NWS Anchorage, AK wrote its last area forecast discussion before this brisk wind advisory went out at Apr 30, 1:00 PM AKDT, 3 hours earlier.

SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
100 PM AKDT MON APR 30 2012

.MODEL DISCUSSION...MODELS ARE IN GOOD AGREEMENT IN THE SHORT-TERM.
LOW IN THE NORTHERN GULF CONTINUES TO SLIDE TO THE SOUTHEAST AND
WEAKEN OVER THE NEXT 24 HOURS. A NEW LOW FORMS NEAR PWS TUE IN
RESPONSE TO COLD AIR MOVING DOWN FROM THE NORTHWEST.  THIS UPPER
LEVEL TROUGH IN THE NORTHWEST IS PROGED TO REMAIN WELL TO OUR NORTH
BUT LOW-LEVEL COLD AIR SHOULD START TO MOVE INTO THE UPPER KUSKO AND
SUSITNA VALLEY EARLY TUE MORNING. THIS COOLER AIR MAY GENERATE SOME
SNOW AND RAIN SHOWERS TUE MORNING BUT MAINLY AT HIGHER ELEVATIONS.

HIGH PRESSURE PERSISTS OVER THE ALEUTIANS AND SOUTHERN BERING THROUGH
THE FORECAST PERIOD. SOME MODEL DISAGREEMENT STARTING AROUND LATE
WED. GRIDDED FORECAST IN THE WEST FROM WED ONWARD BASED ON GFS
SOLUTION.

.ANALYSIS AND UPPER LEVELS...CURRENTLY THE RIDGE OF HIGH PRESSURE
OVER THE BERING IN CONJUNCTION WITH A LOW IN THE NORTHWEST IS
PRODUCING A MODERATE PRESSURE GRADIENT OVER BRISTOL BAY AND THE AK
PEN TODAY. THIS SHOULD CONTINUE ON TUE BUT RELAX ON WED.  COLD AIR
MOVING INTO THE REGION WILL GENERATE MODERATE TO STRONG GAP WINDS TUE
AND WED.

.SHORT TERM FORECAST...
BERING REGION...LOW CLOUDS WILL PREVAIL. A WEAK FRONT MOVES THROUGH
THE WESTERN ALEUTIANS TUE AFTERNOON.

SOUTHWEST...CONTINUED NORTH WINDS WITH LOW CLOUDS AND FLURRIES MAINLY
ALONG THE COAST BUT INLAND FOR ZONE 155 AS WELL. NEXT CHANCE OF SNOW
OR RAIN IS TUE NIGHT.

SOUTHCENTRAL...INCREASING CLOUDS OVER SUSITNA AND COOK INLET TONIGHT
WITH TEMPERATURES DECREASING THROUGH THE DAY ON TUE.  CHANCE OF SNOW
OR RAIN TUE MORNING MAINLY OVER THE MOUNTAINS...CLEARING LATER ON
TUE. MODERATE TO STRONG NORTHERLY WINDS IN GAP AREAS THROUGH WED
MORNING.

.LONG TERM FORECAST...DESPITE SOME DISCREPANCY FROM MODEL TO MODEL
THE GENERAL TREND IS FOR A LOW TO MOVE INTO THE EASTERN BERING THU
AND SLIDE OVER KODIAK ISLAND FRI.  WILL PROBABLY SEE RAIN OVER MOST
OF SOUTHWEST ZONES THU AND FRI AND IN SOUTHCENTRAL ON FRI AND SAT. IN
SOME INLAND AREAS RAIN COULD BE MIXED WITH SNOW.
