The stars are all aligning to drive a significant shift in the overall regime towards one that should yield cooler (and, at times, colder) than normal temperatures as we navigate the back half of the month.
First, we have the MJO. Note how we’re set to slide into Phases 1 and 2 between now and end of the month.
These are progressively cold phases this time of year. Phase 1 has residual warmth across the Northeast (more seasonable here on the home front) before Phase 2 becomes overwhelmingly cold.
We then have the combo of the negative EPO and positive PNA. Both cold signals for our neck of the woods.
It’s no wonder model guidance is jumping on the persistent eastern trough to close out the month.
At some point in the 8-12 day period, I’d anticipate a true dislodge of true early season arctic air to get involved in the pattern. Think lows into the upper 10s, lower 20s and highs in the 30s. Still far too early to get specific with snow chances, but they will come before month’s end.
Stay tuned…
