MSLP forecasts for February-April from this month's update to the @CopernicusECMWF seasonal suite. Some suggestion of negative NAO lasting into March. Note that JMA, Météo-France, NCEP & UKMO have a weaker SSW signal because they are time-lagged ensembles. https://t.co/gYcx4PtzK5 pic.twitter.com/TUCea85bvJ
