AREA FORECAST DISCUSSION
SOUTHCENTRAL AND SOUTHWEST ALASKA
500 AM AST SAT JAN 20 2007

.DISCUSSION...

AT UPPER LEVELS THIS PART OF THE HEMISPHERE IS DOMINATED BY A MASSIVE
TROUGH EXTENDING FROM ASIA TO WESTERN AK. EMBEDDED WITHIN THIS TROUGH
IS A RIDGE OVER THE WESTERN BERING. A LARGER SCALE RIDGE IS CENTERED
OVER THE ALASKA PANHANDLE. AT THE SURFACE...A SIGNIFICANT LOW WELL
SOUTH OF KODIAK ISLAND IS APPROACHING THE GULF...AND A DECAYING LOW
IS NEAR NUNIVAK ISLAND.

UKMET AND GFS ARE IN GOOD AGREEMENT...ONCE AGAIN BRINGING THE LOW
FROM SOUTH OF KODIAK TO PRINCE WILLIAM SOUND ON SUN. THE NAM IS THE
OUTLIER...BRINGING THE LOW TOWARD YAKUTAT. THE FORECASTS TEND TOWARD
THE GFS UKMET SOLUTION.

IN THE ALEUTIANS AND BERING...THE LOW NEAR NUNIVAK WILL DRIFT IN THE
EASTERN BERING AND BRISTOL BAY...FINALLY CROSSING THE AKPEN SUN
EVENING. THIS WILL KEEP COLD ADVECTION ACROSS THE CENTRAL AND EASTERN
ALEUTIANS WITH SNOW SHOWERS THROUGH SUN. THE RIDGE OVER THE CENTRAL
BERING MIGRATES SLOWLY EAST AND CUTS OFF PRECIP EARLY NEXT WEEK.

OVER SOUTHWEST AK...THE AXIS OF THE UPPER TROUGH WILL SLOWLY MOVE
OVER THE REGION INTO THE BEGINNING OF NEXT WEEK WITH CONTINUED SHOWER
ACTIVITY. THIS WILL FINALLY END TUE.

SOUTH AND EAST OF THE AK RANGE...RESIDUAL SNOW SHOWER WILL FALL OVER
THE NORTH GULF COAST AND ADJACENT INLAND AREAS TODAY. AS THE LOW
MOVES INTO THE GULF...FLOW WILL BECOME MORE SOUTHEAST AND MOST SHOWER
ACTIVITY WILL END BY THIS EVENING OVER INLAND ZONES. NORTHEAST FLOW
AHEAD OF THE LOW WILL SPREAD BLIZZARD CONDITIONS OVER KODIAK ISLAND
BEGINNING AT MIDDAY AND PERSISTING UNTIL MIDNIGHT. MEANWHILE...RAIN
AND SNOW AND WIND WILL REACH THE NORTH GULF COAST BY EVENING AND THEN
SNOW MOVES INLAND OVERNIGHT. SOUTH CENTRAL AND THE MAT-SU WILL
RECEIVE SNOW SUN AS THE UPPER TROUGH PASSES OVERHEAD. FOLLOWING
PASSAGE OF THE TROUGH...SOUTHWEST FLOW SETS UP FOR ANOTHER ROUND OF
SNOW SHOWERS FOR THE KENAI AND SOUTH CENTRAL MON. ANOTHER LOW TAKES
AIM AT THE NORTH GULF COAST TUE NIGHT...BUT AT THIS POINT THE
TRAJECTORY TAKES IT EAST OF PRINCE WILLIAM SOUND SO ONLY THE COAST
AND POSSIBLY THE COPPER RIVER BASIN WILL BE AFFECTED WED.
