In the northern hemisphere, the winds aloft blow parallel to the isobars and the pressure gradient, which means they flow from high to low pressure. If the upper-level winds are blowing from the south, it indicates that the low-pressure trough is to the west, as the winds are moving clockwise around the low-pressure system due to the Coriolis effect.
