NORTHERN ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FAIRBANKS AK
113 AM AKDT TUE JUN 8 2010

.DISCUSSION...
UPPER RIDGE WITH AXIS FROM ST LAWRENCE ISLAND TO NORTH OF
BARTER ISLAND WILL REMAIN STATIONARY THROUGH WED WITH
HEIGHTS FALLING 2-3 DECAMETERS. BEYOND WEDNESDAY THE
00Z GFS RUN CONTINUES TO BE MORE AGGRESSIVE ON LOWERING
HEIGHTS THAN ITS ENSEMBLE MEAN OR THE 00Z EUROPEAN RUN.
FOR THU...PREFER THE EUROPEAN/NAM AND ENSEMBLE MEAN
WITH LITTLE CHANGE IN 500 MB HEIGHTS FROM WED...BUT
WITH A GENERAL SOUTHEAST FLOW DEVELOPING OVER THE SOUTHERN
INTERIOR AREAS.

06Z SURFACE ANALYSIS SHOWS THE SURFACE THERMAL TROUGH
EXTENDING IN AN ARC FROM SOUTHWESTERN ZONE 215 TO
NORTH OF FAIRBANKS THEN SOUTHEAST TO THE EAGLE/CHICKEN
AREAS AND ON INTO THE YUKON TERRITORY. MOST OF MONDAYS
THUNDERSTORM ACTIVITY OCCURRED ALONG AND NEAR THIS
TROUGH...WITH A SECONDARY MAXIMUM ALONG THE BROOKS RANGE
AND INTERIOR ARCTIC SLOPE. LITTLE CHANGE IN THE STRENGTH
AND LOCATION OF THE THERMAL TROUGH IS EXPECTED TODAY.
ON WEDNESDAY THE TROUGH LINE IS EXPECTED TO EXTEND
FROM ZONE 217 TO NORTH OF FAIRBANKS THEN SOUTHEASTWARD
TO THE CHICKEN AREA AND THEN INTO THE YUKON TERRITORY. FOR
THU...A BROAD AREA OF THERMAL LOW PRESSURE IS EXPECTED OVER THE
INTERIOR WITH WEAK LOW CENTER OVER ZONE 216 AND EXTREME
NORTHEASTERN ZONE 220.

THUNDERSTORM FORECAST FOR TODAY...ISOLATED THUNDERSTORMS
OVER MOST INTERIOR AREAS EXCEPT IN ZONE 220-EASTERN ZONE 218.
THE MOST ACTIVE AREA WILL BE ALONG AND NEAR THE THERMAL TROUGH.
ADDITIONALLY...EXPECT SOME ISOLATED ACTIVITY OVER MOST OF THE
BROOKS RANGE AND CENTRAL/WESTERN PARTS OF THE INTERIOR ARCTIC
SLOPE.

THUNDERSTORM FORECAST FOR WED...LITTLE CHANGE FROM TODAY...
BUT A FEW STORMS MAY BE POSSIBLE OVER THE SOUTHERN UPLANDS
IN THE UPPER YUKON VALLEY.

CONVECTIVE OUTLOOK FOR THU...ISOLATED THUNDERSTORMS OVER
MOST OF THE BROOKS RANGE/INTERIOR ARCTIC SLOPE AND INTERIOR
ZONES EXCEPT ZONES 223-225-226.

ON THE ARCTIC COAST...MAINLY CLEAR OR PARTLY CLOUDY SKIES
EXPECTED UNDER THE UPPER RIDGE WITH GENERALLY LIGHT WINDS
THROUGH WED. PATCHY RADIATIONAL FOG MAY BE POSSIBLE LATE
NIGHT AND EARLY MORNING HOURS BUT IT SHOULD BE BRIEF IN
DURATION.

GOES VIS SHOWING LOW STRATUS OVER ALL OF OUTER KOTZEBUE
SOUND AND ADJACENT COAST AND PARTS OF INNER KOTZEBUE SOUND. NO
CHANGE EXPECTED AT TODAY AND TONIGHT WITH WEST TO SOUTHWEST WIND
FLOW CONTINUING. THERE IS ALSO EXTENSIVE STRATUS OVER ZONE 213 AND
PARTS OF WESTERN NORTON SOUND. MAINLY WEST TO NORTH SURFACE WINDS
ALONG THE NORTHERN SEWARD PENINSULA COAST SHOULD KEEP THE STRATUS
OFFSHORE.

EXTENDED OUTLOOK...00Z GFS RUN LOOKS WAY TOO AGGRESSIVE IN
BRINGING MUCH LOWER 500 MB HEIGHTS INTO MUCH OF THE INTERIOR.
THE MORE MODERATE SOLUTIONS FROM THE EUROPEAN RUN AND GFS
ENSEMBLE MEAN ARE PREFERRED...RETAINING SOME UPPER RIDGING
AND HIGHER 500 MB HEIGHTS THAN THE GFS. THIS SHOULD KEEP INTERIOR
TEMPERATURES NEAR OR AT WORST ONLY SLIGHTLY BELOW SEASONAL
NORMALS.

COASTAL HAZARD POTENTIAL DAYS 3 AND 4...NONE

&&

.FIRE WEATHER...
RED FLAG WIND GUSTS ARE NOT EXPECTED IN THE INTERIOR THROUGH
WED...GENERAL WINDS WILL LIKELY BE 10 MPH OR LESS IN MOST
AREAS...LOCAL GUSTS TO 15 MPH IN THE AFTERNOON AND EARLY EVENING
POSSIBLE IN SOME AREAS. SEVERAL STATIONS IN THE NORTHEAST INTERIOR
REPORTED MIN RH NEAR 15 PERCENT MON...AND VERY DRY CONDITIONS ARE
EXPECTED AGAIN TODAY AND WED IN ZONE 220...RED FLAG MAY BE NEEDED
FOR LOW RH. FIRE IN THIS AREA ARE LIKELY TO BECOME VERY ACTIVE IN
THE AFTERNOON AND EVENING...ACTIVE SMOKE PLUMING FROM SEVERAL
FIRES IN ZONE 220 NEAR THE ALCAN BORDER WAS SEEN ON MONDAY
AFTERNOON/EVENING GOES VIS LOOP.

&&

.HYDROLOGY...
NO RIVER PROBLEMS EXPECTED.

&&

.AFG WATCHES/WARNINGS/ADVISORIES...
NONE.
