RELIED MOSTLY ON THE ECENS MEAN AS A SYNOPTIC GUIDE THIS FORECAST
PACKAGE. THE TIMING DIFFERENCES IN THE PACIFIC NORTHWEST DAY 5
BETWEEN THE ECENS AND NAEFS--MOSTLY DRIVEN BY SLOWER MSC
MEMBERS--ARE DIMINISHING. BY DAY 7, THE ECENS AND NAEFS MEANS ARE
QUITE COMPARABLE WITH THE SOUTHERN STREAM CYCLONE OVER THE UPPER
MIDWEST. THE PRONOUNCED SPLIT IN THE FLOW AT THE MEDIUM RANGE HAS
BEEN MOST CONSISTENTLY HANDLED BY THE ECENS MEAN, WITH THE 00Z/25
OPERATIONAL ECMWF GOING AGAINST THE GRAIN WITH ITS DEEP CYCLONE
NORTH OF THE GREAT LAKES DAY 7.
