Winter Storm Systems Lining Up for Northern Plains, Midwest

Brisk winds in the upper atmosphere will help propel low-pressure systems from the Pacific Ocean and “clipper” systems from Canada across the U.S. in they next two days, delivering considerable snowfall to parts of the northern Plains and Midwest while a high pressure is likely to bring rainfall to the Southeast. Strong wind will be a major feature of the systems expected to slide through the U.S. in the next few days, as a high-pressure ridge looks to cause a shift in the normal west-to-east movement of systems via the jet stream in the next week to 10 days, according to a new forecast Thursday. La Niña looks to remain strong through the next two weeks, though warming Pacific temperatures closer to the Central American coast show the system could begin weakening toward neutral as soon as early February.
