NCEP NAM Jet Stream Forecast Model

Jet Stream at ~41,000 feet

Graphs below show the forecasted 300hPa pressure height(in meters) and the associated winds(in knots). This is roughly equivalent to the jet stream winds at 12.5 kilometers or 41,000 feet. The actual height varies due to atmospheric pressure changes.

Check NOGAPS Jet Stream Model for a 350 hPa Model with jet stream winds at 9 kilometers or 31,000 feet.
