A Sample Forecasting Procedure


Weather forecasters look at many types of data to help them build a forecast, and each forecaster will have their own approach. Here is a simple procedure to get you started.
  1. First look at current weather conditions:

    Surface Analysis

    Visible
    Satellite

    Infrared
    Satellite

    Radar

    A good stating point for formulating your forecast will be determining what is happening around the country today. Where are the major weather systems? Where has it been hot? Where has it been raining? Is any of this weather moving towards my forecasting site over the next forecasting period?
  2. Look at the National Weather Service hourly weather forecast graph and the forecast of fronts and precipitation:

    Graph

    Fronts/Precip
    Remember that the forecast day goes from about midnight to midnight local time. We forecast for a daily High and Low. The Low is typically recorded in the early morning hours of the day, while the high is generally reached in the afternoon. But check the hourly graph for the possibility that the Low and High might come at different times. For example, if a strong cold front comes through early in the day, the High might be in the early morning hours and the temperature might fall for the rest of the day, and the Low would be at the very end of the day.
  3. Look at National Weather Service precipitation forecasts:

    Precip
    The times for these plots are in UTC (or GMT); a contest day goes from 0600 UTC (about midnight in most of the U.S.) to 0600 UTC the next day. Click on the plots corresponding to those hours. Your precip forecast is for the whole day, so you would add the amounts from each 6- or 12-hr plot to calculate what the NWS is predicting for the entire contest day. Remember that you need to predict the amount in inches, and most locations receive amounts over one inch only a few times each year. On most days the precip forecast should be zero, and for many others it will be a few hundredths of an inch (e.g. 0.15 inches).
  4. Check and submit your forecast:
    Once you have determined your high, low, and precipitation amount, check it with the computer model forecasts shown in the table above. Are you close? Generally it’s a good idea to be fairly close to these computer forecasts, because they're typically quite good. Once you've entered your forecast in the form above, click the Submit button.
