Which Weather Forecast to Trust?

Below are two very different forecasts.  The temperatures are not that far off from each other, but compare the chance of precipitation!  Note that the TWC forecast starts at 4pm and Weatherbug at 5pm.  These forecasts were pulled offline within minutes of one another.  I just do not understand how such a discrepancy in precipitation forecasts is possible when both places have access to the same historical data.  Do they have models that are that vastly different?  If you know anything about this, please leave a comment explaining.

I'm no weather expert, but sometimes I visit the NWS radar page to see if I can interpret the radar as being closer to one end of the forecast spectrum or the other.
