The gfs had a premature triggering of its Mjo forcing hence its Operationals overdoing things, now it's settled down.....Id go for the ECM evolution very feasible right up to day 10......Nice cold snap with possible snow showers, brief change as operationals get their act together before retrogression and a lovely Neaster as the CONUS call it...ECM right in a slower MJO forcing......Feb is becoming very interesting...
