Unless there’s an absolute blizzard, CALTRANS does a great job of keeping I-80 clear over the sierras (Sacramento, Bay Area). And the airport is similarly managed. Planes safely land in all kinds of conditions and weather. So, even though I’d feel comfortable flying in/out of Reno International any time of year (and have), I’m still shooting for nicer weather months, so fear not. It should be a great event.
