It appears, that despite of strong NAO+, warm spell won´t hit northern parts of Europe (northern British islands, Scandinavia, Baltic region, nrothern European Russia) so strongly, such as was expected a few days ago, but mid-latitudes and Mediterranean should enjoy really warm / hot spring weather.

Summer +25°C is still possible closely to Paris, France and in southern and central parts of Germany, Switzerland, Austria and Czechia. Poland should be little colder, with +23/+24°C in southern half.
Warm spell should surprise in Slovakia, Hungary, Slovenia, Croatia, Bosnia and Herzegovina and Serbia, with temepratures up to +27°C and warmer than was expected should be in eastern Balkan, too, up to +24°C.
