Enter a US airport name to see the full range of equally probable 8 day temperature and precipitation forecasts predicted by the GEFS forecast model.

This tool allows users to search for over 60,000 US substations by owner name (as included in the OpenStreetMap database). The tool also identifies substations that have been newly added to the OpenStreetMap within the last month.
