ENSO Forecasts http://iri.columbia.edu/our-expertise/climate/forecasts/enso/current/ “…the dynamical models are anticipating a moderately strong event to develop in the Northern Hemisphere’s late spring and summer. They are notoriously bad for seeing through the spring predictability barrier, though, so it should be noted that the statistical models are more conservative, predicting a neutral-to- weak El Niño event.” IRI March 2015 Climate Briefing, http://iri.columbia.edu/news/march-2015-el-nino/
Possible Pattern Influences http://www.cpc.ncep.noaa.gov/products/precip/CWlink/daily_ao_index/teleconnections.shtml +NAO very similar to +AO during boreal winter +PNA in winter: below- (above-) normal heights in C. Pacific (western N. America).

Some Scientific Questions Why does the spring predictability barrier for ENSO exist, and will the current El Niño intensify or not? Why has anomalous cold occurred over North America and nowhere else in the last two winters? Why did the mid-latitude pattern evolve as it did on sub-seasonal scales? Can we even identify why? What caused the MJO to achieve such a high amplitude this March, and what does it mean?
