SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
510 AM AKST MON FEB 22 2016

.ANALYSIS AND UPPER LEVELS...
NOW THAT THE LAST FRONT AND SHORTWAVE HAVE MOVED THROUGH THE
PATTERN ALOFT LOOKS MUCH MORE BENIGN. BROAD AND WEAK TROUGHING
SITS OVER MUCH OF THE BERING SEA WITH THE REMNANT UPPER LOW
SPINNING OVER BRISTOL BAY...HEADING INLAND EARLY THIS MORNING.
GENERALLY THE UPPER LEVEL JET IS SOUTH OF THE ALEUTIANS BUT NOT AS
FAR SOUTH AS MOST OF THE WINTER. THERE ARE TWO STRONGER UPPER
LEVEL SYSTEMS...ONE JUST SOUTH OF THE WESTERN ALEUTIANS CURRENTLY
DEVELOPING A SURFACE SYSTEM AS WELL...AND A CUT OFF LOW AROUND 40N
SOUTH OF KODIAK ISLAND. THE UPPER LOW CURRENTLY MOVING INLAND HAS
USED UP MOST OF ITS ENERGY...THOUGH WITH SUCH COLD TEMPERATURES
ALOFT AND A FAIRLY WARM AIR MASS AT THE SURFACE...LOTS OF
INSTABILITY IS PRESENT. THAT INSTABILITY IS THE FOCUS FOR
PLENTIFUL SHOWER ACTIVITY...MAINLY ALONG THE COAST THIS MORNING.
SOME LIGHTNING STRIKES HAVE BEEN DETECTED BY SATELLITE ALONG THE
COAST OF WESTERN PRINCE WILLIAM SOUND. THE UPSLOPE FLOW ON THE
TERRAIN IS PROVIDING JUST ENOUGH LIFT TO ENHANCE THE CONVECTIVE
SHOWERS. ON THE OTHER SIDE OF THE TERRAIN...THE COOK INLET REGION
REMAINS MOSTLY DOWNSLOPED AND DRY WITH SOUTHEASTERLY WINDS
LINGERING ALONG THE TERRAIN SAVE FOR KACHEMAK BAY WHERE SOME
SHOWERS ARE MAKING IT OVER THE MOUNTAINS.

&&

.MODEL DISCUSSION...

THE NAM SEEMED TO VERIFY THE BEST WITH REGARDS TO THE LAST
EVENT...AND THE MESOSCALE MODELS PERFORMED VERY WELL WITH THIS
VERY ANOMALOUS EVENT COMPARED TO GLOBAL GUIDANCE. NOW THAT THE
PATTERN HAS SETTLED A LITTLE BIT AND BAROCLINIC ENERGY HAS BEEN
USED UP...GUIDANCE HAS FAR LESS DISCREPANCIES THAN THE PREVIOUS
FEW DAYS. THERE IS GOOD AGREEMENT WITH THE SHOWERY PATTERN
CONTINUING WHILE THE COLD AIR STICKS AROUND TODAY. BEYOND
THAT...THE CUT OFF LOW IN THE MID-LATITUDES WILL GET PICKED UP BY
THE ALEUTIAN LOW...SENDING A FRONT UP INTO THE GULF. AGREEMENT IS
PRETTY GOOD ON TIMING OF THIS FRONT AND SURFACE LOW PRESSURE.
LOOKS AT THIS POINT TO BE A GALE/STORM FORCE FRONT MOVING INTO THE
NORTHERN GULF BY TUESDAY AFTERNOON.

&&

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

BROAD AND UNSTABLE CYCLONIC FLOW ALOFT OVER THE GULF AND
SOUTHCENTRAL WILL CONTINUE SHOWERS ACROSS MUCH OF THE FORECAST
AREA. A COLD POOL OF AIR AT 500 MB (-37C TO -38C) HAS HELP TO
DESTABILIZE THE ATMOSPHERE AND HAS GIVEN RISE TO ISOLATED
THUNDERSTORMS ACROSS PORTIONS OF THE GULF THIS MORNING....WHICH
COULD CONTINUE THROUGH THIS MORNING. CONDITIONS BECOME MORE
STABLE TONIGHT AS TEMPERATURES WARM AIR ALOFT. ON TUE THE FOCUS
SHIFTS TO A DEVELOPING LOW HEADING TOWARD THE ALASKA PENINSULA AND
ITS ASSOCIATED FRONT MOVING NORTH IN THE GULF. WINDS IN ADVANCE
AND ALONG THE FRONTAL BOUNDARY SHOULD BRING GALES TO STORM FORCE
WINDS TO THE NORTHERN GULF TUE THROUGH TUE NIGHT. THIS FRONT WILL
ALSO BRING A FAIR AMOUNT OF PRECIPITATION TO THE COASTS WHICH
LOOKS LIKE IT WILL LEAN TOWARD RAIN AS 850 MB TEMPS SHOULD BE
WARMER ON THIS ROUND. CURRENT MODEL PROJECTIONS ALSO SHOW A MORE
CLASSIC DOWNSLOPE SIGNATURE TO THE LEE OF THE CHUGACH/KENAI
MOUNTAINS.

