Polar Vortex: Split could usher in late-March winter blast

A split in the Polar Vortex is becoming more likely toward the end of March. Currently, a stronger, consolidated vortex is keeping much of the cold air bottled up near the North Pole. While a late-month split appears likely, uncertainty remains regarding its exact placement, which would determine where the coldest air ultimately settles. At this point, areas across the Upper Midwest into the Northeast could see one final blast of winter-like air if the forecast holds. Fortunately, this will likely be the last time the Polar Vortex is a major factor this season.
