What happened

The episode as NWS AFC wrote it up.

Strong high pressure over interior Alaska combined with a rapidly deepening low in the Gulf of Alaska resulted in strong northerly wind across the south central region and northern gulf coast of Alaska. Strong wind is estimated to have reached around 90 mph out of the Copper River Delta based upon satellite interpretation and the magnitude of the wind observations in and around the north gulf coast. The north wind reached 86 mph in the Palmer and Wasilla area as a result of the channeling down the Matanuska Valley. Drifting snow and sand resulted in the derailment of the Alaska Railroad train at the junction of the Parks Highway resulting in closing the Parks Highway for several hours. The northerly wind peaked at 64 mph over Fire Island, just west of Anchorage International Airport. As the low in the Gulf of Alaska moved to the west it brought moderate to heavy snow to Kodiak island along with winds gusting 30 to 40 mph causing a blizzard over the Island for over 3 hours on the afternoon of the 7th.

SOUTH/SOUTHWEST ALASKA FORECAST DISCUSSION
900 PM AST MON JAN 5 2004

.DISCUSSION...UPPER LEVEL HIGH CENTER POSITIONING ITSELF OVER THE
CHUKOTSK PENINSULA AS SHORT WAVE TROUGH PUSHING THROUGH THE INTERIOR
TONIGHT. THE BIG STORY REMAINS THE STRONG WINDS ANTICIPATED OVER
SOUTH CENTRAL ALASKA BEGINNING LATER TONIGHT AND REMAINING POSSIBLY
INTO WEDNESDAY MORNING. LATEST RUN HAS STRONGEST WINDS AT ALL LEVELS
A BIT FARTHER WEST TO LINE UP MORE WITH THE JET CORE OVER WESTERN
ALASKA, THE JET CORE IS CURRENTLY FROM BARROW TO DENALI...BUT BY
WEDNESDAY MORNING WILL BE ORIENTED NORTH SOUTH FROM BARROW TO BETHEL.
GOOD TEMP ADVECTION WITH SHORT WAVE AND A STRONGER SURFACE PRESSURE
GRADIENT DEVELOPS OVER THE SOUTH CENTRAL COAST RATHER THAN ANYWHERE
ELSE. THIS IS DUE TO THE AREA OF LOW PRESSURE IN THE NORTHERN PACIFIC
BEING PULLED NORTHEAST COMBINED WITH THE UPPER LEVEL LOW DROPPING
INTO THE GULF. EVEN WITH THE STRONGEST WINDS ALOFT REMAINING WEST OF
ANCHORAGE...STILL HAVE A VERY FAVORABLE PRESSURE GRADIENT...STRONG
TEMP ADVECTION...STRONG WINDS ALOFT AND A SHORT WAVE MOVING THROUGH.
THEREFORE...FEEL WIND WARNINGS AND ADVISORIES SHOULD WORK OUT JUST
FINE TOMORROW.

UPPER LOW CARVES OUT IN THE GULF WEDNESDAY INTO THURSDAY AS SURFACE
LOW PICKS UP STRENGTH IN THE WESTERN GULF. THE UPPER HIGH GETS
PINCHED OVER EASTERN SIBERIA BY THIS TIME AS WELL. THEREFORE THE
DOMINANT FEATURE OVER THE ENTIRE FORECAST AREA BECOMES THE COLD UPPER
LEVEL LOW. THE UPPER LEVEL LOW THEN SLOWLY DRIFTS SOUTHWEST ALONG THE
ALEUTIAN CHAIN THROUGH FRIDAY MORNING AND THEN NORTHWEST OVER THE
WEEKEND ENDING UP IN THE NORTHERN BERING BY SUNDAY. AT THE SURFACE
THE LOW FOLLOWS MUCH THE SAME PATH AS IS CHARACTERISTIC OF A DEEP
COLD LOW. PRECIP WILL BE WRAP AROUND THE LOW AS IT MOVES SOUTHWEST
OVER THE ALASKA PENINSULA THURSDAY NIGHT/FRIDAY.

OVER THE WEST...A SERIES OF LOW CENTERS MOVING WEST NORTHWEST THROUGH
THE CENTRAL AND WESTERN ALEUTIAN KEEPING THE PRESSURE GRADIENT
FAVORABLE FOR MODERATE TO STRONG SOUTHEAST WINDS. IN ADDITION...THE
ARCTIC COLD FRONT WHICH WILL PUSH THROUGH CENTRAL ALASKA TONIGHT AND
TUESDAY WILL MOVE ALL THE WAY PASSED THE PRIBILOF ISLANDS WEDNESDAY.
THIS WILL KEEP WINDS STRONG FROM THE EAST/NORTHEAST. SHOWERS WILL BE
ON THE DECREASE TUESDAY AFTERNOON AS THE LAST OF THE NORTH PACIFIC
LOWS LIFTS NORTHWEST TO EASTERN SIBERIA DUE TO THE PROGRESSION OF THE
COLD LOW OVER THE GULF. SHOWER ACTIVITY BEYOND THIS TIME FRAME WILL
BE ASSOCIATED WITH THE SLOW PROGRESSION OF THE COLD LOW.
