Happy Sunday. :)
The major weather cycles driving the pattern right now are a moderate La Nina (colder than normal equatorial Pacific Ocean, cold Pacific Decadal Oscillation (PDO) cycle with colder than normal North Pacific Ocean temperatures, a very warm Atlantic Multidecadal Oscillation (AMO) cycle and a strong relatively symmetrical Polar Vortex.
All have teamed up to keep Eastern North America cold here in January. CLICK ON IMAGES FOR A LARGER VIEW.
