MODELS REMAIN IN GOOD AGREEMENT THROUGH THE SHORT TERM. THE UPPER
LEVEL RIDGE CENTERED OVER EASTERN ALASKA AND THE YUKON WILL SLOWLY
MOVE EASTWARD THROUGH THE WEEKEND WHILE A WEAK SHORT WAVE
CURRENTLY OVER THE LOWER YK DELTA MOVES NORTH ALONG THE WEST
COAST AND THEN EAST OVER THE NORTH SLOPE WHILE OVER TOPPING THE
RIDGE AND COMBINING WITH A DEVELOPING LONG WAVE TROUGH THAT MOVES
SOUTH AND EAST OUT OF THE HIGH ARCTIC OVER THE WEEKEND AND THEN
DIGS SOUTHWEST OVER THE STATE EARLY NEXT WEEK. THIS COLD UPPER
LEVEL TROUGH WITH AN AXIS FROM NUNIVAK ISLAND TO DEMARCATION POINT
WILL REMAIN OVER NORTHERN ALASKA THROUGH NEXT WEEK. EXPECT BELOW
NORMAL TEMPERATURES NEXT WEEK ON THE NORTH SLOPE AS WELL AS THE
NORTHERN AND EASTERN INTERIOR AS COLD AIR MASS SETTLES OVER
NORTHERN ALASKA. 850 MB TEMPERATURES DIP INTO THE 20S BELOW NORTH
OF THE BROOKS RANGE AND TEMPERATURES IN THE TEENS BELOW AT 850 MB

THE 30S BELOW IN COLDEST LOCATIONS IN THE NORTHEAST INTERIOR NEXT
WEEK WHILE MUCH OF THE CENTRAL AND EASTERN INTERIOR WILL SEE LOWS
DIPPING INTO THE 20S BELOW.

THE SURGE OF WARM AIR ALOFT ALONG THE WEST COAST CONTINUES TO MOVE
NORTH AND EAST AS COLDER AIR ALOFT MOVES EASTWARD ALONG THE WEST
COAST CHANGING ANY REMAINING RAIN OR FREEZING RAIN BACK TO ALL

THE SEWARD PENINSULA TODAY AND TONIGHT AND ACROSS WEST COAST NORTH
OF THE SEWARD PENINSULA TONIGHT AND SATURDAY. COLDER AIR
CIRCULATING AROUND AN UPPER LOW IN THE BERING SEA WILL PUSH

WINDS WITH SHARP INVERSIONS DEVELOPING IN VALLEYS AFTER SUNSET.
