The Jetstream along with surface wind will both have an impact on your viewing conditions. Surface wind will obviously affect your tracking as wind gusts might move your telescope unless it is protected. The high altitude wind will create turbulence that will again show in your image.

You can very easily build a composite map combining surface Wind (10m) and Jetstream (300hPa) on CFN by going to the map section then selecting Wind (10m) as a base layer and Jetstream (300hPa) as an overlay (padlock). Afterwards you can select your location and time to view your local conditions.

The optimal areas will appear as darker shades of blues with very short overlapping wind vectors.
