This is what he said on Twitter, replying back to BAMWX. "The MJO is headed into Phase 8, and the PNA and NAO look mighty favorable. A slight warm up at the end of the month is likely to be followed by another cold polar or Arctic air mass. Brief warm-ups happen in a cold pattern just like brief cool downs do in warm ones." I totally agree with this 100 percent.
Ya'll forgetting that the MJO is also a forecast and has fluctuated on predictions recently I believe.
