Weather can function as a noun and a verb, but as a noun, it refers to the “outside conditions of the atmosphere.” Is it rainy, cold, hot, humid, or dry? Those are adjectives that describe the weather. Whether is a conjunction that is typically used to indicate “doubt or a choice between two possibilities.”

These are temperature, atmospheric pressure, cloud formation, wind, humidity and rain. A small change to any of these conditions can create a different weather pattern. Every weather pattern has a knock-on effect, creating a ripple effect around the world. That's why weather can sometimes seem chaotic.

Weather is defined as the state of the atmosphere at a given time and place, with respect to variables such as temperature, moisture, wind speed and direction, and barometric pressure.
