NORTHERN ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FAIRBANKS AK
547 AM ADT WED JUN 4 2008

.SYNOPSIS...
A LONG WAVE TROUGH EXTENDING FROM THE EASTERN BERING INTO THE GULF
OF ALASKA WILL PERSIST THROUGH THU THEN PROGRESS EAST OVER
MAINLAND ALASKA FRI AS A STRONG SHORT WAVE MOVES EAST INTO THE
GULF OF ALASKA PULLING THE WHOLE TROUGH EAST. THIS MEANS THE
CURRENT WEAKLY UNSTABLE AIRMASS WILL PERSIST OVER THE INTERIOR
THROUGH FRI ALONG WITH SEASONABLE TEMPERATURES.

AT THE SURFACE...AN ARCTIC FRONT FROM WAINWRIGHT TO THE BERING
STRAIT TO A LOW DEVELOPING IN THE WESTERN BERING WILL MOVE TO
WAINWRIGHT TO THE BERING STRAIT TO A 985 MB LOW JUST EAST OF ST
MATTHEW ISLAND BY 4PM WED...TO POINT HOPE TO THE BERING STRAIT TO
A 989 MB LOW NEAR NUNIVAK ISLAND BY 4AM THU..AND TO POINT HOPE TO
THE BERING STRAIT TO THE LOW NEAR KING SALMON BY 4PM THU. WILL SEE
RAIN AND SNOW ALONG THE FRONT TURNING TO SNOW WEST OF THE FRONT.
WILL ALSO SEE NORTH WINDS 15-25 KT ALONG AND WEST OF THE FRONT
WITH NORTHERLY GALE FORCE WINDS IN THE NORTHWEST QUADRANT OF THE
SURFACE LOW.

THE AIRMASS OVER MOST OF THE INTERIOR AND BROOKS RANGE WILL REMAIN
WEAKLY UNSTABLE THROUGH FRI WITH NEGATIVE LIS AND CAPES OF 200 JOULES.
THIS WILL ALLOW ISOLATED AFTERNOON AND EVENING THUNDERSTORMS IN
THESE AREAS THROUGH FRI CENTERED AROUND SEVERAL FOCUSING TROUGHS.

A THERMAL LOW PRESSURE TROUGH FROM BETHEL TO ANAKTUVUK PASS TO
ARCTIC VILLAGE WILL MOVE ALONG THE ARCTIC COAST BY 3PM WED AND
THEN WEAKEN. WILL SEE ISOLATED SHOWERS ALONG THIS TROUGH.

A SHORT WAVE TROUGH ALOFT FROM DENALI TO FORT YUKON WILL MOVE TO
AMBLER TO ARCTIC VILLAGE BY 4PM WED AND TO BARROW TO OLD CROW BY 4AM THU
AND THEN WEAKENING. THE IS AN AREA OF WIDESPREAD SHOWERS NOW OVER
ZONES 221 AHEAD OF THIS TROUGH WILL MOVE NORTHWEST AHEAD OF THIS
TROUGH TODAY. EXPECT .25 TO .50 INCH OF RAIN WITH THIS. THERE WILL
A SHARP CLEARING LINE SOUTH OF THIS TROUGH WHICH IS CAUSING PATCHY
FOG THIS MORNING. WILL SEE ISOLATED THUNDERSTORMS BEHIND THE
TROUGH THIS AFTERNOON AS THE MOISTENED LOW LEVEL AIR HEATS UP.

A SECOND TROUGH ALONG THE GULF OF ALASKA COAST WILL MOVE TO THE
EASTERN ALASKA RANGE BY 4PM WED...TO DENALI TO EAGLE BY 4AM THU...
TO MCGRATH TO FAIRBANKS TO EAGLE BY 4PM THU...AND TO ANVIK TO
TANANA TO OLD CROW BY 4PM FRI. THIS WILL BE ANOTHER FOCUSING
MECHANISM WITH SCATTERED SHOWERS AHEAD OF THIS AND ISOLATED
THUNDERSTORMS TO THE SOUTH.

&&

.DISCUSSION...
MODELS INITIALIZE WELL AND SHOW SIMILAR PATTERNS THROUGH FRI.
THE MAIN DIFFERENCE IS THE STRENGTH OF THE LOW ALOFT DEVELOPING
OVER THE BERING WED AND THU WITH THE GFS 500 MB LOW 40M DEEPER
THAN THE NAM OVER THE ALASKA PENINSULA BY 4PM THU. AT 850 MB THE
NAM COOLS THE SOUTHERN INTERIOR MORE ON THU THAN THE NAM.

COASTAL HAZARD POTENTIAL DAYS 3 AND 4...NONE

&&

THEY WILL REMAIN ABOVE 30%.
