.DISCUSSION...
A STRONG PUSH OF WARM AIR INTO SOUTHERN ALASKA CONTINUES TODAY.
ALMOST ALL AREAS HAVE NOW HAD THEIR SNOW TURN TO RAIN WITH STIFF
SOUTHERLY WINDS. THE WINDS HAVE ALSO BROKEN THE INVERSIONS IN THE
KUSKOKWIM DELTA AND VALLEY AND HAVE ENDED THE FREEZING RAIN IN THOSE
AREAS AS WELL. PRECIPITATION TYPES SHOULD BEGIN TO TURN BACK TO SNOW
BEGINNING IN THE KUSKOKWIM VALLEY AND DELTA TONIGHT...MOVING INTO
BRISTOL BAY FRIDAY EVENING...AND THEN INTO AREAS EAST OF THE ALASKA
RANGE AFTER THAT.

IN THE UPPER LEVELS...A LOW OVER BRISTOL BAY WILL WEAKEN THROUGH
FRIDAY MORNING AS IT MOVES NORTH OF THE SEWARD PENINSULA. COLDER AIR
WEST OF THIS LOW WILL SLOWLY MOVE INTO THE AREA AS IT MOVES
NORTHWARD.
NEXT SIGNIFICANT SYSTEM IS CURRENTLY NEAR 43N 160W AND HEADING TOWARD
THE GULF OF ALASKA. THIS SYSTEM SHOULD MOVE INTO THE WEST CENTRAL
GULF FRIDAY AFTERNOON AROUND 980 MB AND WEAKEN AS IT MOVES TO PRINCE
WILLIAM SOUND FRIDAY NIGHT. SECONDARY LOW WILL DEVELOP JUST SOUTHWEST
OF KODIAK ISLAND SATURDAY MORNING AND MOVE INTO COOK INLET BY SUNDAY.
THESE TWO SYSTEMS WILL HAVE ENTRAINED ENOUGH COLD AIR INTO THEM TO
