THE EXTREME NORTHERN GULF JUST TO THE EAST-SOUTHEAST OF SEWARD. SNOW
SHOWERS ARE CONTINUING TO MOVE ONSHORE ACROSS THE COPPER RIVER DELTA
AND EASTERN KENAI AND MORE SNOW SHOWERS ARE OCCURRING ACROSS KODIAK
ISLAND AND THE NORTHERN GULF OF ALASKA AS THE COLD AIR ADVECTS ACROSS
THE WARMER WATERS OF THE GULF. COLD AND DRY AIR UNDER NORTHERLY FLOW
PERSISTS OVER THE SOUTHWEST INTERIOR WHILE LOW CLOUDS AND SNOW
SHOWERS ARE BEING OBSERVED ACROSS THE BERING SEA...ALASKA
PENINSULA...AND EASTERN ALEUTIANS. THE PRIMARY FEATURE OF NOTE ACROSS
THE CENTRAL AND WESTERN ALEUTIANS IS A VIGOROUS 969 MB LOW LOCATED
WELL SOUTH OF THE ISLANDS.

UPPER AIR...LITTLE CHANGE IN THE CURRENT PATTERN THROUGH THE WEEKEND
AND INTO TUESDAY. THE UPPER LOW THAT HAS BEEN ANCHORED OVER THE KENAI
WILL REMAIN IN THAT VICINITY...THUS ALLOWING THE COLD AND DRY
NORTHERLY FLOW TO CONTINUE ACROSS THE WESTERN HALF OF MAINLAND
ALASKA. MEANWHILE AN UPPER TROUGH EXTENDING WESTWARD FROM THE LOW
WILL REMAIN OVER THE BERING SEA WILL CONTINUE TO KEEP SNOW SHOWERS IN
THE FORECAST FOR THE PRIBILOFS...AKPEN...AND EASTERN ALEUTIANS
THROUGH MONDAY.

SURFACE...LOW PRESSURE ASSOCIATED WITH THE NEARLY STATIONARY UPPER
LOW WILL CONTINUE TO LINGER OVER THE NORTHERN GULF OF ALASKA
THROUGHOUT THE WEEKEND AND INTO NEXT WEEK. CONSEQUENTLY SNOW SHOWERS

WITH ISOLATED SHOWERS POSSIBLE ALONG THE EASTERN KENAI AND KODIAK
ISLAND. ELSEWHERE...NORTHERLY FLOW WILL CONTINUE TO KEEP CONDITIONS
COLD AND DRY ACROSS THE MATSU AND ANCHORAGE BOWL. IN THE WEST...THE
TRAIN OF LOW PRESSURE SYSTEMS WILL CONTINUE TO MARCH WELL SOUTH OF
