SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
215 PM AKST THU FEB 3 2011

.ANALYSIS AND UPPER LEVELS...
THE PATTERN THAT HAS BROUGHT ABUNDANT MOISTURE TO SOUTHCENTRAL AND
SOUTHEAST ALASKA SINCE MONDAY IS FINALLY SHIFTING TO THE EAST TODAY.
THE VERTICALLY STACKED LOW IS CURRENTLY LOCATED NEAR KAMISHAK BAY AND
WILL DRIFT EAST AS IT WEAKENS TONIGHT THROUGH FRIDAY. A SHORTWAVE
TRANSIENT RIDGE IS BUILDING IN ITS WAKE AS ANOTHER LOW PRESSURE
SYSTEM DEVELOPS SOUTH OF THE CENTRAL ALEUTIANS. THE ASSOCIATED
OCCLUDED FRONT WILL BRING WIDESPREAD GALE FORCE WINDS TO THE CENTRAL
AND EASTERN ALEUTIANS THROUGH FRIDAY.

.MODEL DISCUSSION...THE MODELS ARE FINALLY IN EXCELLENT AGREEMENT AND
CONSISTENT FROM PREVIOUS RUNS. THE AFTERNOON PACKAGE WILL REFLECT
ONLY MINOR CHANGES FROM THE INHERITED FORECAST...MAINLY MEDIUM RANGE
DETAILS WITH A DEVELOPING LOW IN THE SOUTHERN GULF. REGARDING THAT
SYSTEM LATER IN THE WEEKEND...WE PREFER THE 12Z ECMWF SOLUTION WHICH
IS INDICATING A SLIGHTLY STRONGER LOW TAKING A MORE NORTH AND
EASTERLY TRACK TOWARD THE PANHANDLE.

.SHORT TERM FORECAST...
.SOUTHCENTRAL...THE VERTICALLY STACKED LOW NEAR KAMISHAK BAY
CONTINUES TO SLOWLY DRIFT EAST. NUMEROUS SNOW SHOWERS ARE FALLING IN
THE VICINITY OF THIS LOW. THE MID AND UPPER LEVEL TEMPERATURES A
DROPPING NEAR THE CENTER OF THE LOW WHILE THE LOW LEVEL TEMPERATURES
REMAIN RELATIVELY WARM...SO LAPSE RATES ARE INCREASING ACROSS THE
SOUTHERN KENAI PENINSULA AND OVER THE NORTHERN GULF COAST. THE
ENHANCED INSTABILITY IS LEADING TO INTENSE SHOWERS REDUCING
VISIBILITY AND LOWERING CEILINGS WHILE PRODUCING BRIEF HIGH SNOWFALL
RATES. THE SHOWERS ARE MOVING FAST ENOUGH THAT ACCUMULATION IS
LIMITED. THE ONE EXCEPTION IS AROUND KACHEMAK BAY WHERE A STEADY BAND
OF MOISTURE SET UP THIS MORNING AND DROPPED 5 TO 9 INCHES OF SNOW
AROUND THE AREA.

AS THE LOW MOVES INTO THE NORTHERN GULF TONIGHT...DRIER AIR WILL
BEGIN TO FILTER ACROSS THE REGION. MOSTLY CLOUDY SKIES WILL GIVE WAY
TO ABUNDANT SUNSHINE THROUGH SATURDAY. A RIDGE BUILDS OVER THE REGION
WITH THE AXIS MOVING OVER SOUTHCENTRAL SATURDAY MORNING. FOG WILL
LIKELY DEVELOP FRIDAY NIGHT THROUGH SATURDAY MORNING OVER PORTIONS OF
SOUTHCENTRAL. THE RIDGE MOVES EAST OF THE REGION SATURDAY NIGHT AND
SUNDAY...ALLOWING THE NEXT WAVE TO APPROACH FROM THE SOUTHWEST.

.SOUTHWEST ALASKA...LIKEWISE THE MOISTURE WRAPPING AROUND THE
BACKSIDE OF THE LOW IS STILL EFFECTING SOME AREAS. LIGHT SNOW
CONTINUES TO BE REPORTED ALONG THE ALASKA AND ALEUTIAN RANGES WITH
FLURRIES ALL THE WAY UP TO THE THE MIDDLE KUSKOKWIM VALLEY. SKIES
WILL CLEAR OVERNIGHT ALLOWING FOG TO DEVELOP AND LIKELY BECOME
WIDESPREAD WITH VISIBILITIES REDUCED TO LESS THAN ONE QUARTER MILE
FOR PLACES ALONG THE COAST.

MOISTURE RETURNS TO THE AREA LATE IN THE WEEKEND AS THE RIDGE SHIFTS
EAST AND THE REMNANTS OF A FRONTAL BOUNDARY APPROACHES FROM THE NORTH
PACIFIC.

.BERING SEA AND ALEUTIANS...GALE FORCE WINDS ASSOCIATED WITH A
FRONTAL BOUNDARY WILL SPREAD ACROSS THE CENTRAL AND EASTERN ALEUTIANS
OVER THE NEXT 24 HOURS. THE PARENT LOW WILL QUICKLY WEAKEN BY
SATURDAY AS IT MOVES INTO THE CENTRAL BERING SEA. WIDESPREAD RAIN AND
SNOW SHOWERS WILL PERSIST THROUGHOUT THE REGION THROUGH THE WEEKEND.

.AER/ALU...WATCH/WARNING SUMMARY
PUBLIC...NONE.
MARINE...GALE WARNING...130 132 155 170 172 175 176
FIRE WEATHER...NONE.
