Cloud cover is broadly stable through the night.
Dew-point spread is broadly stable.
There is no qualifying primary imaging window tonight, so moonlight impact should be checked hour by hour.
Models show some disagreement; check again just before departure.

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 · 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.
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.
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.
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.
