Winter '20 / '21 - Severe Weather Europe: Winter Forecast
"The La Nina phase will reach quite a formidable strength at its peak but is expected to start to weaken towards spring 2021."
"Historically, the most typical effect of a La Nina is a strong blocking high-pressure system in the North Pacific."
"North America winter forecast looks fairly solid to be a classical La Nina type winter. Most of western Canada is to expect colder and snowier conditions, along with Alaska.
"The United States expects to see a “dipole” pattern or a “two-faced” winter. The Northern [sic] United States are expected to be normal to colder and wetter. This increases the chance of more snowfall, but more likely towards the western half, and less likely in the eastern parts.
"The Southern [sic] United States can slowly prepare for warmer and mostly
drier than normal winter weather. This however does not imply that [sic] no
cold front can reach the southern states. It just implies that [sic] in a La
Nina pattern, it is much less likely to get frequent cold fronts down to
the very south."
