SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
415 PM AKDT WED APR 22 2015

.ANALYSIS AND UPPER LEVELS...
A 150 KT SUBTROPICAL JET IS DRIVING EASTWARD SOUTH OF THE ALEUTIAN
CHAIN BRINGING A RETURN TO MORE PROGRESSIVE FLOW ALONG THE SOUTHERN
TIER OF ALASKA AND DOWN INTO THE NORTH PACIFIC. A DEEP MATURE
VERTICALLY STACKED LOW HAS STALLED NORTH OF THE JET OVER THE FAR
WESTERN BERING WHILE AN ELONGATING OCCLUDED FRONT PROGRESSES NORTH
AND EAST ACROSS THE BERING SEA AND ALEUTIANS. DOWNSTREAM A STRONGER
MORE COMPACT VERTICALLY STACKED LOW SOUTH OF KODIAK ISLAND IS
TRACKING VERY SLOWLY EASTWARD ACROSS THE SOUTHERN GULF...LEADING
TO GRADUALLY IMPROVING CONDITIONS ACROSS KODIAK ISLAND AND THE
WESTERN GULF. MOST OF THE SOUTHERN MAINLAND IS QUIET WITH SOME MID
TO HIGH CLOUDS. THERE IS ONE INTERESTING MESOSCALE BOUNDARY
SITTING OVER SOUTHWEST ALASKA FROM JUST WEST OF DILLINGHAM
NORTHWARD TO AROUND ANIAK. A COLD POOL OF AIR REMAINING FROM THE
EXITING SYSTEM OF THE PAST WEEK (NOW OVER THE NORTHERN BERING)
SITS WEST OF THIS BOUNDARY. LOW LEVEL FLOW AROUND THE GULF LOW HAS
BROUGHT WARMER MOISTER AIR TO THE AREA EAST OF THIS BOUNDARY. WITH
GENERALLY UNSTABLE CONDITIONS ACROSS SOUTHWEST ALASKA EXPECT
CONVECTION TO INITIATE ALONG AND EAST OF THIS BOUNDARY.

