A WEAK RIDGE OVER NORTHERN ALASKA WILL BUILD SLOWLY THROUGH TUE AS
A SHORT WAVE TROUGH NOW ALONG THE NORTHERN BERING SEA MAKES ITS
WAY EAST ACROSS NORTHERN ALASKA TO THE ALCAN BORDER BY 4AM WED.
PRECIPITATION WITH THE TROUGH WILL SPREAD NORTHEAST ACROSS THE
STATE BUT DECREASE TUE AS IT MOVES FURTHER EAST AND THE RIDGE
BUILDS. TEMPERATURES WILL COOL SLIGHTLY TUE WITH THE SHORT WAVE.

STARTING WED A RIDGE BUILDS STRONGLY OVER MAINLAND ALASKA WITH A
570 DM HIGH CENTERED OVER INTERIOR ALASKA BY THU. THIS WILL CAUSE
A RAPID WARMING AND DRYING WED THROUGH FRI. EXPECT ABOVE NORMAL
TEMPERATURES THROUGH WED...AND THEN MUCH WARMER CONDITIONS THU
INTO THE WEEKEND.

SURFACE...
A 1030 MB HIGH NORTH OF THE THE ARCTIC COAST OF ALASKA WILL WEAKEN
THROUGH WED. AN ARCTIC COLD FRONT FROM EAGLE TO ATIGUN PASS TO
POINT HOPE WILL MOVE TO THE ARCTIC COAST TONIGHT AND NORTH OF THE
COAST TUE. STRONG EAST WINDS AND BLOWING SNOW ALONG THE COAST
WILL CONTINUE UNTIL THE FRONT MOVES NORTH OF THE COAST EARLY TUE.

A THERMAL TROUGH FROM MCGRATH TO FAIRBANKS TO EAGLE WILL MOVE TO
FAIRBANKS TO EAGLE BY 4PM TUE AND THEN DISSIPATE. WEAK WINDS WILL
BLOW INTO THIS TROUGH. EXPECT WARMEST TEMPERATURES AND DRIEST
CONDITIONS UNDER THIS TROUGH.

A 987 MB LOW NEAR ANADYR WILL MOVE NORTH AND WEAKEN...AND BY 4AM

SNOW CHANGING TO RAIN NEAR THE FRONT WITH RAIN SHOWERS SOUTH OF
