SOUTHEAST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JUNEAU AK
552 AM AKDT FRI OCT 3 2025
SHORT TERM
THE ONCE NEAR-GALE FORCE FRONT CONTINUES TO FALL
APART AND BECOME DISCONNECTED FROM THE PARENT LOW AS IT PUSHES
THROUGH THE PANHANDLE FRIDAY MORNING. WINDS IN THE INNER CHANNELS
WILL LARGELY CONTINUE TO DIMINISH THROUGH THE MORNING HOURS AND
DRIER CONDITIONS WILL GRADUALLY MOVE IN THROUGH THE DAY BEHIND
THE FRONT. A RIDGE BUILDING IN THE GULF THROUGH THE DAY FRIDAY AND
INTO THE WEEKEND WILL CONTINUE TO BRING ONSHORE FLOW HOWEVER,
WITH SOME SHOWERS POSSIBLE ALONG THE INNER CHANNELS FROM RESIDUAL
LOW LEVEL MOISTURE IN THE WAKE OF THE RECENT FRONT. OTHERWISE
RELATIVELY BENIGN WEATHER ON THE HORIZON WITH TEMPERATURES RANGING
FROM THE LOW 40S TO UPPER 50S.
LONG TERM
SATURDAY SEES A BREAK FOR THE PANHANDLE IN TERMS OF
PRECIPITATION AND LIGHTER WINDS FROM A RELAXED GRADIENT. THE ONE
EXCEPTION BEING LYNN CANAL, WHICH, MOSTLY DRIVEN BY LEESIDE
TROUGHING FROM WESTERLY WIND ALOFT MOVING OVER THE COAST MOUNTAINS
AND TROUGHING IN THE INTERIOR OF CANADA, CAN SEE WINDS UP TO A
MODERATE BREEZE IN THE AFTERNOON HOURS.
SUNDAY HAS SOME INCREASED CONFIDENCE, WITH ENSEMBLE GUIDANCE
COMING INTO SOME ALIGNMENT REGARDING TIMING OF HEAVIER RAINFALL
FOR YAKUTAT. CLUSTER ANALYSIS, MAINLY FOCUSED AROUND THE EPS AND
GEPS WITH SOME MINOR INFLUENCE BY THE GEFS, HAS YIELDED A SOLUTION
LEANING WETTER FOR YAKUTAT, WITH MORE UNCERTAIN RAIN FOR THE REST
OF THE PANHANDLE. IN AROUND A 48 HOUR PERIOD, CURRENTLY EXPECTING
2.5 - 4.0 INCHES OF RAINFALL WITH AROUND A 20% CHANCE TO EXCEED 5
INCHES IN THE SAME DURATION. MODELS DIVERGE SIGNIFICANTLY AFTER
THIS POINT, WITH SOME INDICATING THAT HEAVIER RAINFALL WILL MOVE
OVER THE PANHANDLE AND OTHERS KEEPING IT NEAR THE NE GULF COAST.
ULTIMATELY, THERE IS GOOD AGREEMENT THAT THE PRECIPITATION LOOKS
TO COME TO AN END FOR A SHORT BREAK BY WEDNESDAY.
SHORT NOTE ABOUT SNOW BECAUSE IT IS THAT TIME OF YEAR: NOT
EXPECTING MUCH OF THE HAINES OR KLONDIKE HIGHWAY DURING THE LONG
TERM FORECAST. THE UPCOMING RAIN MAKER FOR YAKUTAT LOOKS TO BRING
IN HEFTY WARM AIR ADVECTION OVER THE AREA, PUSHING SNOW LEVELS
WELL ABOVE 5000 FT.
