Dew trend

Dew-point spread is broadly stable.

Moonlight impact

There is no qualifying primary imaging window tonight, so moonlight impact should be checked hour by hour.

Long-term model performance & local calibration

The system archives each original forecast and checks it when reliable observations arrive. It currently records and suggests only; it cannot change the V2 score or tonight’s verdict.

Independent models expose fetch time only. The current upstream responses do not provide a common initialization time, so it remains N/A and fetch time is not mislabelled as model run time.

Data boundaries & known limitationsMissing fields remain missing; nothing is guessedRead notes
  • Astrospheric v2 exposes Cloud, Transparency, Seeing, Temperature, DewPoint, WindDirection and Wind; it does not expose individual Pro Cloud Ensemble members.
  • RDPS, HRDPS, GFS, ICON and NBM comparison is independently sourced through Open-Meteo and may differ from the Astrospheric app's Pro ensemble processing.
  • CAMS aerosol data is a coarse smoke/haze proxy, not local satellite cloud-motion analysis.
  • ECCC City Page Weather is an official but experimental city forecast for Winnipeg; it is a short-range cross-check, not a Glenlea cloud-percentage model.
  • The final decision remains forecast guidance; verify the sky and road/site access before travel.

Update log

What changed in each published version

v0.2.3
  1. v0.2.3 · Responsive layout consistency

    • Stopped English and French metric names from breaking inside words; compact phone labels now keep every hourly row the same height.
    • Extended priority gradients and row dividers to the true section edge, removing the blank clipped strip on iPhone layouts.
    • Added a dedicated tablet layout, restored the sky timeline on larger screens and enlarged interactive controls to comfortable touch targets.
    • Localized remaining mixed-language labels and retested the briefing, drawers and hourly dialog across portrait phones, tablets and desktops.
  2. v0.2.2 · Portrait forecast readability

    • Restored the phone briefing to a left-hand verdict and right-hand score ring, with proportions tuned for narrow portrait screens.
    • Compressed the pinned metric column and hourly columns so more consecutive hours can be compared at once.
    • Added full-height midnight separators, date labels, a current-time marker and a compact touch guide.
    • Checked English, French and Chinese at multiple portrait phone sizes while retaining the past 24 hours and full future model coverage.
  3. v0.2.1 · Mobile layout & diagnostics

    • Reflowed the score ring on iPhone-sized screens so long English and French conclusions keep the full text width.
    • Completed dynamic English/French interface copy and added wider device/layout checks.
    • Added a privacy-safe diagnostic download and version-aware rendered-page cache.
  4. v0.2.0 · Public Beta briefing

    • Introduced the Night Mission Briefing, hourly conditions strip and future-night comparison.
    • Added forecast verification in shadow mode without changing production scoring.
