The resultant wind direction, in theory, is due to two forces (far from the ground) 1) the difference in pressure between two areas (the gradient pressure force) 2) the Coriolis force due to the rotation of the Earth. The Coriolis force on the Norther emisphere turns the wind direction to the right, until it is balanced by the gradient pressure force (always directed from high to low areas). So in the end, winds do not blow from high to low but in a normal direction to the gradient pressure force. If you put your back to the wind, the low pressure area is to your left, and the high pressure area to your right. You can find more information (and a better explanation) on any ATPL meteorology books.
