The next round of frosts between 22.-27. April, hope for summer in early May

Earlier forecasts about possible +30°C in Central Europe are staying in the game, because main run of GFS expects colder weather such as many runs /, but warm weather should according to the newest forecasts hit Europe in traditional direction from southwest, including western Europe and before this warming, the last round of late frosts is prepared for the British Islands and continental Europe.

The next dose of cold Arctic air from Thursday to Tuesday, 22.-27. April will bring cold mornings 0/-5°C, rarely up to -8°C in parts of Europe. -10°C isn´t very rarely excluded, but not in densely populated areas.

Ensemble expect peak of very warm weather, with temperatures +25/+28°C in Central Europe already in the first May 2021 days, but main run (last outputs below) forecasts, that the warmest weather will come later, around 5. May (and only up to +26°C) 2021.
