NORTHERN ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FAIRBANKS AK
510 AM ADT WED APR 2 2008

.DISCUSSION...
ALOFT...AN UPPER TROUGH ACROSS EASTERN RUSSIA AND THE CHUKCHI SEA
WILL SLOWLY DIG INTO THE EASTERN BERING SEA AND WESTERN ALASKA BY
THE WEEKEND. HE ECMWF AS WELL AS THE GFS AND GFS ENSEMBLE MEAN
ARE NOW DEVELOPING AN UPPER RIDGE ACROSS THE BEAUFORT SEA WHICH
WOULD CAUSE MUCH OF THE ENERGY ASSOCIATED WITH THE WEST COAST
TROUGH TO PUSH INTO THE GULF OF ALASKA AND EVENTUALLY DEVELOP INTO
A REX BLOCK SIMILAR TO WHAT OCCURRED DURING MUCH OF THE LATER HALF
OF MARCH.

SURFACE...AN ELONGATED 995MB LOW PRESSURE SYSTEM ALONG THE
NORTHWEST COAST WILL LIFT NNE AND SHOULD BE ABOUT 300 NM NORTH OF
BARROW BY 00Z FRI. THE NEXT LOW IS ALREADY TAKING SHAPE WEST OF
THE ALEUTIANS AND THE MODELS ARE IN REASONABLE AGREEMENT THAT THE
LOW WILL TRACK INTO THE CENTRAL BERING SEA THIS EVENING AND SHOULD
LIFT UP TO THE SEWARD PENINSULA BY THURSDAY EVENING. ANOTHER LOW
IS EXPECT TO TAKE MORE OF A SOUTHERLY ROUTE INTO THE NORTHERN GULF
BY FRI NIGHT.

WEST COAST...THERE IS CURRENTLY A BREAK IN THE ACTION IN THE WAKE OF
THE DEPARTING STORM WITH AREAS OF LOW CLOUDS AND SPOTTY SNOW
SHOWERS...BUT NO SIGNIFICANT PRECIPITATION.  AS THE NEXT STORM
BEGINS TO MOVE CLOSER SNOW WILL DEVELOP BY EVENING ACROSS THE FAR
SOUTHWEST ZONES.  AS THE STORM LIFTS THROUGH THE BERING SEA TONIGHT
SNOW IS EXPECTED TO SPREAD NORTH AND EAST AND SHOULD REACH THE
SEWARD PENINSULA BY THURSDAY.  WILL HOIST A WINTER STORM WATCH FOR
ZONE 214 STARTING AT 9 PM THIS EVENING. IT LOOKS LIKE THERE WILL
BE STRONG WARM AIR ADVECTION...PLENTY OF MOISTURE...AND GOOD
FRONTOGENETIC FORCING. A GOOD CHANCE THAT SEVERAL INCHES OF SNOW
WILL ACCUMULATE BEFORE ANY POSSIBLE CHANGEOVER TO RAIN ON
THURSDAY. IT ALSO LOOKS LIKE THERE WILL BE SOME FAIRLY STRONG WIND
TO BOOT...WHICH WILL LOWER VISIBILITIES SIGNIFICANTLY. DUE TO ALL
THE WARM WEATHER AND RAIN THIS WEEK WILL NOT ISSUE A BLIZZARD
WATCH AS BLOWING SNOW IS NOT LIKELY TO BE AS MUCH OF A CONCERN AS
A WIND DRIVEN SNOW. THE DAY SHIFT MAY NEED TO CONSIDER EXPANDING A
WINTER STORM WATCH NORTH UP TO THE SEWARD PENINSULA AS THERE WILL
LIKELY BE ENOUGH COLD AIR IN PLACE FOR THE POTENTIAL OF A
SUBSTANTIAL DUMPING OF SNOW IN THE MOUNTAINS. IT LOOKS LIKE THIS
STORM WILL HAVE MORE SNOW THAN THE LAST ONE...BUT WITH A MIX OR
CHANGEOVER TO RAIN IN SPOTS TO THE SOUTH AND EAST OF THE LOW
CENTER.

INTERIOR...RAIN AND SNOW SHOWERS WILL BE THE RULE FOR THE NEXT
COUPLE OF DAYS WIH A MOIST SOUTHWEST FLOW. SOME STEADIER
PRECIPITATION IS POSSIBLE BY THURSDAY ACROSS THE WESTERN INTERIOR
BY THURSDAY AS THE WEST COAST STORM SLIDES INTO THE EASTERN BERING
SEA. WILL KEEP THE WINTER WEATHER ADVISORY GOING WEST OF THE
DALTON HIGHWAY THROUGH NOON AS THERE IS STILL LIKELY SOME
PRECIPITATION FALLING IN THE AREA. LIKEWISE WILL KEEP THE ADVISORY
GOING IN ZONE 219 FOR ELEVATIONS ABOVE 1000 FEET AS SOME SNOW OR
MIXED SNOW AND FREEZING RAIN IS LIKELY FALLING ACROSS THE HIGHER
TERRAIN. THE WIND HAS DROPPED OFF CONSIDERABLY IN THE PASSES OF
THE WESTERN ALASKA RANGE AND HAVE CANCELLED THE WIND ADVISORY. A
BIT MORE IN THE WAY OF WIND AND GRADIENT ACROSS THE EASTERN ALASKA
RANGE WITH TEXAS CONDO GUSTING TO 50 MPH MUCH OF THE NIGHT. THE
WIND HAS RECENTLY DIMINISHED SOME...BUT A FEW GUSTS TO AROUND 50
MPH WILL BE POSSIBLE THROUGH THIS AFTERNOON.

NORTH SLOPE...CONTINUED UNSEASONABLY MILD TODAY WITH HIGHS WELL UP
INTO THE 20S IN MOST SPOTS. A LITTLE SNOW OR SNOW SHOWER ACTIVITY
WILL BE POSSIBLE TODAY INTO TONIGHT...WITH MAINLY DRY WEATHER ON
THURSDAY.
