Could you build this?
Partial Building a weather dashboard app in SwiftUI or Flutter is routine, but collecting, archiving, geo-indexing, and evaluating multi-gigabyte forecasts from ECMWF, GFS, and ICON against real-world radar/station observations requires substantial backend data engineering.
What it would actually take: The backend requires automated ingestion pipelines running on AWS/GCP to ingest NetCDF/GRIB2 binary data feeds from NOAA (GFS), ECMWF, and DWD, alongside real-time METAR and citizen weather station APIs. The hard parts are spatial-temporal interpolation at global scale, high-throughput caching of historical vs predicted data points, and real-time accuracy scoring per GPS coordinate. This demands meteorological data engineering expertise and scalable geospatial database architecture (PostGIS/DuckDB/TimescaleDB).
Discussion
5 comments analyzed.
Competitors mentioned: Open-meteo models (IFS, AIFS, AIGFS)
Concerns raised: Forecast API error 429 - too many concurrent requests, Only uses model data, not actual observations, Rain scoring too binary/inconsistent with low rainfall, Measures model confidence not real forecast accuracy
Feature requests: Minimum rain threshold for scoring, Adjustable lookback window in scoring tab
