The privately owned, for-profit weather-forecasting company AccuWeather has a team of over 100 meteorologists who work together to predict the weather. Weather forecasts have been around since the beginning of civilization (link resides outsideibm) where humans used recurring meteorological and astronomical events to better monitor weather patterns and plan for seasonal changes. Past, current, or predicted temperature values displayed in a weather report may not always represent the warmest or coldest temperature for a location on a particular day. Temperature Precipitation. Additionally, there are options such as RainViewer (for rain forecasts taken from dedicated. Because they orbit at the same rate that the Earth rotates, allowing them to focus on one spot for most of their time in orbit, the satellites provide near-continuous images over a wide area. This skill may be a good mathematical measure of the forecast accuracy but it is no longer a direct measure of the accuracy and, thus, could confuse the forecast users whose sole concern is how the forecasts for my location have been compared to the observations in the past, i.e., the plain accuracy of the forecasts. Weather can only be forcasted with decent accuracy for about 3 days. Weather forecasting is a technology used to predict the weather.
