NATIONAL WEATHER SERVICE ANCHORAGE AK
100 PM AKST TUE JAN 25 2011

.MODEL DISCUSSION...NAM AND GFS IN CONSIDERABLE DISAGREEMENT ON
EASTERN GULF LOW THAT FORMS TONIGHT.  EAST DESK IS GOING TO USE GFS
SOLUTION WHICH PRODUCES A PRONOUNCED CUT-OFF LOW WHICH MOVES ONSHORE
OVER ICY BAY WED LATE MORNING. MODELS ALSO HINTING AT LOW FORMING
JUST SOUTH OF KENAI PEN WED AND THEN MOVING NORTHWARD DURING THE
AFTERNOON.

THE POWERFUL ALEUTIAN STORM THAT THE MODELS HAVE BEEN FORECASTING IS
ON TRACK TO IMPACT THE CENTRAL AND EASTERN ALEUTIANS BEGINNING
MID-DAY TOMORROW.  GFS AND NAM IN GOOD AGREEMENT ON PRESSURE AND
POSITION THROUGH THUR AFTERNOON.  THIS SYSTEM SHOULD BOTTOM OUT
AROUND 955 WITH PLENTY OF STRONG SE WINDS FOR AREAS EAST OF 170W.
ALSO LOOKS AS PRETTY GOOD SOURCE OF COLD AIR ON WESTERN SIDE OF STORM
SO EXPECT SOME STRONG NW WINDS THU MORNING ACROSS CENTRAL BERING AND
CENTRAL ALEUTIANS.

.ANALYSIS AND UPPER LEVELS...AT THE SURFACE THERE IS AN ELONGATED LOW
IN THE NORTHERN BERING THAT MOVES TO THE WEST WED AND THEN MERGES
WITH CENTRAL ALEUTIAN STORM. THE FRONT ASSOCIATED WITH THIS SYSTEM IS
CURRENTLY MOVING THROUGH SOUTHWEST AK. CURRENT NW GULF LOW WILL
CONTINUE TO PRODUCE RAIN ALONG THE COAST AND SNOW SHOWERS INLAND.

.SHORT TERM FORECAST...
BERING REGION...EXPECT STRONG SE WINDS AND RAIN EAST OF 170W STARTING
WED MID-DAY.  WEST DESK MIGHT ISSUE HIGH WIND WARNING FOR SOUTHERN AK
PEN.  AS NOTED ABOVE POTENTIAL FOR SOME STRONG NW IN CENTRAL
ALEUTIANS LATE WED NIGHT THROUGH FRI MORNING. EXPECT SNOW AND BLOWING
SNOW AS WELL.

SOUTHWEST...AS FRONT MOVES NORTHWARD THIS AFTERNOON PRECIP WILL
DECREASE BUT LOW CLOUDS TO FOLLOW. FRONT FROM ALEUTIAN SYSTEM SHOULD
MOVE ONSHORE BEGINNING LATE THU MORNING. LOOKS LIKE SOME POTENT
NORTHEAST TO SOUTHEAST WINDS CAN BE EXPECTED THUR AND FRI. LOOKS AS
IF PRECIP COULD BE MAINLY SNOW...WHICH MEANS POTENTIAL FOR BLIZZARD
CONDITIONS AS WELL.

SOUTHCENTRAL...UNSETTLED WEATHER WITH RAIN ALONG THE COAST AND CHANCE
OF SNOW INLAND THROUGH WED NIGHT.  LOOKS LIKE REMNANT OF FRONT
ASSOCIATED WITH ALEUTIAN STORM WILL MOVE THROUGH COOK INLET BEGINNING
LATE THU NIGHT. LITTLE CONFIDENCE ON DETAILS HOWEVER AS LITTLE
SUPPORT ABOVE THE SURFACE FOR MORE THAN LIGHT PRECIP.

.LONG TERM FORECAST...UPPER LEVEL RIDGE IS STILL FORECASTED TO
DEVELOP OVER THE GULF AND ALASKA ON THU.  THIS WILL STEER ALEUTIANS
SYSTEM TOWARD THE GULF OF ANADYR FRI NIGHT. LOOKS AS IF ANOTHER
PACIFIC STORM MOVES TOWARD EASTERN ALEUTIANS SUN AFTERNOON.  HIGH
PRESSURE FORMS OVER THE GULF SO LITTLE IN THE WAY OF STORMS OVER THE
WEEKEND.
