Current GFS sounding at approximately my location (heat dome). I guess these float at 30,000 to 50,000 feet, which is (if I am doing the conversion correctly) at around the 250 to 200hPa pressure range. Looks like almost a cloud layer there right now (the green and red lines almost meet). Also looks like it's awfully windy up there, not sure how much that matters for the balloon (I assume it just gets pushed off by that wind...) 48-57 knot wind (55-66 mph) in that particular range, blowing to the southeast. (not that I am ready to launch anything... but curious to see what these and real soundings look like... maybe launch on a rocket launch day, they have equally limited tolerance for wind, too).
