The models side by side

What it tries: Four model runs for Lisbon (two of IPMA's, MET Norway, Open-Meteo) drawn as what they are, dashed and named hypotheses about the future, against what was actually measured (solid), for mean wind, gusts and rain.

What it shows badly: A point forecast for one grid cell is compared with one station, which is unfair to both; only one model here gives gusts, and gusts are what the warning is about. None of these lines is our forecast.

An experiment from the Labs, one of several ways of showing the same data so they can be compared. It reads only this site's published JSON: weather/forecast.json, weather/stations.json, weather/lisbon-rain.json, weather/airport.json, weather/warnings.json. Click any mark for its row or edge, its source and the time it was read. Not a warning service: for the warning itself, IPMA and ANEPC.
