Hi Emily, The observations certainly support La Niña waning to ENSO-neutral conditions, so why does the CFS suggest weak La Niña conditions continuing through summer (http://www.cpc.ncep.noaa.gov/products/people/wwang/cfsv2fcst/images3/nino34MonadjPDFC.gif)? This seems to be at odds with virtually everything else (https://iri.columbia.edu/our-expertise/climate/forecasts/enso/current/?enso_tab=enso-sst_table). Thanks, -- Matt Bunkers, SOO, NWS Rapid City, SD
