.DISCUSSION...
MODELS IS DISARRAY AS THE MODELS ARE INCONSISTENT BY VARYING FROM
RUN TO RUN AND NOT IN GOOD AGREEMENT WITH EACH OTHER PAST 48 HOURS.
WHAT DOES APPEAR IS THAT THERE IS A VERY COLD UPPER LEVEL LOW
CENTERED OVER NORTHWESTERN ALASKA THAT WILL MOVE TO ABOUT THE
SEWARD PENINSULA BY FRI AFTERNOON. THIS WILL PULL VERY COLD AIR
DOWN THROUGH WESTERN ALASKA THROUGH THE WEEKEND. A REINFORCING
SHOT OF VERY COLD AIR IS ADVERTISED TO MOVE DOWN ALONG THE WEST
COAST LATER THIS WEEKEND THOUGH.

LOW MOVING INTO SOUTHWESTERN ALASKA THIS EVENING WILL PROVIDE A
FEW INCHES OF SNOW IN THE YK DELTA REGION BEFORE MOVING EASTWARD
TO SOUTH CENTRAL ALASKA BY FRI AFTERNOON. THIS LOW AND ASSOCIATED
FRONTAL SYSTEM WILL COMBINE WITH THE UPPER LEVEL LOW WESTERN
ALASKA WILL PUSH SNOW INTO THE CENTRAL PORTION OF NORTHERN ALASKA
BY SAT MORNING. SURFACE HIGH PRESSURE WILL FALL IN DIRECTLY BEHIND
THE FRONT AND BEGIN TO CLEAR OUT THE CLOUDS VERY QUICKLY BEGINNING
FROM THE WEST FRI NIGHT.

A COUPLE OF FRONTS WILL MOVE ACROSS THE AREA THROUGH THE FIRST
PART OF NEXT WEEK SPREADING SNOWFALL WITH COLD AIR SLIDING IN
BEHIND THE FRONTS.
