Additional winds aloft forecasts are available on a high resolution interactive map from Graphical Forecasts for Aviation (GFA).

 

Graphics on this website utilize wind barbs to indicate wind direction on speed, which point towards the direction from which the wind is blowing. Guidance on interpreting these wind barbs is available here. 

 

Alaska, Hawaii, and CONUS wind/temp tables have been discontinued with the retirement of the NAM model. We recommend using the GFA wind and temperature forecast for higher resolution and more frequently updated data.
