SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
433 PM AKDT WED SEP 23 2015

.ANALYSIS AND UPPER LEVELS...

A STEEP UPPER LEVEL TROUGH IS CURRENTLY LOCATED ACROSS EASTERN
ALASKA AND STRETCHES FROM THE ARCTIC OCEAN TO WELL INTO THE GULF
OF ALASKA. MEANWHILE A RIDGE ENCOMPASSES WESTERN ALASKA AND THE
ENTIRE BERING. AT THE SURFACE...A LOW PRESSURE SYSTEM IN THE GULF
OF ALASKA CONTINUES TO DISSIPATE AND DRIFT TO THE SOUTH AND
COASTAL GAP WINDS CONTINUE TO WEAKEN. CURRENTLY A FRONT IN THE
EASTERN BERING IS APPROACHING BRISTOL BAY AND HAS ALREADY BEEN
BRINGING LIGHT RAIN AND SNOW TO THE KUSKOKWIM DELTA. HIGH PRESSURE
IS IN PLACE OVER THE SOUTHERN BERING SEA WITH AN AXIS THROUGH THE
CENTRAL ALEUTIANS. LOW CLOUDS AND MODERATE WINDS ON THE FRINGES OF
THE HIGH.

&&

.MODEL DISCUSSION...

IN THE SHORT TERM...MODELS ARE IN GOOD AGREEMENT ON THE CONTINUED
DISSIPATION OF THE LOW IN THE GULF...AND THE CURRENT PROGRESSION
AND EVENTUAL STALL OF THE FRONT INTO BRISTOL BAY AND THE
KUSKOKWIM DELTA TOMORROW. THIS FRONT GETS REINFORCED BY AN UPPER
LOW DROPPING INTO THE NORTH SLOPE THURSDAY NIGHT. THIS UPPER LOW
ALSO BREAKS DOWN THE HIGH PRESSURE OVER THE SOUTHERN BERING. THE
SURFACE FRONT SWINGS ACROSS THE STATE THURSDAY AND FRIDAY. MODELS
REMAIN IN RELATIVELY GOOD AGREEMENT THROUGH EARLY SATURDAY AS A
LOW PRESSURE SYSTEM MOVES INTO WESTERN BERING...ELIMINATES THE
HIGH OVER THE EASTERN BERING AND CONTINUES TO PROGRESS EASTWARD TO
SOUTHWEST ALASKA BY SATURDAY MORNING.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (DAYS 1 AND 2)...
AN UPPER LEVEL RIDGE IS MOVING INTO THE REGION PRODUCING CLEAR SKIES
THROUGH THE EVENING. A LOW PRESSURE IN THE NORTHERN GULF WITH HIGH
PRESSURE INLAND AND NORTHERLY WINDS ALOFT HAVE RESULTED IN
NORTHERLY AND WESTERLY GAP WINDS ALONG THE COAST. THE COASTAL GAP
WINDS THROUGH WHITTIER...VALDEZ...AND SEWARD REGIONS WILL CONTINUE
THROUGH THE EVENING BEFORE DIMINISHING AS THE PRESSURE GRADIENTS
WEAKEN AFTER MIDNIGHT TONIGHT. THIS WILL COINCIDE WITH THE TROUGH
OF LOW PRESSURE OVER THE NORTHERN GULF CONTINUING TO MOVE
EASTWARD. BY LATE THURSDAY EVENING THERE WILL BE INCREASING CLOUD
COVER AS AN UPPER LEVEL LOW DROPS DOWN TO THE NORTH SLOPE. THIS
SYSTEM WILL BE FAST MOVING DUE TO A STRONG 140 KNOT ZONAL JET
STREAK POSITIONED THROUGH THE SEWARD PENINSULA EXTENDING EASTWARD
JUST NORTH OF COPPER RIVER BASIN. THE ASSOCIATED WEATHER FRONT
WILL BE TRACKING FROM THE SOUTHWEST INTO THE SOUTHCENTRAL ALASKA
REGION BY FRIDAY. THIS SYNOPTIC FEATURE WILL INCREASE THE PRESSURE
GRADIENTS...RESULTING IN GUSTY TURNAGAIN ARM AND THE KNIK RIVER
WINDS THROUGH FRIDAY AFTERNOON. THIS SYSTEM WILL ALSO BRING RAIN
AND A MIXTURE OF RAIN/SNOW AT HIGHER ELEVATIONS INTO THE
SOUTHCENTRAL REGION.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (DAYS 1 AND 2)...
A WET PATTERN WITH SLIGHTLY WARMER TEMPERATURES TREND THROUGH
SATURDAY. THIS EVENING...A FRONT ALONG THE KUSKOKWIM DELTA BEGINS
TO TRACK EAST AROUND MIDNIGHT. BY THURSDAY MORNING RAIN WILL TAPER
OFF TO SCATTERED SHOWERS ALONG THE KUSKOKWIM COAST WITH THE FRONT
BRINING RAIN TO THE KUSKOKWIM VALLEY ON THURSDAY. BRISTOL BAY WILL
ALSO SEE ISOLATED TO SCATTERED RAIN ACTIVITY THURSDAY ALONG THE SOUTH
END OF THE FRONT. RAIN ACTIVITY ALONG THIS FRONT DIMINISHES THURSDAY
EVENING...HOWEVER THE NEXT FRONT MOVES INTO THE SOUTHWEST LATE THURSDAY
NIGHT. ON FRIDAY THE NEW FRONT WILL HAVE AN EAST TO WEST
ORIENTATION BRINGING WIDESPREAD RAIN ACROSS THE SOUTHWEST THROUGH
SATURDAY MORNING. A SURFACE LOW PUSHES INLAND LATE SATURDAY TAPERING
RAIN OFF FROM WEST TO EAST.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (DAYS 1 AND 2)...
RAIN WILL DEVELOP ALONG A FRONT ACROSS THE EASTERN BERING TONIGHT
WITH RAIN ACTIVITY TAPERING OFF TO SCATTERED ACTIVITY ON
THURSDAY. A SURFACE RIDGE OVER THE CENTRAL ALEUTIANS THIS EVENING
KEEPS THE CENTRAL AND EASTERN ALEUTIANS ON THE DRIER SIDE UNTIL
THE NEXT FRONT MOVES UP FROM THE NORTH PACIFIC ON FRIDAY MORNING.
NORTHERN AREAS OF THE BERING WILL SEE A CLOUDY AND WETTER PATTERN
AS WEAK DISTURBANCES MOVE THROUGH NEARLY ZONAL FLOW. A WETTER
PATTERN CAN BE EXPECTED ON FRIDAY AND SATURDAY AS ACROSS THE
BERING AND ALEUTIANS ALONG A FRONT THAT MOVES UP FROM THE NORTH
PACIFIC. THE STRONGEST WINDS ARE EXPECTED ACROSS THE SOUTHERN
BERING AND ALEUTIAN CHAIN WITH THE FRONTAL PASSAGE. THIS FRONT
SHOULD BE MONITORED AS WINDS MAY BE SLIGHTLY STRONGER...UP TO
GALE STRENGTH...IF THE LOW COMES IN DEEPER THAN CURRENTLY TRENDING.

