GUIDANCE IN GOOD AGREEMENT THROUGH 84 HOURS. GENERALLY PREFER THE
NAM FOR ITS BETTER HANDLING OF LOCAL EFFECTS.

THERE IS AN UPPER LEVEL RIDGE OVER SOUTH CENTRAL ALASKA THAT
STRETCHES NORTHWARD ACROSS THE INTERIOR INTO THE ARCTIC OCEAN. THERE
IS ANOTHER RIDGE BUILDING OVER THE BERING SEA. A SMALL LOW IS ALONG
THE SOUTHWEST COAST OF ALASKA AND MOVING TO THE SOUTHEAST. AN ARCTIC
LOW CENTERED JUST TO THE SOUTH OF BANKS ISLAND CANADA IS MOVING
TOWARDS THE SOUTHWEST AND WILL HAVE AN INCREASING IMPACT ON WEATHER
OVER SOUTHERN ALASKA OVER THE NEXT FEW DAYS.

THE SOUTHWEST ALASKA LOW WILL SLIDE SOUTHEAST TONIGHT AND INTO THE
GULF OF ALASKA ON MONDAY THEN INTO THE ALASKAN PANHANDLE ON TUESDAY.
AT THE SAME TIME THE CENTRAL ALASKA RIDGE WILL WEAKEN AND MOVE
NORTHWEST. AS THE CANADIAN LOW MOVES SOUTH AND THE BERING RIDGE
BUILDS THE UPPER LEVEL FLOW OVER SOUTHERN ALASKA WILL BECOME MORE
NORTHERLY THROUGH TUESDAY AND NORTHWESTERLY BY WEDNESDAY. THIS WILL
INCREASE THE GAP WINDS AND KEEP THE AIR MASS COLD AND DRY.

MONDAY AS THE CENTRAL ALASKAN RIDGE WEAKENS. LATE MONDAY NIGHT AND

ALOFT BECOMING NORTHWESTERLY.

FOR SOUTHWEST ALASKA/BERING SEA/ALEUTIAN ISLANDS...CHANCES OF
PRECIPITATION WILL CONTINUE TONIGHT OVER SOUTHWEST ALASKA AS THE LOW
OVER THE AREA MOVES SOUTHEAST. THESE SHOWERS SHOULD PRETTY MUCH END
