The GEFS is suggesting MJO remaining stuck in phase 6 days 11-15, which is consistent with the 850 mb wind composite for that MJO phase. When the anomalous -VP can progress more into the C/E. Pacific, the WWB should follow. However, models keep delaying this E-ward progression. pic.twitter.com/CuX6oN55Xh
