ALASKA EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
1142 AM EST MON JAN 26 2015

VALID 12Z FRI JAN 30 2015 - 12Z TUE FEB 03 2015


AFTER NEARLY A WEEK OF ERRATIC SOLUTIONS, THE ECMWF AND ITS
ATTENDANT ENSEMBLE MEAN HAVE FINALLY LOCKED ONTO THE STEADY SIGNAL
THAT THE NAEFS RESOLVED EARLY. THE EUROPEAN CENTRE GUIDANCE IS
QUITE ACCURATE ONCE IT SETTLES ONTO SOMETHING, SO USED IT
LIBERALLY THIS FORECAST PACKAGE. THE REAL DIFFERENCE BETWEEN THE
MORE REFINED GRAPHICS AND MASS FIELDS TODAY AND THE MORE DILUTE
ONES ISSUED THE PAST SEVERAL DAYS IS MORE OFFSHORE GRADIENT OVER
THE GULF. OTHERWISE, THE PATTERN IS DOMINATED BY SUPPRESSIVE
BLOCKING AT THE MEDIUM RANGE.
