SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
448 AM AKST SAT NOV 7 2015

.ANALYSIS AND UPPER LEVELS...
THE LONGWAVE PATTERN OVER THE GREAT LAND IS BEGINNING TO LOOK A
BIT MORE PROGRESSIVE THIS MORNING. THE BIG UPPER LOW RESPONSIBLE
FOR THE WEATHER OF THE PAST FEW DAYS IS WEAKENING INTO A BROAD
TROUGH...AND BEGINNING TO PROPAGATE EASTWARD AS THE EAST ASIAN
JET STRENGTHENS (AROUND 160 KTS) OVER THE BERING SEA. A LINGERING
TROUGH OVER THE COPPER RIVER BASIN AND PRINCE WILLIAM SOUND IS THE
FOCUS FOR ANY PRECIPITATION LEFT OVER WITH THIS SYSTEM. LOW CLOUDS
AND FOG DEVELOPED AROUND THE COOK INLET REGION LAST EVENING IN
RESPONSE TO MELTING SNOW AND SLIGHT CLEARING ALOFT/SURFACE
COOLING...BUT REMAINS PATCHY IN COVERAGE AT THE MOMENT.

FURTHER OUT WEST...A WEAK FRONTAL BOUNDARY ON THE FRONT EDGE OF
THE INCOMING JET IS PUSHING ONTO THE KUSKOKWIM DELTA AND BRISTOL
BAY BRINGING A SHOT OF LIGHT SNOW TO THE REGION. A LARGE SURGE OF
SUB-TROPICAL MOISTURE ALOFT IS EVIDENT ON WATER VAPOR IMAGERY
ASSOCIATED WITH A DISTURBANCE BEGINNING TO PHASE WITH THE NORTHERN
STREAM AND KAMCHATKA UPPER TROUGH. THOSE TWO SYSTEMS COMING
TOGETHER LOOK TO BE THE FOCUS FOR ACTIVE WEATHER ACROSS BOTH
DOMAINS IN THE COMING DAYS.

