SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
445 PM AKDT SAT APR 11 2015

.ANALYSIS AND UPPER LEVELS...
BROAD CYCLONIC FLOW ASSOCIATED UPPER LOW CENTERS OVER THE EASTERN
BERING SEA AND THE NORTHERN GULF CONTINUE SHOWER ACTIVITY OVER
MUCH OF THE AOR. COLD AIR ASSOCIATED WITH THE UPPER TROUGH ARE
REFLECTED IN UPPER AIR SOUNDING THIS MORNING. 850 MB TEMPS ACROSS
THE ANCHORAGE BOWL AND NORTH GULF WERE -5C TO -6C AND -11C TO -13C
OVER SOUTHWEST ALASKA/EASTERN BERING SEA. AS A RESULT MOST SHOWER
ACTIVITY HAS BEEN IN THE FORM OF SNOW WILL SOME MIXED TYPES OVER
THE GULF AND COASTS. COLD ADVECTION ACROSS THE EASTERN BERING SEA
PRODUCED STRONG NORTHERLY FROM THE CENTRAL ALEUTIANS TO OVER
BRISTOL BAY. COLD AIR SQUEEZING THROUGH THE ALEUTIAN RANGE
PRODUCED GALE FORCE WESTERLY GAP FLOWS OVER THE WESTERN GULF.

&&

.MODEL DISCUSSION (THROUGH MONDAY...
MODELS ARE ALL PAINTING THE SAME BASIC PICTURE OVER THE NEXT
COUPLE OF DAYS. ALL HAVE SIMILAR TIMING OF THE UPPER WAVE MOVING
SOUTH ACROSS THE EASTERN BERING TONIGHT...UPPER WAVE MOVING NORTH
ACROSS SOUTHCENTRAL SUN NIGHT...AND THE DEVELOPING SURFACE LOW
MOVING SOUTH OF THE CHAIN SUN/MON.

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

A WEAKENING LOW OVER THE NORTHERN GULF WILL CONTINUE TO PROVIDE
SUFFICIENT MOISTURE TO SOUTHERN ALASKA THROUGH THE
WEEKEND...ALLOWING DAYTIME CONVECTIVE SHOWERS TO FORM AGAIN TODAY
WITH THE HELP OF RESIDUAL INSTABILITY OVER THE AREA AND SOME
DIURNAL HEATING. STRONGEST SHOWERS AREA EXPECTED TO FORM MAINLY
ALONG THE HIGHER MOUNTAIN RANGES...HOWEVER WEAKER INSTABILITY AND
INCREASING MID LEVEL MOISTURE WILL DIMINISH THE INTENSITY IN
COMPARISON TO YESTERDAY. THESE SHOWERS WILL REMAIN SUFFICIENT
ENOUGH TO SUPPORT A FEW VIGOROUS SNOW SHOWERS THOUGH...ESPECIALLY
OVER THE KENAI MOUNTAINS AND NEAR THE TALKEETNA MOUNTAINS. FROM
THE BARREN ISLANDS SOUTHWARD...STOUT WESTERLY FLOW WILL CONTINUE
TO BRING STRONG GUSTY WINDS OVER THE AREA THROUGH EARLY THIS
EVENING BEFORE THE LOW WEAKENS AND MOVES NORTH OVERNIGHT.

