SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
400 PM AKDT MON APR 23 2012

.ANALYSIS AND UPPER LEVELS...WEAK UPPER LEVEL FLOW RESIDES OVER THE
MAINLAND PART OF THE STATE WITH A CLOSED UPPER LEVEL LOW IN THE
EASTERN BERING SEA. WEST OF THIS LOW THERE IS ZONAL UPPER LEVEL FLOW
OVER THE REMAINDER OF THE BERING SEA...WHICH WILL AMPLIFY OVER THE
NEXT DAY INTO AN UPPER LEVEL RIDGE OVER THE WESTERN ALASKA COAST. THE
LOW CURRENTLY IN THE EASTERN BERING WILL MOVE SOUTHEAST AND LIE JUST
SOUTH OF THE GULF OF ALASKA BY TUESDAY AFTERNOON.
AT THE SURFACE THERE IS GENERALLY HIGH PRESSURE OVER THE INTERIOR OF
THE STATE WITH THE MAIN LOW A LITTLE EAST OF DUTCH HARBOR. IN BETWEEN
THESE FEATURES THERE IS A FRONTAL BOUNDARY THROUGH THE WESTERN GULF
AND OVER KODIAK ISLAND THAT EXTENDS THROUGH THE BRISTOL BAY REGION
AND INTO THE KUSKOKWIM DELTA.

.MODEL DISCUSSION...MODELS CONTINUE TO DO VERY WELL. THERE ARE NO
MAJOR CONCERNS FOR ANYTHING AFFECTING THE FORECAST AREA.

.SHORT TERM FORECAST...MOSTLY CLEAR SKIES ARE OVER SOUTH CENTRAL
ALASKA AND THE COPPER RIVER BASIN. THERE IS AN EASTERLY WAVE THAT
SHOULD MOVE INTO THE EASTERN COPPER RIVER BASIN OVERNIGHT AND WEAKEN
AS IT MOVES WESTWARD TOMORROW. THIS WILL PRODUCE SOME SCATTERED RAIN
AND SNOW SHOWERS IN THE BASIN LATE TONIGHT AND A FEW RAIN SHOWERS
TOMORROW. IT SHOULD WEAKEN SUFFICIENTLY AS IT MOVES WESTWARD THAT IT
WILL NOT PRODUCE MORE THAN MID TO HIGH LEVEL CLOUDS ONCE IT CROSSES
THE CHUGACH MOUNTAINS.
THE FRONT FROM KODIAK THROUGH BRISTOL BAY HAS REACHED ITS FARTHEST
FORWARD PROGRESSION AND WILL BEING TO RECEDE TO THE SOUTH AS THE LOW
UNDERCUTS THE AREA AND THE UPPER LEVEL RIDGE BUILDS INTO WESTERN
ALASKA TONIGHT INTO TOMORROW.
A RAIN AND SNOW SHOWER MIX WILL DIMINISH THIS EVENING IN THE EASTERN
ALEUTIANS AND LINGER INTO TOMORROW MORNING OVER THE ALASKA PENINSULA.

.LONG TERM FORECAST...HIGH PRESSURE WILL STRENGTHEN OVER THE MAINLAND
OF THE STATE BY MIDWEEK AND KEEP SKIES GENERALLY PARTLY CLOUDY TO
MOSTLY SUNNY WEDNESDAY THROUGH FRIDAY OVER THE MAINLAND. EVEN KODIAK
ISLAND WILL SEE A BREAK IN THE CLOUDS DURING THE MIDDLE TO LATER PART
OF THE WEEK.
THERE WILL BE A WEAK LOW MOVING THROUGH THE ALEUTIANS THAT WILL BRING
SOME SHOWERS THERE THROUGH THE PERIOD..
