  title: Tomorrow.io Realtime vs Climate Normals Benchmark
  summary: Compare current conditions for a location against its long-term monthly climate normals.
  description: >-
    Anomaly detection in two calls. The workflow reads the realtime temperature
    for a point, then retrieves the monthly climate normals for the same point,
    and branches on whether current conditions are notably warmer than the
    typical seasonal baseline. This is the building block for "is today unusual?"
    dashboards and seasonal benchmarking. Every step spells out its request
    inline so the flow can be read and executed without opening the underlying
    OpenAPI description.
