.DISCUSSION...985 MB LOW IN THE VICINITY OF KISKA AND AMCHITKA
ISLANDS HAS WEAK OCCLUDED FROM ARCING BACK FROM THE CENTER SOUTHEAST
ACROSS THE ADAK/ATKA AREAS WITH LIGHT SNOW AND FOG BUT LITTLE IN THE
WAY OF ANY SIGNIFICANT WIND. LOW TO MOVE EAST TO ADAK BY 9 AM THU.
THE GRAD BETWEEN THIS FEATURE AND THE ARCTIC HIGH OVER THE RUSSIAN
FAR EAST WILL ALLOW THE GUSTY NORTHWEST WINDS NOW PICKING UP AT
SHEMYA TO SLOWLY SPREAD OVER AREA 13 BY LATE THURSDAY AFTERNOON WITH
SNOW SHOWERS FOR AREAS WEST OF ADAK ALONG WITH NNW WINDS 25 TO 35
KTS.

BY THURSDAY AFTERNOON THE LOW WEAKENS A LITTLE AND MOVES TO UNMAK

AFTERNOON. OTHERWISE..ALL OF THE BERING WILL STAY UNDER COOL
NORTHERLY FLOW WITH WINDS UNDER 25 KTS AND WIDESPREAD MVFR.

STORM ROTATES NORTHWARD. STORMS ARE CERTAINLY A POSSIBILITY WITH THIS
FRONT ON SAT FROM KISKA TO ATTKA WITH GALES OVER THE SOUTHERN HALF OF
THE OFFSHORE ZONE. AT THIS POINT IT LOOKS LIKE MAX GALES WILL EXTEND
FROM THE FOX ISLANDS UP TO THE PRIBILOFS WITH STORM EXTENDING FROM
THE CENTRAL BERING SOUTH ACROSS PASY AND ATTU ON SAT NIGHT. THEN THE
FRONT STALLS OUT OVER AREAS 14..8. AND 6A SUN AND SUN NIGHT.
