Speaking of snow...does it get any "better" than this?

This is the NWS Reno, NV forecast for Truckee, California. Truckee is north of Lake Tahoe and is 5829 feet above sea level. Expected snowfall before sunset this evening is 19-25". An additional 8-12" is possible tonight. The snowstorm will continue well into the weekend and snow is expected well into next week. The NWS Reno has their own weather camera online and a one hour loop option. This could be interesting to peek at today. Cold air from a low in the Gulf of Alaska is combining with subtropical moisture which will produce some incredible snow accumulations, especially in high elevations. Three to five feet of snow is expected in areas above 7000 feet. Accumulations of over seven feet are expected along the Sierra Crest. There is the potential for as much as 10 feet of new snow accumulation in some areas. Winds on the Sierra Ridges will be sustained at 80 to 100 miles per hour with gusts to 150 miles per hour this afternoon and evening.

Here are a few excerpts from the NWS Reno forecast discussion:
"Satellite imagery shows an impressive low pressure area nearing 130w riding a strong jet stream. Satellite derived jet level winds are as high as 235 kts!!!! WV/infrared Sat imagery shows an impressive baroclinic Leaf now inside 130w at around 35n. This feature is pointed directly at the Sierra and western Nevada with current rainfall rates estimated close to 1 inch per hour. Extremely heavy snowfall with wind gusts up to 60 miles per hour or more will make any travel nearly impossible and life threatening. In addition...ridge gusts of up to 200 miles per hour will occur. As day shift mentioned... snowfall rates of 6 inches per hour are likely for a few hours...and may even be heavier at times. Total snow in the Sierra will be several feet..."
