Weather forecasting has moved from a nightly broadcast to the centre of operational decision-making. The meteoblue Weather & Climate Summit in Basel this October will examine how forecasting reached that position and where the field is heading.
When you open a weather app, the forecast appears simple: a temperature, a weather symbol and perhaps a probability of rain. It is easy to assume these values come directly from one weather model. In reality, model output often goes through comparison, local adjustment, observation-based updates and quality control first.

Overnight into Saturday it will be cloudy and rainy. In the course of day some clouds break up but local showers are still possible. The sun will not be visible. A very high chance of Precipitation near 90% is forecast. Temperatures as high as 44 °F are foreseen. On Saturday expect a moderate breeze (12 to 18 mph). Gusts to 24 mph are possible. Winds blowing at night and in the morning from Southwest and during the afternoon from West. The weather forecast for Shaliuhe for Saturday is likely to be accurate.
Pressure: 1023 hPa
Timezone: CST (UTC +08:00h)
By comparing today's temperatures to 40 years of historical data we can see whether today's forecast is unusually warm (red areas) or cold (blue areas). Coloured dots show observed actual temperatures from professional and private weather stations.
The location marker is placed on Shaliuhe. This animation shows the precipitation radar for the selected time range, as well as a 2h forecast. Orange crosses indicate lightning. Data provided by nowcast.de (available in USA, Europe, Australia). Drizzle or light snow fall might be invisible for the radar. Precipitation intensity is colour coded, ranging from turquoise to red.

The real-time satellite image combines visible light during daytime with infrared radiation during nighttime. At night, the image is not dark as infrared radiation can detect temperature differences. Unfortunately, low clouds and fog are difficult to distinguish from ground temperatures and thus can be almost invisible during the night. Meteosat satellite images for Europe are updated in real-time every 5 minutes. GOES-16/GOES-17 (North & South America) and Himawari (Asia) images update every 10 minutes.
Precipitation is estimated from radar and satellites. Precipitation estimates from satellites are less accurate at night than during daytime.
