NWS Juneau, AK wrote its last area forecast discussion before this gale warning went out at Mar 2, 5:49 AM AKST, 4 hours 18 minutes earlier.

SOUTHEAST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JUNEAU AK
549 AM AKST WED MAR 2 2011

.SHORT TERM...HIGH PRESSURE WILL REMAIN OVER THE YUKON THROUGH
TONIGHT. A STRONG LOW JUST SW OF VANCOUVER ISLAND WILL WEAKEN AND
 MOVE N TO DIXON ENTRANCE BY LATE THIS EVENING. USED THE 06Z
NAM12 FOR THE FORECAST THROUGH TONIGHT AS IT HAD A GOOD HANDLE ON
THE MAIN FEATURES...AND WANTED TO KEEP THE SMALLER SCALE EFFECTS
THAT IT SHOWS BETTER THAN THE OTHER MAIN MODELS.

 MAIN FORECAST CONCERN WILL BE WINDS. PRESSURE GRADIENT WILL
TIGHTEN TODAY AS THE LOW TO THE S MOVES CLOSER. ALSO...A
MID-LEVEL TROF WILL MOVE N OF THE PAJN AREA BY LATE THIS
MORNING...AND THIS WILL SET UP PRIME TAKU WIND CONDITIONS AS
500 MB FLOW TURNS SLY AFTER TROF MOVES BY. WILL KEEP THE HIGH
WIND WARNING GOING LOCALLY AND EXPECT GUSTS UP TO 90 MPH IN THE
TAKU WIND AREA FROM LATE THIS MORNING THROUGH AT LEAST LATE THIS
EVENING. ALSO...OUTFLOWS REMAIN STRONG AND WILL ONLY INCREASE AS
THE GRADIENT TIGHTENS...SO WILL KEEP THE REMAINING WIND ADVYS AND
THE WARNING FOR PAYA NEAR INTERIOR PASSES GOING THROUGH THE SHORT
TERM PERIOD. PAGY ZONE WILL HAVE BOTH WIND AND WIND CHILLS AT
ADVY LEVELS THROUGH TONIGHT SO WILL KEEP WINTER WX ADVY GOING
THERE.

 OTHER ISSUE WILL BE PRECIP POTENTIAL. SYSTEM WILL HAVE A
WEAKENING OCCLUDED FRONT MOVE NWD INTO THE SRN AREA BY EARLY THIS
EVENING AND IT SHOULD GO ALOFT SHORTLY THEREAFTER. WILL SET UP AN
OVERRUNNING SCENARIO OVER THE FAR SRN AREA AS FLOW JUST ABOVE
LOWER LEVELS BECOMES SLY...SO DO EXPECT PRECIP TO FALL WITH THE
FRONT BEGINNING THIS AFTERNOON OVER THE FAR SRN AREA...THEN
DIMINISH FOR A SHORT PERIOD LATE THIS EVENING AS MID-LEVEL DRY
SLOT MOVES IN. OVERNIGHT THOUGH WEAKENING SECOND WRAP OF FRONT
WILL MOVE INTO THE SRN AREA...AND THIS SHOULD BRING MORE PRECIP
BACK IN. WITH THE LOWER LEVELS STILL VERY DRY...AND NE LOW LEVEL
FLOW EXPECTED TO PERSIST AHEAD OF THE FRONT...NOT EXPECTING LARGE
PRECIP AMTS. BUT 1-3 INCHES OF SNOW IS LIKELY FOR THE FAR SRN
AREA THROUGH TONIGHT. MOS GUIDANCE WANTED TO GO WITH LARGER
AMOUNTS...UP TO 8 INCHES...BUT BELIEVE WITH SYSTEM WEAKENING SO
MUCH THAT THE DEEP LAYER LIFT WILL NOT BE STRONG ENOUGH TO
WARRANT THAT MUCH SNOW.

 OTHERWISE...CLOUDS WILL INCREASE FROM THE S TODAY INTO THIS
EVENING...AND THE COLD TEMPS WILL MODERATE SOME ESPECIALLY OVER
THE S. BUT TEMPS WILL STILL REMAIN WELL BELOW AVERAGE FOR EARLY
MARCH.

&&

.LONG TERM...EXTENDED RANGE FORECAST BEGINS WITH ONE LOW WEAKENING
AND HEADING BACK OUT TO SEA AS ANOTHER ONE WELL SOUTH OF THE GULF
TRACKS RAPIDLY FIRST TO THE NORTHEAST TOWARD A LOCATION WEST OF
THE QUEEN CHARLOTTES...AND THEN NORTH OVER THE FAR EASTERN GULF.
NET EFFECT OF THIS WILL BE A BRIEF RELAXATION OF THE STRONG
NORTHEASTERLY PRESSURE GRADIENT AND ASSOCIATED OUTFLOW WINDS. AM
NOT...HOWEVER...EXPECTING ANY DRAMATIC WARM UP. TEMPERATURES WILL
BE SEVERAL DEGREES WARMER BOTH DAY AND NIGHT...BUT STILL WELL
BELOW NORMAL FOR THIS TIME OF YEAR SINCE THERE WILL BE NO
MECHANISM IN PLACE TO DISPLACE THE VERY COLD NEAR SURFACE AIRMASS.

ASSOCIATED WITH THE NEXT LOW WHICH WILL ARRIVE IN THE SOUTHEASTERN
GULF ON FRIDAY MORNING...A WEAK FRONT WILL TRACK NORTH OVER THE
SOUTHERN HALF OF THE PANHANDLE. THE FRONT IS NOT WELL ORGANIZED IN
MODEL DATA ALTHOUGH THERE IS A SIGNIFICANT AMOUNT OF MID LEVEL
ENERGY TO WORK WITH. BELIEVE OUTFLOW WINDS WILL HAMPER AREAL
EXTENT OF THE PRECIP FIELD AND LIKELY HINDER PRECIP RATES AS A
RESULT OF DOWN SLOPE DRYING. HAVE THEREFORE LIMITED LIKELY POPS TO
THE AREA SOUTH OF AND INCLUDING FREDERICK SOUND. FOR POINTS
SOUTH...AM EXPECTING UP TO 3 INCHES IN SOME LOCATIONS BETWEEN
WEDNESDAY NIGHT AND THURSDAY NIGHT.

USED NAM FOR UPDATES THURSDAY THROUGH FRIDAY NIGHT. FORECAST
CONFIDENCE IS AVERAGE.
