SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
428 PM AKST SUN FEB 14 2016

.ANALYSIS AND UPPER LEVELS...

A RATHER WEAK WEATHER PATTERN PERSISTS ACROSS ALASKA AND THE
BERING. THE ONE EXCEPTION TO THIS IS A LOW PRESSURE SYSTEM THAT IS
CURRENTLY DEVELOPING SOUTH OF THE KAMCHATKA PENINSULA...WHICH
WILL HELP TO USHER IN A BRIEF PATTERN CHANGE AND LIKELY IMPACT
MAINLAND ALASKA LATER THIS WEEK. CURRENT WATER VAPOR CONFIRMS THAT
A LOW OVER THE EASTERN ALEUTIANS CONTINUES TO DIMINISH AND LINGER
WITHOUT SUFFICIENT MOISTURE OR UPPER LEVEL SUPPORT. IN
ADDITION...THE LOW PRESSURE SYSTEM LOCATED JUST TO THE NORTHEAST
OF KODIAK ISLAND IS ALSO EXPECTED TO DIMINISH OVER THE NEXT 24
HOURS AS IT MOVES INLAND TOWARDS KING SALMON. HOWEVER...ITS
ASSOCIATED UPPER LEVEL LOW IS EXPECTED TO BRING SHOWERS ACROSS
MUCH OF BRISTOL BAY TONIGHT BEFORE IT WEAKENS. NEAR
KAMCHATKA...THE UPPER JET HAS FINALLY PUSHED NORTHWARD FROM THE
PACIFIC OCEAN INTO THE BERING. IT IS POISED TO SUPPORT RAPID
DEVELOPMENT FOR THE SURFACE LOW PRESSURE SYSTEM OVER THE NEXT
SEVERAL DAYS.

&&

.MODEL DISCUSSION...

FOR THE SHORT TERM...MODELS ARE IN GENERALLY GOOD AGREEMENT WITH
THE TIMING AND INTENSITY OF THE MAIN WEATHER FEATURES TODAY...AND
THE GFS WAS FAVORED. GENERALLY ALL MODELS INDICATE THE WEAK LOW
CURRENTLY OVER THE EASTERN ALEUTIANS WILL CONTINUE TO DETERIORATE
AND DIVE SOUTH INTO THE NORTH PACIFIC. MEANWHILE...THE UPPER WAVE
SUPPORTING SHOWERS AND GUSTY WINDS ACROSS PORTIONS OF SOUTHCENTRAL
THIS MORNING WILL CONTINUE TO DRIFT WESTWARD AND SUPPORT UNSETTLED
WEATHER ACROSS THE BRISTOL BAY REGION OVERNIGHT. THE MAIN SOURCE
OF UNCERTAINTY IS IN THE LONG TERM AS A POTENT LOW PRESSURE
SYSTEM MOVES INTO THE NORTHERN BERING...AND ITS ASSOCIATED FRONT
TRAVERSES PORTIONS OF SOUTHERN ALASKA. ALTHOUGH MODELS GENERALLY
INDICATE THE DEVELOPMENT OF A TRIPLE POINT LOW OVER KODIAK
ISLAND...MODELS HAVE SHOWN POOR RUN TO RUN CONSISTENCY IN THE GULF
IN THE LONG TERM. AS A RESULT THERE IS STILL SOME UNCERTAINTY AS
TO WHERE THE STEADIEST PRECIPITATION AND GUSTY WINDS WILL OCCUR IN
THE SOUTHERN MAINLAND TOWARDS THE END OF THIS WEEK.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (DAYS 1 AND 2)...
ANOTHER UPPER LEVEL WAVE PUSHING INLAND TONIGHT WILL BRING ONE
MORE ROUND OF SHOWERS TO SOUTHCENTRAL AK THROUGH MONDAY MORNING.
THE PASSAGE OF THIS FEATURE ON MONDAY WILL THEN SIGNAL THE
BEGINNING OF A SHIFT FROM THE PERSISTENT SHOWERY ONSHORE FLOW
PATTERN TO A DRIER AND COOLER REGIME FOR THE FIRST HALF OF THE
WORK WEEK AS A NARROW UPPER LEVEL RIDGE BEGINS TO BUILD IN FROM
THE WEST. THIS WILL LEAD TO THE DEVELOPMENT OF OFFSHORE GAP WINDS
ALONG THE NORTH GULF COAST BY TUESDAY AS COLDER AIR STARTS TO
FILTER INTO THE REGION. THE OTHER FORECAST CONCERN WILL BE THE
POTENTIAL FOR FOG DEVELOPMENT ACROSS THE COOK INLET REGION
BEGINNING MONDAY NIGHT AS SUBSIDENCE BEGINS TO TAKE HOLD BENEATH
THE BUILDING RIDGE IN THE PRESENCE OF LINGERING LOW LEVEL MOISTURE
AND WEAK SURFACE FLOW.

