AREA FORECAST DISCUSSION
SOUTHCENTRAL AND SOUTHWEST ALASKA
500 AM ADT WED APR 27 2005

.DISCUSSION...

SOUTHCENTRAL...

ABOVE NORMAL TO RECORD HEAT CONTINUES FOR SOUTHCENTRAL ALASKA.

A LARGE PLANETARY RIDGE REMAINS OVER CENTRAL ALASKA.  500 MB HEIGHTS
AND THICKNESSES ARE VERY HIGH = WARM TEMPERATURES FOR THIS TIME OF
YEAR.  THOUGH MANY BASK IN THE EARLY SPRING WEATHER... THOSE IN LOW
LYING AREAS DOWNSTREAM OF (OR IN) LOCATIONS WITH LARGE WINTER SNOW
PACK SHOULD BE CAUTIOUS OF RISING CREEKS AND FAST WATER DURING THIS
PERIOD OF RAPID MELTING. PRIMARY AREAS OF CONCERN ARE ZONES 111 AND
145... BUT ONLY FOR NUISANCE FLOODING AT MOST.  UNDER THE RIDGE... A
LARGE FOG BANK PERSISTS OVER THE GULF AND NEAR KODIAK ISLAND. DENSE
FOG NEAR KODIAK CITY SHOULD BURN OFF WITH LATE MORNING MIXING.
COASTAL AREAS SHOULD HEAT ENOUGH TODAY GENERATE A SLIGHT SEA BREEZE
THIS AFTERNOON.  OTHERWISE A QUIET END TO THE WORK WEEK IS IN SIGHT.
A REX BLOCK LOOKS TO SET UP OVER MAINLAND ALASKA FOR THIS WEEKEND.
THE EASTERLY FLOW WILL POSSIBLY BRING SHOWERS TO KODIAK ISLAND.
EASTERLY WAVES COULD INITIATE ISOLATED CONVECTIVE SHOWERS FOR THE
REMAINDER OF SOUTHCENTRAL THIS WEEKEND... MAINLY OVER HIGHER TERRAIN.

SOUTHWEST...

A LARGE SYSTEM WITH A RAPIDLY WEAKENING LOW IS AFFECTING COASTAL
AREAS OF SOUTHWEST ALASKA... CERTAINLY INCLUDING THE ALEUTIANS AND
PRIBILOF ISLANDS.  THE MAIN CENTER IS JUST SOUTH OF SEGUAM ISLAND...
AND WILL RAPIDLY PROGRESS NORTH INTO THE GULF OF ANADYR LATE TONIGHT.
THE STRONG GULF RIDGE WILL IMPEDE WESTERLY PROGRESS OF THE FRONT...
WHICH LIES ALONG THE WEST COAST THIS MORNING. THE PRESSURE GRADIENT
IS STRONG ALONG COASTAL AREAS FROM THE OUTER CAPES OF BRISTOL BAY TO
NUNIVAK ISLAND AND WEST TO THE EASTERN ALEUTIANS.  ADVISORY LEVEL
WINDS AND GALES WILL PERSIST IN THESE AREAS THROUGH TODAY... AND
DIMINISH TONIGHT AS THE LOW PULLS NORTH. ANOTHER DEVELOPING LOW WELL
TO THE SOUTHWEST OF THE CHAIN WILL NUDGE THE WESTERN ISLANDS
BEGINNING TONIGHT. AS THE GULF RIDGE SLIDES WEST INTO THE EASTERN
BERING TOMORROW... AND CENTRAL BERING FRIDAY... THE WESTERN ALEUTIAN
LOW WILL STALL AND WEAKEN FRIDAY. BUT.. ANOTHER LARGER LOW ADVANCING
FROM EAST ASIA WILL LIKELY BRING GALES FOR THE WESTERN ALEUTIANS THIS
WEEKEND.
