A meteogram is a time cross-section display of output from a computer model over a fixed geographical point. Meteograms are useful tools for predicting weather at a specific location. Meteograms on the website are available from the MLAPS, LAPS, GFS and GASP models.
The Surface meteograms show dew point temperature, temperature, precipitation, wind speed, wind direction and pressure at the surface.
The Atmosphere meteograms show temperature, wind direction, wind strength, relative humidity and height at the 850hPa level. Atmosphere meteograms also show the 1000-500 thickness.
A snow meteogram is also available on the website from the GFS model. It displays snow level, 850hPa relative humidity and 700hPa relative humidity.
