Meteogram 7-Day

[Miloslav Tlamicha]

The Meteogram 7-Day is a multi-purpose forecast tool providing hourly weather data for the next 7 days. It is available with a point+ subscription.

Display Overview
• Shows four stacked diagrams with different weather variables.
• Light yellow background = daylight.
• White background = nighttime.
• Valid for the selected location, anywhere on Earth.
• Updated whenever accessed, with nowcasting data included.
• Local time is used; dashed vertical line = current time.
• Most recent model update time = bottom left corner.

Weather Variables

1. Temperature
   • Hourly temperature curve for the next 7 days.
   • Area under the curve shaded with layered colour bars for readability.
   • Daily min/max values shown as numbers.
   • Weather pictograms displayed above the curve.
2. Precipitation
   • Vertical blue bars = precipitation amount (mm or inches).
   o Dark blue = total precipitation.
   o Light blue = showers.
   • Symbols indicate type:
   o Rain = no symbol
   o Snow = *
   o Frozen mix = x
   o Freezing rain = ▼
   • Purple curve = precipitation probability (from 20-member model ensemble).
   • Blue curve = relative humidity (%).
   • Probability is based on model consensus for a 50×50 km grid cell.
3. Clouds
   • Cloud cover shown by grey shading at various altitudes (km).
   • Brown bar = average altitude of surrounding terrain.
   • 0% = clear sky, 50% = half covered, 100% = overcast.
   • Low-level shading at ground level can indicate fog.
   • Example patterns:
   o Cold front: gradual build-up of low clouds.
   o Thunderstorm: clear morning → rapid afternoon build-up → evening clearing.
4. Wind
   • Light blue curve = mean wind speed (10 m above ground).
   • Dark green curve = wind gusts.
   • Arrows (3-hour intervals) = wind direction:
   o Arrow up = South wind
   o Arrow right = West wind, etc.
