Cold Surge Coming

 There's a pretty good cold surge expected to push into northern Utah later this week.  By Friday afternoon, yesterday's high of 88˚F will be long forgotten.  

Below is the GFS forecast for 2100 UTC (3 PM MDT) Friday showing a short-wave trough moving through northern Utah with 700-mb (10,000 ft) temperatures near -8˚C.  

The GFS-derived Little Cottonwood forecast shows temperatures on Mt. Baldy dropping from 43˚F tomorrow afternoon to 13˚F Friday morning.  Your Friday morning dawn patrol will feature slide-for-life conditions in the Baldy Chutes.  

Right now, the system looks fairly dry.  The GFS produces only 0.13" of water equivalent with it on Friday at Alta.  There are a few members of NAEFS (11 out of 52) that produce more than 5" of snow at Alta Collins, but most are under 2".  

Unless a low-probability snowfall occurs, the best recreation options later this week and weekend are probably at lower elevations.
