.DISCUSSION...

SKIES ARE GENERALLY CLEAR ACROSS SOUTH CENTRAL ALASKA AS THE REGION
COMES UNDER A DRIER MORE NORTHERLY FLOW. A WEAK RIDGE DOMINATES
WEATHER FROM THE CENTRAL ALEUTIANS AND BERING SEA EAST TO THE
WRANGELL MOUNTAINS.

HOWEVER A DEEP LOW PRESSURE WILL BE DROPPING OUT OF THE CHUKCHI SEA
OVER THE WEEKEND LEADING TO A CHANGE IN THE WEATHER PATTERN.
TEMPERATURES ARE EXPECTED TO COOL ESPECIALLY WEST OF THE ALASKA
RANGE. THE AIRMASS IS RELATIVELY DRY AT THIS TIME AND ANY SIGNIFICANT
SNOWFALL SHOULD BE CONFINED TO TH4E MOUNTAINS.

ANOTHER DEEP LOW CURRENTLY SOUTH OF SHEMYA IS EXPECTED TO MOVE SLOWLY
EASTWARD..BUT TO THE SOUTH OF THE ALEUTIAN ISLANDS OVER THE WEEKEND.
THE WARM FRONT ASSOCIATED WITH THE LOW SHOULD MOVE AS FAR EAST AS
UNALASKA BY LATE AFTERNOON SATURDAY. WINDY CONDITIONS WITH RAIN AND
FOG WILL DOMINATE THE WEATHER TO THE WEST.

THE CURRENT MODELS ARE REMARKABLY CONSISTENT WITH THE EVOLUTION OF
THE TWO WESTERN LOWS. MESOETA HAS NOW PHASED UP WITH THE GFS WITH LOW
IN SOUTHERN GULF OF ALASKA.
