We just had a really nice clean phase 8 look IMHO. Here's some bullet points supporting that thought from the CPC MJO update yesterday. Western hemisphere is phase 8. I think this potential will respond in kind given a little lag time. Which lands squarely on this period. There's research that supports phase 8 being the most favorable for Northeast US snow events. Beyond all of this, there is potential of a strat PV split. It's on some of the guidance. Probably at least partially due to the MJO transit through the Pacific. We just had a precursor pattern for that as well, which brought Sunday's event. So will just need to monitor developments.
• Following a long-lasting, incoherent MJO, the RMM based index increased in amplitude, emerging from
the unit circle in phase 6 (Western Pacific) and
becoming highly amplified.
• Once eastward propagation began, the signal quickly
moved into the Western Hemisphere.
• The signal had been showing propagation in the
upper-level VP anomalies before it was seen in the
RMM index and may be “catching up”.
