How can the ground level wind direction be so different from the winds aloft?

A front is a merely collection of like weather moving together in one direction. The front as a whole was moving in a direction from west to east. It will always move from west to east because they are guided by the jet streams, which themselves are guided by the earth's rotation. This front was a low pressure area, winds in low pressure blow counter-clockwise. Just like a hurricane when they say the worse side is the right front side as it moves ashore.
We are now in high pressure, current pressure is 30.20 at 9:30pm, normal is 29.92, a high is always clear, cool and windy, which is what we have. We should also switch to clockwise wind since the front has passed and we are now north of the front.
