to forecast
To make a prediction about a future development based on data, facts, or scientific methods.
Meteorologen prognostizieren für das Wochenende schwere Gewitter.
Meteorologists are forecasting severe thunderstorms for the weekend.
'Prognostizieren' (to forecast) is the verb related to the noun 'die Prognose' (the forecast). If you know that 'die Prognose' is a prediction, you can easily work out the meaning of the verb.
Die Prognose für die nächsten Tage ist gut.
The forecast for the next few days is good.
This verb belongs in a formal or technical context. It implies that the prediction is based on data and analysis, and is therefore used by experts, scientists, or in the news.
Wirtschaftsexperten prognostizieren ein baldiges Ende der Rezession.
Economic experts are forecasting an imminent end to the recession.
The prediction can follow the verb as a direct accusative object or be expressed by a subordinate clause with 'dass' (that). Both structures are very common.
Forscher prognostizieren einen Anstieg des Meeresspiegels.
Researchers are forecasting a rise in sea levels.
What is forecast is often something in the future. Typical objects are therefore 'eine Entwicklung' (a development), 'ein Trend' (a trend), 'Wachstum' (growth), 'das Wetter' (the weather), or 'die Wahlergebnisse' (the election results).
Niemand konnte diesen negativen Trend prognostizieren.
No one could forecast this negative trend.

Vorhersagen and prognostizieren both refer to a statement about a likely future development. „Prognostizieren“ places more emphasis on data, facts, or scientific methods and sounds more technical, whereas „vorhersagen“ is general and neutral. „Vorhersagen“ is usually appropriate in everyday situations, while „prognostizieren“ is often used in technical reports.
