At Black Rock the winds can turn a great launch into a dust eating, zero visibility, canopy blown to Winnemucca mess.  On any given day mix in an approaching front and a dab of active Jet Stream and you have a blow out. 

Generally winds come up in the afternoon due to heating and thunder cloud formations. The Jack Pot for great flying is a big blocking high pressure parked on top of Gerlach. That is truly a thing of beauty.

Typically Rocket flights are in the 3- 20 K range so winds in this range are of interest. Of course there are those altitude junkies that have managed to push an airframe off this chart. Trivia: A mallard duck was struck by a airliner at 21,000 ft over the Nevada desert and some species have been observed migrating at 29, 000 FT.

36,000 FT

This is the altitude where the Jet Stream can be quite active.

The Jet Stream is a pretty good indication of how the winds will be at Black Rock. I have been keeping track of this for some years now and found it to be good rule of thumb. So before you head out next time check out the 3 day Jet Stream forecast and compare for yourself.
