Keeping An Eye On the Arctic

Within the past couple of days, I've noticed a significant buildup of cold air near the Arctic circle. At one point, I saw a reading of -20 degrees F this morning.

Just a short time ago last week, the temperatures were already falling; however, at least temperatures were near 10 degrees. Therefore, a drop of nearly 30 degrees within the past few days is quite significant.

As daylight continues to fade near the Arctic circle, not much rebound in temperatures is expected. Look for signs of the cold air building south over time. Any number of strong low pressure systems could tap into the 'cold reserve' and sling it southward toward the U.S. border.
