SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
200 PM AKDT SAT APR 23 2011

.ANALYSIS AND UPPER LEVELS...THE UPPER LEVEL JET REMAINS WELL SOUTH
OF THE FORECAST AREA AS A BROAD TROF DOMINATES THE REGION. THE JET
DIGS SOUTH OUT OF EASTERN SIBERIA BEFORE TURNING EAST TOWARD THE
PACIFIC NORTHWEST. THE MOST DOMINANT FEATURE IS A LARGE STACKED LOW
SOUTH OF THE ALASKA PENINSULA. THE FRONT ASSOCIATED WITH THIS LOW
STRETCHES ACROSS THE NORTHERN GULF...BRINGING STRONG GALE FORCE WINDS
THROUGHOUT MOST OF GULF COASTAL WATERS. A DEFORMATION ZONE EXTENDS
FROM THE BACKSIDE OF THE LOW NORTH THROUGH THE KUSKOKWIM DELTA. RAIN
AND SNOW IS FALLING ACROSS MOST OF THIS AREA. TO THE WEST...BROAD
NORTHERLY FLOW ACROSS THE BERING SEA WITH MARGINAL CEILINGS AND
RAIN/SNOW SHOWERS.

.MODEL DISCUSSION...
MODELS ARE IN EXCELLENT AGREEMENT THROUGH THE SHORT TERM. ONLY MINOR
TWEAKS EXPECTED WITH THE AFTERNOON PACKAGE.

.SHORT TERM FORECAST...
SOUTHCENTRAL...TYPICAL SOUTHEASTERLY FLOW REGIME WITH ABUNDANT
MOISTURE ALONG THE GULF COAST AND DOWNSLOPE CONDITIONS INLAND. THE
FRONT BUTTED UP AGAINST THE NORTH GULF COAST THIS MORNING AND IS
HAVING A HARD TIME MAKING IT ANY FURTHER INLAND AS THE DOWNSTREAM
RIDGE IS PREVENTING ANY MORE FORWARD PROGRESS. THE PARENT LOW NEAR
THE ALASKA PENINSULA WILL WEAKEN THROUGH SUNDAY AS WELL AS THE FRONT
IN THE NORTH GULF COAST. STEADY RAIN WILL DIMINISH IN COVERAGE AND
BECOME SHOWERS BY THE END OF THE WEEKEND. AS THE GRADIENT ALSO
WEAKENS AND MORE HOLES IN THE CLOUDS APPEAR...THE INSTABILITY WILL
INCREASE LEADING TO MORE AFTERNOON SHOWERS EARLY NEXT WEEK. THE WEAK
FLOW ALOFT WILL KEEP MOST OF THE SHOWERS OVER THE MOUNTAINS.

.SOUTHWEST MAINLAND...RAIN AND SNOW WILL DIMINISH AS THE DEFORMATION
ZONE MOVES OVER THE EASTERN BERING SEA. THE LOW SOUTH OF THE ALASKA
PENINSULA WILL MOVE INTO BRISTOL BAY SUNDAY...KEEPING SHOWERS IN THE
REGION THROUGH EARLY NEXT WEEK.

.ALEUTIANS...BROAD NORTHERLY FLOW AND SHOWERS WILL CONTINUE THROUGH
SUNDAY. A WEAK LOW WILL DEVELOP NEAR THE KAMCHATKA PENINSULA TONIGHT
AND DROP SOUTH...CROSSING THE EASTERN ALEUTIANS MONDAY AFTERNOON.
GALE FORCE WINDS WILL FOLLOW THE LOW OVER THE CENTRAL AND WESTERN
ALEUTIANS. THE ACTIVE PATTERN CONTINUES WITH ANOTHER SIGNIFICANT LOW
SPINNING UP OVER THE WESTERN ALEUTIANS MIDWEEK.

.AER/ALU...WATCH/WARNING SUMMARY
.PUBLIC...NONE.
.MARINE...GALES 120 125 129 130 132 138 150 155 165 170 172
          HEAVY FREEZING SPRAY 179 180
.FIRE WEATHER...NONE.
