Air in the warm region rises which causes the isobars to "spread apart". A horizontal pressure gradient in the upper troposphere occurs so wind will flow from the warm area to the cooler area; this is thermal wind. Air above the cooler area sinks because it is more dense. This gives room for the thermal wind to also sink above the cooler area. The surface pressure in the cooler area is now higher than the warmer area since the sinking air is building up. A horizontal pressure gradient forms which causes wind on the surface to flow from the cooler area to the warmer area. I hope you understand since explaining this was a bit tricky without a lot of visualization. Also, check out wind flow maps of a monsoon. On the surface, wind flows from the colder area to the hotter area. But if you check the wind flow at higher altitudes, the wind actually reverses.
