The Meteorological Service of Canada makes this GRIB2 format database available to private sector meteorologists, academics, and the general public. It contains data from analysis systems along with output from many of the Canadian Meteorological Centre’s Numerical Weather Prediction (NWP) models. The data is free, under standard terms and conditions.
The Environment Canada Global Deterministic Prediction System is a global model and may be a good way of verifying the GFS models output.
Generally, when two or more weather models are in agreement, you can feel more assured that their forecasts are reliable. When weather models disagree, there may be instability in the weather system and the results may be less reliable.
For more information on the model, see the official site.
