7-day Forecasts

Two weekly forecasts are generated every Sunday at 1800z.

The idea is that you can sort your plans for that week – perhaps you’ll reconsider the trip to Cardiff and go to Glenforsa instead, or perhaps instructors will shuffle their IMCR and PPL(A) students around.

Both these forecasts work the same way; they generate a table where the cell colour is worst case and the likely case is highlighted text.

Trends or mitigating conditions are highlighted, along with probable cloud base and visibility.

The difference is the forecast areas.

7 Day Regional Forecast:

7 Day North West UK Training Areas Forecast:

Tom takes into account the following:

  • VFR, IFR, MVFR or LIFR rules.
  • Icing risk, with the logic including freezing levels, cloud cover, precipitation.
  • Density altitude.
  • Wind at surface and probable cruise altitudes.
  • Atmospheric stability.
  • Specific mountain weather logic to identify unstable air masses, orographic lift, inversions, or valley fog.
  • NOTAMs filtered appropriately

Caveats:

  • Still debugging it and teaching the AI some lessons so bear with me
  • Some IR lessons go further in search of a friendly airport which will give you an IR approach
  • Airspace is not shown because this tool informs your flight planning you do using regulated sources
  • Forecasts are always wrong, so obviously don’t use this weekly forecast as your only pre-flight planning tool
