Powder Day!

Thursday, March 23, 2017 at 6:37 am

Summary:

A storm is pushing through today and colder air has finally arrived. Snow will continue into this afternoon before tapering off this evening.  Today should feature free refills at most Utah resorts.  Another storm will move through on Saturday, with another storm for early next week.

Details:

Rain is falling in the valleys currently with snow in the higher elevations.  Temperatures on the upper mountains have fallen from the mid-30s yesterday afternoon to the mid-20s currently.  That means the snow levels are dropping down below 7000 feet.  Snow should continue throughout the day today before tapering off this evening.  You can see the forecasted evolution of this system on the HRRR simulated radar:

Notice a strong north-south oriented rain and snow band will hang over much of the spine of Utah through the day before falling apart this evening.  That should keep moderate to heavy snow going in the mountains… aka free refills!

A break on Friday before the next system moves in during the day on Saturday.  This is a quick hitting system.  We should see a period of mountain snowfall during the day on Saturday, perhaps lasting through Saturday evening.  I don’t expect much from this storm.  Right now I’d guess 4-8″ for the upper elevations.

Another break on Sunday before a third system pushes in on Monday into Monday night.  Again, not a strong system, at least in the GFS which splits the system and pushes the best energy into southern Utah. The Euro is more consolidated and would have potential for higher amounts in northern Utah as well.  We’ll have to watch to see which model has a better handle on things.  You can see all three of these systems well in the NAEFS ensemble charts from the Univ of Utah:

Nothing major.  But these storms will add up over time and certainly offer some good turns.

Long Range:

The pattern generally should remain active.  Both the EC and GFS have storm system for later next week, around March 31.  Again, probably not anything major, but a good way to close out the month.  The first week of April is anybody’s guess right now, some models have had it continued active, while others have us ridging up again.  We shall see as we get closer.
