Area forecast discussion, Dec 5, 5:07 AM AKST, 10 hours 30 minutes before
SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
507 AM AKST SAT DEC 5 2015
.ANALYSIS AND UPPER LEVELS...
THE MAIN NORTH PACIFIC JET STREAM CONTINUES TO REMAIN SOUTH OF THE
REGION...KEEPING THE ALASKA REGION OUT OF THE ACTIVE STORM TRACK.
A STRONG AND VERY LARGE LOW EXISTS ACROSS THE NORTHEAST PACIFIC
JUST SOUTH OF THE GULF OF ALASKA...WITH AN ELONGATED TROUGH SOUTH
OF THE KAMCHATKA PENINSULA EXTENDING EASTWARD TO JUST SOUTH OF THE
WESTERN ALEUTIAN ISLANDS. OVER THE WESTERN BERING SEA...THERE IS
A WEAK AND BROAD UPPER LEVEL TROUGH AXIS...WITH A WEAK SHORTWAVE
RIDGE BUILDING INTO THE EASTERN BERING SEA. OVER SOUTHCENTRAL...A
SERIES OF WEAK UPPER SHORTWAVE TROUGHS ARE MOVING NORTHEAST ACROSS
SOUTHCENTRAL...AND WILL REACH THE CANADIAN BORDER BY LATE THIS
MORNING. WITH THE WEAKENING OCCLUDED FRONT ASSOCIATED WITH THE
STRONG NORTHEAST PACIFIC LOW MOVING INTO THE GULF TODAY THROUGH
TONIGHT...AND INCREASING PRESSURE BUILDING ACROSS SOUTHERN
ALASKA...OFFSHORE FLOW WILL INCREASE HEADING THROUGH THE WEEKEND.
OUT WEST...THE NORTH PACIFIC JET STREAM WILL STRENGTHEN TO AN
IMPRESSIVE 190 KTS AND MOVE EAST...WITH WAVINESS ALONG THE JET
RESULTING IN A SERIES OF LOWS TRACKING INTO THE NORTH CENTRAL
PACIFIC AND EVENTUALLY INTO THE GULF OF ALASKA BY TUESDAY.
&&
.MODEL DISCUSSION...
THE MODELS ARE IN EXCELLENT AGREEMENT WITH THE LARGE SCALE
HEMISPHERIC PATTERN INTO NEXT WEEKEND...AND ARE IN GOOD AGREEMENT
WITH THE GENERAL IMPACTS REGION WIDE INTO NEXT WEEK...BUT THEY
BEGIN TO DIVERGE WITH THE DEVELOPING DEEP LOW MOVING INTO THE GULF
OF ALASKA LATE MONDAY EVENING INTO TUESDAY. THEY ALSO DIVERGE
RATHER QUICKLY ACROSS THE BERING WITH RESPECT TO NUMEROUS SMALL
MESOSCALE LOWS WRAPPING AROUND/ALONG THE FRONT INTO THE BERING SEA
SUNDAY AND MONDAY. HOWEVER...THESE IMPACTS ARE MUCH LOWER AND
OVERALL DO NOT IMPACT THE FORECAST ALL THAT MUCH. THE ECMWF AND
GFS TENDED TO AGREE WITH THE OVERALL PRESSURE PATTERN AND UPPER
LEVEL PATTERN THE BEST...SO THEY WERE FAVORED FOR BOTH THE SHORT
TERM AND EXTENDED...ALTHOUGH SOME NAM WAS FAVORED ACROSS
SOUTHCENTRAL TO BETTER HANDLE OFFSHORE GAP WINDS HEADING THROUGH
THE WEEKEND. FOR THE DEEP LOW LATE MONDAY INTO TUESDAY...A TREND
TOWARD THE GFS AND ECMWF WAS FAVORED...BUT LARGE UNCERTAINTY STILL
CLOUDS THE DEVELOPMENT OF THAT LOW...ALTHOUGH THERE IS NOW
MODERATE TO HIGH CONFIDENCE THAT THE LOW WILL EXIST SOMEWHERE IN
THE GULF...JUST LOW CONFIDENCE ON TRACK. NONETHELESS...THAT LOW
WILL LARGELY BE A MARINE IMPACT...WITH A CONTINUED OFFSHORE
PRESSURE GRADIENT KEEPING INLAND LOCATIONS LARGELY DRY THROUGH
TUESDAY BEFORE THE REMNANTS OF THE LOW MOVE INLAND.
