NATIONAL WEATHER SERVICE JUNEAU AK
815 PM AKST TUE FEB 17 2026
SYNOPSIS
KEY MESSAGES:
- STRONG NORTH AND NORTHEAST WINDS CONTINUE SLIGHTLY DIMINISHING
THROUGHOUT THE DAY TUESDAY. WINDS WILL RELAX LATE TUESDAY INTO
WEDNESDAY.
- TEMPERATURES CONTINUE TO TREND DOWN THROUGH THE WEEK.
SHORT TERM
/ THROUGH WEDNESDAY NIGHT / COLD DRY OUTFLOW
CONTINUES FROM TONIGHT THROUGH WEDNESDAY. THE BIGGEST THING IS THAT
THE OUTFLOW PATTERN IS WEAKENING OVERNIGHT AND INTO WEDNESDAY SO THE
WINDS IN THE LYNN CANAL REGION IS LOWERING FROM 30 MPH TONIGHT TO 15
MPH BY WEDNESDAY AFTERNOON. THE RESULTING WIND GUSTS DIMINISHING AS
WELL. THE LATER HALF OF WEDNESDAY WILL HAVE COOLER AIR TEMPERATURES
ACROSS THE SOUTHEAST PANHANDLE. THIS WILL HELP SET UP THE AREA FOR
SOME LIGHT SNOW STARTING TO PUSH IN FROM THE WEST OVER THE NORTHERN
GULF OF ALASKA. THE SNOW WILL START TO MOVE TO THE NE GULF COAST AND
NORTHERN COASTAL AREA LATE WEDNESDAY NIGHT.
LONG TERM
WEDNESDAY NIGHT THE AXIS OF A RIDGE ALOFT WILL
CONTINUE TRANSITING EAST INTO B.C, WITH THE STOUT PRESSURE
GRADIENT WHICH WAS RESPONSIBLE FOR OUR STRONG OUTFLOW WEAKENING,
LEAVING MUCH LIGHTER WINDS FOR THE INNER CHANNELS. WESTERLY FLOW
UPSTREAM OF THE RIDGE AXIS WILL BEGIN TO TRANSPORT SOME MOISTURE
INTO THE PANHANDLE EARLY THURSDAY, HELPING DRIVE SOME SNOW
THURSDAY INTO FRIDAY. CURRENT FORECAST SHOWS THE BEST SNOW
POTENTIAL ALONG THE NORTHERN COAST AND IN THE CENTRAL AND SOUTHERN
PANHANDLE, WITH A RANGE OF 3 TO 7 INCHES POSSIBLE; 2 INCHES OR
LESS FOR JUNEAU NORTH. FRIDAY THE LONGWAVE TROUGH BEGINS TO DIG
SOUTH, FORMING INTO A CLOSED LOW ALONG THE WESTERN SEABOARD OVER
THE WEEKEND. AS THIS FEATURE TRANSITS SOUTH, A VERY TIGHT SURFACE
PRESSURE GRADIENT FORMS AGAIN BETWEEN AN ARCTIC HIGH IN CANADA AND
THE RELATIVE WARM WATERS OF THE GULF, INCREASING THE CONFIDENCE
THAT STRONG GALE FORCE OUTFLOW WINDS RETURN FOR MANY INNER CHANNELS
THROUGH THE WEEKEND WITH THE ASSOCIATED COLDER WEATHER AND FREEZING
SPRAY.
INTO EARLY NEXT WEEK, OUTFLOW DIMINISHES AGAIN AS THE YUKON HIGH
WEAKENS AND A NEW WEATHER SYSTEM MOVES IN FROM THE W. THE
POSSIBILITY OF PRECIPITATION RETURNS FOR MOST AREAS BY TUESDAY WITH
MOST OF THE AREAS LIKELY STILL COLD ENOUGH FOR IT TO BE MOSTLY SNOW.
AVIATION.../THROUGH 00Z THURSDAY/
WIDESPREAD VFR CONDITIONS
CONTINUE WITH CLEAR SKIES AND PERFECT VIS. WINDS HAVE DECREASED
FOR HALF OF THE PANHANDLE, WHILE SOME SITES ARE STILL ATTEMPTING
TO HOLD ON TO 20 TO 30 KT GUSTS. HAINES AND GUSTAVUS ARE STILL
EXPERIENCING ISOLATED GUSTS UP TO 20 KTS, THOUGH THESE ARE
EXPECTED TO DIMINISH THROUGH THE EVENING. SKAGWAY, JUNEAU, AND
WRANGELL ARE EXPECTED TO HOLD ONTO THEIR GUSTS FOR LONGER, WITH
JUNEAU DROPPING OFF OVERNIGHT, WRANGELL STAYING AROUND 20 KTS
THROUGH THE NIGHT, AND SKAGWAY STAYING AROUND 30 KTS AND STARTING
TO INCREASE AGAIN TOWARDS THE END OF THE PERIOD. TOWARD THE END OF
THE PERIOD, SUSTAINED WINDS IN HAINES MAY INCREASE AGAIN WITH THE
INCREASE OF GUSTS IN SKAGWAY. LLWS, MAINLY SPEED SHEAR, AT AROUND
1000 FT IS STILL HANGING AROUND NEAR TYPICAL OUTFLOW EXITS, SUCH
AS TAKU INLET OR THE MOUTH OF THE STIKINE. AS SUCH, LLWS IN JUNEAU
IS MAINLY IMPACTING GASTINEAU CHANNEL. THIS IS EXPECTED TO
DIMINISH AS WINDS CALM DOWN, SO LLWS MAY PERSIST LONGER FOR
WRANGELL.
MARINE
OUTSIDE: OFFSHORE FLOW FROM THE CHANNELS DIMINISHES THROUGH TUESDAY
NIGHT. SEAS ARE ON THEIR WAY DOWN, WITH RESIDUAL NW SEAS, MASKING SW
SWELL GENERATED FROM A SYSTEM A FEW DAYS AGO SOUTH OF THE ALEUTIANS.
SIGNIFICANT HEIGHTS LESS THAN 12FT BY TUESDAY EVENING, AND BETWEEN 5-
9 FEET ON WEDNESDAY, WITH THE HIGHEST SEAS OVER THE OPEN GULF.
INSIDE: TUESDAY DAWNS WITH GALE FORCE WINDS HOWLING ACROSS THE
NORTHERN AND CENTRAL INNER CHANNELS, ALONG WITH USUAL OUTFLOW AREAS.
THE CURRENT FORECAST MAINTAINS SUSTAINED WINDS OF STRONG GALE FORCE
IN LYNN CANAL, WITH WIDESPREAD GALES ALONG AND NORTH OF SUMNER
STRAIT THROUGH TUESDAY EVENING. THESE WINDS WILL GENERATE FREEZING
SPRAY, WITH MODERATE TO HEAVY FREEZING SPRAY FOR PRIME AREAS LIKE
NORTHERN LYNN AND TAKU INLET. EXPECT WINDS TO SLOWLY DIMINISHING
TUESDAY NIGHT INTO WEDNESDAY, WITH MODERATE TO FRESH BREEZES
EXPECTED WEDNESDAY AFTERNOON THROUGH FRIDAY MORNING. HOWEVER, FRIDAY
EVENING WINDS ARE EXPECTED TO RAMP BACK UP TO GALE FORCE FOR MOST
CENTRAL/NORTHERN CHANNELS WITH THE THREAT OF HEAVY FREEZING SPRAY
BECOMING MORE EXTENSIVE.
