Only in last series of articles we have informed about rare May snowing in the Netherlands, Germany, the UK (and Belgium and northern France) /https://mkweather.com/snowing-in-the-netherlands-on-7-may-extremely-rare-snowstorm/; https://mkweather.com/snowing-in-potsdam-berlin-germany-in-may-after-50-years/; https://mkweather.com/scotland-and-northern-england-under-the-snow-in-may-exceptionally-cold-spring-2021-continues//.
It´s possible, that mainly northwestern Europe and partly Scandinavia stay in colder weather pattern until early Summer 2021 /https://mkweather.com/245c-in-iceland-signalizes-extremely-cold-conditions-until-early-summer-2021-in-n-w-europe-year-without-spring//, but forecasts for Summer 2021 for Norway, Sweden and Finland are too temperature neutral or even cold.
Winter-like weather in these parts of Europe (similarly such as in British Islands and NW coasts of the continent) in late Spring 2021 is associated to to combination of factors such like La nina- volcanoes- solar cycle- melting Arctic- Global Warming Hole anomaly- weakening of Gulf Stream.