&&
.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (DAYS 1 AND 2)...
THE LAST OF A SERIES OF UPPER SHORT-WAVES IS EXITING TO THE NORTH
TODAY. WITH THE LOSS OF MID AND UPPER LEVEL MOISTURE AND DEVELOPMENT
OF SURFACE-BASED TEMPERATURE INVERSIONS...AREAS OF STRATUS AND FOG
HAVE FORMED. A RECENT SUOMI-VIIRS NIGHTTIME MICROPHYSICS RGB
SATELLITE IMAGE SHOWS A WELL DEFINED AREA AREA OF STRATUS/FOG FROM
THE WESTERN KENAI WITH A NARROW STRIP BANKED UP AGAINST THE CHUGACH
MOUNTAINS FROM ANCHORAGE TO EKLUTNA. THERE LIKELY ARE OTHER AREAS
ACROSS INTERIOR SOUTHCENTRAL...BUT MID LEVEL CLOUDS ARE BLOCKING
THE VIEW. THE LOW SUN ANGLE THIS TIME OF YEAR USUALLY MEANS THIS
STUFF WILL HANG AROUND FOR A WHILE. HOWEVER...EXPECT INCREASING
NORTHERLY WINDS LATER TODAY THROUGH TONIGHT IN RESPONSE TO A WARM
FRONT MOVING UP FROM THE PACIFIC AND TRACKING WESTWARD ACROSS THE
GULF TO KODIAK ISLAND. THUS...GENERALLY EXPECT DIMINISHING CLOUDS
ACROSS SOUTHCENTRAL AND AT LEAST PARTIAL EROSION OF FOG/STRATUS
WITH THE INCREASE IN VERTICAL MIXING.
HIGH PRESSURE WILL BUILD OVER SOUTHCENTRAL THROUGH THE REMAINDER
OF THE WEEKEND INTO EARLY NEXT WEEK...WITH A CUT-OFF HIGH SETTING
UP DIRECTLY OVERHEAD. WITH MOSTLY CLEAR SKIES THIS WILL BE IDEAL
CONDITIONS FOR SIGNIFICANT COOLING OF THE AIR MASS. EXPECT COOLING
TEMPERATURES REGION-WIDE...WITH THE COLDEST TEMPERATURES IN THE
COPPER RIVER BASIN.
CONTINUED ACTIVITY ACROSS THE GULF OF ALASKA AND NORTHEAST PACIFIC
COMBINED WITH COOLING OVER INTERIOR SOUTHCENTRAL WILL LEAD TO
TIGHTENING PRESSURE GRADIENTS AND DEVELOPMENT OF GAP WINDS ALONG
PRINCE WILLIAM SOUND AND THE NORTH GULF COAST. THERE WILL NOT BE
MUCH IN THE WAY OF UPPER LEVEL SUPPORT TO ADVECT THE COLDER AIR
OFFSHORE. THEREFORE...GENERALLY EXPECT THIS TO BE A WEAK EVENT
WITH THE STRONGEST WINDS THROUGH THE GAPS AND IN THE IMMEDIATE
EXIT OF THE GAPS...BUT NOT MUCH FARTHER. WITH THE COLDEST AIR
SETTING UP IN THE COPPER RIVER BASIN...THE VALDEZ TO THOMPSON
PASS AREA CAN EXPECT SOME OF THE STRONGEST GAP WINDS.
&&
.SHORT TERM FORECAST SOUTHWEST ALASKA (DAYS 1 AND 2)...
