AREA FORECAST DISCUSSION
SOUTHCENTRAL AND SOUTHWEST ALASKA
500 PM ADT SAT MAR 17 2007

.DISCUSSION...GFS WITH SOME SHORT TERM MODIFICATION WITH NAM WILL BE
USED IN AFTERNOON GRID PRODUCTION. WILL COOL DOWN EASTERN TEMPS SOME
IN THE SHORT RANGE FROM PREVIOUS PACKAGE.

.UPPER AIR...STUBBORN LOW CENTER OVER THE GULF MAY MOVE OVER THE
EASTERN AK INTERIOR TUE AS LOW AMPLITUDE RIDGE MOVES INTO THE WESTERN
GULF. MODELS STILL SHOWING EASTERN RUSSIA HIGH RETREATING WEST SOME
AS COLD AIR PUSHES SOUTH FROM THE POLE TO OVER THE CENTRAL BERING SEA
ON TUE. PRIMARY LOW CENTERS SETS OVER THE POLE AND ASSOCIATED TROUGH
DIGS SOUTH TO OVER THE WESTERN MAINLAND/EASTERN BERING SEA TUE NIGHT.
THE MAIN TROUGH DIGS SOUTH OF 155W FROM POLEWARD CENTER TO GULF WITH
MINOR CENTERS OVER THE EASTERN ALEUTIANS WED NIGHT IF THIS PATTERN
ACTUALLY DEVELOPS WILL LIKELY SEE STORM TRACK SHIFT TO NORTHERN GULF
BY MID-WEEK.

.EAST...SHORT TERM SOLUTIONS FOR THE NORTHERN GULF ARE FAIRLY CLOSE
WITH KEEPING SOME WEAK COMPLEX IN THE REGION THROUGH SUN. TRICK WILL
BE HOW MUCH PRECIPITATION MAKES IT INLAND AS UPPER CENTER FORMS OVER
THE WESTERN GULF AND WEAK INVERTED TROUGH IN THE LOWER LEVELS FORMS.
FOR NOW WILL BRING A CHANCE OF SNOW/SNOW SHOWERS SUN. SOME INCREASE
IN CLOUD COVER WILL TEND TO OFFSET OVERNIGHT COOLING THROUGH SUN/MON.
LOWERED TEMPS SOME FROM LAST RUN AS WE WERE LESS AGGRESSIVE ON EXTENT
OF CLOUD COVER OVER THE EASTERN MAINLAND. IF LONG RANGE PATTERN HOLDS
TRUE...COULD SEE A WET/WINDY/WARMER PATTERN SETTING UP BY MID-WEEK.

.WEST...WESTERN MAINLAND LIKELY TO REMAIN ON THE COLD AND DRY SIDE
FOR THE NEXT COUPLE OF DAYS. MOST OF THE ACTION IN THE SHORT TERM
WILL BE OVER THE ALEUTIANS. 990S CENTER WELL SOUTH OF SHEMYA MOVES
WEST AND WEAKENS THROUGH TONIGHT. DEVELOPING STORM CENTER OVER THE
NORTH PACIFIC BRING STORMS TO THE CENTRAL AND WESTERN ALEUTIANS SUN.
WINDS MAY GET UP NEAR WARNING LEVELS IN THESE AREAS...SO FOR NOW WILL
GO WITH HIGH WIND WATCH FOR SUN AND MONITOR SYSTEM EVOLUTION. STORM
CENTER WILL INTENSIFY TO UPPER 960S/LOWER 970S SW OF SHEMYA SUN
EVENING THEN MOVE WEST AND WEAKEN MON. SECONDARY STORM CENTER COMES
INTO PICTURE SOUTH OF THE EASTERN ALEUTIANS TUE. MODELS DIFFER A BIT
ON THIS ONE...BUT FOR NOW WILL GENERALLY LEAN TOWARD THE GFS.
