NORTHERN ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FAIRBANKS AK
231 PM AKDT TUE JUN 19 2012

.DISCUSSION...
ELONGATED RIDGE ALOFT OVR SRN MAINLAND ALASKA WILL CONSOLIDATE TO
A 570 DM HIGH NORTH OF WATSON LAKE YT BY THU AFTERNOON...WITH
RIDGE ARCING SOUTHWESTWARD TO WEST OF KODIAK ISLAND. MEANWHILE...COLD
LOW NR 80N 165E MOVING SLOWLY EWD TO NEAR 80N 140W BY THURSDAY
AFTERNOON. FAIRLY BRISK W-SWLY FLOW ON THE BOTTOM SIDE OF THE LOW
WILL EXTEND SOUTH TO THE NORTH SLOPE. LOW ALOFT OVR SRN KAMCHATKA
WILL MOVE INTO THE SRN BERING SEA OVR THE WEEKEND. MEANWHILE...NEXT
ARCTIC LOW WILL CUT OFF WEST OF WRANGEL ISLAND THU...THENCE DRFTG
SEWD WITH BROAD LONG WAVE TROUGH ALONG ABOUT 175W DEVELOPING.

IN THE MID-RANGE...MODELS IN BROAD AGREEMENT WITH RIDGE OVER WRN
CANADA AND TROF IN THE BERING SEA. THIS WOULD RESULT IN LITTLE
OVERALL CHANGE TO THE CURRENT PATTERN EXCEPT FOR A RETURN TO MORE
SEASONABLE ELY FLOW ON THE ARCTIC COAST. THE 12Z TUE OPERATIONAL
ECMWF PUSHES RIDGE/TROF COUPLET FARTHER EAST BY MONDAY THAN MOST
OTHER GUIDANCE AND AT THIS POINT IS REGARDED AS AN UNLIKELY
OUTLIER.

NORTH SLOPE...BRISK SW WINDS...ESPECIALLY OVR WRN ZONES...WILL
CONTINUE FOR SEVERAL DAYS. SLIGHTLY COOLER AMS MOVING IN BUT TEMPS
REMAINING MOSTLY ABOVE NORMAL THRU THU...WITH MORE SUBSTANTIAL
COOLING POSSIBLE FRI...SPCLY WRN ZONES.

WEST COAST...EXTENSIVE ST/F XPCTD TO PERSIST BERING STRAIT SWD AND
AT LEAST DIURNALLY OVR THE CHUKCHI SEA. HENCE...DENSE FOG
HEADLINES FOR LATE NIGHT/MORNING FOG AGAIN TONIGHT FOR COASTAL
ZONES. GRADIENT MAY BECOME ENOUGH WLY OVERNIGHT TO ALLOW FOR FOG
TO MOVE INTO KOTZEBUE SOUND. THIS WILL HAVE TO BE MONITORED.

INTERIOR....THUNDER THIS AFTERNOON FARTHER WEST THAN XPCD AND WE
HAVE INTRODUCED ISOLATED CONVECTION AS FAR WEST AS GALENA. CONVECTION
THE NEXT COUPLE DAYS EXPECTED TO BE LARGELY CAPPED BY THE RIDGE
ALOFT...THOUGH SOME CELLS WILL BREAK THROUGH. LACK OF THERMAL TROF
AND ATTENDANT LOW LEVEL CONVERGENCE EXPECTED TO RESULT IN WHAT
CONVECTION DOES BREAK THRU TO BE MOSTLY OVR THE UPLANDS SOUTH AND
EAST OF FAIRBANKS. TEMPS WELL ABOVE NORMAL BUT NO WHERE NEAR
RECORD LEVELS.

COASTAL HAZARD POTENTIAL DAYS 3 AND 4...NONE
NONE.

&&

.FIRE WEATHER...
WARM AND MOSTLY DRY WX WILL ALLOW FOR SGFNT DRYING BUT RED FLAG
CONDITIONS NOT EXPECTED.

&&

.HYDROLOGY...
HIGH FREEZING LEVELS ACROSS THE ALASKA RANGE WILL ACCELERATE HIGH
ELEVATION SNOW AND GLACIER MELT...WITH RISES ON RIVERS DRAINING
THESE AREAS. OTHERWISE DECLINE IN WET CONVECTION WILL ALLOW FOR
FALLING LEVELS OTRW.

&&

.AFG WATCHES/WARNINGS/ADVISORIES...
SMALL CRAFT ADVISORY FOR PKZ210-PKZ220.

GALE WARNING FOR PKZ225-PKZ230.

BRISK WIND ADVISORY FOR PKZ235.