&&

.LONG TERM FORECAST (DAYS 3 THROUGH 7)...
THE PATTERN MOVING INTO THE WEEKEND LOOKS TO BE ZONAL FLOW THAT
WILL LEAD TO RAIN THROUGH MUCH OF THE WEEKEND. SATURDAY EVENING
THERE IS GOOD AGREEMENT AMONGST THE ENSEMBLES AND THE EC WITH A
SHORTWAVE MOVING THROUGH THE SOUTHERN BERING. THE SURFACE LOW
ATTACHED TO THIS FEATURE LOOKS TO BRING HEAVIER RAIN TO MAINLAND
ALASKA STARTING IN THE SOUTHWEST AND EXPANDING TO THE SOUTHCENTRAL
SUNDAY. THE GFS HAS THIS FEATURE AS WELL BUT IT REMAINED SLOWERTHAN
THE OTHER GUIDANCE. HOWEVER...THE 12Z GFS IS CATCHING UP TO THE
OTHERS GIVING MORE CONFIDENCE IN RAIN OVER THE WEEKEND.

THE PATTERN AFTER THE FRONT MOVES IN LEADS TO INCONSISTENCIES
AMONGST THE MODELS. ALL HAVE AN ARCTIC TROUGH EXTENDING DOWN
THROUGH THE BERING THAT MOVES IN OVER MAINLAND ALASKA EARLY NEXT
WEEK BRINGING IN A FAIR AMOUNT OF COLD AIR DOWN WITH IT. THE
ENSEMBLES AND THE EC HAVE THE PREVIOUS SURFACE LOW TRACKING NORTH
AT THIS SAME TIME KEEPING MUCH OF THE SOUTHCENTRAL RELATIVELY DRY
BUT ALSO BRINGING IN COLDER TEMPERATURES THROUGHOUT THE
SOUTHCENTRAL. THE GFS PUSHES THE TROUGH FURTHER SOUTH FORMING A
NEW LOW OVER THE SOUTHCENTRAL AND GIVING A POSSIBILITY OF SNOW
FOR TUESDAY AFTER THE RAIN MOVES THROUGH. AT THIS POINT THERE IS
HIGH UNCERTAINTY AND THE GENERAL CONSENSUS OF THE MODELS IS THE
WARMER TRACK KEEPING THINGS ALL RAIN FOR THE SOUTHCENTRAL.
