Storm Day

Saturday, December 24, 2016 at 6:35 am

Summary:

A very moist southwest flow will bring mountain snow and valley rain for most of the day today.  A gradual transition to a northwest flow tonight with colder temperatures and snow levels dropping to valley floors.  White Christmas expected for most of Utah.

Details:

The storm is pushing in currently as expected.  We’ve seen periods of mountain snowfall since yesterday evening.  Accumulations so far have generally been fairly light.  Southern Utah has done alright so far.  7″ reported at Brian head. 5″ for Eagle Point.  In northern Utah, some locations that are favored by SW flow have done well as expected.  4″ for Brighton, Soli, PowMow, DV, PC.  3″ for Snowbasin.  LCC resorts, predictably, are a bit lower at 2″ overnight.  LCC not a typical beneficiary of a SW flow.

This SW flow is ramping up again and it is currently starting to rain at my house on Sandy bench with a temp at 35F.  We should see snow for most of the day today in the mountains with the snow level between 5-6k feet.  Winds will also be a factor today. I don’t think they’ll be too strong, but can’t rule out wind holds on susceptible lifts.

Later this afternoon and evening, a cold front will push through and drop snow levels to valley floors.  There could be a break in the action this evening as the flow switches from SW to NW.  Then, it looks like a burst of snow tomorrow morning to bring us all a very white Christmas.

Here is a look at the copious moisture streaming in today via the HRRR simulated radar for the rest of today.  Also note the possible break in the action this evening, and the widespread change to snow:

Skiing should be fun today, probably getting better as the day goes on.  No need to rush for first tracks today.

Christmas Day will be a powder day for all.  But perhaps you should sacrifice this one to spend time with your family at home.  Total accumulations for this storm…  I’m sticking with 1-2 FEET in the mountains.  Certainly could be pockets of higher amounts.  Highest amounts likely for Northern Wasatch and Southern Utah as well as the Uintas.  This could be one of the rare storms that the Cottonwoods aren’t the big winners.

Long Range:

A break Monday and Tuesday, then a very weak storm for Wednesday.  This kinda looks like the weak storm we had this past Wednesday.  The far north could get a couple inches, but most of us will just see a few light snow showers.

We then ridge up for later in the week.  Euro keeps us dry into the New Year.  GFS tries to drop a system down the backside of the ridge into the area for New Year’s Eve.  We’ll have to wait and see.
