Area forecast discussion, Aug 5, 4:07 PM AKDT, 10 hours 5 minutes before

NORTHERN ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FAIRBANKS AK
407 PM AKDT SUN AUG 5 2012

.SYNOPSIS...
ALOFT...
VERY DEEP LOW OVER HIGH ARCTIC NORTH OF ALASKA WILL EXPAND SOUTH
OVER ALASKA THROUGH MID-WEEK AND THEN RIDGING WILL BUILD BACK OVER
ALASKA THE SECOND HALF OF THE WEEK. THIS MEANS RAPID WEST FLOW
WILL DEVELOP OVER THE NORTHERN HALF OF ALASKA NOW THROUGH TUE
BRINGING IN RAIN AND WEST SURFACE WINDS ACCOMPANYING A WEATHER
FRONT ALONG WITH COOLER TEMPERATURES. CONDITIONS WILL BECOME
WARMER AND MORE DRY THE SECOND HALF OF THE WEEK.

AT THE SURFACE...
A 970 MB LOW 600 NM NORTHWEST OF BARROW WILL MOVE NORTH. A STRONG
WEATHER FRONT STRETCHING SOUTH FROM THIS LOW ACROSS THE EASTERN
CHUKCHI SEA WILL MOVE TO LIE FROM DEMARCATION POINT TO THE BERING
STRAIT BY 4PM MON AND THEN MOVING TO ARCTIC VILLAGE TO THE YUKON
DELTA BY 4PM TUE. THERE ARE SW WINDS 30 MPH JUST AHEAD OF THE FRONT
NOW BLOWING FROM THE BERING STRAIT TO BARROW. THERE ARE GUSTS OF
40 TO 50 MPH AS WELL. WINDS WILL TURN WEST 25 MPH JUST BEHIND THE
FRONT AND THEN DROP OFF TO 15 MPH AFTER THE FRONT. THIS IS CAUSING
SEAS TO 10 FT WELL OFF SHORE OVER THE CHUKCHI SEA NOW BUT NEAR
SHORE WAVES ARE MUCH LESS DUE TO THE OFFSHORE COMPONENT. WAVES
NEAR SHORE ALONG THE CHUKCHI COAST WILL INCREASE TONIGHT TO 4 FT
AS WINDS TURN WEST BUT SURF IS EXPECTED TO ONLY BE AT MODERATE
LEVELS DUE TO THE WINDS DECREASING POST FRONT. WINDS ALONG THE
FRONT WILL BE WEAKER AS THE FRONT MOVES EAST.

EXPECT .25 TO .50 INCH OF RAIN ALONG THE FRONT AS THE FRONT MOVES
SE ACROSS THE STATE.

&&

.DISCUSSION...
MODELS INITIALIZE WELL AND SHOW SIMILAR SOLLUTIONS THROUGH 4AM TUE.
AFTER THAT TIME THE NAM MOVES THE SURFACE FRONT SOUTH FASTER THAN
THE GFS. PREFER THE GFS SOLUTION FOR TUE.

COASTAL HAZARD POTENTIAL DAYS 3 AND 4...NONE

&&

.FIRE WEATHER...
CONDITIONS WILL WARM AND DRY A BIT IN THE EASTERN INTERIOR MON BUT
THE FRONT WILL BRING A WETTING RAIN IN FROM THE WEST TUE. COULD
SEE A FEW LIGHTING STRIKES IN ZONE 224 THIS EVENING.

&&

.HYDROLOGY...
NOTHING SIGNIFICANT AT THIS TIME.

&&

.AFG WATCHES/WARNINGS/ADVISORIES...
