SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
400 PM AKST SUN FEB 27 2011
.ANALYSIS AND UPPER LEVELS...AN OMEGA BLOCK UPPER LEVEL PATTERN
PERSISTS WITH THE CENTER OF THE UPPER LEVEL HIGH OVER THE WESTERN
ALASKA COAST. THERE IS A POTENT NORTHERLY JET THAT EXTENDS FRONT HE
ARCTIC COAST THROUGH SOUTH CENTRAL ALASKA AND THEN SOUTH OF KODIAK
ISLAND. THIS JET IS A KEY FEATURE THAT IS ENHANCING THE STRONG NORTH
WINDS OVER SOUTH CENTRAL ALASKA AND THE GULF COAST. THE JET WILL
DRIFT EASTWARD AND WEAKEN OVER THE NEXT DAY.
WHILE THIS OMEGA BLOCK IS PREVENTING LOWS FROM ENTERING THE BERING
SEA THE PRESSURE GRADIENT BETWEEN THE LOWS SOUTHWEST OF THE REGION
AND THIS HIGH IS CAUSING WIDESPREAD GALE FORCE WINDS OVER THE
ALEUTIANS AND BERING SEA.
.MODEL DISCUSSION...
MODELS REMAIN IN VERY GOOD AGREEMENT ON THE SHORT-TERM SYNOPTIC
PATTERN...KEEPING THE EAST BERING RIDGE FIRMLY ANCHORED IN PLACE
THROUGH AT LEAST THE END OF THIS WEEK. HOWEVER THERE ARE NOTICEABLE
DISCREPANCIES IN THE WESTERN ALEUTIANS WITH REGARDS TO A LOW PRESSURE
SYSTEM THAT WRAPS NORTH AND WEST AROUND THE OMEGA HIGH AND MOVES
OVER THE WESTERN ALEUTIANS TONIGHT THROUGH AS LATE AS THURSDAY
AFTERNOON. THE ECMWF IS MORE PROGRESSIVE AND A TAD STRONGER
THAN THE GFS. WHILE THERE IS SOME DIFFERENCE IN SOLUTIONS THE IMPACTS
ON THE FORECAST ARE MINIMAL.
.SHORT TERM FORECAST...WINDY. A HIGH WIND WARNING FOR EASTERN PRINCE
WILLIAM SOUND AND THE COPPER RIVER BASIN CONTINUE. STRONG NORTH WINDS
WILL PERSIST THROUGH THE NIGHT FOR AREAS EAST OF THE ALASKA RANGE.
EXPECT AREAS OF BLOWING SNOW AND DUST OVER SOUTH CENTRAL. BY TOMORROW
THE WINDS WILL BEGIN TO BE RELEGATED TO MAINLY CHANNELED TERRAIN AND
BE NOTICEABLY WEAKER. SKIES WILL REMAIN MOSTLY CLEAR WITH NO FOG OVER
MAINLAND THE NEXT FEW DAYS.
SOUTHWEST ALASKA WILL SEE MOSTLY CLEAR SKIES BUT WILL NOT SEE THE
WINDS THAT SOUTH CENTRAL HAS HAD. THEY WILL REMAIN MOSTLY NORTH TO
NORTHEAST AND STAY UNDER 20 MPH.
THE ALEUTIANS AND BERING SEA WILL REMAIN BREEZY AND MILD AS SOUTHEAST
FLOW BRINGS WARM AIR INTO THE AREA.
.LONG TERM FORECAST...A STABLE WEATHER PATTERN REMAINS IN PLACE OVER
MUCH OF THE AREA UNTIL NEXT WEEKEND. THE UPPER LEVEL RIDGE SHOULD
RETROGRADE A LITTLE LATE IN THE WEEK WHICH COULD OPEN THE DOOR FOR
SOME SNOW SHOWERS ALONG THE GULF COAST. OVERALL THE WEATHER WILL BE
SLOW TO CHANGE THIS WEEK.
