AREA FORECAST DISCUSSION
SOUTHCENTRAL AND SOUTHWEST ALASKA
500 AM AST FRI MAR 9 2007

.DISCUSSION...
HIGHLY AMPLIFIED PATTERN WITH A SHARP RIDGE OVER THE WESTERN BERING
SEA AND A DEEP CLOSED LOW OVER THE NORTHERN GULF. ARCTIC AIR PUSHING
SOUTH OVER THE BERING SEA AND WESTERN ALASKA CREATING DANGEROUS LATE
WINTER WEATHER. BITTER WIND CHILLS AND BLIZZARD CONDITIONS COVER
MUCH OF SOUTHERN ALASKA AND THE ALEUTIANS/BERING SEA. THE SOURCE
OF THE COLD AIR IS FROM SIBERIA AND THERE IS EVEN SOME CROSS POLAR
FLOW. TEMPERATURES RANGE ANYWHERE FROM 15 TO 30 DEGREES BELOW NORMAL
ACROSS THE AREA. WINDS ARE EXPECTED TO SLOWLY EASE UP OVER THE
EASTERN BERING SEA TODAY WITH BLIZZARD CONDITIONS ABATING.

MODEL GUIDANCE SUGGESTS THE BASIC PATTERN WILL REMAIN IN PLACE FOR
THE NEXT TWO WEEKS OR EVEN LONGER. POLAR AIR OF VERY HIGH LATITUDE
ORIGIN WILL CONTINUE KEEPING TEMPERATURES WELL BELOW NORMAL.
