Just downwind, however, these patterns often see troughs dipping south across the eastern half of Canada, allowing for intrusions of frigid air and an active storm track to develop across the region.

The strength of an El Niño also has an effect on these wintertime patterns. Stronger El Niños tend to push the ridge farther to the east, sometimes allowing above-seasonal conditions to push all the way to the Great Lakes, shunting the cold and stormy conditions toward Atlantic Canada.
Folks heading south of the border aren’t immune from El Niño’s effects on winter weather, either.
Popular vacation destinations in the southern United States, especially in Florida, tend to see foul weather during winters influenced by El Niño, including wetter-than-average conditions and more frequent opportunities for severe thunderstorm outbreaks.
It’s important to note that these are general patterns. Patterns that bring above-seasonal temperatures don’t preclude colder conditions, nor would a cooler-than-average pattern prevent occasional warmups.
