SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
200 PM AKDT FRI AUG 17 2012

.MODEL DISCUSSION...
MODELS INITIALIZED WELL ON SYNOPTIC FEATURES. FORECAST TRENDS ARE IN
GOOD AGREEMENT AND REASONABLE THROUGH THE SHORT TERM (WEEKEND).
AFTERNOON FORECAST PACKAGES WILL BE BASED IN PART ON THE NAM MODEL.

UPPER LEVELS...
THE UPPER LOW CENTER OVER THE CENTRAL GULF OF ALASKA LIFTS NE INTO
WESTERN CANADA SAT. A WEAK SHORT WAVE RIDGE MOVES OVER SOUTHCENTRAL
ALASKA TONIGHT AND THE EVENTUALLY TRACKS TO THE EASTERN GULF AND
WESTERN CANADA SAT NIGHT. A LONG WAVE TROUGH... COMPRISED OF A LOW
CENTER OVER THE ARCTIC OCEAN AND A CENTER OVER THE BERING
SEA...SHARPENS AS THE BERING SEA CENTER INTENSIFIES AND MOVES TO THE
EASTERN BERING SAT MORNING. THE BERING SEA CENTER THEN MOVES NORTH TO
OVER NORTON SOUND SUN. THE NET RESULT WILL BE BROAD AND MOIST SWLY
FLOW IMPACTING THE MAINLAND THIS WEEKEND.

SURFACE...
A STACKED LOW OVER THE CENTRAL GULF THIS AFTERNOON WILL MOVE NE UNDER
UPPER CENTER TO OVER WESTERN CANADA SAT. HIGH PRESSURE WILL BUILD
ACROSS THE GULF AND SOUTHCENTRAL TONIGHT...THEN SHIFT EAST SUN
AFTERNOON. THE DEVELOPING LOW OVER THE BERING SEA MOVES TO NEAR
NORTON SOUND SUN. THE ASSOCIATED OCCLUDED FRONT IMPACTS SW ALASKA
TONIGHT AND SOUTHCENTRAL ALASKA SAT. GENERALLY BROAD STABLE
CONDITIONS PRODUCED BY WARM AIR FLOWING OVER THE COLDER BERING SEA
WATERS HAVE CAUSED WIDESPREAD LOW STRATUS AND FOG OVER MUCH OF THE
BERING SEA.

.SHORT TERM FORECAST...

SOUTHCENTRAL...
A FEW LINGERING SHOWERS SHOULD END ACROSS THE AREA OVERNIGHT.
ABUNDANT LOW LEVEL MOISTURE COMBINED WITH SUBSIDENCE FROM BUILDING
RIDGE WILL PRODUCE AREAS OF STATUS AND FOG ACROSS THE GULF AND
SOUTHCENTRAL OVERNIGHT. RAIN WILL SPREAD TO WESTERN SOUTHCENTRAL/COOK
INLET LATE SAT AFTERNOON AND MOVE EAST OVERNIGHT. WET CONDITIONS ARE
EXPECTED TO CONTINUE THROUGH THE REMAINDER OF THE WEEKEND AS MOIST SW
FLOW ALOFT CONTINUES. PRESSURE GRADIENTS WILL INCREASE ACROSS THE
REGION ON SAT AS HIGH PRESSURE HOLDS ALONG THE GULF COAST AND THE
FRONT APPROACHES FROM THE WEST. BRISK E/SE WINDS ARE EXPECTED ACROSS
TURNAGAIN ARM...KNIK VALLEY...AND SOUTH WINDS THROUGH THE COPPER
RIVER SAT AND SAT NIGHT. GRADIENTS WILL RELAX SOME ON SUN AS THE GULF
RIDGE WEAKENS.

SOUTHWEST ALASKA...
UPPER LEVEL TROUGH WILL REMAIN NEARLY STATIONARY AND THEN SHARPEN BY
TONIGHT OVER THE BERING SEA. THE RESULT WILL BE WIDESPREAD AND NEARLY
CONTINUOUS RAIN FOR THE KUSKOKWIM DELTA REGION...WHICH WILL THEN
GRADUALLY PUSH EAST LATE TONIGHT INTO SATURDAY TO AFFECT THE REST OF
THE MAINLAND SOUTHWEST ZONES. BROAD SOUTHWEST FLOW PERSISTS
THEREAFTER FOR THE REST OF THE WEEKEND BRINGING WIDESPREAD SHOWERS.
SOUTHERLY GALES ARE EXPECTED TO IMPACT THE SW COAST SAT.

BERING SEA/ALEUTIANS...
LOW PRESSURE WILL PUSH EAST ACROSS THE REGION TONIGHT AND INTO EARLY
SATURDAY...AND WILL PUSH A FRONT EAST ACROSS THE SOUTHERN BERING AND
THE ISLAND CHAIN. THE FORECAST WILL BE NOTHING OUT OF THE ORDINARY
FROM CLIMATOLOGY...WITH AREAS OF FOG AND OCCASIONAL RAIN.

.LONG TERM FORECAST...
THE AREA OF RESPONSIBILITY WILL RESIDE ON THE WET SIDE NEXT WEEK AS
WIDESPREAD ONSHORE FLOW AND EMBEDDED DISTURBANCES BRING PERIODS OF
RAIN TO MOST OF THE REGION. MORE UNCERTAINTY THAN USUAL CREEPS INTO
THE FORECAST BY MIDWEEK OUT IN THE BERING SEA...BUT AS OF NOW THIS
APPEARS TO HAVE LITTLE BEARING ON ANY CHANGES FOR THE WET FORECAST
FOR THIS COMING WEEK FOR SOUTHERN ALASKA.

.AER/ALU...WATCH/WARNING SUMMARY
PUBLIC...NONE.
MARINE...GALES 160 AND 180

FIRE WEATHER...
