The Las Vegas Valley Snow Event: What happened? Did we see this coming? Yes and no. We had been seeing very small chances for snow in the valley for a few days, but it wasn’t until Sunday afternoon that the hi-resolution models were consistently indicating that western parts of the valley could see up to 3 inches and up to an inch elsewhere. That’s when the decision was made to issue the Winter Weather Advisory.
