Weather Watch -- From Weather Stations
Professional weather stations collect weather data using many sensors. These stations collect the current temperature, maximum and minimum temperatures for the day, humidity, atmospheric pressure, wind speed and direction, cloud cover and other data. Many weather stations also provide radar images. These are useful to determine the intensity of precipitation for about 100 miles around the radar. Many sources combine radar data from several local radars to produce regional radar images.
This portion of Weather Watch provides links to data and relative tutorials for each data source. Several online resources allow you to select a professional weather station to see current weather data. Their data can be compared with your own weather data. While many of these resources allow the selection of a weather station by zip code, look carefully at the exact location of the weather station. Some zip codes cover very large areas. The nearest weather station may be some distance away, in a significantly different location (on the other side of a body of water or hill), or in a different population area. Other online resources show basic weather data for a much larger region. This broader scope is needed to follow the development of large weather systems and to track snowstorms across the country.
