NORTHERN ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FAIRBANKS AK
110 PM AKST THU JAN 26 2012

.DISCUSSION...
A DEEP LONG WAVE TROUGH REMAINS PARKED OVER ALASKA. THE TROUGH
WILL CONTINUE TO SLOWLY RETROGRADE WEST AND WEAKEN OVER THE
WEEKEND. WEAK RIDGING DEVELOPS OVER EASTERN ALASKA.

ON THE SURFACE HIGH PRESSURE REMAINS ENTRENCHED OVER THE NORTH
SLOPE AND EASTERN SIBERIA WHILE A WEAK FRONTAL SYSTEM LOCATED 200
NM NORTH OF PABA CONTINUES TO WEAKEN AND MOVE NORTHWARD. A LOW
PRESSURE SYSTEM OVER PWS CONTINUES TO WEAK AS IT DRIFTS NORTHEAST.

A PATCHWORK OF STRATUS OVER THE CENTRAL AND EASTERN INTERIOR IS
SLOWLY ERODING IN SIZE AND RETREATING EASTWARD AS A WEAK TROUGH
OVER THE WESTERN INTERIOR MOVES EASTWARD. MOSTLY CLEAR SKIES
DOMINATE TO THE WEST OF THE TROUGH. CLEAR SKIES COMBINED WITH A
VERY COLD AIR MASS ALOFT ARE CONTRIBUTING TO 40S AND A FEW 50S
BELOW ACROSS THE NORTH SLOPE THE WESTERN INTERIOR AND THE CENTRAL
INTERIOR. NORUTAK LAKE CURRENTLY AT 51 BELOW TAKING HONORS FOR
COLDEST TEMP THIS AFTERNOON IN THE INTERIOR. BARTAR ISLAND
CURRENTLY AT 31 BELOW WITH 20 KTS OF WIND COMBINING FOR WIND CHILL
VALUE NEAR 65 BELOW WHERE A WIND CHILL WARNING REMAINS IN EFFECT.

EXPECT SKIES TO SCATTER OUT ACROSS THE CENTRAL AND EASTERN
INTERIOR AS THE WEAK TROUGH ACROSS THE WESTERN INTERIOR MOVES EAST
TONIGHT AND TOMORROW. THE TEMPERATURES WILL DROP TO THE 40S AND
50S BELOW IN COLDEST LOCATIONS IN THESE AREAS AS THE CLOUDS
RETREAT INTO CANADA.

SYNOPTIC SCALE MODELS ARE STRUGGLING WITH EARLY WEEK PATTERN
CHANGE. CONSIDERABLE SPREAD EXISTS AMONG OPERATIONAL MEMBERS AND
ENSEMBLE MEMBER FOR BOTH THE GFS AND ECMWF. IN THE MEAN AS THE
COLD UPPER LEVEL LOW RETREATS WEST AND NORTHWARD A LOW AMPLITUDE
RIDGE BUILDS OVER THE WEST COAST OF NORTH AMERICA AND INTO BC AND
THE YUKON. A PROGRESSIVE UPPER LEVEL FLOW FROM THE SOUTHWEST SETS
UP OVER ALASKA WHICH WILL ALLOW MULTIPLE SHORT WAVE SYSTEMS TO
MOVE RAPIDLY OUT OF THE NORTHERN PACIFIC AND INTO THE ALEUTIANS
INTO SOUTHWEST ALASKA AND THE NORTHERN GULF OF ALASKA NEXT WEEK.
TIMING AND STRENGTH OF ANY OF THESE SHORT WAVES ARE POORLY
HANDLED AT THIS TIME BY ALL OF THE MODELS LEADING TO BELOW
AVERAGE CONFIDENCE IN THE MID AND LONG RANGE FORECAST.
