No. MJO 8 and 1 are warm phases in New England in April.
The warm anoms in Maine and Southeast Canada will continue to shift south on guidance as it catches on. The cold anoms over the central US SE and Mid Atlantic.
That will bust with the MJO to phase 8 to 1, with 1 being the warmest for this time of year in New England.
You’ll probably see the cold anoms in the mid Atlantic, Long Island to del Marva.
