.DISCUSSION...
NOT MUCH CHANGE IN THE WEATHER PATTERN OVER SOUTHERN ALASKA TODAY.
JET STREAM WELL SOUTH OF THE AREA AND IS TAKING THE STORM SYSTEMS
SOUTH AS WELL. THERE IS A LOW SOUTH OF THE GULF OF ALASKA THAT WILL
MOVE TOWARD THE PANHANDLE TONIGHT...BUT IT WILL RUN INTO THE
PERSISTING HIGH PRESSURE OVER THE MAINLAND PART OF THE STATE AND THEN
DRIFT SOUTHWARD AND WEAKEN OVER THE WEEKEND.

A MODERATE LOW SOUTH OF ATTU WILL SLOWLY MOVE EAST THROUGH THE
WEEKEND. THE MAIN IMPACT OF THIS LOW WILL BE IN THE BERING SEA AND
THE ALEUTIAN ISLANDS. THIS LOW...COMBINED WITH A 1040 MB HIGH IN THE
ARCTIC OCEAN...WILL CREATE A RATHER TIGHT PRESSURE GRADIENT OVER THE
BERING SEA AND ALEUTIAN CHAIN. THIS WILL BRING GALE FORCE WINDS IN
THESE AREAS AS THE LOW PASSES SOUTH OF THEM.

GFS...ETA...UKMET...ECMF MODELS ALL IN GOOD GENERAL AGREEMENT.
