Credit to @philklotzbach for the wind shear graphics. Interestingly, the MDR shear flipped to below normal in Sep and low-level wind anomalies shifted to W in the subtropics as an anom. low pressure dominated the nw Atl ~40-50N. The dry air aloft from 50-70W nearly disappeared pic.twitter.com/2CN83RqA5v
