.DISCUSSION...

INTERIOR...
LIGHT SNOW HAS TAPERED OFF TO FLURRIES ACROSS THE INTERIOR THIS
MORNING AS THE LOW PRESSURE SYSTEM HAS WEAKENED AND ONLY AREAS OF
STRATUS REMAIN OVER MOST OF THE INTERIOR. THE UPPER TROUGH WILL
REMAIN OVER THE INTERIOR THIS WEEKEND. CLOUDS AND FLURRIES WILL
PERSIST INTO SUNDAY.

WEST COAST...WINDS WILL REMAIN AT OR ABOVE 15 MPH ALONG THE
BERING STRAIT COAST IN ZONE 213 AND ZONE 207 WHERE WIND CHILL
ADVISORIES ARE IN EFFECT. WIND CHILL ADVISORIES WERE EXTENDED TO
SUNDAY MORNING AS WINDS AND TEMPS ARE NOT EXPECTED TO IMPROVE IN
THESE AREAS.

NORTH SLOPE...COLD TEMPERATURES REMAIN OVER THE NORTH SLOPE. HIGH
PRESSURE OVER SIBERIA WILL CONTINUE TO INFLUENCE THE WESTERN
NORTH SLOPE. A PRESSURE GRADIENT INCREASE OVER THE EASTERN NORTH
SLOPE WILL INCREASE THE WEST WINDS THIS AFTERNOON AND PRODUCE WIND
CHILLS OF 55 BELOW INTO SUNDAY MORNING. WIND CHILL ADVISORIES HAVE
BEE ISSUED FOR ZONES 203 AND 204.

VERY LITTLE CHANGE IN THE FORECAST PHILOSOPHY DURING THE MEDIUM
RANGE.  A DEEP MEAN UPPER TROUGH EXTENDS FROM THE BEAUFORT SEA TO
THE SOUTHWEST MAINLAND AND INTO THE GULF OF AK MON NIGHT.  THE LOW
CENTER SLOWLY MIGRATES TO THE VCNTY OF THE BERING STRAIT BY
FRI...BUT WITH MUCH OF NORTHERN AK UNDER THE INFLUENCE OF THE COLD
LOW ALOFT.  TEMPS WILL CONTINUE TO AVERAGE BELOW NORMAL...AND LIKELY
WELL BELOW NORMAL ACROSS MUCH THE AREA WEST OF 155W.  THE PATTERN
CONTINUE TO LOOK MAINLY DRY FOR THE FORECAST AREA AS SYSTEMS
GENERALLY MOVE ALONG OR NEAR THE ALEUTIAN CHAIN AND INTO THE GULF OF
ALASKA.  WIND CHILL ISSUES LIKELY AT TIMES THROUGH MUCH OF THE
WEEK...ESPECIALLY ALONG THE WESTERN CAPES AND THROUGH THE BERING
STRAIT.
