THE BROOKS RANGE. TEMPERATURES WILL COOL TO -30C OVER THE EASTERN
INTERIOR TODAY WITH LITTLE CHANGE REMAINDER OF NORTHERN ALASKA.
MON WILL SEE SLIGHT WARMING INTERIOR AND WEST COAST BUT EXPECT NO
WARMING AT THE SURFACE DUE TO CLEAR CONDITIONS.

SURFACE...
AN ARCTIC COLD FRONT STRETCHING FROM MENTASTA PASS TO MAYO WILL
MOVE EAST TODAY. A 990 MB LOW IN THE SOUTHERN YUKON WILL REMAIN IN
PLACE TODAY THEN MOVE SLOWLY EAST TONIGHT. THIS LOW IS PUSHING
MOISTURE BACK OVER THE ARCTIC FRONT CAUSING SNOW IN THE EASTERN

TROUGH ALOFT.

A 1024 MB HIGH OVER THE CHUKCHI SEA WILL BUILDING EAST OVER

MODELS SIMILAR SOLUTIONS THROUGH 3PM SUN...THEN THE NAM WEAKENS
THE LOW IN THE SOUTHERN YUKON MUCH MORE RAPIDLY THAN THE GFS AND
