Current NAO Highlights are for the Indice to weaken from a present strength of around +0.5, the NAO will become neutral by the end of the week. However, I would like to look at the Eastern Pacific Oscillation (EPO) which is moderately Positive. The EPO at a current strength of around +2.0, will weaken as significant changes take place over the eastern Pacific from this point on. The map below from NOAA's Earth System Research Laboratory (Physical Sciences Division) demonstrates the affects of a Positive EPO on North America.
