Area forecast discussion, Jan 22, 5:00 AM AKST, 11 hours before

SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
500 AM AKST SAT JAN 22 2011

.MODEL DISCUSSION...

MODELS ARE IN DECENT AGREEMENT THROUGH THE SHORT TERM. PROBLEMS BEGIN
TO ARISE IN TIMING OF THE MANY SHORTWAVES AND ASSOCIATED SURFACE
FRONTS/LOWS MOVING NORTH THROUGH THE GULF ON THE EAST SIDE OF A
QUASI-STATIONARY LOW PRESSURE SOUTH OF THE EASTERN ALEUTIANS BY THE
END OF THE WEEKEND INTO EARLY NEXT WEEK. THE FORECAST LEANS TOWARDS
THE NAM AND GFS IN THE SHORT TERM...THEN TOWARDS THE EUROPEAN
MODEL(EC) FROM MONDAY NIGHT ONWARDS.

.ANALYSIS AND UPPER LEVELS...

A POTENT UPPER LEVEL DISTURANCE IS LOCATED IN THE NORTHERN GULF THIS
MORNING WITH AN ASSOCIATED 981 MB SURFACE LOW. THESE FEATURES WILL
MOVE NORTH AND EAST TOWARDS YAKUTAT AND THEN INLAND LATE THIS MORNING
OR EARLY THIS AFTERNOON. A MORE SUBTLE DISTURBANCE IS LOCATED OVER
THE SOUTHWESTERN MAINLAND AND WILL MOVE EAST ACROSS SOUTHCENTRAL THIS
MORNING AND THE NORTHERN GULF COAST THIS AFTERNOON. LIGHT
PRECIPITATION WILL CONTINUE ACROSS SOUTHCENTRAL UNTIL THIS SECOND
DISTURBANCE PASSES AND LARGELY DIMINISHES PRECIPITATION FROM WEST TO
EAST...THOUGH A FEW SHOWERS CAN'T BE RULED OUT (ESPECIALLY OVER THE
MOUNTAINS) THIS EVENING AND TONIGHT AS ANOTHER DISTURBANCE MOVES
NORTH JUST AHEAD OF A TRANSITORY UPPER LEVEL RIDGE WHICH MOVES OVER
THE AREA TONIGHT.

MEANWHILE...A STRONG LOW PRESSURE SYSTEM IN THE NORTH PACIFIC WILL
MOVE TO ABOUT 375 NAUTICAL MILES SOUTH OF THE EASTERN ALEUTIANS BY
SUNDAY NIGHT...AND THEN BECOMES MOSTLY STATIONARY. POTENT UPPER LEVEL
DISTURBANCES WILL USHER QUICK-MOVING FRONTS NORTH FROM ABOUT 170W
LONGITUDE EAST THROUGH THE GULF AND EXTENDING NORTH TO BRISTOL BAY
AND THE SOUTHERN MAINLAND BEGINNING THIS EVENING. THE FIRST IN A
SERIES OF FRONTS WILL REACH THE GULF COAST LATE SUNDAY NIGHT AND
EXTEND SOUTH AND WEST THROUGH BRISTOL BAY AND ACROSS THE EASTERN
ALEUTIANS. THIS SYSTEM WILL REPRESENT THE LEADING EDGE OF WARMER
MARITIME AIR AT THE SURFACE AS IT MOVES INLAND OVER SOUTHCENTRAL
BEFORE DISSIPATING.

.SHORT TERM FORECAST...

SOUTHCENTRAL...

