, 2011, becoming the deadliest 24-hour outbreak in U.S history. According NOAA and the SPC, there were approximately 190 tornadoes reported with 320 deaths within the southern, mid-western and northeastern U.S. In the current study, Arctic sea ice loss affecting the North Atlantic Oscillation, a negative ENSO episode, Gulf of Mexico Sea Surface Temperatures (SST's) and an unusual shift of dry-line associated with parent mid-latitude cyclone (MCL) are potentially influenced by global change in association with the outbreak and studied using NCEP/NCAR reanalysis, GFS modeling, NCEP/CPC CAMS & NOAA/ESRL/PSD NOAA/AOML/TCHP analysis, and stability parameters obtained from remote sensing. Larger implications state the Arctic sea ice lost reversed upper-level wind distribution and affected major wind systems such as the jet stream. Reduced albedo in the arctic increased solar insolation and shifted the temperature differential between latitudes, potentially perturbing Earth's feedback system.
