Narrative:

Winds were reported as calm. Approximately 100 ft AGL, above the tree line, I apparently had some type of windshear and turbulence out of the east or southeast. It caused my plane to bank to the right and pushed me past the control tower before I could correct for it. I passed 300-400 ft from the sgf control tower. I immediately initiated a maximum performance climb to gain altitude.
