Can the dew point temperature be more than drybulb temperature? I am extracting data from WRF model output for a specific area. The area I am extracting data for is 5000m above mean sea level. When plotting on a graph, I found that the dew point temperature is higher than the dry bulb temperature.  

Is it possible that the dew point can go higher than the dry bulb? If yes, what is the inference of this phenomenon? Or can I simply assume that WRF could not calculate temperature values properly for this hill station?
Dew point gives an indication of the moisture content of air; it is the temperature at which air can no longer hold water vapour.

The following graph shows the relations of dew point to air temperature (dry bulb) for various levels of humidity.



For humidity less than 100 percent, the air temperature is always higher than the dew point temperature and for a humidity of 100 percent air temperature equals the dew point temperature.

The dew point cannot be higher than the dry bulb temperature, it can only be lower of equal to it.