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

SHOWER ACTIVITY ACROSS THE SOUTHWEST MAINLAND WILL CONTINUE TO
TAPER OFF THROUGH THE MORNING HOURS AS A DECAYING AREA OF LOW
PRESSURE IN BRISTOL BAY CONTINUES TO FIZZLE OUT. THE BULK OF THE
REMAINING SHOWERS WILL BE LARGELY CONFINED TO A LINE EXTENDING
FROM THE WESTERN CAPES OF THE BRISTOL BAY AREA EASTWARD TOWARD THE
ALASKA AND ALEUTIAN RANGES. BY THIS EVENING...SHOWERS WILL BECOME
WIDELY SCATTERED WITH THE LOSS OF SYNOPTIC FORCING...LEAVING
UPSLOPE LOCATIONS AS THE MOST LIKELY AREAS TO SEE A BRIEF SNOW
SHOWER OR TWO. PATCHY FOG (VSBY POSSIBLY LESS THAN ONE MILE) IS
EXPECTED TO DEVELOP MID-MORNING ACROSS THE KUSKOKWIM DELTA AND
WESTERN CAPES AS FLOW BECOMES WEAK FROM THE SOUTH. THIS ONSHORE
FLOW SHOULD PRODUCE FAVORABLE (ALBEIT SHALLOW) HYDROLAPSES TO
SUPPORT FOG AND LOW STRATUS. THERE APPEARS THAT ENOUGH MIXING
DURING THE AFTERNOON SHOULD LIFT THE FOG BUT LOW CLOUDS LOOK TO BE
LIKELY THROUGH MUCH OF THE DAY. ANOTHER SHOT OF PRECIPITATION WILL
BE OBSERVED TUESDAY AFTERNOON AS AN AREA OF LOW PRESSURE IN THE
NORTHERN PACIFIC SWINGS A FRONT NORTH TOWARD THE ALASKA PENINSULA.
THE FRONTAL ORIENTATION WILL BE LARGELY NORTHWEST/SOUTHEAST
ORIENTED WHICH LOOKS TO KEEP LOCATIONS ON THE LEE SIDE OF THE
ALEUTIAN RAGE (KING SALMON AND SIMILAR LOCATIONS) ON THE DRY SIDE.
THIS SHOULD ALSO PRODUCE GUSTY WINDS RANGING FROM 30 TO 45 MPH
ACROSS THE BRISTOL BAY AREA.

&&

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

AN AREA OF LOW PRESSURE SKIRTING SOUTH OF THE WESTERN AND CENTRAL
ALEUTIANS WILL PUSH A FRONT ACROSS THE WESTERN AND CENTRAL
ALEUTIANS THROUGH EARLY TUESDAY MORNING. ONE CONCERN WITH THE
FRONT THIS MORNING WILL BE THE POTENTIAL FOR BLOWING SNOW (MAINLY
NEAR ADAK) AS TEMPERATURES WILL REMAIN NEAR OR JUST BELOW FREEZING
AT THE ONSET OF THE PRECIPITATION. GUSTY WINDS UP TO 45 MPH WILL
BE OBSERVED BY MIDDAY AND WILL COINCIDE WITH THE SNOWFALL OVER
THE REGION. HOWEVER...TEMPERATURES ARE EXPECTED TO WARM INTO THE
UPPER 30S IN THE AFTERNOON WITH DECENT SOUTHERLY WARM AIR
ADVECTION WHICH SHOULD LIMIT BOTH SNOW ACCUMULATION AS WELL AS
VISIBILITY REDUCTION FROM THE BLOWING SNOW. THUS...NO ADVISORY
WILL BE ISSUED WITH THE MORNING PACKAGE BUT VISIBILITIES NEAR ADAK
COULD DROP TO A HALF MILE BRIEFLY AT THE INITIAL ONSET OF SNOWFALL.

