VALID 12Z THU JAN 29 2015 - 12Z MON FEB 02 2015


CONTINUE TO RELY PRIMARILY ON THE NAEFS MEAN AS A SYNOPTIC GUIDE
FOR THE ALASKA REGION AT THE MEDIUM RANGE. THE EUROPEAN CENTRE
GUIDANCE--NORMALLY A RELIABLE YARDSTICK FOR SORTING THE FLOW AT
LONGER TIME RANGES--HAS BEEN PLAGUED BY IRREGULARITIES OVER THE
PAST SEVERAL DAYS OF RUNS. THE STRONG SIGNAL FOR A SUPPRESSION OF
CYCLONIC ACTIVITY AND MOISTURE APPEARS TO BE A GOOD ONE, WITH COLD
AIR ANCHORED OVER THE DEEP INTERIOR NEAR THE YUKON.
