"Hello,
    The Spirit of Knoxville V  (SNOX V) balloon will launch this weekend from Knoxville, TN.  Please visit http://spiritofknoxville.com for more information and live flight tracking.  This will be the last SNOX flight this season, the trans-atlantic jet stream wind is slowing as warm weather arrives.

8PM EDT  Saturday April 5
(0000 UTC April 6)

Thank you,
The Spirit of Knoxville Crew"

I have been looking at jet stream forecasts on this site:

Assuming the balloon launches on schedule and stays at altitude, it will most likely be headed for North Africa or the Iberian Peninsula, even though its initial heading will be more northerly than SNOX IV.
