NWS Juneau, AK wrote its last area forecast discussion before this gale warning went out at Jan 8, 2:29 PM AKST, 13 hours 31 minutes earlier.

SOUTHEAST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JUNEAU AK
229 PM AKST SAT JAN 8 2011

.SHORT TERM...STRONG BLOCKING UPPER LEVEL HIGH CONTINUES TO
BUILD AND MOVE NORTH OVER NORTHWEST ALASKA. A WEAK UPPER LEVEL
TROUGH WILL DROP SOUTH ACROSS SOUTHEAST ALASKA TONIGHT. THE FIRST
IN A SERIES OF ARCTIC SURFACE HIGHS CONTINUES TO BUILD OVER THE
YUKON AND NORTHERN BC AND SHOULD PEAK AT ABOUT 1055 MB SUNDAY. AN
INVERTED TROUGH OF LOW PRESSURE EXTENDING FROM VANCOUVER ISLAND
NNW THROUGH OUR COASTAL WATERS WILL ALSO PERSIST. SHALLOW ARCTIC
AIR UNDER A STRONG INVERSION WILL CONTINUE THROUGH SUNDAY.

 MAIN ISSUE THROUGH THE SHORT TERM WILL BE WINDS AND
TEMPERATURES. CURRENTLY HAVE A MODERATELY STRONG NORTHERLY GAP
FLOW EVENT UNDERWAY. EXPECT GALES IN LYNN CANAL AND OUT OF
INTERIOR PASSES TO CONTINUE AND PROBABLY STRENGTHEN A BIT THROUGH
SUNDAY BUT STRONG STABILITY HAS LIMITED WINDS OVER LAND. AS WEAK
UPPER TROUGH DROPS SOUTH TONIGHT SHOULD SEE ENOUGH MIXING IN
SKAGWAY AREA TO BREAK INVERSION AND DELIVER ADVISORY LEVEL GUSTS
BY LATE EVENING WHICH THEN CONTINUES. DO NOT HAVE A CRITICAL
LEVEL IN JUNEAU AREA SO DO NOT EXPECT TAKU WIND BUT WILL ALSO SEE
A SLIGHT INCREASE IN WINDS AS WEAK UPPER TROUGH PASSES TONIGHT.
STIKINE RIVER AND PORTLAND CANAL WILL ALSO BE ACTIVE GAPS ON THE
INSIDE WITH GAPS ALONG NE GULF COAST. ELSEWHERE NORTH WINDS IN
SMCR RANGE. DID NOT INCLUDE FREEZING SPRAY IN SHORT TERM AS BUOY
TEMPS STILL ABOVE FREEZING BUT WILL BE TRENDING THAT WAY BY
SUNDAY AFTERNOON.

 THE SHALLOW DEPTH OF ARCTIC AIR IS PREVENTING A WIDESPREAD RAPID
COOLING ACROSS THE AREA. INSTEAD COLD AIR WILL BE GENERATED FROM
BOTTOM UP WITH LOW TEMPS AROUND 5 DEGREES COLDER TONIGHT AND
STAYING AT OR BELOW FREEZING TOMORROW.

 SKIES WILL BE MAINLY CLEAR WITH JUST A FEW HIGH AND MID CLOUDS
PASSING THROUGH LATE TONIGHT. EXPECT SOME MIFG TO FORM LATE THIS
AFTERNOON AND EARLY EVENING BUT THIS WILL FROST OUT QUICKLY.
SOUTH CENTRAL AND SOUTHERN COULD ALSO SEE A FEW FOG PATCHES
THROUGH THE NIGHT.

 MODELS IN VERY GOOD AGREEMENT AND CONSISTENT. DID REWORK WINDS
USING NAM12 FOR GUIDANCE AND TEMPS USING GFS ADJUSTED TO
OBSERVATIONS AND A BIT OF PERSISTENCE.

.LONG TERM...MODELS IN GOOD AGREEMENT ON THE LARGE SCALE PATTERN
THRU THE WEEK. DOMINANT FEATURE WILL BE THE ANOMALOUS UPPER HIGH
OVER NW AK...WHILE SEVERAL SHORTWAVES MOVE SWD THRU SE AK DURING
THE WEEK. THE SHORTWAVES WILL ONLY HAVE SOME MID AND HIGH LEVEL
CLOUDS AT MOST...BUT THEY WILL EACH USHER IN A COLDER AIRMASS
THAN THE ONE BEFORE IT. THE WEEK WILL START OUT WITH TEMPS ONLY
SLIGHTLY BELOW NORMAL...BUT BY THE END OF THE WEEK THEY WILL BE
MUCH BELOW NORMAL...POSSIBLY BY 20 DEGREES OR SO. AFTER COORD WITH
WFO PAFC...ENDED UP USING THE 12Z NAM FROM 00Z MON TO 00Z
TUE...INCREASING BLEND OF 12Z EC FROM 06Z TUE TO 00Z WED...THEN
LATEST HPC FOR THE REMAINDER OF THE PERIOD. WANTED TO USE HPC
LATER ON AS MODEL TIMING AND INTENSITY OF SHORTWAVES FOR LATE WEEK
DIFFER SOMEWHAT...ALONG WITH HOW INTENSE THE ARCTIC AIRMASS WILL
GET BY WEEKS END.

FIRST SHORTWAVE SHOULD MOVE SWD THRU THE AREA SUN NIGHT. WITH MAIN
VORT TRACKING JUST SE OF THE AREA...NOT EXPECTING MUCH MORE THAN
SOME HIGH CLOUDS WITH THIS FEATURE. IT WILL START THE COOLING
TREND THOUGH WITH MON HIGH TEMPS A FEW DEGREES LOWER THAN SUN.

NEXT SHORTWAVE WILL BE DROPPING SWD THRU THE AREA TUE. THE MAIN
VORT WILL TRACK FURTHER WEST THAN PREVIOUS SHORTWAVE SO MAY SEE
MORE CLOUDS FROM IT...BUT THEY WILL LIKELY BE ON THE THIN SIDE
STILL SO KEEPING MOSTLY CLEAR TO PARTLY CLOUDY FOR TUE. MAX AND
MIN TEMPS WILL LOWER SEVERAL MORE DEGREES ESPECIALLY FOR TUE
NIGHT INTO WED. A COUPLE MORE SHORTWAVES WILL MOVE SSW THRU THE
AREA FOR LATE WEEK INTO THE WEEKEND...USHERING IN THE COLDEST
AIRMASS IN A WHILE FOR THE AREA DURING THAT TIME.

DURING THE ENTIRE WEEK WINDS WILL REMAIN BLUSTERY WITH GALES LIKELY
OVER THE MORE N-S CHANNELS ESPECIALLY N AREA...AND SCA AT TIMES
FOR THE MORE E-W CHANNELS. WILL NOT CHANGE THE END TIME OF THE
PAGY WIND ADVY ATTM BUT IT WILL LIKELY NEED EXTENDING LATER
ON...ALTHOUGH THERE MAY BE LULLS IN THE STRONGER WINDS JUST AHEAD
OF EACH SHORTWAVE AS THEY WEAKEN THE HIGH OVER NW CANADA FOR A
SHORT TIME. MOST LIKELY PERIOD FOR A SIGNIFICANT DROP IN WINDS
WOULD BE MON NIGHT.
