What forecasters said that day
The local office's own words before this gale warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Anchorage, AK wrote its last area forecast discussion before this gale warning went out at Feb 17, 6:00 PM AKST, 10 hours earlier.
Area forecast discussion, Feb 17, 6:00 PM AKST, 10 hours before
SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
600 PM AKST THU FEB 17 2011
.ANALYSIS AND UPPER LEVELS...
THE PROGRESSIVE PATTERN CONTINUES AS A RESULT OF AN ACTIVE JET
FLOWING OUT OF EASTERN SIBERIA AND ACROSS CENTRAL ALASKA. AN UPPER
LEVEL RIDGE IS NOW IN PLACE OVER SOUTHCENTRAL ALASKA WITH A BROAD
TROUGH CURRENTLY LOCATED OVER THE CENTRAL AND WESTERN BERING SEA.
A FRONTAL BOUNDARY IS ALONG THE BORDER BETWEEN THE TWO FEATURES
EXTENDING FROM THE KUSKOKWIM VALLEY BACK TOWARD THE EASTERN
ALEUTIANS. THE TRANSITORY RIDGE WILL BE PUSHED QUICKLY TO THE
EAST AS THE TROUGH APPROACHES MAINLAND ALASKA.
.MODEL DISCUSSION...MODELS ARE IN EXCELLENT AGREEMENT. MINOR
DIFFERENCES IN TIMING OF THE PRECIPITATION BUT NOTHING THAT WILL
REQUIRE SIGNIFICANT CHANGES FROM THE ONGOING FORECAST.
.SHORT TERM FORECAST...MOISTURE WILL SPREAD OVER SOUTHCENTRAL ALASKA
LATER THIS EVENING. SNOW IS EXPECTED TO DEVELOP FROM THE WESTERN
KENAI UP THROUGH THE SUSITNA VALLEY. THE INTENSITY WILL GRADUALLY
INCREASE AS A 60 KT LOW LEVEL JET MOVES OVER THE REGION...ENHANCING
THE VERTICAL LIFT AROUND MIDNIGHT. SNOWFALL TOTALS WILL HAVE A WIDE
RANGE AS SOUTH AND WEST FACING MOUNTAINS RANGES WILL SEE THE MOST.
EARLY ON IN THE EVENT...A TURNAGAIN ARM WIND WILL LIMIT PRECIPITATION
INITIALLY BUT WILL NOT BE ENOUGH TO OVERCOME THE STRONG AND MOIST
SOUTHWESTERLY FLOW AT THE MID AND UPPER LEVELS.
SNOW SPREADS EAST ACROSS PRINCE WILLIAM SOUND BY MORNING AS A LOW
DEVELOPS ALONG THE FRONTAL BOUNDARY NORTH OF MIDDLETON ISLAND. THIS
LOW REMAINS RELATIVELY STATIONARY UNTIL THE UPPER TROUGH SWINGS
THROUGH FRIDAY NIGHT...ADDING MORE MOISTURE TO THE SYSTEM AND HELPING
INTENSIFY THE SURFACE LOW. THE LOW DRIFTS EAST AS A STRONG SURGE OF
COLD AIR MOVES OVER THE REGION AGAIN SATURDAY AFTERNOON. ANOTHER
TRANSITORY RIDGE BUILDS OVER SOUTHCENTRAL SUNDAY AHEAD OF THE NEXT
TROUGH TO APPROACH EARLY NEXT WEEK.
.SOUTHWEST ALASKA AND BERING SEA...THE SLOW MOVING FRONTAL BOUNDARY
IS DUMPING SNOW ACROSS THE MIDDLE AND UPPER KUSKOKWIM VALLEY AND
APPROACHING BRISTOL BAY. SNOW WILL TAPER OFF FROM WEST TO EAST BY
MORNING...LINGERING ALONG THE ALASKA RANGE THROUGH FRIDAY. CLEARING
ON THE BACKSIDE OF THE FRONT WILL NOT LAST LONG AS THE MAIN TROUGH
SWINGS THROUGH AND RETURNS SNOW SHOWERS TO THE AREA. AGAIN...HIGH
PRESSURE BUILDS SATURDAY BUT IS QUICKLY PUSHED EAST BY THE NEXT
SYSTEM.
A STRONG FRONTAL BOUNDARY APPROACHES THE WESTERN ALEUTIANS FRIDAY
NIGHT...SPREADING STORM FORCE WINDS ACROSS THE WESTERN BERING SEA.