&&

.MODEL DISCUSSION...
MODELS REMAIN IN EXCELLENT AGREEMENT WITH LARGE SCALE FEATURES
AND FORECAST CONFIDENCE IS MOSTLY HIGH. THE PRIMARY CHALLENGE IS
THE EVOLUTION OF THE MESOSCALE BOUNDARY OVER SOUTHWEST ALASKA
WHICH WILL PRIMARILY SERVE TO FOCUS CONVECTION TODAY...BUT WILL
THEN INTERACT WITH THE APPROACHING OCCLUDED FRONT THURSDAY MORNING
HELPING TO ENHANCE QPF OVER A NARROW CORRIDOR. THE HI-RES QPF
GUIDANCE IS ACTUALLY SURPRISINGLY CLOSE AND WILL BE USED HEAVILY.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (DAYS 1 AND 2)...
BENIGN AND PLEASANT CONDITIONS WILL PREVAIL ACROSS SOUTHCENTRAL
AK THROUGH THE END OF THE WORK WEEK AS THE DEPARTING LOW OVER THE
SOUTHERN GULF USHERS IN A CLEARING AND DRYING TREND WITH NEAR TO
SLIGHTLY ABOVE NORMAL TEMPERATURES AND GENERALLY LIGHT WINDS.
A WEAK FRONT ASSOCIATED WITH A BERING SEA LOW WILL BEGIN TO MOVE
OVER KODIAK ISLAND LATE TONIGHT AND KEEP RAIN OVER THE WESTERN
GULF THROUGH FRIDAY. ANY IMPACTS FROM THIS FRONT OVER THE MAINLAND
WILL GENERALLY BE LIMITED TO INCREASING MID/HIGH LEVEL CLOUDS ON
FRIDAY...WITH A FEW SHOWERS POSSIBLY CLIPPING THE SOUTHERN TIP OF
THE KENAI PENINSULA THURSDAY NIGHT INTO FRIDAY.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (DAYS 1 AND 2)...
SHOWERS ALONG THE MESOSCALE BOUNDARY SITTING OVER SOUTHWEST ALASKA
(AS DISCUSSED IN THE ANALYSIS AND MODEL SECTIONS) WILL DISSIPATE
THIS EVENING WITHE LOSS OF SURFACE HEATING...BUT WILL QUICKLY BE
REINVIGORATED LATER TONIGHT THROUGH THURSDAY MORNING AS THE BERING
TROUGH AND OCCLUDED FRONT NEAR. WITH THE ARRIVAL OF MORE STABLE
AIR EXPECT THIS MAY TURN INTO MORE OF A STRATIFORM BAND OF PRECIP.
PRECIP-TYPE WILL BE A MIX OF RAIN AND SNOW...WITH RAIN FAVORED
DURING THE DAY AND SNOW AT NIGHT. THE OCCLUDED FRONT WILL BE
RAPIDLY WEAKENING AS IT REACHES THE SOUTHWEST COAST EARLY THURSDAY
AND WILL COMPLETELY FALL APART BEFORE IT MAKES MUCH PROGRESS
INLAND. THUS...THE HEAVIEST PRECIP AND STRONGEST WINDS WILL OCCUR
ALONG THE COAST WITH MORE SHOWERY AND LIGHTER PRECIP AS YOU HEAD
INLAND. A WINTER WEATHER ADVISORY FOR BLOWING SNOW REMAINS IN
EFFECT FOR THE KUSKOKWIM DELTA COAST OVERNIGHT TONIGHT INTO
THURSDAY MORNING. THE WORST CONDITIONS WILL LIKELY BE AS SNOW AND
WINDS FIRST ARRIVE...WHEN TEMPERATURES ARE COLDEST AND WITH SOME
FRESH SNOW COVER FROM THE PAST FEW DAYS SITTING ON THE GROUND.
WITH PERSISTENT SOUTHERLY FLOW TEMPERATURES WILL THEN WARM TO
NEAR FREEZING AND LIMIT THE AMOUNT OF BLOWING SNOW. SHOWERS WILL
PERSIST ACROSS THE REGION THROUGH FRIDAY AS THE LOW CENTER ARRIVES
IN THE EASTERN BERING.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (DAYS 1 AND 2)...
PROGRESSIVE FLOW WILL RESULT IN FAIRLY FAST CHANGING WEATHER OVER
THE NEXT COUPLE DAYS. PRECIP BEHIND THE OCCLUDED FRONT WILL
CHANGE TO ALL RAIN. AS THE LOW CENTER PROGRESSES SLOWLY EASTWARD
ACROSS THE SOUTHERN BERING SEA TONIGHT THROUGH FRIDAY ARCTIC AIR
WILL DIVE BACK SOUTHWARD ON THE BACK SIDE OF THE LOW. THIS WILL
CAUSE GUSTY NORTHWESTERLIES TO DEVELOP AND CAUSE A CHANGE IN
PRECIP-TYPE BACK TO SNOW. A RIDGE OF HIGH PRESSURE WILL QUICKLY
BUILD INTO THE WESTERN BERING LATE FRIDAY QUICKLY BRINGING AN END
TO THE WINDS AND SNOW SHOWERS.

&&

.LONG TERM FORECAST (DAYS 3 THROUGH 7)...
THE MAIN FEATURE IN THE MIDTERM IS THE EAST BERING LOW. THERE IS
GOOD AGREEMENT AMONG THE GUIDANCE THAT THE LOW WILL TRACK TO THE
SOUTHERN GULF SATURDAY. HOWEVER...THERE ARE SOME MINOR
DISCREPANCIES IN WHEN THE LOW CONSOLIDATES AS THEY ALL HAVE IT
BECOMING A DOUBLE BARREL LOW FRIDAY NIGHT AS IT TRACKS TOWARDS THE
GULF. THE GFS IS A LITTLE SLOWER THAN THE OTHERS CONSOLIDATING
THE LOW BUT THE OVERALL PLACEMENT AND IMPACTS ARE IN GOOD
AGREEMENT LEADING TO ABOVE AVERAGE CONFIDENCE. THE MAJORITY OF THE
PRECIP WILL BE FOR KODIAK WITH THE REST OF THE SOUTHCENTRAL UNDER
DECENT WEATHER. THE LOW WILL THEN SLOWLY WEAKEN THROUGH EARLY
NEXT WEEK.

OUT WEST RIDGING WILL FOLLOW THE EAST BERING LOW BRINGING NICER
CONDITIONS TO THE SOUTHWEST LATE IN THE WEEKEND THROUGH EARLY NEXT
WEEK. THERE IS DISCREPANCY BETWEEN THE MODELS AS TO WHAT HAPPENS
NEXT. FOR THE MOST PART THEY ARE BRINGING A LOW OR TROUGH THROUGH
THE BERING FROM THE WEST. BUT CONSISTENCY BETWEEN THE MODELS WAS
NOT GREAT WITH THE 12Z RUNS LEADING TO LOWER CONFIDENCE WITH HOW
THIS SYSTEM WILL TRACK INTO NEXT WEEK.