&&

.MODEL DISCUSSION...
THE LARGE SCALE SYNOPTIC PATTERN IS PRETTY WELL AGREED UPON BY
GUIDANCE. THE CURRENT KAMCHATKA UPPER LOW WILL DEEPEN AND MOVE
EASTWARD AS THE EAST ASIAN JET PUNCHES IN AND A SEPARATE PIECE OF
ENERGY FROM THE NORTH PACIFIC PHASES INTO THE TROUGH. GIVEN THE
DYNAMIC NATURE OF THE SYSTEM GUIDANCE IS NOT IN AGREEMENT OF
SPECIFICS LIKE STRENGTH AND EXACT LOCATION...BUT THERE IS PRETTY
HIGH CONFIDENCE OF A SEASONABLY STRONG LOW PRESSURE (950 MB RANGE
LATE TONIGHT) IN THE NORTHERN BERING SEA. AS ALWAYS...THE DEVIL IS
IN THE DETAILS...WHILE THE OCCLUDED FRONTAL TIMING IS PRETTY WELL
AGREED UPON (MOVING FROM WEST TO EAST ACROSS THE SOUTHERN MAINLAND
ON SUNDAY)...THE LIKELY FORMATION OF A TRIPLE POINT LOW IN THE
COOK INLET REGION/NORTHERN GULF ON SUNDAY AFTERNOON IS NOT WELL
AGREED UPON AND CAN HAVE A HUGE EFFECT ON THE FORECAST. SOME
SOLUTIONS (HIGHER RESOLUTION) ARE BRINGING AT LEAST A PORTION OF
THE SURFACE LOW UP INTO COOK INLET. CLIMATOLOGY OF THESE SYSTEMS
WOULD SUPPORT A KODIAK TO PRINCE WILLIAM SOUND TRACK. THE EXACT
TRACK WILL AFFECT SNOWFALL AMOUNTS/TIMING...TURNAGAIN
ARM/DOWNSLOPE WIND STRENGTH/BENDING...AND PRECIPITATION TYPE.
ABOUT THE ONLY ABSOLUTE WITH THIS SYSTEM SO FAR IS THAT IT WILL BE
A QUICK HITTER...THE FAST/PROGRESSIVE SOUTHWESTERLY FLOW ALOFT
WILL KEEP THIS SYSTEM TRUCKING ON THROUGH SOUTHCENTRAL ALASKA.
WEST DOMAIN PREFERRED THE NAM/EC WHILE THE EAST DOMAIN FAVORED THE
GFS.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (DAYS 1 AND 2)...
THE UPPER LEVEL TROUGH THAT IS OVER SOUTH CENTRAL ALASKA WILL
CONTINUE TO WEAKEN TODAY AND TONIGHT...SHIFTING VERY SLOWLY
EASTWARD. THE SURFACE LOW WILL REMAIN NEAR YAKUTAT AND OUTFLOW
WINDS WILL CONTINUE INTO TONIGHT AS HIGH PRESSURE BUILDS OVER
SOUTH CENTRAL BEHIND THE TROUGH. THE UPPER TROUGH WILL EXIT INTO
CANADA SUNDAY MORNING. A VERY LARGE UPPER LOW COVERING THE BERING
SEA BY SUNDAY WILL SEND A FRONT INTO SOUTH CENTRAL SUNDAY AND
SUNDAY NIGHT. THE FRONT WILL BE VERY WELL OCCLUDED BY THE TIME IT
GETS INLAND LATER SUNDAY. A TRIPLE POINT LOW WILL DEVELOP NEAR THE
BARREN ISLANDS SUNDAY AFTERNOON AND PUSH INTO PRINCE WILLIAM SOUND
AROUND MIDNIGHT. THE STRENGTH AND SPEED OF THIS SYSTEM WILL
PROVIDE MOST AREAS WITH A BRIEF BURST OF HEAVY PRECIPITATION. THIS
WILL LIKELY BE IN THE FORM OF SNOW FOR MOST INLAND AREAS DUE TO
THE HIGHLY OCCLUDED NATURE OF THE FRONT (NOT A WARM FRONT) AND THE
HEAVY PRECIPITATION. EXCEPTIONS TO THIS WILL BE BE COASTAL AREAS
AND THE WESTERN KENAI PENINSULA SOUTH OF ABOUT SOLDOTNA WHERE
ENOUGH WARM AIR SNEAKS NORTH TO MAKE FOR A LIKELIHOOD OF A MIX
WITH RAIN...OR POSSIBLY ALL RAIN. WITH THE FRONT AND TRIPLE POINT
LOW RACING ALONG...THIS WILL ALSO LEAD TO RAPIDLY SHIFTING WINDS.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (DAYS 1 AND 2)...

A BAND OF SNOW IS CURRENTLY PUSHING ACROSS THE KUSKOKWIM DELTA AND
MIXES WITH RAIN ACROSS THE WESTERN CAPES OF THE BRISTOL BAY AREA.
IT LOOKS LIKE THIS BAND WILL HOLD TOGETHER THROUGH THE MORNING
HOURS AND BRING SOME MINOR SNOW ACCUMULATIONS TO THE KUSKOKWIM
DELTA AND INLAND LOCATIONS OF THE BRISTOL BAY AREA. THINGS BEGIN
TO GET A BIT TRICKY THIS AFTERNOON AS A VERY WARM AIR MASS OVER
THE BERING SEA BEGINS TO ADVECT INLAND ACROSS SOUTHWEST ALASKA.
PRECIPITATION WILL HAVE TAPERED OFF BY THE TIME THIS WARMER AIR
BEGINS TO SITUATE ITSELF. HOWEVER...A VERY POTENT WARM FRONT WILL
SLAM THE WESTERN COAST BY LATE TONIGHT/EARLY SUNDAY MORNING.
PRECIPITATION ASSOCIATED WITH THIS FRONT WILL FALL AS RAIN AS 850
MB TEMPERATURES RISE TO NEAR ZERO DEGREES RIGHT AS THE FRONT MOVES
INLAND. THE FRONT WILL QUICKLY OCCLUDE WHICH WILL ALLOW COLDER AIR
TO QUICKLY REPLACE THE WARMER AIR MASS. THIS WILL FAVOR A
TRANSITION FROM RAIN TO SNOW DURING THE DAY SUNDAY. SNOW
ACCUMULATION WILL LIKELY BE MINOR EXCEPT ALONG UPSLOPE LOCATIONS
ALONG THE AHKLUN MOUNTAINS...THE ALASKA RANGE AND THE ALEUTIAN
RANGE WHERE 2-4 INCHES OF SNOW LOOKS POSSIBLE. A LONGWAVE TROUGH
WILL ENCOMPASS MUCH OF ALASKA COME LATE SUNDAY AND IT APPEARS THAT
SCATTERED TO NUMEROUS SNOW SHOWERS WILL CONTINUE ACROSS SOUTHWEST
ALASKA FOR QUITE SOME TIME.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (DAYS 1 AND 2)...

