AREA FORECAST DISCUSSION
SOUTHCENTRAL AND SOUTHWEST ALASKA
500 AM AST SAT JAN 5 2008

.ANALYSIS AND UPPER LEVELS...
COLD CORE UPPER LEVEL LOW REMAINS OVER NORTHWESTERN ALASKA WITH A
TROUGH EXTENDING DOWN INTO THE FAR EASTERN GULF AND ALONG THE WEST
COAST OF NORTH AMERICA. UPPER LEVEL RIDGE EXTENDS FROM EASTERN
SIBERIA DOWN OVER THE CENTRAL ALEUTIANS INTO THE NORTH PACIFIC.
ANOTHER UPPER LEVEL LOW IS BETWEEN THE KAMCHATKA PENINSULA AND THE
WESTERN ALEUTIANS.
AT THE SURFACE...A BROAD TROUGH STRETCHES OVER THE GULF DOWN TO A LOW
ANCHORED NEAR THE QUEEN CHARLOTTE ISLANDS. A WEAK DISSIPATING LOW IN
THE CENTRAL GULF HAS BROUGHT LIGHT SNOW TO KODIAK ISLAND OVERNIGHT. A
RIDGE IS DRAPED OVER THE CENTRAL BERING AND ALEUTIANS KEEPING BROAD
NORTHWESTERLY FLOW OVER THE EASTERN BERING. A STRENGTHENING LOW IS
JUST EAST OF THE TIP OF THE KAMCHATKA PENINSULA AND MOVING NORTHEAST.

.MODEL DISCUSSION...
OVERALL MODELS ARE IN GOOD AGREEMENT WITH THE RUN TO RUN CONSISTENCY
OF THE GFS MODEL BEING THE BEST. THEREFORE WAS ABLE TO USE THE
EXISTING FORECAST OR TRENDED TOWARD THE LATEST GFS RUN FOR THIS
FORECAST PACKAGE.

.SHORT TERM FORECAST...
SOUTH AND EAST OF THE ALASKA RANGE...WEAK SURFACE PATTERN IS AIDING
IN AREAS OF FOG DEVELOPING MAINLY ALONG COOK INLET AND THE KNIK ARM.
LOW VISIBILITIES SHOULD DIMINISH BY THE AFTERNOON. THE LOW NEAR THE
QUEEN CHARLOTTE ISLAND IS PROGGED TO MOVE NORTHWEST INTO THE
NORTHWESTERN GULF BY SUNDAY. SNOW SHOWERS ARE EXPECTED MAINLY ON THE
OUTER PORTIONS OF THE GULF COAST AT FIRST. THEN A STRONG SHORTWAVE
MOVES NORTH THROUGH THE GULF AND INCREASES THE AMOUNT OF
PRECIPITATION AND PUSHES INLAND TO AFFECT SOUTHERN COPPER RIVER
BASIN...KENAI PENINSULA AND PRINCE WILLIAM SOUND AREA SUNDAY NIGHT
THEN CONTINUES THROUGH MONDAY BEFORE THE LOW PULLS SOUTH INTO THE
GULF. THE PATTERN DOES NOT LOOK GREAT FOR SNOW IN THE ANCHORAGE BOWL
FOR SUNDAY NIGHT AND MONDAY...HOWEVER WILL MOST LIKELY SEE SCATTERED
SHOWERS. KODIAK WILL REMAIN IN GUSTY COLD NORTHWESTERLY FLOW LIKELY
TO REACH GALE FORCE AT TIMES. SNOW WILL BE ENDING TODAY AS THE NEARBY
WEAKENING LOW MOVES FURTHER EAST AND DIMINISHES.

WESTERN MAINLAND AND ALASKA PENINSULA...GUSTY COLD NORTHWESTERLY FLOW
CONTINUES OVER THE MAINLAND. A FAIRLY STRONG SHORTWAVE WILL BE MOVING
EAST OVER THE AREA TO INCREASE WINDS TODAY. MOST AREAS WILL BE
STAYING MAINLY DRY EXCEPT SNOW SHOWERS ALONG THE COASTAL AREAS AND
LIGHT SNOW OVER NORTHERN KUSKOKWIM VALLEY.

BERING AND ALEUTIANS...SNOW SHOWERS IN THE NORTHWESTERLY FLOW WILL
CONTINUE THROUGH TONIGHT OVER THE EASTERN BERING AND ALEUTIANS AS THE
CENTRAL BERING RIDGE PUSHES EAST. WEATHER FRONT FROM THE LOW NEAR
KAMCHATKA PENINSULA WILL BRING GALE FORCE WINDS AND A RAIN AND SNOW
MIX TO THE WESTERN ALEUTIANS BEGINNING TODAY THEN MOVING EAST OVER
THE CENTRAL ALEUTIANS SUNDAY. THE RIDGE SHOULD HOLD OFF ANY FURTHER
EAST PROGRESSION.

.LONG TERM FORECAST...UPPER LEVEL PATTERN LOOKS TO CONTINUE
RELATIVELY THE SAME THROUGHOUT MID NEXT WEEK...LOW OR TROUGH OVER THE
MAINLAND AND A RIDGE OVER THE CENTRAL BERING AND ALEUTIANS WITH A FEW
SURFACE SYSTEMS AFFECTING THE WESTERN ALEUTIANS. CONTINUED COLD
TEMPERATURES FLOWING OVER WESTERN MAINLAND AND SEVERAL WEAK SYSTEMS
IN THE GULF.
