SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
500 AM AKST THU FEB 9 2012

.MODEL DISCUSSION...
OVERALL THE MODELS ARE IN GOOD AGREEMENT THIS MORNING...AT LEAST
THROUGH SATURDAY. THE NAM IS THE OUTLIER WITH THE LOW IN THE EASTERN
GULF...AND THE GFS AND ECMWF ARE FAIRLY SIMILAR. THERE ARE THEN SOME
DISAGREEMENTS OVER LOW TRACKS AND INTENSITIES IN THE PACIFIC...AND
CONFIDENCE SUBSEQUENTLY DECREASES WITH THAT PORTION OF THE FORECAST.
OVERALL...THE GFS WAS THE MODEL OF CHOICE THROUGH SATURDAY
NIGHT...AND THEN THE ECMWF WAS THE MODEL OF CHOICE BEYOND THAT.

.ANALYSIS AND UPPER LEVELS...
MUCH OF MAINLAND ALASKA IS BETWEEN THE UPPER RIDGING OF WESTERN
CANADA AND THE LONGWAVE TROUGH OVER THE BERING SEA. THIS GENERAL
PATTERN WILL CONTINUE OVER THE NEXT SEVERAL DAYS...WITH LOWS MAINLY
AFFECTING THE ALEUTIANS AND SOUTHERN MAINLAND. THE SOUTH AND
SOUTHEAST FLOW IS BRINGING RELATIVELY WARM AIR TO THE SOUTHERN HALF
OF THE STATE...AND IS RESULTING IN PRECIPITATION THAT IS RAIN OR
FREEZING RAIN IN SOME LOCATIONS. THE MAIN SURFACE FEATURE OF NOTE
THIS MORNING IS JUST SOUTH OF THE ALASKA PENINSULA.

.SHORT TERM FORECAST...
.SOUTHCENTRAL...
THE AFOREMENTIONED LOW CURRENTLY MOVING INTO THE GULF IS GOING TO
BRING PRECIPITATION TO THE GULF COAST AHEAD OF A FRONT OVER THE NEXT
COUPLE DAYS. THERE IS A CHANCE FOR BLIZZARD CONDITIONS AROUND PORTAGE
ON SATURDAY...HOWEVER THIS IS HIGHLY DEPENDENT ON TEMPERATURES
ACCOMPANYING THE PRECIPITATION. INDICATIONS AT THIS POINT LEAN TOWARD
A WARM SOLUTION...HOWEVER THIS IS SOMETHING TO KEEP AN EYE ON.

.SOUTHWEST ALASKA AND ALEUTIAN ISLANDS...
THE MAIN CONCERN FOR SOUTHWEST ALASKA IS WINDS ALONG THE ALASKA
PENINSULA TODAY. WITH STRONG SUBSIDENCE...THERE SHOULD BE SOME WINDS
IN EXCESS OF 75 MPH SOUTH OF KING SALMON. THAT LOW WILL DISSIPATE IN
THE SOUTHERN BERING SEA TOMORROW...AND ANOTHER STRONGER LOW WILL MOVE
NORTHEASTWARD TOWARD THE CENTRAL ALEUTIANS ON FRIDAY. WITH THIS NEXT
LOW...MORE RAIN...SNOW...AND WIND WILL AFFECT THE SOUTHWEST MAINLAND
AND SOUTHERN BERING.

.LONG TERM FORECAST...
A MORE ACTIVE PATTERN WITH A CONTINUOUS STREAM OF LOWS MOVING ACROSS
THE REGION FROM THE WEST. THERE IS A LOT OF UNCERTAINTY AMONG THE
MODELS IN THIS PORTION OF THE FORECAST...SO VERY FEW CHANGES WERE
MADE TO THE FORECAST.

.AER/ALU...WATCH/WARNING SUMMARY

MARINE...GALE WARNING...130 132 138 155 160 170 180