THE SOUTHWEST WILL CONTINUE WITH DRY CONDITIONS WITH AN UPPER
LEVEL RIDGE POSITIONED OVER THE REGION. COOLER TEMPERATURES WILL
FILTER IN FROM THE NORTH AND COINCIDE WITH OFFSHORE FLOW THROUGH
SATURDAY. BY SUNDAY A FRONTAL BOUNDARY WILL BE POSITIONED IN THE
BRISTOL BAY REGION WITH INCREASED CLOUD COVER PRODUCING WARMER
TEMPERATURES ALONG THE SOUTHWEST COASTLINES. THE COLDEST TEMPERATURES
WILL BE FARTHER INLAND THROUGH THE LOWER KUSKOKWIM VALLEY AND THE
KUSKOKWIM DELTA.
&&
.SHORT TERM FORECAST BERING SEA/ALEUTIANS (DAYS 1 AND 2)...
THE BROAD COMPLEX LOW PRESSURE SYSTEM REMAINS SOUTH OF THE WESTERN
TO CENTRAL ALEUTIAN CHAIN THIS MORNING. THE STRONG 175 KNOT
NORTHWESTERLY ZONAL JET STREAM LOCATED IN THE NORTH PACIFIC
CONTINUES TO DIG INTO THE BASE OF THE LONGWAVE TROUGH BEFORE
TRANSITIONING TO ZONAL FLOW SOUTH OF THE CENTRAL ALEUTIANS. THIS
WILL KEEP STORMS SOUTH OF THE CHAIN THROUGH THE WEEKEND.
OTHERWISE...THE BERING IS PREDOMINANTLY NORTHEASTERLY FLOW AND
LOOK FOR THE WINDS TO INCREASE TO GALE FORCE OVER THE WESTERN
BERING BY LATE TONIGHT. BY SUNDAY NIGHT THERE WILL BE INCREASED
PRESSURE GRADIENT OVER THE WESTERN BERING SEA AND THE GALE FORCE
WINDS WILL INCREASE TO STORM FORCE WINDS. THE BERING AND THE
ALEUTIANS WILL BE UNDER A SHOWERY WEATHER REGIME THROUGH THE
WEEKEND.
&&
.LONG TERM FORECAST (DAYS 3 THROUGH 7...MON THROUGH
FRI)...
A BROAD LONG WAVE PATTERN CENTERS NEAR THE EASTERN ALEUTIANS FOR
THE EXTENDED FORECAST ON MONDAY...SHIFTING SLOWLY EAST THROUGH THE
WEEK. THE MOST ACTIVE WEATHER AT THE BEGINNING OF THE WEEK WILL BE
FOCUSED AROUND THE LOW CENTER THAT DEVELOPS IN THE EASTERN PACIFIC
ON MONDAY. A STRONG STORM SYSTEM IS EXPECTED TO QUICKLY SPIN UP
FROM THIS SYSTEM AND MOVE INTO THE SOUTHERN GULF MONDAY NIGHT.
MODELS CONTINUE TO STRUGGLE WITH THE STRENGTH AND TRACK OF THIS
SYSTEM...THEREFORE ONLY MINOR EDITS WERE MADE TO INCREASE WINDS
AND PRECIPITATION CHANCES USING INFLUENCE FROM THE ECMWF WHICH HAD
THE BEST RUN TO RUN CONSISTENCY. THE 06Z GFS IS STARTING TO ALIGN
BETTER WITH THE ECMWF AND BOTH ARE BRINGING A SURFACE LOW BETWEEN
950-955MB INTO THE EASTERN GULF EARLY TUESDAY MORNING. THIS STORM
IS CURRENTLY EXPECTED TO TRACK INTO THE NORTHEASTERN GULF ON
WEDNESDAY MORNING...THEN WEAKEN AS IT MOVES TOWARD THE KENAI.
ANOTHER STRONG WAVE ENTERS THE WESTERN BERING EARLY WEDNESDAY AND
IS PROJECTED TO MERGE WITH A PACIFIC WAVE WHICH ESSENTIALLY
AMPLIFIES THE LONG WAVE AND SETS A NEW PATTERN INTO MOTION.
