NORTHERN ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FAIRBANKS AK
500 AM AST THU FEB 22 2007

.DISCUSSION...DEEP COLD 495 DM UPPER LOW NOW CENTERED
JUST S OF MACKENZIE DELTA INLAND E OF OLD CROW. ONLY
MOISTURE ASSOCIATED WITH IT ARE MID/HIGH CLOUDS FROM
SHORT-WAVE DROPPING S ON BACK-SIDE OF IT OVER CENTRAL
INTERIOR.

MODELS DIFFER TO SOME DEGREE IN SHORT-TERM ON PLACEMENT
AND DURATION OF UPPER LOW...BUT ACTUALLY RESOLVE THESE AND
COME TOGETHER BETTER IN MID/LONGER TERM. NAM AND ECMWF
KEEP UPPER LOW IN PLACE THROUGH SAT OVER YUKON/ALCAN BORDER
AREA...WHILE GFS SPLITS LOW FRI WITH MAIN PORTION RETREATING
BACK NWRD OVER ARCTIC IN RESPONSE TO SHORT-WAVE MOVING ESE FROM
SIBERIA UNDERCUTTING IT. AT THIS TIME STILL PREFER NAM/ECMWF
SOLUTION...AS IT IS MORE CONSISTENT AND INITIALIZES A LITTLE
BETTER.

COLD -30 TO -34C AIR THEN WILL REMAIN OVER ERN HALF N SLOPE
AND CENTRAL/ERN INTERIOR UNTIL ABOUT 00Z SUN. LITTLE IN THE
WAY OF CLOUDS WILL KEEP TEMPS. VERY COLD THESE AREAS THROUGH
THEN. FIRST SIGNIFICANT CHANGE TO PATTERN WILL BE A SHORT-WAVE
ALL MODELS FORECAST TO SLIDE E FROM SIBERIA OVER CHUKCHI SEA
FRI...THEN SE TOWARD WRN GULF AK/S-CENTRAL AK SAT. THIS WILL
BRING SOME -SN TO MOST OF W COAST FRI...AND AT LEAST SOME
FLURRIES TO WRN INTERIOR FRI NIGHT. RESIDUAL CLOUDS FROM THIS
AND WEAK DYNAMICS WILL BRING CLOUDS OVER INTERIOR E TO ABOUT
PARC-PAFA SAT...AND POSSIBLY SOME FLURRIES. THIS WOULD ALSO
MODERATE TEMPS. A BIT.

MODELS ALSO CONSISTENT AND AGREE IN SHOWING MUCH STRONGER
WAVE WITH STRONG CONSOLIDATED WRLY JET FLOW ROARING E FROM
SIBERIA SUN/MON. THIS WOULD BRING MORE SIGNIFICANT SNOWFALLS
TO W COAST/WRN INTERIOR SUN/SUN NIGHT...AND TO INTERIOR MON.
THIS KIND OF STRONG WAVE WITH FAST CYCLONIC WSWRLY LOW-MID
LEVEL FLOW COULD BE HEAVY SNOW PRODUCER FOR AREAS LIKE PATA-
PAFA. ONLY PROBLEM IS TRAJECTORY OF THIS FLOW IS MOSTLY OVER
ICE-COVERED BERING...AND MOISTURE AVAILABILITY WOULD LIKELY
BE LIMITED. BUT SHOULD BE GOOD ENOUGH FOR AT LEAST 1-2 INCHES
SNOW ANYWAY FOR CENTRAL INTERIOR MON E TO ABOUT SALCHA.
MODERATION OF TEMPS. WILL BE FULLY UNDERWAY FOR INTERIOR SAT.
EVENING THROUGH MON. WITH INCREASING CLOUD COVER AND RETREAT
OF COLDEST AIR E INTO CANADA.

COASTAL HAZARD POTENTIAL DAYS 3 AND 4...NONE
