Small Craft Advisory 334, NWS Anchorage, AK

AREA FORECAST DISCUSSION
SOUTHCENTRAL AND SOUTHWEST ALASKA
500 AM ADT SAT APR 16 2005

.DISCUSSION...A CHANGE IN THE WEATHER PATTERN IN SOUTHERN ALASKA IS
ON THE WAY. A COLD UPPER LEVEL LOW IS DROPPING DOWN OVER THE CHUKCHI
SEA AND WILL MOVE OVER THE MIDDLE OF THE STATE SATURDAY NIGHT AND
SUNDAY. THIS WILL BRING MUCH COLDER TEMPERATURES ALOFT AND COOLER
SURFACE TEMPERATURES SUNDAY THROUGH MONDAY NIGHT. NOT A LOT OF
PRECIPITATION EXPECTED WITH THIS SYSTEM HOWEVER. MOST LIKELY THE ONLY
PRECIPITATION WILL BE OVER MOUNTAINOUS AREAS.

AT THE SURFACE...A 980 MB LOW SOUTH OF AMCHITKA WILL CONTINUE TO MOVE
EASTWARD AND WEAKEN THROUGH EARLY NEXT WEEK. THE HIGH PRESSURE OVER
EASTERN RUSSIA WILL REMAIN IN PLACE THROUGH EARLY NEXT WEEK. THIS
WILL KEEP A TIGHT PRESSURE GRADIENT OVER THE BERING SEA...BUT IT WILL
GRADUALLY DIMINISH.

MODELS STILL IN VERY GOOD AGREEMENT.

.AER/ALU...WATCH/WARNING SUMMARY
PUBLIC...NONE.
MARINE...12A 12B 13A 13B 15.
FIRE WEATHER...NONE.
