The next two months of winter will bring milder weather for southern B.C. with more active storm tracks, followed by bouts of cold, says The Weather Network (TWN) in their winter update.
TWN’s website calls for, “spells of milder weather for southern B.C. along with a more active storm track at times, followed by bouts of cold. The risk of heavy coastal snows in southern BC will become increasingly less likely as February progresses.
“La Niña conditions are likely to persist across the equatorial Pacific Ocean. Independently, a major shift in the weather patterns across the Northern Hemisphere is currently underway, which will modify the kind of weather impacts La Niña has delivered during the first part of winter,” said meteorologists working for TWN.
Environment Canada’s website said La Niña contributes to “the changes in the tropical Pacific that are accompanied by large modulations of the jet stream within the middle latitudes, shifting the point at which the stream normally crosses North America. The shifted jet stream contributes to large departures from the normal location and strength of storm paths. The overall changes in the atmosphere result in temperature and precipitation anomalies over North America which can persist for several months.”
The Farmer’s Almanac predicted “temperatures on the East and West coasts will be more in line with average to normal winter conditions,” on their website.
