The mid-spring polar vortex is expected to bring wet and heavy precipitation across the eastern US, reaching into the midwest, northeastern states, and potentially as far south as North Carolina. March 15, 2021 - Dr. Judah Cohen from Atmospheric and Environmental Research (AER) embarked on an experimental process of regular research, review, and analysis of the Arctic Oscillation & Polar Vortex. After a mild winter, some of the United States can expect to see snow. Given the expanse and frequency of warm air through the first three weeks of the month, January 2020 is likely to finish much above average in temperatures over the eastern half to two-thirds of the nation, with the exception of the northern tier, where temperatures may be closer to, but still above, average.

The tropospheric polar vortex is lower, and at its edge is the polar jet stream — fast-flowing air that separates air masses. The polar vortex is a whirling cone of low pressure over the poles that is strongest in the winter months due to the increased temperature contrast between the polar … Technically they are known as the stratospheric polar vortex and the tropospheric polar vortex. The mild conditions may also be a problem for ice fishing interests. Prolonged mild weather during this time of year can threaten fruit trees and grape vines where the buds tend to soften.
