I like that cluster of trees on the far right of the photo, right in the middle, top to bottom. They don't seem to be the tallest trees, so maybe the lightning will go somewhere else. I can't tell where west is in the photo, but I would want to be on the lee side, on the edge of the trees for some protection from the wind. Then, you want to be sure you don't have any metal objects near you (pack frame?). That's one reason I love my carbon fiber trekking poles for supporting my various tents. I'm not sure how I would cook my dinner though (metal stove and canister, titanium pot). Maybe just wait the storm out, or else eat a Pro Meal Bar, and call that good?
Randy, what many of the posters maybe don't know is that our Colorado afternoon thunder/lightning storms are usually intense, but brief. It's the lightning that we have to worry about, not so much the rain. Mags knows what I mean.
