There will be a few chances for Arkansas to pick up some of this cold air. We generally get about 4-7 inches of snow in an average winter. Maloney E. and D. Hartmann, 2000: Modulation of hurricane activity in the Gulf of Mexico by the Madden-Julian Oscillation. The question How severe was this winter? does not have a simple answer. Ski resorts on the other side of the country may end up relying on artificial snow rather than natural snow this winter with below-normal snowfall in the forecast for the spine of the Appalachians from northern Georgia through Pennsylvania.
