WEATHER PATTERN DEVELOPING AS PROMISED THE LAST COUPLE OF DAYS. HIGH
PRESSURE FORMING AND EXPANDING NORTHWARD OUT IN THE EASTERN BERING

THE AXIS NEAR AND SLONG 165W. THIS HIGH WILL EFFECTIVLY BLOCK ANY

STILL LIKELY FROM 175W TO 180 UNTIL MONDAY AFTERNOON.

WIDESPREAD AREA OF LIGHT SNOW FROM KODIAK ISLAND (PAKH) NORTHWEST TO
BRITOL BAY AND ACROSS THE YUKON KUSKOKWIM DELTA ASSOCIATED WITH UPPER
TROF. TROF WILL SOUTHEAST AND SNOW WILL END FROM THE NORTHWEST SUNDAY
NIGHT.

EASTERLY FLOW ON NORTH SIDE OF GULF SYSTEM SPREADING CLOUDS RAIN AND
SNOW, WHICH EXTEND FROM THE NORTH GULF COAST TO THE TANANA VALLEY,
WESTWARD. WEAK ECHOES HAVE SHOWN UP IN THE SUSITNA VALLEY WITH SNOW
AT CANTWELL AND SHEEP MOUNTAIN. COOK INLET AREA FROM WILLOW TO KODIAK
SITTING IN THE CLEAR ZONE MOST OF SUNDAY. SUNDAYS EASTERLY FLOW
BECOMES NORTHEAST SUNDAY EVENING, AS THE GULF LOW PULLS EASTWARD.
