That aspect of the climate is determined by where the highs set up over the Northern Atlantic and Northeast Pacific. Minor shifts to the east or west of high pressure in those locations slide the intervening trough (which occurs over North America) east or west. Last year, the March of the Nor'easters in March had the high over the Pacific situated more eastward with the Greenland high guiding the positioning of the eastern edge of the trough that the storms tracked. The shift west or east of those high pressure areas, when they set up, is a very minor shift. Since the polar vortex got strongly locked in place for the bulk of this Winter, there's not been many instances where a meridional jet stream pattern were presented. It just so happened that at the times they did, the resulting deep trough (the intervening one) found those high pressure areas in similar locations and the Midwest got hit. That vortex up there is supposed to be starting its seasonal breakdown. Its not. It's forecast to strengthen over the next couple weeks. The vortex breaks down when "Winter's over". The Northeast might still see some significant Winter after a pretty nice beginning to March. This vortex situation is unusual. Very, very, very cold air over the pole as the Sun angle starts bringing the usual warmth of the tropics northward into Spring. A very large differential is brewing. The reaction of a complex system as it moves to equilibrate such a large differential will be interesting this year, to say the least. Next Winter will be different but it will "rhyme" weatherwise. Just a nudge of those high pressure areas and the Northeast would see a more substantial Winter.
