I don't want to get everyone too excited, but the latest GFS forecast has below zero 700-mb (10,000 ft) temperatures at 1800 UTC (1200 MDT) Wednesday.
I'm so desperate for material that I'll just mention this and, given the cold trough, the potential for perhaps seeing a flake or two in the highest elevation.
It's not much to go on, but it's something.
Plus, if my quick skim of the temperatures over the past few months is correct, Wednesday's high @KSLC, which right now looks to be around 70-72ºF, will be the lowest maximum temperature since May 25th, when we hit only 68ºF. Wunderbar!
