How Well Can You Predict Tomorrow's Weather?
ES2013  Surface Analysis Maps

There’s no single "right" way to predict the weather—weather forecasting is as much an art as it is a science. Meteorologists rely on the wealth of available data, their knowledge of atmospheric processes, and their experience and insight to make predictions.

A good way to begin gathering data for your own prediction is to examine maps of current weather conditions, called surface analysis maps. These maps use numbers and symbols to display weather data. For example, the blue contour lines on the map represent areas of equal atmospheric pressure, measured in millibars (mB). You can examine a key to the other weather station symbols at: Surface Weather Station Symbol Key .
