AREA FORECAST DISCUSSION SOUTHCENTRAL ALASKA
500 AM AST MON JAN 3 2005

.DISCUSSION...

AN OMEGA BLOCK HAS SET-UP OVER THE EASTERN PACIFIC...WITH THE RIDGE
AXIS EXTENDING THROUGH THE EASTERN GULF OVER THE AK-YUKON TERRITORY
BORDER. THE TROUGH IN THE CENTRAL BERING COMBINED WITH THE RIDGE
HAS SET UP A SOUTHWEST FLOW FROM THE ALASKA PENINSULA EAST. THE JET
IS DRIVING MOISTURE AND WARM AIR INTO THE WESTERN MAINLAND ZONES AND
SOUTHCENTRAL...PRODUCING SEVERAL INCHES OF SNOW IN THE KUSKOKWIM
VALLEY WITH RAIN AND IN BRISTOL BAY AND FREEZING RAIN ALONG COASTAL
AREAS OF SOUTHCENTRAL AND HEAVY SNOW FOR THE NORTHERN SUSITNA AND
POSSIBLY THE NORTHERN COPPER RIVER BASIN. A STRONG PRESSURE GRADIENT
HAS SET-UP THROUGH SOUTHCENTRAL THIS MORNING WITH THE ADVANCING FRONT
OVER THE ALASKA PENINSULA AND THE PERSISTENT RIDGE OVER THE
PANHANDLE. EAST TO WEST GAPS WINDS SUCH AS TURNAGAIN ARM AND THE
ANCHORAGE HILLSIDE. EAGLE RIVER WINDS ARE GUSTY AS WELL. WINDS WILL
RELAX THIS AFTERNOON AS THE FRONT MOVES OVER SOUTHCENTRAL...AND THE
GRADIENT MOVES EAST.

THE UPPER LEVEL TROUGH WILL PROGRESS SLOWLY EAST TODAY. BY TUESDAY
NIGHT THE BASE OF THE TROUGH WILL MOVE OVER SOUTHCENTRAL...
FLATTENING THE AXIS OF THE RIDGE OVER THE GULF. PRECIPITATION WILL
DIMINISH ON THE BACK SIDE OF THE TROUGH. ON WEDNESDAY MORNING A RIDGE
AXIS OVER THE CENTRAL ALEUTIANS WILL BUILD OVER THE ALASKA PENINSULA.
 THIS WILL BRING A DRIER COLDER NORTHWEST FLOW TO OUR MAINLAND ZONES
WEDNESDAY INTO THURSDAY. THE CENTER OF THE RIDGE WILL THEN BUILD OVER
BRISTOL BAY BY THURSDAY NIGHT. THE CENTER IS THEN PROJECTED TO MOVE
OVER SOUTHCENTRAL BY NEXT WEEKEND. WE ARE STILL LOOKING FOR THE
POSSIBILITY OF A PROLONGED PERIOD OF FOG FOR MAINLAND ALASKA AND
SOUTHCENTRAL AT THE END OF THE WORKWEEK THROUGH THE WEEKEND.
