The balloon is cruising at 107,000 ft which is just above the 10 mb
surface.  There is some but only a weak relationship to the jet stream
winds which are typically 200-300 mb (30-38,000 ft).

There are not many resources for winds near 100,000 ft, but I have
some charts at http://nstar.org/GFS which are updated manually.
