Mountain waves at KCOS/KFLY

A nice visualisation is something we all used to use before BLIPMAPS.
The old Java FSL sounding plots are now available as HTML, so if you're allergic to coffee you can still use them.

Choose KCOS (or anywhere you want to fly), Latest, and a number of hours (12?) then Load.
As noted by Dan and others you're looking for wind increasing with altitude, not varying much in direction from perpendicular to the ridge. There will likely be a temperature inversion down low. Winds below that will be quite different, not really a factor in the wave but may mean easier ground handling.

Does east of the Front Range get low altitude rotor without wave conditions? Or does that only happen between two ridges with a height differential?

At the old Black Forest another pilot came back from his orientation flight reporting:
Almost instantly, the horizon was going up and down, and the towplane was inverted relative to the glider. They both completed the roll on tow, and continued to the wave.

Rotor happens everywhere. Wave is optional.

What happened to Black Forest glider port. I remember the adds in Soaring years ago

Bought up by a developer and shut down. The club split into the new
Black Forest Soaring Society at Kelly Air Park (CO15) east of Larkspur,
and Colorado Soaring Association at Owl Canyon Glider Port north of
Wellington, CO.

BTW, the old Black Forest had not seen any development up until I left
there in 2001. The grass runway was still visible.

....rode by on CO-24 this past spring after dusk; too dark to see anything. The
vehicle consensus was there may by now be houses on the southern half of the
property...which is what Google Earth shows in a shot dated 10/22/2011.
