Gale Warning 20, NWS Fairbanks, AK

NORTHERN ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FAIRBANKS AK
525 AM AKST MON JAN 28 2013

.DISCUSSION...
MODELS SIMILAR THROUGH 48 HOURS. COLD TROUGH OVER ALASKA WILL
MIGRATE NORTHWARD TODAY AS UPPER LEVEL RIDGE BEGINS TO PUSH
NORTHWARD. STRONG LOW IN ON THE ALEUTIANS IS MOVING NORTHWARD WITH
OCCLUDED FRONT EXTENDING NORTH TO THE CENTRAL INTERIOR AND ALONG
THE WEST COAST. THIS WILL CREATE SUBSTANTIALLY WARMER AIR PUSHING
ACROSS THE CENTRAL PORTION OF THE STATE AND THE PRECIPITATION BAND
WORKING UP ALONG THE WEST COAST.

AS THE LOW ON THE ALEUTIANS MOVES NORTH IT WILL REACT WITH THE
HIGH PRESSURE OVER NORTHERN ALASKA AND CREATE A TIGHT PRESSURE
GRADIENT OVER NORTHERN ALASKA. THIS IS GOING TO INCREASE WINDS IN
SOME OF THE INTERIOR AREAS TO SUCH A DEGREE THAT WIND CHILL
ADVISORIES WILL PROBABLY BE LIKELY IN A FEW OF THE ZONES.

AS THE FRONT MOVES NORTH...IT WILL MOVE RATHER SLOWLY AND SPREAD
SEVERAL INCHES OF SNOW OVER THE WEST COAST AND WESTERN INTERIOR
THROUGH THE END OF THE WEEK. THE WARMER AIR WILL LIKELY BE
FOLLOWED BY ANOTHER SURGE OF COLDER AIR PUSHING SOUTH FOR NEXT WEEKEND.
