NWS Juneau, AK wrote its last area forecast discussion before this gale warning went out at Feb 28, 5:18 AM AKST, 6 hours 37 minutes earlier.

SOUTHEAST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JUNEAU AK
518 AM AKST MON FEB 28 2011

.SHORT TERM...STRONG OUTFLOW WINDS CONTINUE OVER THE PANHANDLE
THIS MORNING. ELDRED ROCK HAS BEEN RECORDING WINDS UP TO 45 KT
WITH GUSTS TO 60 KT. CAPE SPENCER IS THE HIGH WIND SPOT WITH
STORM FORCE WINDS BLOWING MOST OF THE NIGHT AND GUSTS
CONSISTENTLY UP TO 80 KT. FOR THE NON-MARINE AREAS SOUTH DOUGLAS
HAS SEEN SOME GUSTS TO 55 MPH TONIGHT AND SKAGWAY HAS BEEN
GUSTING TO 50 MPH AS WELL.

 FOR TODAY AND TONIGHT THE HIGH WINDS WILL CONTINUE AS THE
PRESSURE GRADIENT BETWEEN THE HIGH IN THE YUKON AND THE LOW OVER
THE CHARLOTTE ISLANDS REMAINS STRONG. GALES AND STORM FORCE WINDS
WITH FREEZING SPRAY ARE EXPECTED TO CONTINUE IN MOST OF THE INNER
CHANNELS PARTICULARLY IN THE NORTHER PANHANDLE. THE HIGH WIND
WARNINGS FOR YAKUTAT AND JUNEAU ARE ALSO STILL UP AS OUTFLOW
WINDS ARE STILL HIGH NEAR YAKUTAT AND THE CROSS BARRIER FLOW OVER
JUNEAU IS STILL IN THE REALM OF 80 KT. ELSEWHERE, WIND ADVISORIES
ARE ALSO STILL UP FOR MOST OF THE OTHER PUBLIC ZONES. WINDS WILL
BE STARTING TO DIMINISH LATE TONIGHT.

 COLD AIR ALSO CONTINUES TO FLOW INTO THE REGION AS TEMPS REMAIN
IN THE TEENS AND SINGLE DIGITS IN MOST PLACES. SKAGWAY IS STILL
UNDER A WINTER WEATHER ADVISORY FOR THE WIND, BLOWING SNOW, AND
LOW WIND CHILLS.

 MODELS WERE IN GOOD AGREEMENT BUT DECIDED TO USE THE 6Z NAM
SINCE IT DEPICTED CURRENT SURFACE FEATURES THE BEST. MOST OF THE
CHANGES MADE IN THE FORECAST WERE FOR LOCAL EFFECTS. FORECAST
CONFIDENCE IS ABOVE AVERAGE.

.LONG TERM...STILL SOME MODEL ISSUES HANDLING THE EVOLUTION OF
UPPER RIDGE OVER THE BERING SEA...AND THE RESULTANT RELOCATION OF
THE UPPER TROF OVER THIS AREA. TAKING A MODEL MEAN SOLUTION ON
RIDGE EVOLUTION HAS IT CLOSING OFF TO AN UPPER HIGH JUST NORTH OF
BARROW BY THE WEEKEND...WHICH WOULD ALLOW UPPER TROF TO DRIFT WWD
THROUGH THAT TIME AS SHORTWAVE ENERGY DIGS ON WEST SIDE OF THE
TROF. ALSO...MODELS ARE SHOWING INCREASING INDICATIONS OF A LOW
MOVING UP FROM THE SOUTH FOR MIDWEEK...BUT DIFFER ON HOW FAR WEST
IT WILL GO. THEY AGREE LOW WILL REACH PEAK STRENGTH WELL SOUTH OF
THE AREA THEN WEAKEN RAPIDLY AS IT CONTINUES NWD. DUE TO THE
DIFFERENCES IN THE MODELS WITH THIS SYSTEM...DID NOT WANT TO JUMP
ON IT YET. HOPEFULLY 12Z RUNS WILL COME INTO LINE WITH THIS
FEATURE. ENDED UP USING THE 06Z NAM12 FROM 12Z TUE TO 12Z
WED...THEN BLENDED TO CURRENT GRIDS THRU 00Z THU...THEN LEFT
REMAINDER OF PRESSURE GRIDS AS IS. DID USE HPC FOR THE DAY
8 PRESSURE GRIDS.

 WITH HIGH REMAINING TO THE NORTH OF THE AREA AND SOME FORM OF
LOW TO THE SOUTH...WILL KEEP TIGHT PRESSURE GRADIENTS OVER THE
AREA AND THIS WILL KEEP IT WINDY OVER THE AREA. THERE MAY BE A
LULL IN THE WINDS FOR TUE NIGHT BUT IT LOOKS LIKE THEY PICK UP
AGAIN WED. AT THIS POINT HAVE ONLY EXTENDED WIND ADVYS AND
WARNINGS AS FAR OUT AS 01Z WED. DEPENDING ON HOW MUCH OF A LULL
OCCURS TUE NIGHT MAY HAVE A BRIEF BREAK IN THE ADVYS/WARNINGS
BEFORE THEY MAY BE NEEDED AGAIN STARTING WED. THE NAM DOES SHOW A
THREAT FOR A MTN WAVE INCREASING TUE AS WEAK MID-LEVEL VORT LOBE
PASSES BY AND TURNS 500 MB FLOW MORE SSE...SETTING UP A CRITICAL
LEVEL THAT IS NOT APPARENT NOW. THE CROSS BARRIER FLOW DOES
DECREASE DURING THIS TIME BUT IS STILL IN THE 40-55 KT RANGE.

 WITH SOME WEAK SHORTWAVE ENERGY LIFTING NWD INTO THE SRN AREA
TUE...MAY SEE SOME LIGHT SNOW MOVE IN THERE...BUT THE STRONG
OFFSHORE FLOW WILL MAKE IT DIFFICULT FOR MUCH PRECIP TO FALL...SO
ONLY KEEPING CHANCE POPS FOR TUE INTO TUE EVENING OVER THE FAR
SOUTH. BETTER CHANCE FOR PRECIP LATER WED INTO WED NIGHT OVER THE
SOUTH HALF OF THE AREA AS ANOTHER SHORTWAVE AND A POTENTIAL SFC
LOW MOVE IN. AFTER THIS SYSTEM MOVES OUT...THE LARGE SCALE TROF
IS FORECAST TO MOVE FURTHER WEST LATE IN THE WEEK...AND ANY
SUBSEQUENT SYSTEMS MAY HAVE A BETTER CHANCE TO GET FURTHER NORTH.
STAY TUNED ON THIS AS THIS WOULD MEAN POTENTIAL FOR SIGNIFICANT
SNOWFALL.
