Earth Day: So What?
Sorry to be a cynic, but I don't think Earth Day has accomplished much. It should be retired. I'm not against what it stands for in any way, shape, or form, but we spend too much time discussing simple things that we can do to reduce our carbon footprint. Youngsters out there – you can think much bigger and do what my generation couldn't.
Passing of Prince
Although I never was a big fan, I came of age when Prince truly was a mega star and we tip the hat to him today for Purple Rain. It's always great to see hydrometeors referenced in album and movie titles.
Wind and Dust?
We should see some south winds today and possibly some blowing dust around the state. The frontal timing isn't quite right for a really big blow in the valleys as ideally you want the strongest flow to be phased with the peak in afternoon temperatures. Instead, the maximum low-level flow, at least in the 0600 UTC NAM forecast, comes in later this evening and overnight as illustrated by the time-height section below.
Nevertheless, the predicted flow for today is sufficient to support the NWS forecast of 25-35 mph south winds with gusts in excess of 45 for many of the valleys and basins of western Utah.
Closing Weekend Dumpage
Forecasts for mountain precipitation during and following the frontal passage have been fairly erratic, but we are going to get some of the white stuff. The 0600 UTC NAM generates nearly an inch of water and 9 inches of snow at Alta from Saturday morning to Sunday morning. Cream on crust seems likely for closing day at Alta. If we get an inch of water or more, the skiing might even be decent. Temperatures are such that most of this snow will be high density, but in late April, beggars can't be choosers.
