It might come in a bit less that what is being predicted but once you get within a day or two of these snow events they generally get it right. I wouldn't trust the 7-day forecast nearly as much.
I'll post again when I-80 closes.
Here's the forecast for the I-80 summit... breaking 30" of accumulation in a couple different 12-hour periods is big big snowfall. On the high end this is showing 11+ FEET!?

I-80 crosses the Sierra Nevada crest at Donner Summit (also known as Euer Saddle) at an elevation of 7,239 feet (2,206 m) westbound and 7,227 feet (2,203 m) eastbound. The Donner Summit Rest Area is located at this point.[23][24] The summit is located in Nevada County, California. The pass is generally open year-round; it is plowed in winter but may temporarily close during the worst snowstorms.
