Lingering Polar Vortex Impacts Will Translate to Chilly Start to May in Midwest and Northeast

Although the polar vortex is gone, it does not mean that it is not still exerting some level of influence on the weather in the U.S. The lingering impacts from the past winter vortex will keep the threat of frost in place across some portions of the Midwest and the Northeast in the days ahead, spelling potential trouble for agricultural interests and home gardeners. Read on for what you can expect in this part of the country for temperatures.

How the Polar Vortex is Still Influencing Temperatures in Parts of the U.S.

The leftover effects of a shift in the polar vortex early in the spring are still driving many of the weather patterns across the central and eastern U.S. as May kicks off. It is going to be a chilly start to the month for millions of Americans thanks to this influence. Some residents may be reaching for jackets and that heat dial for the first half of the month.

The residual effects of where the polar vortex was anchored in March and April have resulted in an atmospheric traffic jam at the jet stream level. While the displacement of the polar vortex is not over, the jet stream is still positioned in a way that will support persistent waves of cool air coming down from Canada and into the Midwest and the Northeast.
