Seasonality Core from Gaucho Software is a weather station for the Mac. It can display the latest forecasts, as well as current and past conditions. You can also customize the display to fit your needs.
Seasonality Core can monitor multiple locations; I counted slots for 17 locations in the standard display, which is more than most people will ever need. Seasonality Core comes with a database of over 30,000 cities, towns, and interesting spots by the side of the road, so your location is probably covered. Once you specify a location to track, you can monitor the current temperature, wind speed and direction, pressure, cloud cover, dew point, humidity, visibility, rainfall, snowfall, and quite a bit more. You can also graph any conditions you're monitoring over time. A radar/satellite map includes weather front information, cloud cover, and precipitation intensity.
If you would like to have your own personal weather station without spending hundreds or thousands of dollars, Seasonality Core may be just what you're looking for.
Seasonality Core is $24.99. A demo is available.
