SIBERIA EASTWARD TO 1040 MB SURFACE HIGH OVER WESTERN CANADA.
PATTERN IS BATHING SOUTHERN HALF OF THE STATE IN STRONG
WESTERLY FLOW ALOFT WITH LIGHTER FLOW ALOFT FOR THE NORTHERN
HALF.

MODELS...REASONABLE CONSENSUS TRANSLATES AMCHITKA CLOSED LOW
EASTWARD TOWARD DUTCH HARBOR PUSHING DOWNSTREAM RIDGE EAST TO THE CANADA
BORDER. ASSOCIATED SURFACE LOW DEEPENS STEADILY UNDER DYNAMIC
SPONSORSHIP FALLING INTO THE 950S MB AS IT MOVES. BROAD SOUTHERLY
FLOW WILL BUILD CHINOOK INTO THE INTERIOR ON TUESDAY AS SURFACE
TROUGH POKES FROM AROUND DUTCH HARBOR NORTHEASTWARD TO KOTZEBUE
SOUND. RIDGE RETREATS LATE TUESDAY TO ALLOW STRAIGHT SHOT FOR
SOUTHERLY FLOW ALOFT ALL THE WAY NORTH TO THE BROOKS RANGE.
SURFACE HIGH PRESSURE BELT WILL SHIFT NORTHWARD TO LIE NORTH OF
THE ARCTIC COAST BY LATE TUESDAY AND KEEPING SURFACE PRESSURE GRADIENT
TIGHT WITH DEEPENING SYSTEM NEAR DUTCH HARBOR. WEDNESDAY
MORNING...DUTCH HARBOR LOW SHIFTS TO BRISTOL BAY TO BEGIN SLOW
ARDUOUS FILLING AS DYNAMIC SPONSORSHIP ERODES.

NORTH SLOPE...STEADY INCREASE IN EAST WIND SPEEDS ON TAP FOR THE
NEXT COUPLE OF DAYS AS ALEUTIAN STORM DEEPENS RAPIDLY NEAR DUTCH
HARBOR AND RELENTLESS HIGH PRESSURE FROM SIBERIA TO WESTERN CANADA

AMCHITKA DEEPENS RAPIDLY TO 950S MB NEAR DUTCH HARBOR BY LATE
TUESDAY INTO WEDNESDAY. LEADING TROUGH FROM ALEUTIANS
NORTHEASTWARD TO NORTON SOUND WILL ALLOW SOUTHWEST FLOW TO PUSH
SHOWERS AND MORE SUBSTANTIAL SNOWS INTO EASTERN NORTON SOUND AND
THE NULATO HILLS. TROUGH WILL TRANSLATE NORTHWARD AND DEEPEN
RAPIDLY ON TUESDAY FROM DUTCH HARBOR TO KOTZEBUE...AND SNOW
WILL BE WIDESPREAD FROM KOTZEBUE SOUTHWARD. THESE WILL CONTINUE
SMEAR NORTHWARD ALONG THE WEST COAST AS SURFACE LOW COILS UP OVER
WESTERN BRISTOL BAY AND TROUGH SWINGS CYCLONICALLYY ABOUT THE
SURFACE CENTER. MARINERS...BRISK WINDS FOR THE NEXT SEVERAL
DAYS...WITH GALES FROM SAINT LAWRENCE ISLAND WESTWARD AND OVER THE
CHUKCHI SEA OUTER WATERS THROUGH WEDNESDAY. THINGS SHOULD START

MEDIUM RANGE...PLAUSIBLE SOLUTION SHEARING BIG TROUGH EASTWARD INTO
CANADA WITH WEAK RIDGE BUILDING NORTHWARD INTO THE SOUTHERN BERING
SEA BY THE WEEKEND. PATTERN SHOULD BE CALMER ACROSS THE
BOARD...FAST FLOW DISPLACED TO THE SOUTH WILL REDUCE DYNAMIC
SUPPORT FOR ORGANIZED SNOWFALL...WEAK EASTERLY FLOW WILL RETURN TO
THE INTERIOR. SURFACE LOW NEAR MACKENZIE DELTA LATE IN THE WEEK
