VALID 12Z TUE NOV 04 2014 - 12Z SAT NOV 08 2014


UNFORTUNATELY, THERE ARE NO RECENT RUNS OF EITHER THE OPERATIONAL
GFS OR ECMWF THAT CORRELATE WELL WITH ALL THE DISCRETE SYNOPTIC
SYSTEMS ACROSS THE ENTIRE ALASKA REGION. THE 00Z/31 GFS AND ECMWF
ARE CLOSE WITH THE HANDLING OF THE SPLITTING WAVE CROSSING THE
EASTERN ALEUTIANS 00Z/06 THURSDAY--THEN DIVERGE SHARPLY SHORTLY
THEREAFTER WITH THE DETAILS OF THE EDDIES SPINNING DOWNSTREAM OVER
THE GULF AND OFF THE PANHANDLE. THE 00Z/31 ECENS MEAN HONORS
CONTINUITY THE BEST, SO USED IT AS A SYNOPTIC GUIDE THIS
FORECAST--ADDING ISOBARS WHERE NEEDED TO BETTER RESOLVE INDIVIDUAL
SURFACE LOWS.
