CURRENT NAO - HIGHLIGHTS

Ensemble Mean AAO Outlook

Current NAO Highlights are for the Indice at a present strength of -0.5, to become increasingly Negative through Thursday. I would also like to point-out that even though the Arctic Oscillation (AO) Ensemble Indice Forecast from NOAA's Climate Prediction Center (CPC) does not appear to become Negative, the Antarctic Oscillation (AAO) neutralizes and trends very weakly Negative. Significant pattern changes that happen in the Northern Hemisphere, also occur in the Southern Hemisphere. Acting in the same manner as the AO, the AAO is directly-related with similar influences within the Southern Hemisphere. With that said, I strongly believe the AO & NAO will become neutral to weakly Negative during March 4-5. This will strongly encourage East coast cyclogenesis on March 6-7, with significant snow possible in western & northern New England.
