AND INTO THE GULF OF ALASKA SET UP A CONSTANT STREAM OF NORTHEASTERLY WINDS AND
SOME SIGNIFICANT SNOWFALL FOR THE FIRST TWO-THIRDS OF FEBRUARY. LATER IN THE
MONTH...PREDOMINANT WINDS SHIFTED TO THE SOUTH AS HIGH PRESSURE BUILT OVER MAINLAND
ALASKA...WHILE LOW PRESSURE SET UP IN THE FAR WESTERN ALEUTIANS. THIS CREATED ABOVE
NORMAL TEMPERATURES...AND A CHANGE OVER TO RAIN THROUGH THE REST OF FEBRUARY.

TEMPERATURES...WHILE BREAKING A THIRD.

PRECIPITATION WAS SLIGHTLY BELOW NORMAL...WHILE SNOWFALL WAS VERY SLIGHTLY ABOVE
NORMAL. AS ONE NEW DAILY SNOWFALL RECORD WAS BROKEN DURING THE MONTH...NEITHER
LIQUID PRECIPITATION NOR SNOWFALL FOR THE MONTH WAS EVEN IN THE TOP TWENTY-FIVE
WETTEST OR DRIEST FOR FEBRUARY.
