SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
431 PM AKST SUN DEC 20 2015

.ANALYSIS AND UPPER LEVELS...

THE UPPER LEVEL PATTERN IS SIMILAR TO YESTERDAYS WITH A STRONG
JET STREAM JUST SOUTH OF THE AREA AND A BROAD AREA OF LOW PRESSURE
OVER THE STATE. THE UPPER LOW CENTER IS LOCATED OVER KAMCHATKA AND
THIS ENERGY FROM THE JET STREAM IS FUELING THE RAPID DEVELOPMENT
OF THE LOW MOVING INTO THE WESTERN ALEUTIANS. THE JET IS A VERY
STRONG ONE WITH 250 MB WIND SPEEDS IN EXCESS OF 200 KT. SINCE THE
JET IS EXPECTED TO REMAIN SOUTH OF THE AREA IT WILL FAVOR THE
DEVELOPMENT OF TRIPLE POINT LOWS ALONG THE FRONT IS STRETCHING
OVER THE CENTRAL ALEUTIANS AND HEADING TOWARD THE ALASKA
PENINSULA. THIS PATTERN WILL ALSO KEEP COLDER AIR OVER THE STATE
AND PREVENT WARMER PACIFIC AIR OUT OF MAINLAND ALASKA.

&&

.MODEL DISCUSSION...

MODEL INITIALIZATION WAS VERY GOOD FROM THIS MORNINGS RUNS. THE
MODELS ALL HAVE THE SAME BASIC IDEA OF TAKING THE LOW MOVING INTO
THE BERING SEA AND ELONGATING IT WITH A PARENT LOW BECOMING QUASI
STATIONARY AND A TRIPLE POINT LOW DEVELOPING OVER THE EASTER
ALEUTIANS. AS IS TYPICAL IN THIS SORT OF PATTERN IS THAT THE
MODELS HAVE DIFFICULTY WITH THE PLACEMENT OF BOTH OF THOSE
FEATURES. FOR AREAS THAT ARE TO THE NORTHEAST OF THE FRONT...WHICH
IS MOST OF THE FORECAST AREA...THIS WILL NOT HAVE A LARGE IMPACT.
THE AREAS THIS WILL IMPACT THE MOST IS THE CENTRAL AND WESTERN
ALEUTIANS AND BERING SEA WITH THE CENTRAL ALEUTIANS FROM ADAK
EASTWARD HAVING THE MOST AMOUNT OF UNCERTAINTY.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (DAYS 1 AND 2)...
AN UPPER LEVEL RIDGE WILL BUILD OVER THE SOUTHCENTRAL REGION
TONIGHT. PATCHY FOG WILL DEVELOP DURING THE LATE EVENING EXTENDING
INTO EARLY MONDAY MORNING. THERE WILL BE CONTINUED OFFSHORE WINDS
WITH GUSTY GAP WINDS THROUGH WHITTIER...PORTAGE AND THE THOMPSON
PASS REGION. THESE WINDS WILL GRADUALLY DIMINISH AFTER MIDNIGHT
TONIGHT DUE TO THE WEAKENING OF THE PRESSURE GRADIENT. THE COLDEST
TEMPERATURES WILL REMAIN THROUGH THE COPPER RIVER BASIN AS COLDER
AIR FILTERS IN FROM THE NORTH COINCIDING WITH THE NORTHERLY
OFFSHORE FLOW. THERE IS AN UPSTREAM WEAK SHORTWAVE ALOFT THAT
WILL MOVE FROM THE KODIAK REGION THIS EVENING NORTHWARD THROUGH
MONDAY. THIS WILL BRING A SHOWERY WEATHER REGIME WITH PRECIPITATION
FALLING AS ALL SNOW THROUGH THE SOUTHCENTRAL REGION.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (DAYS 1 AND 2)...
THE SURFACE LOW ACROSS THE KUSKOKWIM DELTA MOVES SOUTHEAST
OVERNIGHT. SNOW WILL CONTINUE TO DEVELOP AROUND THE LOW CENTER
TONIGHT WITH ONLY MINOR ACCUMULATIONS EXPECTED ACROSS THE
KUSKOKWIM DELTA. THIS SYSTEM LOSES ORGANIZATION AS IT NEARS THE
ALEUTIAN RANGE EARLY MONDAY MORNING. AREAS OF FOG WILL DEVELOP
AGAIN TONIGHT ACROSS VALLEYS WITH ABUNDANT LOW LEVEL MOISTURE AND
A WEAK TEMPERATURE INVERSION JUST OFF THE SURFACE. FOG IMPROVES
LATER ON MONDAY AS A LIGHT NORTH FLOW PATTERN SETS UP WITH DRIER
CONDITIONS INTO TUESDAY.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (DAYS 1 AND 2)...
TONIGHT LOW PRESSURE DEEPENS NORTH OF KISKA BRINGING STRONG GUSTY
WINDS OUT OF THE WEST ACROSS THE CENTRAL ALEUTIANS. THIS LOW
BEGINS TO LIFT TO THE NORTHERN BERING AFTER MIDNIGHT AND USHERS
COLDER AIR ACROSS THE CHAIN INTO MONDAY. FORECAST WINDS WERE
INCREASED ACROSS THE EASTERN ALEUTIANS AND ALASKA PENINSULA
THROUGH MONDAY NIGHT AS THE PRESSURE GRADIENT TIGHTENS BETWEEN
HIGH PRESSURE ACROSS THE NORTHERN PACIFIC AND LOW PRESSURE IN THE
BERING. WINDS SHOULD BE MONITORED FOR CHANGES ACROSS THE
SOUTHEASTERN BERING...EASTERN ALEUTIANS AND ALASKA PENINSULA...AS
THEY MAY BE HIGHER THAN CURRENTLY PROJECTED ON MONDAY IF A TRIPLE
POINT LOW DEVELOPS IN THE VICINITY. OTHERWISE...ZONAL FLOW BRINGS
A WESTERLY FLOW WITH SNOW SHOWERS ACROSS THE BERING THROUGH
TUESDAY NIGHT.

