Specific atmospheric conditions around us which can change minute-by-minute, day-to-day.

Weather forecast

A prediction of specific future weather conditions, such as daily maximum temperature at a location, up to several days ahead, with the estimate frequently becoming more uncertain with increasing lead-time. Weather forecasts are often based on computer simulations of the atmosphere known as NWP, Numerical Weather Prediction.

Weather observation

Also known as a weather report, is a snapshot of the weather conditions at a certain location and at a certain time. An observation may be as basic as an air temperature reading but can include wind speed and direction, visibility, humidity, precipitation, cloud cover or soil surface temperature. A long-term average of a location's weather observations e.g. 30 years, determines the location's climate.
