ALASKA EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
1239 PM EST SUN NOV 16 2014

VALID 12Z THU NOV 20 2014 - 12Z MON NOV 24 2014


THE GLOBAL NUMERICAL MODELS HAVE SHOWN BETTER CLUSTERING IN THE
LAST COUPLE MAJOR DATA CYCLES ACROSS THE NORTHEASTERN PACIFIC AT
THE MEDIUM RANGE--ENOUGH SO THAT AN EVEN BLEND OF THE STEADIER
ECMWF AND ECENS MEAN SHOULD SERVE THE REGION WELL THROUGH 192
HOURS. THE BOMB DEPICTED BY THE 00Z/16 ECMWF STANDS OUT AGAINST
THE BACKGROUND OF ALL THE OTHER GUIDANCE, SO SWITCHED TO PURE
ECENS MEAN BY THE END OF THE PERIOD. ALL IN ALL, IT LOOKS LIKE AN
ACTIVE PERIOD FOR THE ALEUTIANS AND PACIFIC COAST, WITH SOME
SEEPAGE OF ARCTIC AIR INTO THE EASTERN INTERIOR.
