Area forecast discussion, Oct 23, 10:26 AM AKDT, 3 hours 41 minutes before

NORTHERN ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FAIRBANKS AK
1026 AM AKDT TUE OCT 23 2012

.DISCUSSION...
STRONG BLOCKING HIGH OVER THE BERING SEA WILL BUILD A
LITTLE MORE THROUGH TONIGHT AND REMAIN IN PLACE THROUGH
SAT. HEIGHTS OVER THE BERING SEA AND THE NORTHERN AK
MAINLAND WILL BE MUCH ABOVE NORMAL. STRONG HIGH PRESSURE
AT THE SURFACE WILL PERSIST OVER THE BERING SEA AND
THE NORTHERN AK MAINLAND THROUGH FRI. MAINLY CLEAR SKIES
CONTINUING OVER INTERIOR AREAS...BUT THERE WILL BE SOME
AREAS OF LOW STRATUS...ALSO SOME PATCHES OF FOG LATE AT
NIGHT AND EARLY MORNING.

OVER THE HIGH ARCTIC...A SHORT WAVE TROUGH IS EXPECTED TO
TRAVEL AROUND THE NORTHERN PERIPHERY OF THE RIDGE FRI
THROUGH SAT...DIVING SE INTO THE WRN CANADA ARCHIPELAGO
SUN. AN ASSOCIATED SURFACE SYSTEM IS EXPECTED TO DEVELOP
ABOUT 500 MILES W OF WRANGEL ISLAND EARLY FRI AND TRAVEL
ACROSS THE HIGH ARCTIC ON A CURVING TRAJECTORY...ARRIVING
IN THE WRN CANADA ARCHIPELAGO SAT.

THE OUTER FRINGE OF THE CIRCULATION ASSOCIATED WITH THIS
SURFACE LOW WILL BRING STRONGER WINDS TO THE ARCTIC COAST...
BEGINNING WED EVENING FROM THE BARROW AREA WWD. STRONGER
WINDS WILL SPREAD ALONG THE REST OF THE ARCTIC COAST THU
INTO THU NIGHT. WINDS WILL BE INITIALLY S TO SW THEN SHIFT
TO W.

COASTAL HAZARD POTENTIAL...ELEVATED SURF AND A SMALL INCREASE
IN SEA LEVELS POSSIBLE ALONG THE ARCTIC COAST...BEGINNING
OVER THE WRN SECTIONS WED NIGHT AND SPREADING EWD THU INTO
THU NIGHT. THE GREATEST POTENTIAL FOR ELEVATED SURF AND SEA
LEVELS WILL BE ALONG THE COAST IN AKZ204 THU NIGHT THROUGH FRI
NIGHT WITH SUSTAINED WEST WINDS 25-30 MPH. AFTER A BRIEF
LULL...ANOTHER PERIOD OF BRISK WEST WINDS IS POSSIBLE ALONG THE
COAST FROM BARROW EWD SAT AFTERNOON THROUGH SAT NIGHT AS ANOTHER
SURFACE SYSTEM DIVES SE OUT OF THE HIGH ARCTIC INTO THE WRN CANADA
ARCHIPELAGO. THIS COULD BRING ANOTHER ROUND OF ELEVATED SURF AND
SEA LEVELS. BOTH THE GFS AND ECMWF ARE LOCKING ON TO THIS SECOND
SYSTEM BUT DIFFER SOME ON THE SPEED AND TRACK SO THERE IS SOME
UNCERTAINTY IN TIMING OF THE WINDS GENERATED BY THE SECOND SYSTEM.
