weather map

any map or chart that shows the meteorological elements at a given time over an extended area. The earliest weather charts were made well before 1835 by collecting synchronous weather reports by mail. The first telegraphic collection of synoptic meteorological reports and their mapping for forecasting was accomplished by Urbain-J.-J. Le Verrier during the mid-1800s.
