MMSM Airport and Weather

[Bluestar]

Upon arriving on a flight from KDFW to MMSM the Metar for MMSM was not on the Weather page.  MMSM is a valid reporting station.  Instead of MMSM the Weather page was showing MMMX as the nearest airport which is about 30 NM southwest of MMSM.   I created a flight from MMSM back to KDFW.  With the aircraft setting at MMSM I pushed the "Nearest Airport" button on the Weather page and it shows MMMX. If I check "Set zones by flight track..." the nearest airport shows up as MMCV which is more than a 235 NM north of MMSM and not located on the route I created. 
I am able to manually enter MMSM in the "Nearest airport" box and a current Metar is displayed but goes away if I press the "Nearest airport" button or check "Set zones by flight track".

I'm sure I've done something wrong, just not sure what.

To automatically determine the METAR stations near the flight track, PSX uses a METAR stations look-up table instead of the airport look-up table. This is because not all airports have a METAR station, and because some METAR stations are installed on a ship etc. The METAR stations from the look-up table can be viewed on the Instructor map when the "Met" checkbox is selected. Most of them are paired with an airport, but not all.

I built this METAR stations look-up table myself some years ago as this METAR stuff is not provided with the ARINC data from the nav database suppliers. So a few METAR stations at smaller airports may be missing here and there for the automatic determination along the flight track. But you can still enter the ICAO code of a database airport in that edit field as you correctly did. That's the solution in such a case. That manual entry will be used to find the related METAR in your last downloaded METAR files.

Thanks Hardy for getting back to me.  MMSM is a new airport and will eventually become the main airport for Mexico City.  All freight operators have been told they must relocate to MMMX by this summer.  DHL just built a $55 Million facility at MMSM.  There is also one runway that is dedicated to the military.  One thing for sure it is a lot easier to get into than MMMX.
