Dribs, Drabs, Cold Front, Ridge

I so look forward to the day I can say a big dump is coming, but that day is not today.  We remain on the southern periphery of the storm track and an impressive plume of moisture that will be bringing the goods to our friends in the Tetons and others to the north, but will only give us some dribs and drabs through tomorrow night when an upper-level trough and a healthy push of cold air surge into Utah. 

We'll get some snow, but the models presently call for most of the action to remain to the north.  Thus, I don't see the this being the big dump that we want and need.  Sharpening the edges on the rock skis is probably a better idea than mounting up those new powder skis.  

Then, a ridge builds in for another extended visit.  

Alta reports a cumulative season snow total of 92", plus the couple of inches fell last night and today.  With luck, we might get to 100" for New Years.  Might.


  1. Tomorrow's storm looks interesting in terms of its dynamics (although a bit to the north of us, of course). The cold core trough is moving eastward very rapidly (80+ knots near the 500-mb level), which means strong cold advection at mid/upper levels may precede the surface cold front in many areas. With the mild and moist lower level atmosphere, I think there may be thunderstorm development along the front in Idaho and perhaps along the northern border of Utah.

  2. It's a shame we don't have the DOW... it would be a good weekend to take it to Jackson.

  3. I noticed that the theta-e time height for Boise shows a good portion of the baroclinic zone tilted forward with height around 00-06Z tomorrow, which could be a recipe for some good convection in this CAA zone.

  4. Yeah, we need a DOW. Weenie readers - just a cool $2 mil plus maintenance and you can support our powder seeking habits!
