Influenced by the Thermosphere thermal radiation that is highest along the mid distance between the 2 magnetic poles (aka magnetic equator) and lowest above the magnetic poles, the Temperature belts (Polar belt, Continental belt, ..etc) pick up the location of the magnetic pole for its center. As the magnetic pole in the Arctic region is moving from Canada towards Siberia, the North America is now moving into warmer belts and Europe is moving into colder ones. That also explained the mini Ice Age over Europe in the 17th century when the magnetic pole in the northern hemisphere wandered in the region bound by 20 to 30 degrees East and 77 to 84 degrees North.
As the two magnetic poles keep moving eastward (the distance between the 2 magnetic poles across the Americas increased by 5,360 km (3,350 miles) in 100 years, the magnetic intensity over the Atlantic is weakening causing the South Atlantic Anomaly in the mid distance between the 2 magnetic poles and increasing arrival of charged particles from the Sun. Collision of arriving Protons at high kinetic energy into the western and southern oceans causing ocean temperature to slightly increase. This causes Methane CH4 to get released from the encapsulating hydrates. CH4 is hungry for O2 whether at sea or in the air. CH4 plus 2 molecules of O2 produce CO2 and 2H2O. This explains increase CO2 and Water Vapor in the Air. As Vapor keep increasing, so will precipitation. Rain falls are on the rise so does snow when the temperature is right. The amount of Methane Hydrates stored in the ocean along the continental shelves at 0 to 500 meter depth is estimated at 1,000 the annual human energy consumption of all types on Earth.
Putting above pieces of information together, you could explain what has happened in Europe this summer of record cold events rain and snow falls.
