AREA FORECAST DISCUSSION
SOUTHCENTRAL AND SOUTHWEST ALASKA
500 AM AST TUE DEC 4 2007

.ANALYSIS AND UPPER LEVELS...

CLOSED UPPER LOW OVER THE BERING AND WESTERN AK THIS MORNING...WITH
ANOTHER OVER THE KAMCHATKA PENINSULA. AN UPPER RIDGE IS OVER THE
ROCKIES WITH A WEAK UPPER RIDGE OVER THE WESTERN BERING. AT THE
SURFACE...SMALL LOWS ARE OVER THE EASTERN BERING AND NEAR KODIAK
ISLAND WITH A MUCH DEEPER LOW WEST OF ATTU.

.MODEL DISCUSSION...

MODELS ARE IN GOOD AGREEMENT FOR THE FIRST SEVERAL DAYS. THE FORECAST
FOLLOWS THE GFS DURING THIS PERIOD. THE KODIAK LOW MOVES TO THE KENAI
AND IS PRECEDED BY A FRONT MOVING INTO THE NORTH GULF COAST TODAY.
THE BERING LOW MOVES INLAND AND THE ASSOCIATED RAPIDLY DECAYING FRONT
CROSSES THE AK AND ALEUTIAN RANGES WED. THE LOW NEAR ATTU MOVES INTO
THE BERING TODAY WITH THE ASSOCIATED FRONT REACHING WESTERN AK
TONIGHT...AND CROSSING THE ALEUTIAN RANGE THU. A PAIR OF NORTH
PACIFIC LOWS CROSS THE WESTERN AND EASTERN ALEUTIANS FRI. AT THIS
POINT THE GFS IS REPLACED BY THE ECMWF WHICH HAS SHOWN BETTER RUN TO
RUN CONSISTENCY...MERGING THE TWO LOWS IN THE CENTRAL BERING AND
LEAVING THE NEW LOW TO SLOWLY WEAKEN THROUGH THE WEEKEND. A LOW ALSO
MOVES INTO THE GULF EARLY NEXT WEEK.

.SHORT TERM FORECAST...

IN THE WEST...AS THE ATTU LOW MOVES INTO THE BERING IT WILL BRING
HURRICANE FORCE WINDS TO THE WESTERN ALEUTIANS THROUGH WED WITH
STORMS AND GALES PERSISTING INTO THU AS IT TRACKS NORTHEAST. SNOW
WILL MIX WITH RAIN AND THEN CHANGE BACK TO SNOW SHOWERS AS THE LOW
PASSES. HIGH PRESSURE BUILDS BRIEFLY INTO THE AREA THU BEFORE THE
MERGING PACIFIC LOWS BRING ANOTHER ROUND OF GALES AND STORMS FRI AND
SAT.

OVER SW AK...

WRAPAROUND SHOWERS FROM THE KODIAK LOW WILL AFFECT THE ALEUTIAN RANGE
TODAY WHILE THE FRONT FROM THE BERING LOW BRINGS SNOW AND WIND TO
COASTAL SECTIONS. BRIEF DRYING WILL OCCUR THIS EVENING BEFORE THE
MAJOR FRONT FROM THE ATTU LOW ARRIVES. THIS WILL BRING SNOW CHANGING
TO RAIN ALONG WITH STRONG WINDS TO THE COAST WED. ONSHORE FLOW
DEVELOPS THU AFTER THE FRONT MOVES EAST BRINGING ANOTHER ROUND OF
SNOW INLAND. THE FRONT WITH THE MERGING PACIFIC LOWS WILL BRING SNOW
SHOWERS FROM THE EAST ACROSS THE ALEUTIAN AND AK RANGES FRI.

SOUTH AND EAST OF THE AK RANGE...THE FRONT ASSOCIATED WITH THE KODIAK
LOW WILL BRING STRONG WIND TO THE NORTH GULF COAST TODAY AND TONIGHT
WITH ABUNDANT SNOWFALL. THIS WILL BRING BLIZZARD CONDITIONS TO THE
KENAI...EASTERN TURNAGAIN ARM AND THOMPSON PASS TODAY. CONDITIONS
WILL IMPROVE BRIEFLY EARLY WED AND THEN THE ATTU FRONT ARRIVES WITH
ANOTHER ROUND OF RAIN AND SNOW FOR THE NORTH GULF COAST. THIS FEATURE
IS MORE FAVORABLE FOR SNOWFALL INTO SOUTH CENTRAL. IMPROVEMENT IS
AGAIN EXPECTED FRI.

.LONG TERM FORECAST...

IN THE WEST THE LOW MOVES INTO THE BERING AND KEEPS SNOW SHOWERS IN
THE AREA THROUGH THE WEEKEND. OVER SW AK...THE ASSOCIATED FRONT FROM
THE BERING LOW WILL BRING SNOW SHOWERS. IN THE EAST...COASTAL RAIN
AND SNOW WILL ACCOMPANY THE SAME FRONT WITH PRECIP CROSSING THE
COASTAL MOUNTAINS DURING THE WEEKEND.
