Pressure

A drop in atmospheric pressure is often associated with cloudy or rainy weather. Conversely, high pressure is usually associated with fair weather. Variations in pressure lead to the development of winds, which in turn influence our daily weather.

Dew Point

The dew point temperature is the temperature to which the air must be cooled to reach saturation (assuming air pressure remains the same). The dew point is a direct measure of the amount of moisture present in the air, and directly affects how you feel... or in other words... measures the amount of humidity in the air. Remember, the temperature never drops below its dew point, but can drop to it. Generally, we start to feel some discomfort when the dew point gets to or just above 60 degrees

Chance of Precipitation

Precipitation is any kind of water that falls from the sky as part of the weather. This includes snow, rain, sleet, freezing rain, hail, and virga.
