Rayleigh Scattering


If ever asked why the sky is blue, the simple answer "Rayleigh scattering". Named after Lord Rayleigh who published a paper in 1871 explaining how air molecules scatter the blue wavelength of sunlight most effectively, hence why the sky appears blue. One of the many questionably useful things I learned in Meteorology school.

Short Term Forecast

Abundant sunshine and big blue skies are set to continue as the Southwest remains under the influence of high pressure. Gradually warmer afternoon go through a quiet President's Day weekend ahead, right into the holiday on Monday. As the weekend progresses we turn warmer as a Pacific trough develops of California, sending a mild air mass our way. Of note it won't all be cloudless skies as periodic high and mid level clouds stream overhead. 

Extended Forecast

Arizona remains positioned out ahead of the Pacific low into mid next week 2/21. 

I mentioned in the previous discussion that there was hope for a decent storm next week, though all models have backed off on that idea. At this point I don't think we see any snow as weak storm energy finally peels off the Pacific system and lifts over AZ. There is some hopeful news to be had as the main Pacific trough remains in place off southern California beyond mid week and finally breaking inland with hopes for snow around 2/25 and another storm being advertised behind it. Way out, we will have plenty to watch for in future chats. This blog can only be closed with the Allman Brothers Blue Sky, you know how it goes, eat a peach.


NEW: Powder Vision

In addition to our new "Live Snow" data that shows hourly snowfall from nearby weather stations, we built a system to estimate the amount of snow that accumulates on a snow stake camera so that you can track hour-by-hour snowfall for the last 24 hours.

Many ski resorts have snow stake cameras and this allows us to (try to) figure out how much snow falls each hour. We're calling this "Powder Vision".

  1. Go to any ski resort screen in OpenSnow with a snow stake camera.
  2. Tap the "Snow Report" tab.
  3. View the latest snow stake camera snapshot and hour-by-hour snowfall for the last 24 hours.

We have over 60 snow stake cameras available right now and we do our best to add new cams to OpenSnow if we can host them.

Powder Vision and Live Snow are available on and in the OpenSnow app with an All-Access subscription. All-Access includes 10-day snow forecasts, high-resolution weather maps, expert local analysis, custom snow alerts, iOS widgets, and much more.