&&

.LONG TERM FORECAST (DAYS 3 THROUGH 7)...
WHILE THERE IS GOOD MODEL AGREEMENT IN THE IDEA OF A STRONG LOW
LIFTING NORTH ACROSS THE ALEUTIANS OUT NEAR KISKA ISLAND AROUND
WEDNESDAY...THERE IS HOWEVER SIGNIFICANT DISAGREEMENT IN BOTH THE
TIMING AND HOW FAR NORTH THE LOW MAKES IT UP INTO THE BERING. THE
COMPLEXITIES APPEAR TO BE ARISING FROM AN INTERESTING BUCKLING IN
THE JET STREAM AROUND A FAST MOVING UPPER LEVEL RIDGE EMBEDDED IN
THE BROADER AND RATHER STRONG WESTERLY JET STREAM TO THE SOUTH. A
STRONG JET STREAK ON THE UPSTREAM SIDE OF THE RIDGE BECOMES
ORIENTED SOUTH TO NORTH BETWEEN 40 AND 50N ALONG 180 EARLY
WEDNESDAY MORNING. IT IS THIS JET STREAK THAT PROPELS THE RAPIDLY
DEEPENING SURFACE LOW UP NORTH INTO THE BERING. THE QUESTION IS
HOW FAR NORTH THE LOW WILL MAKE IT BEFORE THE RIDGE BUCKLES AND
AMPLIFIES ENOUGH TO BE UNDERCUT BY THE LARGER JET COMING IN FROM
THE WEST BETWEEN 35 AND 40N RESULTING IN THE ENTIRE FEATURE BEING SWEPT
OFF TO THE EAST. BASED ON THE POSITION OF THE JET STREAK...WHICH
IS SIGNIFICANTLY MORE CONSISTENT BETWEEN THE VARIOUS MODELS THAN
THE SURFACE FEATURES...IT LOOKS LIKE THE SURFACE LOW SHOULD MAKE
IT NORTH TO AROUND 54N WEDNESDAY NIGHT BEFORE IT PUSHES OFF TO
THE EAST SOUTHEAST AS IT FILLS THURSDAY AND FRIDAY.

MEANWHILE FURTHER TO THE EAST COLD AIR BUILDS OVER MAINLAND
ALASKA THROUGH MIDWEEK AS A COLD UPPER LEVEL LOW CROSSES THE
NORTHERN PORTIONS OF THE STATE. AN ASSOCIATED SHORTWAVE TROUGH
ROTATES ACROSS SOUTHWEST ALASKA WEDNESDAY AFTERNOON AND EVENING
AND OVER SOUTH CENTRAL ALASKA WEDNESDAY NIGHT AND THURSDAY
MORNING. ASIDE FROM SOME ISOLATED TO POSSIBLY SCATTERED MOUNTAIN
SHOWERS THE MAIN IMPACT OF THE TROUGH WILL BE TO PUSH MORE COLD
INTERIOR AIR INTO THE AREA AND FURTHER STRENGTHEN OFFSHORE GAP
WINDS.

THE UPPER LEVEL LOW COMING IN FROM THE WEST WILL REACH THE WESTERN
TIP OF THE ALASKA PENINSULA AROUND FRIDAY AFTERNOON WITH THE
ASSOCIATED FRONTAL SYSTEM STRETCHING FROM BRISTOL BAY ACROSS THE
NORTHERN ALASKA PENINSULA...KODIAK ISLAND AND THE SOUTHERN TIP OF
THE KENAI PENINSULA AND INTO THE GULF. AS WITH THE MIDWEEK SYSTEM
THERE IS ALSO SIGNIFICANT UNCERTAINTY OF REGARDING HOW FAR NORTH
THIS SYSTEM WILL MAKE IT. CURRENTLY THINKING THAT IT WILL BRUSH
THE NORTHERN GULF COAST BUT THE COMBINATION OF THE OFFSHORE FLOW
AND THE FRONT SHEARING APART AS IT GETS MORE DISTANT FROM THE LOW
WILL KEEP THE MOISTURE FROM MAKING IT VERY FAR INLAND.
