- 25. Final Drought 2012-2013 Thoughts 2012-13 Fall and Winter none-too-kind for most thus far! U.S. (contiguous) has seen a 14% decrease in areal drought coverage since its peak (65%) last September, but we still have 51% of the U.S. in drought heading into Spring as compared to 30% last year this time Most improvement seen in the Southeast and eastern Corn Belt Great Lakes very low Snow pack in the Rockies is a big concern (MO Basin) So, recent storms have helped, but….. Spring rains will be critical for soil moisture recharge (grain/forage prospects tied to this) No buffer/carryover coming into 2013, unlike 2012…will be living rain event to event much earlier…heat waves likely again if below-normal soil moisture recharge takes place
