SHORT TERM
RAIN AND WIND ARE THE STORY OF THE DAY FOR THE
REMAINDER OF THURSDAY, AS A FRONT PUSHES INTO SE AK. ELEVATED AND
GUSTY WINDS ARE SPREADING FROM NW TO SE AS OF THE TIME OF WRITING,
AND THE WIND AND RAIN LOOK SET TO CONTINUE THROUGH THURSDAY
NIGHT, BEFORE DEPARTING ON FRIDAY, LEAVING ONSHORE FLOW AND
SHOWERS IN ITS WAKE. ANTICIPATE THAT MORE INTERIOR AREAS LIKE
JUNEAU, PETERSBURG, AND WRANGELL, WILL HAVE THE BEST CHANCES OF
SHOWERS.
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.
