GFS and GDPS weather models only contain predictions at 3 hour intervals and no prediction exists at 20:00 UTC. As a result, there is no 20:00 hour when training a linear regression model and using it to make a prediction.

As a work around I am taking the prediction at 18:00 and getting a bias adjusted value, do the same at 21:00 and finally use linear interpolation to estimate the bias adjusted value at 20:00.
