Yes, wind is a pain in the butt when practicing especially euro-techniques, but generally all of the time anyway. If you're adamant about sticking to it in those conditions, my primary advice would be to keep your rod tip as low to the water as you can to minimize the impact of the wind, while doing your best to maintain contact with your flies. You could also try tying on heavier flies than normal to help you maintain contact, albeit you may lose more. The V-worm is a good flies for windy days since it is both heavy and snag resistant. At least you'll be in the zone.
Wind sucks, plain and simple. It's going to affect you if you're indicator nymphing as well, but maybe to a slightly lesser degree. The wind gusting can and will mess up your drifts. I'm sure others will chime in with their thoughts.
Don't forget, sometimes one section of river may be windier than others. Seek out the ess curves where the terrain may give you some relief from the wind. This tactic recently paid off for me on the Cattauraugus, where you can be either in a wind tunnel or relative calm in the lee of a cliff.
Plan B: bring beer and throw in a lipper, wait till it calms down, if possible.
