of snow will fall.
This temperature region is prime for dendrite formation (snowflakes) and when upward motion is maximized in and around this temperature layer, higher amounts of snowfall can occur. Last night, a shortwave moved through aided by the left exit region of the 300mb jet to help provide some more lifting. The 12z Reno sounding shows a very saturated and unstable vertical profile while the radar images had dBZ returns between 20-35. No doubt some weak convection and upslope flow aided in the higher snowfall amounts.
To make a long story short, I should have went skiing today and I will go skiing tomorrow, haha.
