A friend of mine, Sean Jones, who is a professional skydiver, gave me this website for showing the upper wind patterns (magnitude, direction) at different elevation intervals. I’m told this website is popular with hot air balloonists.
I think the closest weather station to the MTA is Mojave, California. It could be a useful tool to predict which way our rockets are landing.
Also, someone mentioned the Friends of Amateur Rocketry (F.A.R.) just to our south at the MTA has a personal weather station.
Cantil, California 35.347 North, 117.808 West

It should pop up if you enter the weather station ID: KCACANTI2
