Forecast Summary 

Heavy snow and Winter Storm Warnings for the Wasatch Mountains of Utah today, until it exits around 5 pm, as the storm moves through the state on its way to Colorado, this morning.  Colorado will have light snowfall today with modest amounts, with slightly better snowfall rates this evening.  

Meanwhile, back on the west coast, the Tahoe storm has exited to the north and is moving through the Cascades.  Snow levels are again in play for lower elevations with a wintery mix possible for the northern Cascade resorts.

The next storm system is off the coast and churning towards the Lake, with yet another example of this year’s new pattern.  Below are GIFs of the surface (MSLP) and the 500 millibar level, that is about halfway up in the atmosphere where most of the energy is.  These animations show the motion and new track, to this year’s pattern.  In the MSLP, watch the Low’s circle the drain in the Gulf of Alaska.