A TROUGH AXIS NEAR KODIAK ISLAND WILL LIFT NORTHWARD ACROSS THE
NORTHERN GULF COAST INTO SOUTHERN ALASKA BY TOMORROW AFTERNOON.
THIS WILL SUPPORT WIDESPREAD ACCUMULATING SNOW SHOWERS ACROSS
COASTAL LOCATIONS...ESPECIALLY FROM PRINCE WILLIAM SOUND EASTWARD.
SHOWER ACTIVITY WILL PUSH INTO INLAND AREAS AS WELL...BUT THEY
WILL BE LESS INTENSE AND LESS WIDESPREAD AS THEY MOVE INLAND.
BUILDING HIGH PRESSURE ALONG THE COAST...AS WELL AS DEEPENING
PRESSURE AROUND COOK INLET...WILL SUPPORT GUSTY EVENING AND
OVERNIGHT GAP WINDS. TURNAGAIN ARM WINDS WILL EVENTUALLY MAKE IT
INTO SOUTH AND WEST ANCHORAGE BY EARLY TOMORROW EVENING. WINDS
WILL BEGIN TO DIMINISH OVERNIGHT TOMORROW...AS THE GRADIENT OVER
THE AREA BEGINS TO LOOSEN UP.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (TONIGHT THROUGH MONDAY)...
CLOUDY SKIES WITH SNOW SHOWERS WILL REMAIN OVER THE SOUTHWEST
MAINLAND THROUGH MONDAY MORNING AS AN UPPER LEVEL LOW PROGRESSES
TO THE SOUTH AND WEAKENS. AS MOISTURE IS BEGINNING TO DIMINISH
WITH WEAK DYNAMICS ALOFT...MOST OF THESE SHOWERS WILL BE
LIGHT...WITH THE HEAVIEST ACCUMULATIONS EXPECTED OVER NORTHERN
BRISTOL BAY. BY SUNDAY EVENING...WEAK RIDGING ALOFT WILL BEGIN TO
BUILD OVER THE SOUTHWEST MAINLAND ON SUNDAY EVENING...WHICH WILL
BRING WARMING TEMPERATURES...CLEARING SKIES TO MUCH OF THE
AREA...WITH A CHANCE OF A FEW DIURNAL SHOWERS ALONG THE MOUNTAINS.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (TONIGHT THROUGH MONDAY)...
A SHORTWAVE DIVING SOUTHEAST FROM THE BERING SEA TOWARDS THE
EASTERN ALEUTIANS WILL BRING INCREASED SNOW SHOWERS AND GUSTY
NORTHWESTERLY WINDS TO THE EASTERN ALEUTIANS AND ALASKA PENINSULA
THROUGH THIS EVENING...WHICH MAY CREATE SOME LOCALIZED AREAS OF
BLOWING SNOW ALONG THE BERING SEA COAST. AFTERWARDS THE NORTHWEST
WINDS AND SNOW SHOWERS WILL DIMINISH THROUGHOUT THE DAY SUNDAY AS
WEAK RIDGING BUILDS IN HEAD OF AN APPROACHING NORTH PACIFIC LOW.
THIS LOW IS EXPECTED TO BRING GALE FORCE WINDS WITH RAIN AND SNOW
TO THE CENTRAL ALEUTIANS ON MONDAY MORNING...AND SPREAD INTO THE
EASTERN ALEUTIANS AS IT WEAKENS ON MONDAY EVENING.

&&

.LONG TERM FORECAST (MONDAY NIGHT THROUGH SATURDAY)...

THE MEAN UPPER LEVEL TROUGH/LOW POSITION WILL BE SITUATED ACROSS
THE NORTHERN AND EASTERN BERING INCLUDING THE SOUTHWESTERN
MAINLAND AND WESTERN GULF AND EXTENDING SOUTH INTO THE NORTH
PACIFIC THROUGH MID-WEEK. AS NUMEROUS WEAK DISTURBANCES ROTATE
THROUGH...A STRONGER LOW WILL MOVE ACROSS THE NORTH PACIFIC
GRAZING THE ALEUTIANS AND ALASKA PENINSULA MONDAY INTO
TUESDAY...AND THEN HELP FEED THE BASE OF THE TROUGH OVER THE
WESTERN GULF WEDNESDAY INTO THURSDAY. THE SURFACE LOW WILL WEAKEN
SIGNIFICANTLY BEFORE MOVING INLAND LATE WEDNESDAY THROUGH LATE
THURSDAY.

A FOLLOWING LOW WILL MOVE ACROSS THE WESTERN AND CENTRAL ALEUTIANS
WEDNESDAY AND THURSDAY AND THEN REACH MATURATION OVER THE EASTERN
BERING BY FRIDAY. AS THE LOW MEANDERS INLAND OVER SOUTHWEST ALASKA
NEXT WEEKEND SEVERAL DISTURBANCES WILL ROTATE INTO SOUTHERN
ALASKA AND KEEP THE WEATHER QUITE ACTIVE FOR APRIL.

THERE ARE SOME IMPORTANT ASPECTS TO NOTE WITH THIS PATTERN. THE
FIRST IS THAT THE TRACK OF LOW PRESSURE SYSTEMS WILL CONTINUE TO
KEEP COLD AIR CLOSE BY TO SOUTHERN ALASKA. THE NEXT IS THAT MODELS
SEEM TO BE IN AGREEMENT THAT THE INDIVIDUAL DISTURBANCES ROTATING
AROUND THE UPPER LOW(S) WILL BE FAIRLY STRONG AND BE ACCOMPANIED
BY ACTIVE JET STREAKS. WHAT THIS ALL MEANS IS THAT WE CAN NOT RULE
OUT THE POTENTIAL FOR A SNOW/RAIN EVENT(S) FOR SOUTHERN ALASKA IN
THE LATE-WEEK TO EARLY WEEKEND PERIOD.
