Descripción:
The dew-point is the temperature air would have to be cooled to in order for saturation to occur. The dew-point temperature assumes there is no change in air pressure or moisture content of the air. Dew-point does not change with temperature of the air; very much different from relative humidity.

The dew-point can be used to forecast low temperatures. The low will rarely fall far below the observed dew-point value in the evening (unless a front brings in a different air mass). Once the temperature drops to the dew-point, latent heat must be released to the atmosphere for the condensation process to take effect. This addition of heat offsets some or all of further cooling.
Introduction to seasonal forecasting:
The production of seasonal forecasts, also known as seasonal climate forecasts, has undergone a huge transformation in the last few decades: from a purely academic and research exercise in the early '90s to the current situation where several meteorological forecast services, throughout the world, conduct routine operational seasonal forecasting activities. Such activities are devoted to providing estimates of statistics of weather on monthly and seasonal time scales, which places them somewhere between conventional weather forecasts and climate predictions.
 
In that sense, even though seasonal forecasts share some methods and tools with weather forecasting, they are part of a different paradigm which requires treating them in a different way. Instead of trying to answer to the question "how is the weather going to look like on a particular location in an specific day?", seasonal forecasts will tell us how likely it is that the coming season will be wetter, drier, warmer or colder than 'usual' for that time of year. This kind of long term predictions are feasible due to the behaviour of some of the Earth system components which evolve more slowly than the atmosphere (e.g. the ocean, the cryosphere) and in a predictable fashion, so their influence on the atmosphere can add a noticeable signal.
