Tableau Synoptique de Prévision Météorologique (1888)
On the occasion of World Meteorological Day, let us present to you a really exceptional object ! To the best of our knowledge, this 1888 Weather Forecast Synoptic Table could well be the first "instrument" designed for making weather forecasts !

With the two shortest branches of the moving arrow, the user was to indicate the
atmospheric pressure, direction of the prevailing winds and general weather tendency, which resulted with the main branch indicating the weather to come ! Of course !

Designed in Clermont-Ferrand by J.R. Plumandon, Meteorologist at the Observatoire du Puy-de-Dome, and A, Colomês, member of the Société Météorologique de France, this extremely rare object was the "result of the experience acquired during twelve years of making the daily weather forecast at the Observatoire du Puy-de-Dôme".

Congratulations to these pioneers, and fair winds to you !
