The Cold Season is not giving up yet as a Dramatic Return of Major Arctic Blast heads for the Northeast U.S. this weekend

Hey, don’t pack the winter clothes yet, although we are already at the end of the first month of the meteorological spring season. Yet another and actually a pretty intense Arctic cold air intrusion will spread from Canada into the Northeast United States this weekend into early next week. Although the very active Polar Vortex during the recent cold season has finally broken down, its collapse will lead to some pretty dynamic weather patterns in the coming weeks.

While the Polar Vortex has significantly weakened with the arrival of the spring season recently, the cold weather is not giving up just yet. When the vortex is strong during the winter months, the frigid cold air is spread over the Arctic region, having occasional intrusions towards the southern latitudes. Once it weakens and its core warms, there are some of its final effects of cold air pools spreading down towards the ground.

One of these waves is emerging over North America this weekend, spreading into eastern Canada and Northeast U.S., thanks to favorable weather patterns developing over the continent. Bringing a strongly anomalous air mass over the region, with a refreshing few days of nearly 20 °F below normal temperatures.

“One interesting thing to note with the upcoming event is that exactly 10 years ago, in March 2012, one of the greatest heat waves was observed in many regions of the North American continent. Extremely warm air spread northward west of the Great Lakes region and subsequently spread eastward and into Canada. The warm surge brought a remarkably prolonged period of record-setting temperatures for many states.”
