NWS Grid Point (Forecast Office and Grid Cell for a U.S. Coordinate)

nws/grid-point

Resolves a United States latitude and longitude to its National Weather Service forecast office and forecast grid cell (office id, gridX, gridY), plus the point's time zone, county, forecast zone, nearest radar station and nearest town. Feed the office id and grid cell into NWS Grid Forecast to get the forecast. US only: coordinates outside the United States and its territories return a clear error. National Weather Service data as served by Omnial, not an official NWS product.
