Dribs and Drabs = Deep Powder

Several days ago, I thought the the period through this weekend looked sort of ho hum (see The Week Ahead).  The models were putting out some fairly modest snowfall amounts, equating to perhaps half of what we might expect climatologically.  Even most of the members of the the normally jacked NAEFS ensemble were keeping snofall totals near or below 15 inches through this morning (12Z 28 January).   

Fast-forward to this morning and let's see how things have turned out.  Per the Alta snowfall history, 10" on the 24th, 1" on the 25th, and 9" on the 27th.  Per the Alta-Collins automated snow depth sensor, another 3" yesterday and 10" overnight.  I'm not sure what period the Alta snow history covers each day to splice these together, but we're well above the projections of nearly all of the NAEFSforecast members, except one plucky one that was up around 30" by 12Z on the 28th.  

So, dribs and drabs in this case means deep powder.  What a season!     

Perhaps I should issue another pessimistic forecast as it seems to be working.

  1. How much water in that 33" of snow? How does that compare to the forecasts?
