FEW CHANGES WERE MADE TO THE MEDIUM RANGE FORECAST FOR ALASKA. THE
29/00Z ECENS AND GEFS MEANS FEATURE A SLOW-MOVING---AND
EAST-SOUTHEASTWARD MIGRATING UPPER-LEVEL CIRCULATION. ITS
POSITION...ANCHORING A LONG WAVE TROUGH ALONG 160W AND A
DOWNSTREAM RIDGE ALONG 120W-130W. THIS PATTERN LEADS TO A SERIES
OF NORTHEASTWARD-MOVING SHORTWAVES---FAVORING A SUBTROPICAL
CONNECTION AND SOUTHERLY TO SOUTHWESTERLY FETCH---RESULTING IN
PERIODS OF CLOUDINESS AND PRECIPITATION ALONG THE NORTHWEST COAST
OF THE NORTH AMERICAN CONTINENT. THIS INCLUDES THE ALASKA
PANHANDLE...SOUTH/SOUTH WEST COASTS.
