SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
445 PM AKDT THU NOV 3 2011

.ANALYSIS AND UPPER LEVELS...THE AMPLIFIED AND PROGRESSIVE PATTERN
CONTINUES. THE CURRENT WEATHER MAKER IS A LARGE LOW NEARING NUNIVAK
ISLAND IN THE EASTERN BERING SEA. WATER VAPOR IMAGERY DEPICTING A
SUBTROPICAL FETCH OF MOISTURE SURGING NORTHWARD INTO THE CENTRAL AND
NORTHERN PART OF THE STATE. THE VERTICALLY STACKED LOW WILL CONTINUE
MOVING ONSHORE TONIGHT WHILE A SERIES OF VERY POTENT SHORTWAVES
ROTATE AROUND THE SOUTHERN PERIPHERY OF THE TROUGH. AHEAD OF THE
SYSTEM IS A STRONG GALE FORCE FRONTAL BOUNDARY THAT BROUGHT NEAR HIGH
WIND WARNING LEVEL WINDS TO THE ALASKA PENINSULA AND EASTERN
ALEUTIANS OVERNIGHT.

DESPITE THE VERY DRY SOUNDINGS THIS MORNING...RADAR ECHOES CONTINUE
TO FILL IN AS LIGHT SNOW FALLS FROM KACHEMAK BAY UP TO THE LOWER
SUSITNA VALLEY. WARM AIR ON THE BACKSIDE OF THE FRONT IS CHANGING
PRECIP TYPE TO RAIN OVER SOUTHWEST ALASKA ALTHOUGH COLD AIR WILL SOON
BE WRAPPING AROUND THE BACKSIDE LATER TONIGHT.

.MODEL DISCUSSION...THERE ARE SOME MINOR POSITION DIFFERENCES WITH
TRACK OF LOWS WHICH WILL MAKE LITTLE DIFFERENCE TO THE FORECAST.
OTHERWISE...MODELS ARE IN VERY GOOD AGREEMENT AND SHOW GOOD
RUN-TO-RUN CONSISTENCY. FORECAST CONFIDENCE CONTINUES TO BE ABOVE
AVERAGE.

.SHORT TERM FORECAST...

SOUTHCENTRAL ALASKA...INITIAL MOISTURE OVERRUNNING IS RESULTING IN
LIGHT SNOW ACROSS PORTIONS OF SOUTHCENTRAL ALASKA. THE DOWNSLOPE HOLE
IS BECOMING MORE EVIDENT ON THE KENAI RADAR THIS AFTERNOON AND
THE LIGHT SNOW IN ANCHORAGE IS BEGINNING TO SHUT OFF AS THE TURNAGAIN
ARM WINDS INCREASE. EXPECTING WARNING LEVEL WINDS THROUGH TURNAGAIN
ARM AND THE UPPER HILLSIDE WITH THE LOW NEAR THE KUSKOKWIM DELTA
WHICH IS A FAVORABLE POSITION FOR GAP WINDS. THE EXCEPTION WILL BE
THE NORTH AND WESTERN SUSITNA VALLEY WHERE SIGNIFICANT SNOW IS
EXPECTED THIS EVENING. MOST OF THE SNOW WILL BE JUST WEST OF THE
PARKS HIGHWAY...EXCEPT FOR A PORTION OF THE HIGHWAY NEAR CHULITNA.

WINDS DIMINISH OVERNIGHT AS AN OCCLUDED LOW DEVELOPS NEAR THE TIP OF
THE KENAI PENINSULA...SHUTTING OFF THE GRADIENT ACROSS THE CHUGACH
RANGE. THIS WILL HELP BRING ANOTHER QUICK SHOT OF LIGHT SNOW TO
ANCHORAGE AND THE MATSU VALLEY FRIDAY AFTERNOON/EVENING AS THIS
OCCLUDED LOW MOVES EAST ACROSS THE NORTHERN GULF COAST AND COLD AIR
ADVECTS BACK ACROSS THE REGION.

CONDITIONS IMPROVE SATURDAY AS A TRANSIENT UPPER RIDGE BUILDS OVER
THE REGION AND THEN QUICKLY IS PUSHED EAST AS THE NEXT SYSTEM
APPROACHES. SOUTHWEST FLOW ALOFT AND A LOW FOLLOWING A SIMILAR PATH
NEAR THE TIP OF THE KENAI SHOULD BRING ANCHORAGE ANOTHER SHOT OF
LIGHT SNOW SATURDAY NIGHT.

SOUTHWEST ALASKA...A WARM FRONT SUPPORTED BLIZZARD CONDITIONS AND
NEARLY 5 INCHES OF SNOW AT BETHEL TODAY...AND UP TO 2 INCHES OF SNOW
ACROSS THE KING SALMON REGION. HOWEVER...PRECIPITATION IS NOW MOSTLY
RAIN ACROSS MUCH OF THE SOUTHWEST MAINLAND DUE TO WARM AIR ADVECTION
BEHIND THE FRONT. CONDITIONS ARE EXPECTED TO CONTINUE TO IMPROVE
THROUGH THE NIGHT AS THE FRONT MOVES WESTWARD. FURTHER EAST...A FEW
MORE INCHES ARE POSSIBLE ACROSS THE KUSKOKWIM VALLEY THIS EVENING
BEFORE THE FRONT MOVES EASTWARD AND WEAKENS. A COLD FRONT WILL MOVE
ACROSS THE REGION EARLY TOMORROW MORNING...AND BRING THE CHANCE FOR
SNOW SHOWERS ACROSS THE SOUTHWEST MAINLAND AND RETURN MUCH COOLER
TEMPERATURES.

BERING SEA/ALEUTIANS...A LOW LEVEL JET ON THE BACKSIDE OF THE LOW
WILL BRING STRONG WINDS TO THE EASTERN ALEUTIANS THIS EVENING BEFORE
MOVING EAST AND IMPACTING THE AKPEN. CONDITIONS ARE MUCH QUIETER
ACROSS THE WESTERN BERING WHERE A SURFACE RIDGE IS BUILDING IN.
HOWEVER...A NEW LOW PRESSURE SYSTEM WILL MOVE INTO THE REGION JUST IN
TIME FOR THE WEEKEND.
