Weather Tracker lets you follow trends in the weather by recording daily high and low temperatures and measured precipitation over a calendar year.

You can display plots of temperature and precipitation over any selected week, month, or quarter, or for the entire year. You can determine temperature extremes and average values. By loading other weather files, you can compare a previous year's weather with current weather trends. Or, you can compare files created using another city's weather. Monthly summary plots and tables are also provided. Several printing options are available and any number of weather files can be saved for later use.
