RV Weather

• Short-term forecast, emphasizing weather parameters most important to visitors in the Jenny Lake / String Lake / Leigh Lake region
• Animations of expected weather radar updated daily.
  • Other weather parameters (snow, wind, etc.) added when they may be significant.
  • For orientation, animation maps show Wyoming and a small portion of the surrounding states.
• Temperature graphic is for the Airport. Subtract a couple of degrees for String Lake and 3-5 degrees if a visitor asks about Colter Bay.
• The wind gusts forecasts are usually (in the summer) a reasonable forecast for average sustained wind speeds at 9,000 – 11,000 feet for backcountry hikers.
• For those with access to Grand Teton Park Radios: Channel 16 is NOAA Weather Radio
