December 2nd Update


According to Wikipedia:

1. The wet-bulb temperature is the temperature a parcel of air would have if it were cooled to saturation (100% relative humidity) by the evaporation of water into it, with the latent heat being supplied by the parcel. A wet-bulb thermometer will indicate a temperature close to the true (thermodynamic) wet-bulb temperature.


And that means...?


Put in simple terms, the wet bulb is what our Team Snowmageddon uses to know when they are able to make snow and gives them an idea of the quality of snow that will be produced.  It's calculated by looking at the temperature(f) and humidity level for the day.  Curious to figure out what the current wet bulb is?  Take a look at the attached chart.  Find the current temperature in the left-hand column, and go over to the right until you find the current humidity levels, and that will give you the wet bulb temp!  


Our snowmakers love to see a wet bulb temperature between 14 and 20 for good quality snow production- that means temps should be between 20 and 29, with relatively low humidity levels.  The higher the temperature and humidity, the lower the quality of snow.  On the chart, anything highlighted in blue shows good quality snowmaking conditions, highlighted in purple, it's poor snowmaking conditions, and anything in the dark orange, we're simply not making snow. 


The wet bulb has been in our favor this week, as we've been taking advantage of these cold windows to refresh what we have down and have started onto Phase 3 of our snowmaking plan.  Last night crews were out working on the summit and base area, Easy Street, Gibson, the Alley, Macaroni, Chinstrap and the Beginner Basin area. 


The forecast looks a little warm over the weekend and early next week, but it looks like a cold blast is on its way.


Until next time,
