Colder Weather Mid November On Course JOESTRADAMUS

Everything seems to be pointing to a Mid November weather pattern flip that will trend to a colder than average regime across the Eastern United States. The longer range weather indicators continue to point strongly in this direction.

Arctic Oscillation

There as been an almost unprecedented warming across the polar region over the past week that has set this all in motion. The Arctic Oscillation which is a measure of pressure changes across the Arctic regions. When the Arctic Oscillation is negative it is due to higher pressures across the polar regions. This tends to displace polar air southward into the middle latitudes. The index has been negative through much of October and is forecast to remain negative into the first half of November.

 

North Atlantic Oscillation

This is the same concept of the Arctic Oscillation on the North Atlantic side. This is more commonly referred to as the Greenland Block which creates the displacement of cold air from the North Atlantic into the Northeast United States. When the index is negative it weakens the winds across the North Atlantic. This allows cold air to build in Eastern Canada which spreads southward into the Eastern United States.

One of the missing ingredients in all this as been the state of the Pacific which has not been favorable for cold air to cross the polar regions and come into the United States. Today’s GFS at day 7 which is next Saturday November 5th. The state of the North Atlantic Oscillation being negative keeps it a little cooler in the Northeast  US than it otherwise would be.

COLDER WEATHER REMAINS ELUSIVE THIS WEEK

However beginning on Day 8 we see a large scale change in the overall pattern in the Pacific. The dominant fire hose jet stream across the entire Pacific begins to break down as a strong low pressure area and upper air storm form southeast of the Aleutians. This begins to change the flow in Canada to a more northwest flow which opens the door to some colder air to build and move into the Eastern US and elsewhere. This trend continues through day 16 on the GFS model

Watch what happens to the temperature anomalies from day 11 to day 16. Below normal temperatures take over a large chunk of the US East of the Rockies.

Now of course as always there is model disagreement on how this all plays out with the European having a bit more of a dynamic approach by day 10. However the more important takeaways here are the strength of higher pressures building across the polar regions (negative A.O. & N.A.O.) and a building ridge in the west which also displaces cold air southward.

colder weather

The bottom line is that the process of a colder weather pattern setting up for mid November onward is underway even though the specifics of how we get there in the day to day weather at this point remain a mystery. It seems that winter may want to get to an early start across the east and possible before Thanksgiving.
