SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
500 PM AKDT SAT JUL 16 2011

.MODEL DISCUSSION...MODELS ARE IN GENERALLY GOOD AGREEMENT. THE GFS
PROGRESSES A LOW ACROSS THE ALEUTIANS MONDAY NIGHT SLIGHTLY FASTER
THAN THE NAM AND EC. NAM EC SOLUTION HAS BETTER RUN TO RUN
CONSISTENCY AS WAS PREFERRED THROUGH THE SHORT TERM. CONSISTENCY IS
LACKING IN THE LONG TERM LOWERING CONFIDENCE IN ANY ONE
SOLUTION...LEANED TOWARDS HPC GUIDANCE IN THE EXTENDED.

.ANALYSIS AND UPPER LEVELS...COLD UPPER LEVEL LOW CENTERED OVER THE
SEWARD PENINSULA REMAINS RELATIVELY STATIONARY THROUGH SUNDAY THEN
BEGINS TO SLOWLY TRACK SOUTHEASTWARD ACROSS THE STATE...MOVING INTO
THE GULF BY TUESDAY MORNING. STACKED LOW NORTHEAST OF SHEMYA WILL
MOVE EASTERLY ACROSS THE BERING DRAGGING A FRONT ACROSS THE ALEUTIANS
IN THE PROCESS. FOLLOWING THIS LOW...HIGH PRESSURE WILL BUILD IN OVER
THE ALEUTIANS SUNDAY NIGHT. THE RIDGE WILL QUICKLY MOVE TO THE EAST
AND BE OVER THE GULF AND SOUTHCENTRAL BY WEDNESDAY MORNING.

.SHORT TERM FORECAST...

FOR THE EAST...COLD ADVECTION IN THE UPPER LEVELS WILL INCREASE
AIRMASS INSTABILITY ACROSS SOUTHCENTRAL ALASKA. THERE WILL BE A
CHANCE FOR RAIN SHOWERS PRIMARILY IN THE MOUNTAINS AND A CHANCE FOR
ISOLATED THUNDERSTORMS IN THE SUSITNA AND MATANUSKA VALLEYS AND THE
COPPER RIVER BASIN BOTH TODAY AND TOMORROW. SHORT WAVE TROUGHS
EMBEDDED IN THE CYCLONIC UPPER LEVEL FLOW WILL ENHANCE SHOWER
ACTIVITY...FIRST WAVE PASSES OVER THE AREA THIS AFTERNOON...SECOND
ARRIVES EARLY TOMORROW EVENING.

.FOR THE WEST...SOUTHWEST MAINLAND ALASKA WILL BE PRIMARILY RAIN FREE
FOR TODAY UNTIL THE NEXT SHORT WAVE MOVES IN FROM THE LATE TONIGHT.
RAIN SHOWERS WILL BEGIN OVERNIGHT AND CONTINUE THROUGH MONDAY.
FURTHER WEST...AS THE LOW IN THE SOUTHWESTERN BERING AND ITS
ASSOCIATED FRONT CONTINUE TO TRACK EAST RAIN SHOWERS WILL BE SEEN
THROUGHOUT THE ALEUTIANS. HIGH PRESSURE FOLLOWING THIS LOW WILL CAUSE
FOG TO BECOME THE PRIMARY CONCERN FOR THE ALEUTIANS.

.LONG TERM FORECAST...THE NORTH PACIFIC HIGH WILL CONTINUE TO BE A
DOMINANT FEATURE AND THIS WILL HELP TO KEEP FLOW OVER THE STATE ZONAL
BRINGING AN ACTIVE WEATHER PATTERN ACROSS THE BERING INTO MAINLAND
ALASKA.

.AER/ALU...WATCH/WARNING SUMMARY
PUBLIC...NONE.
MARINE...NONE.
FIRE WEATHER...NONE.
