PG Surface Pressure Charts USA

For proper flight planning, information on meteo conditions are indispensable. The Surface Pressure Forecast Charts App will give you a 7-day outlook on the possible developments of the large scale meteo conditions in the USA, with separate charts for Alaska. The maps have the purpose to merely supply you with large scale, longer term info. To assess local conditions you will have to consult other, high resolution, sources.

To be able to download the charts in marginal internet connectivity conditions, the charts are supplied as low-resolution images, minimizing the file size.

Higher resolution images and zooming capability would suggest a reliability of the model outputs at a smaller scale. This has been discouraged by the meteorologists involved.

The app is light, fast and very easy to use. Use the buttons or swipe through the charts.
