I like the looks of the storm on tap for late tonight and tomorrow. It's a pretty good front that is going to usher in the coldest air of the season so far for northern Utah.
We'll start with a look at the GFS forecast valid 0900 UTC 26 October (3 AM MDT Wednesday) when a compact upper-level trough is centered over southeast Oregon and the preceeding cold front is draped across northern Utah. At 700 mb, roughly 10,000 feet or crest hight of the Wasatch Range, there is about a 12˚C (22˚F) temperature contrast across this front, so it's a whopper.
By 1500 UTC (0900 MDT), the trough is over southwest Idaho and the front is draped over Salt Lake City. We will be post-frontal by this time with steady rain on the valley floor and snow intensifying in the mountains. Woo hoo!
