Use it to forecast your flight trajectory! This is a great tool if you are planning a record attempt, long jump or longer than normal flight. This can be a confusing site, it is good to read the HELP links and make sure you select a trajectory forecast, NOT A dispersion forecast. Best idea is to play with site until you get used to it. Here you can see where the winds will take you at a variety of altitudes that you select as well as where you may end up.
Click here to get a text forecast from the NAM and GFS. This forecast will break down the atmosphere in 6 hour increments from the surface to the troposphere. The levels are broken down into standard aviation levels (1000mb, 850mb, 700mb, etc.) Both sights require the 3 letter station identifier (ie, cys, den, fcl).

This is a nifty link. Enter the three letter airport identifier and select the date and expected time of your flight and this model will give you a vertical wind forecast (scroll below the Skew-T chart) in very small (50 to 100 foot) intervals. Please note the grid point location the forecast is for, relative to your launch site (ie, gridpoint could be as much as 10 miles away from your launch site).

Great site to access the GFS and ETA models as well as the ECMWF models. GFS and ETA updated 4 times a day!
This is a 2 to 6 day outlook from a European model. It is good to compare this model to the MRF above to check for consistency. If the two models are not similar in their pattern this is a sign of uncertainty in the long range forecast, if so be wary of the long range forecasts!
