Frosts and ground frosts in Europe next 7 days, protect your flowers and harvest!

Arctic air comes after wind pressure system over NW Europe

While windstorm Ellen and Francis in August 2020 brought wind gusts 143 km/h (89 mph) and 163 km/h (100 mph) above lands of Europe, current wind pressure low system is weaker, with winds up to 128 km/h in mountains (Cairngorm, UK, 1245 MASL) and 104 km/h in low areas (Krakenes, Norway, 4 MASL).

In addition, Met Office says, that "Strongest storm is determined by lowest pressure and maximum recorded non-mountainous wind gust is also included for reference.", therefore, it is still missing 6 km/h to reach status of windstorm in lower situated areas.

Despite of various terminology (it is not clear, if somewhere in Norway was reached more than 110 km/h last 48 hours and if for UK classification of windstorm territory of Norway is valid, too), wind pressure low associated with remnants of hurricane Laura will bring a week of cold mornings across large parts of Europe.

September: in Le Puy (832 MASL) in France was measured only +3,4°C, in Stockholm +3,4°C, in Burgos, Spain (894 MASL) +3,5°C, in Vitoria, Spain (532 MASL) +3,8°C, in Horsens, Denmark +3,9°C, in Oberstdorf, Germany (810 MASL) +4,0°C, in Karlove Vary, Czech republic (503 MASL) +4,3°C and on Thursday +2,7°C, in Elseborn in Belgium (564 MASL) +4,5°C, in Hannover, Germany +5,0°C, Liesek, Slovakia (614 MASL) +5,0°C.
