The second half of May has been great – Mayuary as some people have called it – and it looks like June will start off with a (snow filled) bang!  A small upslope coupled with a jet streak should produce a real snow storm on Tuesday evening through Wednesday (June 1) morning.  Here are the various model forecasts:

14” – RDPS Model

13” – NAM Model

11” – American Model

10” – European Model

8” – Canadian Model

5” – UK Met Model

2” – WRF Model

Any snow this time of year is good to delay the run-off and increase the quality of late spring and early summer skiing.  And fingers’ crossed the more optimistic model solutions come to pass, and we get close to a foot (or more) of snow.  Come on Juneuary!

Retrospective Discussion:

The May storm delivered – the primary storm dumped 14” in Nederland and 1.1” of SWE at the Lake Eldora Snotel.  And then more snow fell over the next several days.  A few thoughts on my prior forecast.  Interestingly, the snow was lighter than I expected.  It also appears to have been predominantly fueled by a jet streak – which I relegated to my third reason for the snow in my forecast (and part of the reason the snow was lighter).  Regardless of my so-so forecast, it was a great storm!  For what it’s worth, the American and Canadian Models overpredicted the storm, and the European and UK Met Models underpredicted the storm.
