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.
As the Northern Hemisphere moves from summer into autumn, the North Atlantic atmosphere begins a seasonal reorganisation. Faster cooling at high latitudes strengthens the temperature contrast between polar and subtropical air, influencing the jet stream and creating a more favourable environment for mid-latitude weather systems.

During the night and in the morning there is a chance of thunderstorms and local showers. For this afternoon no more showers are expected but it remains partly cloudy. A heavy precipitation event in the order of >0. 8" is predicted for Monday. The sun will not be visible. The chance of precipitation is moderate or near 50%. Temperature highs are likely to reach 75 °F. Overnight into Monday a strong breeze is blowing (25 to 32 mph). In the course of day blows a fresh breeze (18 to 25 mph). Gusts to 50 mph are possible. Winds blowing overnight from South, in the morning from West and during the afternoon from Northwest. The weather forecast for Castelo Branco for Monday can be accurate in parts but deviations are expected. Check again for latest updates.

The animation shows the wind conditions of the storm at 200m above ground, which corresponds well with expected gusts at the surface. Choose other time steps to see the forecast of the storm.
The location marker is placed on Castelo Branco. 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.
