When you see the MJO repeatedly amplify in the Indian Ocean and amplification is blocked over the Pacific, that will continue. That means the next time it cycles and amplifies again, likely in the back half of April, it will likely amplify again in the Indian Ocean. That MJO phase is favorable for ridging being off the East Coast and us being in low-latitude SW flow aloft here... favorable for severe in the spring and favorable for southern wintry weather early in the year. In order for stuff to shift north/west of Dixie, you want the MJO to amplify closer to the Pacific so that ridging is stronger and closer to the Southeast coastline or onshore, or you just want the seasonal migration that happens after April. In late May 2011, the MJO cycled again and amplified in the IO, but the seasonal migration northwestward had already begun, and the pattern still aimed at the Plains instead.
