  Observed Dew Point Temperature: indicates the amount of moisture in the air
Dew points indicate the amount moisture in the air.
The higher the dew points, the higher the moisture content of the air at a given temperature.
Dew point temperature is defined as the temperature to which the air would have to cool (at constant pressure and constant water vapor content) in order to reach saturation.

  * Dew Point - (Meteorology): Definition   (Site not responding. Last check: 2007-10-26)
Dew point (dew-point temperature) The temperature to which a given parcel of air must be cooled at constant pressure and constant water-vapor content in order for saturation to occur.
Dew Point- the temperature to which a certain amount of air must be cooled in order for saturation to occur (a cloud or fog to form); the drier the air the lower the dew point and the more air is needed to be cooled for a cloud or fog to form.
Dew Point or Dew Point Temperature: The temperature to which a parcel of air must be cooled at constant water vapour content (and constant pressure) for saturation to occur.

 Dew Point
The dew point is the temperature the air must be cooled to for the air to become completely saturated, or for the air to have a relative humidity reading of 100 %.
The farther a part the air temperature is from the dew point the drier the air, and the lower the relative humidity.
Dew point is a direct measure of the amount of moisture present in the air, measured in degrees just like the actual air temperature.

The dew point temperature is the point at which the air must be cooled in order for the the air mass to become saturated (assuming there is no drastic change in pressure or moisture content).
The dew point is used a lot by TV meteorologists and seen on most current weather conditions because it's a great indicator of the moisture content of the air, or humidity.
Most people consider dew points near 55 degrees F and higher to be necessary for severe weather.
