AREA FORECAST DISCUSSION
SOUTHCENTRAL AND SOUTHWEST ALASKA
200 PM AST SAT NOV 5 2005

.DISCUSSION...BIGGEST WEATHER ISSUE TODAY CONTINUES TO BE STRONG
OUTFLOW WINDS ALONG THE NORTH GULF COAST. WINDS TO 70 MPH IN THE
VALDEZ AREA WILL DIMINISH THIS EVENING AS THE LOW SOUTH OF YAKUTAT
WEAKENS AND MOVES TOWARD THE QUEEN CHARLOTTE ISLANDS. STRONG WINDS IN
THE KODIAK AREA WILL ALSO DIMINISH BY THIS EVENING FOR THE SAME
REASON.

THE 250 MB JET STREAM CONTINUES TO BE MOSTLY SOUTH OF THE FORECAST
AREA WITH A COLD UPPER LEVEL TROUGH OVER THE CENTRAL PART OF THE
STATE. AN UPCOMING CHANGE TO THIS IS THAT A JET COUPLET WILL DEVELOP
TONIGHT THAT STRETCHES FROM EASTERN RUSSIA TO THE SOUTHWEST GULF OF
ALASKA. IN ASSOCIATION WITH THIS JET STREAK IS WILL BE A FAST MOVING
SURFACE LOW THAT WILL MOVE ACROSS THE SOUTHWEST PORTION OF THE
MAINLAND TONIGHT AND INTO THE NORTHERN GULF OF ALASKA SUNDAY MORNING.

THIS RAPIDLY MOVING SYSTEM WILL BRING SNOW INTO THE SOUTHWESTERN
PORTIONS OF MAINLAND ALASKA TONIGHT AND INTO THE KENAI PENINSULA BY
EARLY SUNDAY MORNING.

THE OTHER BIG ITEM OF INTEREST WITH THIS SYSTEM IS THAT ONCE IT MOVES
INTO THE GULF OF ALASKA IT WILL INTENSIFY AND BRING STRONG WINDS INTO
THE NORTH GULF COAST AND KODIAK ISLANDS AREAS SUNDAY.

A 995 MB LOW SOUTHWEST OF ATTU WILL MOVE SOUTH OF ATTU AND STRENGTHEN
TO AROUND 988 MB SUNDAY AFTERNOON. THIS LOW WILL THEN STRENGTHEN SOME
MORE TO AROUND 978 MB MONDAY AFTERNOON. EXPECT STORM AND GALE FORCE
WINDS TO COVER MOST OF THE BERING SEA MONDAY WITH THIS SYSTEM.
