SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
500 AM AKDT MON AUG 15 2011

.ANALYSIS AND UPPER LEVELS...
THE UPPER LOW RESPONSIBLE FOR UNSETTLED WEATHER TODAY CONTINUES TO
DROP SOUTH INTO THE GULF OF ALASKA. A BROAD TROUGH REMAINS IN ITS
WAKE OVER MUCH OF THE STATE. ANOTHER UPPER LOW SPINS JUST SOUTH OF
THE WESTERN ALEUTIANS. BETWEEN THESE TWO FEATURE THE UPPER RIDGE THAT
HAD BEEN ANCHORED OVER THE CENTRAL ALEUTIANS IS BEING PUSHED INTO THE
NORTHERN PACIFIC.

AT THE SURFACE...A BROAD AREA OF LOW PRESSURE STRETCHES ACROSS MOST
OF ALASKA CENTERED FROM THE COPPER RIVER BASIN TO THE GULF OF ALASKA
UNDERNEATH THE UPPER LOW. ANOTHER SURFACE LOW ROTATES JUST SOUTH OF
THE WESTERN ALEUTIANS. WEAK SURFACE RIDGING LIES BETWEEN THE TWO
SURFACE LOWS AROUND THE CENTRAL/EASTERN ALEUTIANS.

.MODEL DISCUSSION...
FOR THE SHORT TERM MODELS IN GOOD AGREEMENT WITH THE UPPER LEVEL
FEATURES. THE GULF OF ALASKA LOW WILL ROTATE ONSHORE ALONG THE ALASKA
PANHANDLE WHILE A WEAKER DISTURBANCE ROTATES THROUGH THE ALASKA
LONGWAVE TROUGH OVER THE WESTERN PORTION OF THE STATE TUESDAY INTO
WEDNESDAY. AT THIS JUNCTURE THE MODEL SOLUTIONS START TO DIVERGE IN
THE HOW ENERGY SPINNING OFF A SHORTWAVE NEAR THE KAMCHATKA PENINSULA.
THE ONE FEATURE THE MODELS CAN AGREE ON FOR THE MID WEEK TIME PERIOD
IS A FASTER ZONAL FLOW CENTERED OVER THE ALEUTIAN CHAIN AS WELL AS
THE DEVELOPMENT OF A MODERATELY STRONG SURFACE LOW MOVING INTO THE
BRISTOL BAY REGION BY LATE WEEK.

.SHORT TERM FORECAST...
SOUTHCENTRAL ALASKA...SHOWERS WILL BE ON THE DECREASE FOR THE MORNING
FOR MOST OF THE MAINLAND WHILE RAIN SHOWERS WILL STAY NUMEROUS IN THE
GULF OF ALASKA AS THE UPPER TROUGH MOVES OUT. DURING THE AFTERNOON
SHOWER COVERAGE WILL REMAIN SCATTERED WITH THE CHANCE FOR AN ISOLATED
THUNDERSTORM MAINLY OVER INTERIOR AREAS.

SOUTHWEST ALASKA...WHILE SOME BREAKS IN THE CLOUDS MAY APPEAR IN
COASTAL REGIONS TODAY SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS
WILL MOVE BACK IN TO THE KUSKOKWIM VALLEY AND EASTERN BRISTOL BAY
REGIONS. THE COLD UPPER LOW COMBINED WITH SURFACE HEATING WILL
PROMOTE INSTABILITY LEADING TO THUNDERSTORMS. WHILE THE PRECIPITATION
WILL TAPER OFF OVERNIGHT MORE SHOWERS AND THUNDERSTORMS WILL RETURN
TO THE SOUTHWEST INTERIOR ON TUESDAY.

BERING SEA AND ALEUTIANS...SCATTERED SHOWERS WILL STAY IN THE
FORECAST FOR THE WESTERN THROUGH THE CENTRAL AND EASTERN ALEUTIANS
TODAY. MORE WIDESPREAD STEADY RAIN WILL EXIST IN THE MARINE ZONES
NORTH OF THE CHAIN AS A WARM FRONTAL BOUNDARY WILL REMAIN DRAPED OVER
THE AREA. THE RESPONSIBLE LOW PRESSURE SYSTEM WILL DRIFT EASTWARD ON
TUESDAY SPREADING SHOWERS TO THE CENTRAL AND EASTERN ALEUTIANS.

.LONG TERM FORECAST...
A PIECE OF SHORTWAVE ENERGY WILL SPIN OFF THE CLOSED LOW OVER
KAMCHATKA MID WEEK AND DEVELOP A MODEST LOW PRESSURE SYSTEM JUST
NORTH OF THE ALEUTIAN CHAIN. TIMING IS NOT CERTAIN AS OF YET BUT
WIDESPREAD RAIN AND GUSTY WINDS TO THE BERING. DEPENDING ON THE EXACT
TRACK THIS SYSTEM WILL AFFECT SOUTHERN ALASKA BY THE WEEKEND.
