SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
500 AM AKDT THU AUG 23 2012

.ANALYSIS AND UPPER LEVELS...
WIDESPREAD RAIN IS SLOWLY MOVING FROM SOUTHWEST TO NORTHEAST OVER THS
SOUTHERN MAINLAND. PRECIPITATION IN THE SOUTHWEST IS BECOMING MORE
SHOWERY AS THE OCCLUDED FRONT HAS MOVED ACROSS THE MOUNTAINS. THE
PATTERN ALOFT LOOKS TO BE TRANSITIONING TO A MORE PROGRESSIVE ONE AS
THE UPPER LOW IN THE EASTERN GULF MOVES ASHORE THE PANHANDLE AND THE
BERING STRAIT LOW BEGINS TO SLIDE OVER THE ALASKAN PENINSULA THIS
MORNING. A STOUT 130KT JET FROM THE CHUKCHI PENINSULA DOWN THROUGH
BRISTOL BAY IS FACILITATING THIS PATTERN CHANGE. AT THE SURFACE...A
TRIPLE POINT LOW IS MOVING OVER KODIAK ISLAND WHILE WARM
ADVECTION/ISENTROPIC LIFT SPREADS A PRECIPITATION SHIELD OVER THE
BETTER PORTION OF THE SOUTH CENTRAL SANS COPPER RIVER BASIN. FURTHER
OUT WEST...A MORE ZONAL PATTER IS TAKING HOLD ATOP A SHIFTING SURFACE
RIDGE BRINGING A BREAK FROM THE SOUTHERLY FLOW AND RAIN.

.MODEL DISCUSSION...
MODELS HAVE A PRETTY GOOD HANDLE ON THE EVOLVING SITUATION WITH THE
TRIPLE POINT LOW DEVELOPING THEN LINGERING IN THE WESTERN GULF TODAY
BEFORE SHIFTING SOUTHEASTWARD. THROUGH THE WEEKEND GUIDANCE REMAINS
IN GOOD AGREEMENT SYNOPTICALLY. INTO EARLY NEXT WEEK CONFIDENCE
BREAKS DOWN AS A MORE PROGRESSIVE FLOW TAKES HOLD BRINGING
DISAGREEMENT WITH TIMING AND STRENGTH OF SHORTWAVES EMBEDDED IN THE
FASTER FLOW.

.SHORT TERM FORECAST...
SOUTHCENTRAL ALASKA...WIDESPREAD RAIN WILL CONTINUE A WARM/OCCLUDED
FRONT MOVES NORTHEAST ONTO THE MAINLAND. RAIN WILL SPREAD UP INTO THE
NORTHERN SUSITNA VALLEY AND COPPER RIVER BASIN BY LATE MORNING. AS
THE FRONT MOVES ASHORE AND WEAKENS THIS AFTERNOON. RAIN WILL LINGER
THROUGH FRIDAY MORNING ALONG GULF COAST AREAS BEFORE THE LOW MOVES
AWAY ON FRIDAY AFTERNOON. A SHORT BREAK IS IN ORDER BEFORE ANOTHER
FAST MOVING SYSTEM APPROACHES FROM THE WEST. THIS SYSTEM WILL BRING A
CHANCE FOR SHOWERS FRIDAY AFTERNOON AND EVENING FOR THE MAT-SU AND
ANCHORAGE BOWL...SPREADING EASTWARD ON SATURDAY MORNING INTO THE
COPPER RIVER BASIN AND NORTHERN GULF COAST AREAS. THE NEW PROGRESSIVE
PATTERN CONTINUES WITH ANOTHER CHANCE OF RAIN ON SUNDAY WITH YET
ANOTHER FAST MOVING SYSTEM.

SOUTHWEST ALASKA...PRECIPITATION HAS ENDED FOR THE KUSKOKWIM DELTA
REGION AND SHOWERS REMAIN FOR THE BRISTOL BAY/KUSKOKWIM VALLEY
REGIONS. LOW STRATUS AND MIST REMAIN POSSIBLE TODAY AS THE CLEARING
OF UPPER CLOUDS HAS PROMOTED LOWER DEVELOPMENT. SHOWERS WILL REMAIN
NEAR THE ALEUTIAN RANGE THROUGH THE AFTERNOON WHEN THE UPPER LOW WILL
SLIDE OVER THE ALASKAN PENINSULA INTO THE GULF. A SERIES OF QUICK
MOVING FRONTS...ONE FROM THE WEST...AND ONE FROM THE SOUTHWEST WILL
AFFECT THE REGION FOR THE WEEKEND BRINGING PERIODS OF RAIN
FRIDAY...THEN AGAIN ON SUNDAY.

BERING SEA AND ALEUTIANS...RELATIVELY QUIET WEATHER IS IN STORE FOR
THE BERING TODAY AS THE REGION LIES BETWEEN WEATHER SYSTEMS. HIGH
PRESSURE WILL SLIDE OVER THE CENTRAL PORTION OF THE CHAIN TODAY AS A
QUICK MOVING SYSTEM TO THE NORTH DRAPES A FRONT FROM WEST TO EAST BY
LATE FRIDAY MORNING...WITH LITTLE SIGNIFICANT WEATHER. THE NEXT
SYSTEM WILL DEVELOP OVER THE WESTERN ALEUTIANS ON SATURDAY...MOVING A
SURFACE LOW PRESSURE ONTO THE SOUTHWESTERN MAINLAND BY SUNDAY MORNING
AND ANOTHER FRONT DRAPED ACROSS THE BERING.

.LONG TERM FORECAST...
MODEL GUIDANCE IS BEGINNING TO COME TOGETHER ON A SOLUTION FOR THE
PHASING SYSTEM OVER THE ALEUTIANS AT THE END OF THE WEEKEND. A
PARTIAL PHASE SOLUTION LOOKS LIKELY AT THIS POINT BUT GUIDANCE IS
STILL STRUGGLING WITH THE EVOLUTION OF THE SYSTEM AS IT MOVES ONTO
THE MAINLAND. BY THE END OF NEXT WEEK GLOBAL MODELS SHOW A BROAD
TROUGH SETTING UP OVER THE BERING SEA WHICH WILL BRING A LESS
PROGRESSIVE PATTERN TO THE STATE AND SLOWER MOVING SYSTEMS.
