SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
200 PM AKDT THU JUNE 2 2011

.ANALYSIS AND UPPER LEVELS...
LONG WAVE PATTERN REMAINS UNCHANGED WITH A LARGE UPPER TROF
POSITIONED OVER THE CENTRAL BERING SEA. A 976 MB LOW HAS REACHED ITS
PEAK STRENGTH THIS MORNING AS IT CROSSED THE CENTRAL ALEUTIANS. THE
ASSOCIATED FRONTAL BOUNDARY IS RACING EAST ACROSS THE ALASKA
PENINSULA...SPREADING NEAR WARNING LEVEL WINDS TO THE REGION. HIGH
PRESSURE UPSTREAM OF THIS FEATURE IS WILL QUICKLY BE PUSHED ASIDE AS
THE FRONT APPROACHES THE SOUTHWEST MAINLAND THIS EVENING AND
SOUTNCENTRAL ALASKA TOMORROW.

.SHORT TERM FORECAST...MAIN FORECAST ISSUES ARE REGARDING THE FRONTAL
BOUNDARY MOVING FROM THE ALASKA PENINSULA TOWARD THE NORTHWESTERN
GULF TONIGHT. THE TROPICAL ORIGINS OF THIS STORM IS EVIDENT WITH
GREATER THAN 200 PERCENT OF THE TOTAL PRECIPITAL WATER ALONG THE
PENINSULA. COLD BAY HAS BEEN REPORTING HEAVY RAIN FOR SEVERAL HOURS
NOW AS THE FRONT NEARS. THIS TROPICAL FETCH WILL BE PINCHED OFF BY A
DEVELOPING OCCLUDED LOW TONIGHT JUST SOUTH OF KODIAK ISLAND.
STILL...EXPECTING RAIN TO SPREAD NORTH AND EAST OVERNIGHT AND IMPACT
SOUTHCENTRAL BY LATE FRIDAY AFTERNOON.

BESIDES THE MOISTURE...THE OTHER IMPACT WITH THIS SYSTEM IS THE WIND.
WINDS ARE FLIRTING WITH WARNING CRITERIA ALONG THE ALASKA PENINSULA.
CHANNELED TERRAIN ALONG THE ALASKA RANGE WILL EXPERIENCE VERY GUSTY
CONDITIONS OVERNIGHT. THE PRESSURE GRADIENT WILL RAPIDLY TIGHTEN OVER
SOUTHCENTRAL RESULTING IN STRONG WINDS THROUGH TURNAGAIN ARM AND
PORTAGE VALLEY. THE DOWNSLOPING WILL NOT BE ENOUGH TO PREVENT RAIN
FROM FALLING ON THE LEE SIDE OF THE RANGE.

THE LOW IN THE BERING VERY SLOWLY WEAKENS AND MEANDERS NORTH AND WEST
THROUGH THE REST OF THE WEEKEND. UPPER LEVEL WAVES EMBEDDED IN THE
SOUTHWEST FLOW WILL KEEP CLOUDS AND MOISTURE ACROSS SOUTHWEST AND
SOUTHCENTRAL ALASKA THROUGH THE WEEKEND...RESULTING IN MOSTLY CLOUDY
SKIES AND SCATTERED SHOWERS. NOT UNTIL MONDAY WILL HIGH PRESSURE
BUILD BACK OVER THE REGION AS THE NEXT NPAC LOW DEVELOPS SOUTH OF THE
CHAIN AND FOLLOWS A SIMILAR PATCH AS THE PREVIOUS STORMS MIDWEEK.
