Wind Chill
Wind Chill takes into the account how the speed of the wind effects our perception of the air temperature.
Heat Index
The Heat Index uses temperature and the relative humidity to determine how hot the air actually "feels."
Humidity
Humidity itself simply refers to the amount of water vapor in the air.
Dew Point
Dew point is the temperature to which air must be cooled for saturation (100% relative humidity) to occur, providing there is no change in water vapor content. The dew point is an important measurement used to predict the formation of dew, frost, and fog.
Barometric Pressure
The weight of the air that makes up our atmosphere exerts a pressure on the surface of the earth. This pressure is known as atmospheric pressure.
UV Index
UV Index assigns a number between 0 and 16 to the current UV intensity.

Difference between a watch and a warning?
A Watch means that conditions are favorable for severe weather to occur. A Warning means that severe weather is occurring in or imminent for your area.
What is the difference between isolated and scattered?
Scattered is a more common occurrence than isolated. In other words, you are more likely to see rain when there is a chance of "scattered showers" than when there is a chance of "isolated showers".
What is the difference between partly cloudy and partly sunny?
Partly Cloudy skies means "Part Clouds" - Most Sun. Partly Sunny skies means "Part Sun" - Most Clouds. In other words. Partly Cloudy is 'more sunny' than Partly Sunny.