A RAPIDLY DEVELOPING LOW LOOKS POISED TO DEVELOP DURING THE DAY
TODAY OVER THE WESTERN BERING SEA AS AN EXTREMELY POTENT JET
STREAK INTERACTS WITH A SFC LOW. AS WITH ALL RAPIDLY DEVELOPING
CYCLONES...STRONG WINDS WILL DEVELOP NEAR THE LOW CENTER DUE TO A
TIGHT PRESSURE GRADIENT AS THE LOW STRENGTHENS. THIS WILL BRING
SOME STORM FORCE WINDS TO THE NORTHERN BERING SEA AND WIDESPREAD
GALES TO THE REMAINDER OF THE BERING SEA. A VERY POTENT WARM FRONT
WILL QUICKLY PUSH ACROSS THE BERING ON SUNDAY AND BRING UNUSUALLY
WARM TEMPERATURES TO THE ALEUTIAN ISLANDS. HOWEVER...COLD AIR
WRAPPING IN BEHIND THE LOW WILL BRING SOME OF THE SEASON'S COLDEST
TEMPERATURES OBSERVED ACROSS MUCH OF THE BERING SEA BY LATE
SUNDAY. THIS SHOULD ALLOW SOME OF THE RAIN SHOWERS TO MIX WITH OR
CHANGE TO SNOW...ESPECIALLY OVER THE WESTERN AND CENTRAL
ALEUTIANS. AS MENTIONED IN THE PREVIOUS SECTION...A LONGWAVE
TROUGH WILL BE ANCHORED OVER THE REGION WHICH SHOULD KEEP
SCATTERED TO NUMEROUS RAIN AND SNOW SHOULD OVER THE BERING SEA AND
ALEUTIAN ISLANDS FOR QUITE SOME TIME.

&&

.LONG TERM FORECAST (DAYS 3 THROUGH 7)...

AN ACTIVE WEATHER PATTERN PERSISTS FOR SOUTHCENTRAL THROUGH THE
WORK WEEK AFTER THE SUNDAY/SUNDAY NIGHT STORM. NUMEROUS
DISTURBANCES WILL ROTATE THROUGH AND COMBINE WITH STRONG ONSHORE
FLOW TO PUSH A HIGH-MOISTURE AND LOW STABILITY REGIME
INLAND...ALLOWING FOR LIGHT SNOW TO OCCUR INTERMITTENTLY
ESPECIALLY IN UPSLOPE AREAS ALONG AND NEAR THE TALKEETNA
MOUNTAINS...INCLUDING THE MATANUSKA VALLEY AND NORTHERN AND
EASTERN SUSITNA VALLEY. TOWARD ANCHORAGE...A STEADY BUT NOT
PARTICULARLY STRONG SOUTHEASTERLY WIND OUT OF TURNAGAIN ARM WILL
ALLOW FOR TEMPERATURES TO WARM ABOVE FREEZING AT TIMES ESPECIALLY
FOR PARTS OF ANCHORAGE MONDAY INTO MONDAY NIGHT. BY MID TO LATE
WEEK...A STRONG LOW MOVING WEST TO EAST FROM THE BERING ACROSS THE
CENTRAL GULF WILL HELP TO USHER COLD AIR INTO THE SOUTHERN
MAINLAND...AS WELL AS STRENGTHEN NORTHERLY OFFSHORE WINDS THROUGH
THE TERRAIN GAPS THROUGH THE MOUNTAIN RANGES.

TOWARD SOUTHWEST ALASKA AND THE BERING SEA...WIDESPREAD WEST TO
NORTHWESTERLY WINDS OF 30 TO 35 KNOTS AND SCATTERED TO NUMEROUS
SHOWERS ACROSS THE REGION WILL GIVE WAY TO A HIGH-END GALE-FORCE
LOW THAT MOVES QUICKLY WEST TO EAST ACROSS THE ALEUTIANS LATE
TUESDAY THROUGH LATE WEDNESDAY.
