AREA FORECAST DISCUSSION
SOUTHCENTRAL AND SOUTHWEST ALASKA
500 AM AST SAT FEB 24 2007

.DISCUSSION...
CURRENTLY...A SHORT WAVE ALOFT FROM AN UPPER LOW OVER THE BEAUFORT
SEA IS MOVING SOUTH OVER THE ALASKA RANGE AND INTO THE GULF. AN UPPER
LEVEL HIGH IS STRENGTHENING OVER THE WESTERN ALEUTIANS RESULTING IN
INCREASING NORTHWESTERLY FLOW ALOFT OVER THE EASTERN ALEUTIANS AND
THE AKPEN. THE ASSOCIATED SURFACE LOW OVER THE CENTRAL ALEUTIANS IS
STRENGTHENING AS WELL AND SLOWLY MOVING EAST. A SURFACE HIGH OVER THE

CENTRAL INTERIOR AND A TROUGH OF LOW PRESSURE OVER THE GULF CONTINUES
TO CREATE GUSTY GAP WINDS OVER SOUTHCENTRAL MAINLAND. LIGHT SNOW
SHOWERS CONTINUE OVER THE KUSKOKWIM DELTA FROM A DISSIPATED LOW THAT
CAME ASHORE OVER NIGHT. SNOW SHOWERS CONTINUE OVER THE EASTERN BERING
AND AKPEN IN THE NORTHWEST FLOW.

MODELS DID VERY WELL IN BOTH AGREEMENT AND IN CONSISTENCY OVER THE
SHORT AND LONG TERM.

EAST DOMAIN...PRESSURE GRADIENT BETWEEN THE INTERIOR HIGH AND THE
GULF LOW WILL TIGHTEN THROUGHOUT THE DAY AND REACH ITS MAX TONIGHT
AND EARLY SUNDAY MORNING. WITH THE COMBINATION OF THE SHORT WAVE
ALOFT PASSING OVER SOUTHCENTRAL DURING THE SAME TIME FRAME...EXPECT A
RETURN OF STRONG NORTHERLY WINDS. HAVE BUMPED UP THE HIGH WIND WATCH
TO A HIGH WIND WARNING FOR COPPER RIVER DELTA AND VALDEZ INCLUDING
THOMPSON PASS TO REFLECT THIS. WIND CHILL ADVISORIES ARE IN EFFECT
FOR THOMPSON PASS...COPPER RIVER DELTA AND SUSITNA VALLEYS WITH COLD
AND WINDY CONDITIONS COMBINING. THE UPPER LEVEL LOW NORTH OF ALASKA
WILL REMAIN NEARLY STATIONARY THROUGH THE MIDDLE OF NEXT WEEK WITH
THE UPPER LEVEL BERING RIDGE TO MOVE SLIGHTLY EAST. THIS WILL KEEP
CONTINUED COLD AND MOSTLY CLEAR CONDITIONS TO PERSIST THROUGH NEXT
WEEK.

WEST DOMAIN...SNOW SHOWERS WILL DISSIPATE TODAY OVER SOUTHWESTERN
MAINLAND BEFORE A TROUGH MOVES ONSHORE SUNDAY TO BRING ANOTHER ROUND
OF INCREASED CLOUDS AND SNOW...ONLY TO CLEAR OUT AGAIN MONDAY. THE
HIGH OVER THE WESTERN ALEUTIANS WILL MOVE SLOWLY EAST REACHING THE
AKPEN BY MONDAY. PUSHING THE HIGH EAST IS A NORTH PACIFIC LOW WHICH
WILL BRING WARM ENOUGH TEMPERATURES TO TURN MOST PRECIPITATION TO
RAIN OVER THE WESTERN CENTRAL AND EASTERN ALEUTIANS THROUGH THE FIRST
HALF OF NEXT WEEK.
