The Met High data also is a preconfigured set of wind, pressure and precipitation content but now it is at a resolution (0.25 degrees) 12x greater than the Fast data. For example, in any 3 degree x 3 degree block. Met High will provide 144 data points as opposed to 12 data points for the Fast product. But an important factor if using low bandwidth the satellite, file size increases proportionally. A 20 second download of the Fast content turns into a 3 minute download of the High product.
We also use NOAA's new GFS FV3 model as the base of this level. Met High data is available at 1 to 7 day forecast lengths. Each day is further broken into 4 frames separated by 6 hours apiece with the models updating at approximately 5, 11, 17, and 2300 UTC.