&&

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

A WEAKENING LOW PRESSURE SYSTEM STRADDLING THE ALASKA RANGE WILL
CONTINUE TO SPREAD LIGHT RAIN AND SNOW ACROSS THE BRISTOL BAY
REGION BEFORE DISSIPATING MONDAY. PATCHY FOG WILL BE A THREAT
ACROSS THIS REGION AS WELL AS THE PRESSURE GRADIENT WEAKENS
TONIGHT AND TOMORROW MORNING. HIGH PRESSURE SETTLES IN MONDAY
NIGHT...ALLOWING FOR POTENTIALLY MORE WIDESPREAD FOG BEFORE A FAST
MOVING FRONT MOVING IN FROM THE BERING BEGINS TO OVERSPREAD THE
LOWER KUSKOKWIM DELTA COAST LATE TUESDAY AFTERNOON AND
EVENING...SPREADING INCREASINGLY STRONG SOUTHERLY WINDS AND THE
POTENTIAL FOR ACCUMULATING SNOW.

&&

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

HIGH PRESSURE CONTINUES TO SETTLE OVER THE BERING AS A WEAKENING
LOW NEAR COLD BAY CONTINUES TO FALL APART. THIS WILL QUICKLY BE
REPLACED BY A FAST MOVING GALE FORCE WARM FRONT WHICH WILL RACE
FROM THE WESTERN BERING TONIGHT AND REACH THE SOUTHWEST MAINLAND
BY LATE TUESDAY AFTERNOON. MOST PRECIP WILL FALL AS RAIN...BUT
SOME MIX MAY OCCUR FARTHER NORTH ACROSS THE PRIBILOF ISLANDS
BEFORE RAPIDLY TURNING TO RAIN. RAIN AND SNOW SHOWERS WILL FOLLOW
BEHIND THE FRONT AS COLD AIR SWEEPS IN BEHIND IT.

&&

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

THE WEAKENING OF THE NORTH AMERICA RIDGE AND TWO LOWS SWINGING
INTO THE FAR SOUTHEASTERN GULF AND EASTERN NORTH PACIFIC WILL
HELP SHIFT AN UPPER LEVEL RIDGE OVER MAINLAND ALASKA. THE RIDGE
WILL SHARPEN TUESDAY NIGHT AS A FRONT ASSOCIATED WITH A COLD UPPER
LEVEL LOW CENTERED OVER EASTERN RUSSIA REACHES THE WEST COAST OF
ALASKA AND PUSHES AGAINST IT. THE FRONT SUPPORTED BY A VERY
STRONG JET STREAM JUST SOUTH OF THE ALEUTIANS AS WELL AS A LARGE
AREA OF COLD AIR OVER THE BERING WILL PROGRESS EAST WEDNESDAY
GRADUALLY WEAKENING THE UPPER RIDGE. AS THE FRONT HITS THE UPPER
RIDGE THE ENERGY FROM THE FRONT WILL SPLIT...WITH THE JET AND A
PORTION OF COLD AIR ALOFT DIGGING SOUTH OF THE WESTERN GULF WHILE
THE NORTHERN PORTION OF THE FRONT IS SHEARED APART BY THE
NORTHWESTERLY RETURN FLOW AROUND THE LARGE UPPER LOW OVER RUSSIA.
A RESULTING DEFORMATION BAND STRETCHED ACROSS SOUTHWEST ALASKA
WEDNESDAY NIGHT AND THURSDAY WILL NEED TO BE WATCHED FOR THE
POTENTIAL TO BRING A FAIR BIT OF ACCUMULATING SNOW.

THE RIDGE ALOFT WILL STRENGTHEN AGAIN AND BECOME ESTABLISHED OVER
EASTERN INTERIOR ALASKA AND THE YUKON TERRITORY FRIDAY. GENERAL
TROUGHING WILL REMAIN STRETCHED FROM BRISTOL BAY ACROSS THE
ALASKA PENINSULA AND INTO THE SOUTHWESTERN GULF WITH SMALLER
TROUGHS FALLING APART AS THEY ROTATE FURTHER NORTH INTO THE GULF.
THE PATTERN WILL BECOME MORE AMPLIFIED OVER THE WEEKEND WITH THE
UPPER RIDGE STRENGTHENING ACROSS WESTERN CANADA AND A CLOSED
VERTICALLY STACKED LOW SETTING UP SOUTH OF KODIAK ISLAND AROUND
50N THEN TRACKING NORTH AS IT WEAKENS THROUGH MONDAY.
