NORTH ALASKA FORECAST DISCUSSION
230 PM AST FRI FEB 6 2004

.DISCUSSION...A BREAK IN TH ACTIVE WEATHER PATTERN THAT HAS BEEN
AFFECTING NORTHERN ALASKA IS EXPECTED TO BEGIN THIS EVENING, THEN
LAST THROUGH SAT BEFORE ANOTHER STRONG LOW CENTER BEGINS TO AFFECT
OUR WEATHER ON SUN AS IT MOVES NE-WARD OVER SOUTHWEST ALASKA. THE
STRONG WINDS AND LOW WIND CHILLS THAT HAVE BEEN AFFECTING PLACES
ALONG THE WEST COAST ARE SLOWLY DIMINISHING THIS AFTERNOON AS THE
LOW CENTER THAT GENERATED THE WINDS WEAKENS OVER SOUTH-CENTRAL
ALASKA. THE SNOW THAT HAS BEEN FALLING OVER THE EASTERN 2/3 OF THE
INTERIOR AND ARCTIC ZONES IS BEGINNING TO DIMINISH FROM SOUTH TO
NORTH AND THE LOW CENTER WEAKENS AND MOVES INTO CANADA. SOME
CLEARING IS LIKELY FROM FAIRBANKS WEST AND NORTH TONIGHT AND SAT.
HOWEVER, ANOTHER, WEAKER LOW CENTER WILL LIKELY BRING MORE CLOUDS
AND LIGHT SNOW TO THE EXTREME SOUTHEAST INTERIOR ON SAT AS IT
MOVES INTO EXTREME SOUTHEAST MAINLAND ALASKA. THE WEST COAST WILL
SEE MOSTLY CLOUDY SKIES AND RATHER COLD TEMPS THROUGH AT LEAST SUN
AS HIGH PRESSURE RIDGING REMAINS IN CONTROL AT THE SURFACE.

LIGHT N-LY FLOW SHOULD KEEP THE WESTERN ARCTIC COAST MOSTLY CLOUDY
AND COLD WITH FLURRIES AND FOG AT TIMES THROUGH SAT. STRONG W-LY
WINDS AND LOW WIND CHILLS ARE EXPECTED TO CONTINUE ALONG THE
EASTERN ARCTIC COAST TONIGHT THEN DIMINISH ON SAT AS THE LOW
PRESSURE TROUGH GENERATING THE WINDS WEAKENS AND MOVES NE-WARD
AWAY FROM THE REGION. SURFACE WINDS ARE EXPECTED TO BECOME E-LY
ALONG THE ARCTIC COAST ON SUN WITH SOME CLEARING AS A HIGH CENTER
MOVES E-WARD TO THE NORTH.

CLOUDS AND WINDS ARE EXPECTED TO INCREASE OVER ALL OF NORTHERN
ALASKA SUN AND SUN NIGHT AS A DEEP LOW CENTER MOVES OVER SOUTHWEST
ALASKA. LIGHT SNOW IS LIKELY TO FALL OVER MOST AREAS SOUTH OF THE
BROOKS RANGE WITH THE HEAVIEST SNOWS FALLING OVER THE NORTHERN
INTERIOR, AWAY FROM THE DRYING EFFECTS OF THE ALASKA RANGE. QUITE
STRONG N-LY WINDS ARE LIKELY TO DEVELOP OVER MANY AREAS OF THE
WEST COAST WITH LOW WIND CHILLS AGAIN EXPECTED FROM THE SEWARD
PENINSULA N-WARD. TEMPS OVER THE EASTERN INTERIOR WILL LIKELY INTO
THE TEENS AND 20S ABOVE ZERO BY MON. AFTER A BRIEF BREAK ON TUE,
YET ANOTHER LOW CENTER SHOULD BRING MOE CLOUDS, WINDS, AND SNOW TO
OUR FORECAST AREA ON WED AND THU.
