SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
1230 PM AKDT TUE APR 17 2012

.ANALYSIS AND UPPER LEVELS...A LARGE UPPER LEVEL CLOSED LOW REMAINS
NEARLY STATIONARY SOUTH OF THE ALASKA PENINSULA. RAIN AND LOW
CLOUDS ARE FOCUSED NEAR THE LOW CENTER FROM KODIAK ISLAND TO THE
ALASKA PENINSULA. WATER VAPOR IMAGERY SHOWS A WELL DEFINED SHORT-WAVE

EXTENDING FROM THE CENTRAL GULF TO SOUTHEAST ALASKA ROTATING
NORTHWESTWARD TOWARD SOUTHCENTRAL. RADAR SHOWS RAINFALL IS CURRENTLY
CONFINED TO THE GULF AND IMMEDIATE COASTAL AREAS. HOWEVER EXPECT RAIN
TO HEAD FARTHER INLAND THIS AFTERNOON AND EVENING AS THE SHORT-WAVE
ARRIVES. ALTHOUGH INLAND AREAS ARE DRY THE LOW AND SHORT-WAVE ARE
PRODUCING EXTENSIVE CLOUD COVER ACROSS THE SOUTHERN MAINLAND OF
ALASKA. THIS HAS RESULTED IN WARMER NIGHT-TIME TEMPERATURES...BUT
ALSO COOLER DAY-TIME HIGHS. CLOUDS ARE ALSO THE RULE OUT OVER THE
WESTERN BERING WHERE AN UPPER RIDGE HAS BEEN PARKED THE PAST FEW
DAYS.

A MODERATE STRENGTH LOW OVER THE NORTHEAST PACIFIC IS TRACKING
NORTHWARD TOWARD THE GULF BUT WILL LOSE STRENGTH AS IT MOVES AWAY
FROM THE UPPER JET. MEANWHILE A STRONG SHORT-WAVE OVER FAR EASTERN
RUSSIA IS DROPPING SOUTHWARD INTO THE NORTHERN BERING.

.MODEL DISCUSSION...MODELS HAVE COME INTO DECENT AGREEMENT WITH LOW
OVER NORTHEAST PACIFIC AS IT MOVES INTO THE SOUTHERN GULF WEDNESDAY.
THERE HAS BEEN A TREND TOWARD A WEAKER SYSTEM WITH A MORE SOUTHERLY
TRACK...WHICH MEANS LESS PRECIP WILL MAKE IT TO SOUTHCENTRAL.
SOLUTIONS DIVERGE A BIT WITH HANDLING OF NEXT LOW MOVING INTO THE
EASTERN GULF THURSDAY NIGHT AND FRIDAY. THERE HAS BEEN A CONSISTENT
TREND TOWARD A MORE WESTWARD TRACK. THEREFORE...WILL TREND TOWARD
THE GFS SOLUTION WHICH WILL BRING STRONGER WINDS INTO THE CENTRAL
GULF.

.SHORT TERM FORECAST...

SOUTHERN MAINLAND/GULF...PRINCE WILLIAM SOUND AND THE KENAI PENINSULA
WILL RECEIVE THE BRUNT OF RAIN AS SHORT-WAVE CURRENTLY OVER THE GULF
MOVES OVERHEAD TONIGHT. INLAND AREAS WILL ALSO SEE LOWERING CLOUDS
AND A CHANCE OF SHOWERS. THE SHORT-WAVE WILL WEAKEN AS IT TRACKS
TO SOUTHWEST ALASKA TUESDAY...BUT EXPECT ENOUGH LIFT TO GENERATE
SCATTERED SHOWERS ACROSS THE REGION. THE LOW THAT HAS BEEN STATIONARY
SOUTH OF KODIAK ISLAND AND THE ALASKA PENINSULA WILL FINALLY HEAD
SOUTHWARD AND DISSIPATE TUESDAY NIGHT AND WEDNESDAY...BUT THE LOW
OVER THE NORTHEAST PACIFIC WILL TRACK WESTWARD AND SETTLE IN THE
SAME AREA ON THURSDAY. FLOW ACROSS SOUTHCENTRAL WILL BACK TOWARD
THE NORTH AHEAD OF THIS SYSTEM WHICH WILL KEEP THE BULK OF PRECIP
OVER THE GULF. THE CHANGE IN FLOW WILL LEAD TO SOME SUNSHINE FROM
INTERIOR SOUTHCENTRAL TO SOUTHWEST ALASKA ON THURSDAY. MODEL
STABILITY PARAMETERS ARE UNIMPRESSIVE SO DON'T THINK WE'LL BE QUITE
WARM ENOUGH TO PRODUCE DIURNAL CONVECTION. THE FORECAST FOR THE
SOUTHERN MAINLAND ON FRIDAY BECOMES MUCH LESS CLEAR. MORE CHAOTIC
FLOW ALOFT WILL RESULT IN A SERIES OF SHORT-WAVES IN THE AREA WHICH
HAVE THE POTENTIAL TO PRODUCE CONVECTION. ANOTHER STORM WILL MOVE
INTO THE EASTERN GULF FRIDAY BUT LIKELY STALL IN THAT AREA AS WE
TRANSITION TOWARD A MORE PROGRESSIVE UPPER LEVEL PATTERN.

BERING SEA/ALEUTIANS...THE SHORT-WAVE OVER EASTERN RUSSIA WILL DROP
RAPIDLY SOUTHWARD ACROSS THE CENTRAL BERING AND ALEUTIANS TONIGHT
AND WEDNESDAY. OMEGA AND POTENTIAL VORTICITY FIELDS INDICATE STRONG
DOWNWARD MOTION WITH THIS TROUGH WHICH MEANS STRONGER WINDS WILL MIX
DOWN TOWARD THE SURFACE. WEAK COLD AIR ADVECTION AND A TIGHTENING
SURFACE PRESSURE GRADIENT WILL ALSO CONTRIBUTE TO STRONGER WINDS.
THE PATTERN WILL CHANGE BEHIND THIS SHORT-WAVE AS THE TROUGH SOUTH
OF KODIAK RE-CENTERS FURTHER EAST...THE WESTERN BERING RIDGE MOVES
TO THE NORTH CENTRAL PACIFIC...A TROUGH DROPS DOWN OUT OF RUSSIA
WHILE ANOTHER MOVES INTO THE NORTHWEST PACIFIC. THIS WILL RESULT
IN MORE ACTIVE WEATHER OUT WEST WITH THE FIRST STORM EXPECTED TO
ARRIVE ALONG THE ALEUTIANS BY LATE THIS WEEK.

.LONG TERM FORECAST...THE UPPER LEVEL FLOW WILL BECOME MUCH MORE
PROGRESSIVE NEXT WEEKEND. MEDIUM RANGE MODELS ARE IN GOOD AGREEMENT
IN TRACKING STORM SYSTEM ALONG THE ALEUTIANS OVER THE WEEKEND AND
TO MAINLAND ALASKA BY EARLY NEXT WEEK.

.AER/ALU...WATCH/WARNING SUMMARY
PUBLIC...NONE.
MARINE...NONE.
FIRE WEATHER...NONE.