A SERIES OF DISTURBANCES WILL AFFECT THE REGION TODAY. THE FIRST
CONTINUES TO MOVE INLAND AND WILL BRING DECENT AMOUNTS OF SNOW FROM
PRINCE WILLIAM SOUND NORTH AND EAST...WITH RAIN ALONG THE IMMEDIATE
COAST WITH WARM ONSHORE FLOW. VERY WEAK COLD ADVECTION AND A RESIDUAL
PRINCE WILLIAM SOUND LOW WILL ALLOW FOR CONTINUED LIGHT SNOWFALL
THROUGH THIS MORNING OVER THE ANCHORAGE AND MAT-SU VALLEY AREAS.
SATURATION IN THE SNOW GROWTH LAYER ALOFT IS LIMITED TO A RATHER
SHORT DURATION THIS MORNING...AND IS NOT FAVORABLE FOR ANYTHING MORE
THAN LIGHT SNOW ACCUMULATIONS FOR THE COOK INLET REGION TODAY.
ANOTHER QUICK MOVING DISTURBANCE ON THE FRONT SIDE OF THE APPROACHING
UPPER RIDGE WILL PRESENT AT LEAST A SLIGHT CHANCE OF SNOW SHOWERS
OVER THE REGION TONIGHT.

ATTENTION THEN SHIFTS TO THE GULF LATE SATURDAY NIGHT INTO SUNDAY
MORNING AS THE FIRST IN A SERIES OF SYSTEMS MOVES NORTH FROM THE
PACIFIC. THIS SYSTEM WILL BRING A RENEWED SHOT OF SNOW WITH RAIN
ALONG THE IMMEDIATE COAST AS IT MOVES INLAND SUNDAY NIGHT. EXPECT
WINDS TO PICK UP ENOUGH THROUGH TURNAGAIN ARM TO PRODUCE STRONG
WINDS...AND STORM FORCE WINDS IN THE USUAL BARRIER JET REGION OVER
THE NORTHERN GULF. AS THE FRONT MAKES ITS WAY INLAND...WARM MARITIME
AIR SHOULD WORK ITS WAY NORTHWARD...BRINGING TEMPERATURES WELL INTO
THE 30S TO ANCHORAGE AND THE MAT-SU VALLEY...AND WITH THIS WILL COME
LIKELY A MIX OF RAIN AND SNOW.

SOUTHWEST...

SUBTLE UPPER LEVEL DISTURBANCE IS BRINGING A MIX OF LIGHT SNOW AND
FREEZING DRIZZLE ALONG WITH FOG TO THE BRISTOL BAY REGION. THIS
SHOULD END BY THE AFTERNOON WITH CLEARING SKIES. A STRONG FRONT
APPROACHES FROM THE LATE TONIGHT INTO EARLY SUNDAY AND WILL BRING A
RENEWED CHANCE OF RAIN AND SNOW TO THE BRISTOL BAY REGION.
OTHERWISE...BRISK NORTHERLY WINDS TO THE NORTHWEST OVER THE KUSKOKWIM
DELTA REGION ALONG WITH COLD ADVECTION WILL CONTINUE TO SUPPORT WIND
CHILLS 40 BELOW TO 50 BELOW THROUGH AT LEAST SUNDAY MORNING...AND
POSSIBLY BEYOND.

BERING SEA REGION...

MOST OF THIS REGION WILL LIE ON THE BACK SIDE OF THE STRONG LOW IN
THE NORTH PACIFIC. AS THE FIRST FRONT IN A SERIES MOVES INTO THE
EASTERN BERING...STRONG WINDS WILL PICK UP AT FIRST THIS EVENING OVER
THE PRIBILOFS...FOLLOWED BY LIGHT SNOW OVER THE REGION BY LATE
TONIGHT OR EARLY SUNDAY MORNING. BLIZZARD CONDITIONS ARE A GOOD BET
FOR MOST OF THE DAY ON SUNDAY INTO SUNDAY NIGHT. THUS...A BLIZZARD
WATCH FOR THE PRIBILOFS WILL BE ISSUED WITH THE MORNING FORECAST
PACKAGE. OTHERWISE...COLD ADVECTION SNOW SHOWERS WILL CONTINUE
THROUGH THE REMAINDER OF THE SHORT TERM INTO THE MIDDLE OF NEXT WEEK.

.LONG TERM FORECAST...

NEARLY STATIONARY LOW PRESSURE OVER THE SOUTHERN BERING/NORTH PACIFIC
REGION THROUGH THE EXTENDED PERIOD WILL MOVE DISTURBANCES/SYSTEMS
OVER THE MAINLAND...KEEPING CONDITIONS MUCH WARMER AND WETTER THAN
NORMAL THROUGH THE END OF THE WEEK.