&&

.LONG TERM FORECAST (DAYS 3 THROUGH 7)...
FORECAST GUIDANCE REMAINS IN GOOD AGREEMENT WITH A BROAD UPPER
LEVEL TROUGH REMAINING OVER MUCH OF THE BERING/ALEUTIANS AND PART
OF THE SOUTHERN MAINLAND. TO THE EAST...A STOUT BLOCKING RIDGE
OVER SOUTHEAST ALASKA WILL GET PUSHED FURTHER TO THE EAST WITH
EACH WAVE THAT TRACKS UP THE WESTERN FLANK OF THE RIDGE THROUGH
THE END OF THE WEEK. THERE IS LITTLE CHANGE IN FORECAST REASONING
FROM YESTERDAYS PACKAGE...WITH MULTIPLE WAVES ROTATING THROUGH
THE TROUGH AND EVENTUALLY TRACKING INTO PARTS OF THE SOUTHERN
MAINLAND THROUGH NEXT WEEKEND.

THE MAIN WEATHER FEATURE OF THE EXTENDED IS THE LARGE NORTH
PACIFIC LOW SOUTH OF COLD BAY WEDNESDAY MORNING. THE STRONG FRONT
ASSOCIATED WITH THIS LOW IS EXPECTED TO ROTATE NORTHWARD INTO THE
NORTHERN GULF COAST WEDNESDAY MORNING...AND PUSH FURTHER INLAND BY
LATE WEDNESDAY NIGHT. THIS WILL PRODUCE WIDESPREAD PRECIPITATION
AND GUSTY WINDS MAINLY ALONG THE EASTERN KENAI AND AREAS
SURROUNDING PRINCE WILLIAM SOUND. THE AREAS ON THE LEE SIDE OF THE
CHUGACH AND KENAI RANGES SHOULD REMAIN MOSTLY DRY FROM
DOWNSLOPING...WITH THE POTENTIAL FOR SOME SPILL-OVER AROUND THE
UPPER COOK INLET AREA DURING THE DAY WEDNESDAY. THIS FRONT IS WILL
HAVE A GOOD DEAL OF MOISTURE ASSOCIATED WITH IT...THUS A SECOND
SHOT OF POTENTIALLY HEAVY PRECIPITATION IS EXPECTED FOR THE
NORTHERN GULF COAST WITH RAIN ALONG THE IMMEDIATE COAST AND SNOW
INLAND AND AT HIGHER ELEVATIONS.

OUT WEST...SOUTHEAST FLOW OVER THE ALEUTIAN RANGE WILL CAUSE SOME
GUSTY WINDS AND DOWNSLOPING ALONG THE RANGE AND ALASKA PENINSULA
WEDNESDAY. AS THE LARGE LOW MENTIONED ABOVE SLOWLY DRIFTS
WESTWARD OVER DUTCH HARBOR BY THE END OF THE WEEK...CONDITIONS
OVER THE SW MAINLAND WILL BECOME MORE SHOWERS AND HAVE A SLIGHTLY
STRONGER OFFSHORE FLOW. MODELS ARE SHOWING A SECOND LOW DEVELOPING
OFF THE BASE OF THE TROUGH FRIDAY...AND TRACKING TOWARD THE AKPEN
BETWEEN SATURDAY AFTERNOON AND SUNDAY MORNING. THIS SYSTEM IS
SHOWING SIGNS OF PHASING WITH THE PREVIOUS LOW OVER THE EASTERN
ALEUTIANS OVER NEXT WEEKEND...KEEPING WET AND WINDY CONDITIONS
OVER A FAIR STRETCH OF THE AREA THROUGH NEXT WEEKEND. WEST OF
THESE TWO SYSTEM HOWEVER...COOL NORTHERLY FLOW WILL PERSIST OVER A
GOOD PORTION OF THE CENTRAL AND WESTERN BERING/ALEUTIANS. THIS
WILL KEEP SHOWERY CONDITIONS AND SOME GUSTY WINDS OVER MUCH OF
THE AREA THROUGH NEXT WEEKEND.
