AREA FORECAST DISCUSSION
SOUTHCENTRAL AND SOUTHWEST ALASKA
120 PM AKDT SUN MAY 16 2010

.ANALYSIS AND UPPER LEVELS...AN UPPER TROUGH IS CENTERED OVER THE
EASTERN BERING AND FAR NORTH CENTRAL PACIFIC WITH TWO EMBEDDED
CLOSED LOWS OVER THE BERING AND ONE SOUTH OF THE ALASKA PENINSULA.
THE LOW OVER THE NORTH CENTRAL BERING APPEARS IN SATELLITE IMAGERY
TO HAVE A SURFACE CIRCULATION...WHICH NONE OF THE MODELS PICK UP ON.
THIS IS SUPPORTED BY OBSERVATIONS FROM BUOY 46035 ON THE WEST SIDE
OF THE LOW WHERE WINDS ARE GUSTING TO 33 KT. IN ANY CASE...THE
BERING LOWS WILL EVENTUALLY BE ABSORBED BY THE MUCH STRONGER
VERTICALLY STACKED LOW SOUTH OF THE ALASKA PENINSULA...WHICH HAS
DEEPENED THE PAST 24 HOURS LARGELY DUE TO FORCING FROM A 170 KT
JET JUST TO ITS SOUTH. THE ZONAL CONFIGURATION OF THE JET IS
HELPING TO ELONGATE THE UPPER TROUGH EASTWARD TOWARD THE NORTHWEST
U.S....BUT THE LOW IS CUT OFF FROM THIS FLOW AND IS NEARLY
STATIONARY. RAIN AND STRONG WINDS DOMINATE KODIAK ISLAND/ALASKA
PENINSULA/EASTERN ALEUTIANS WHILE SNOW IS FALLING BACK OVER THE
PRIBILOF ISLANDS ALONG A TROUGH AXIS THAT EXTENDS FROM THE LOW
CENTER NORTHWESTWARD ACROSS THE BERING SEA. STRONG EASTERLY FLOW
ACROSS THE ALEUTIAN RANGE IS RESULTING IN DOWNSLOPE DRYING FOR
MUCH OF BRISTOL BAY WHILE THE REST OF THE SOUTHERN MAINLAND IS
OBSERVING ISOLATED TO SCATTERED SHOWERS DUE TO WEAK WAVES EMBEDDED
IN THE CYCLONIC FLOW AROUND THE MAIN LOW.

.MODEL DISCUSSION...WITH THE EXCEPTION OF THE LOW OVER THE NORTH
CENTRAL BERING MODELS ARE ALL IN GOOD AGREEMENT WITH HANDLING
OF THE LOW SOUTH OF THE ALASKA PENINSULA THE NEXT FEW DAYS AND
SHOW GOOD RUN-TO-RUN CONSISTENCY. DIFFERENCES DO ARISE WITH THE
STRENGTH AND POSITION OF UPPER WAVES TRACKING ACROSS THE GULF AND
SOUTHERN MAINLAND BEGINNING MONDAY NIGHT AS WELL AS WITH TRACK OF
A WEAK SURFACE LOW INTO THE EASTERN GULF TUE. THIS MAKES IT A
DIFFICULT FORECAST MID WEEK BECAUSE THESE WAVES HAVE THE POTENTIAL
FOR PRODUCING STEADY RAIN WITH COOL TEMPERATURES. FOR NOW WILL
MAKE LITTLE CHANGE AND BE CONSERVATIVE WITH THE PROBABILITY OF
PRECIPITATION FORECAST.

.SHORT TERM FORECAST...THE LOW SOUTH OF THE ALASKA PENINSULA WILL
WOBBLE AROUND THROUGH MONDAY NIGHT AND THEN FINALLY BEGIN TO MOVE
OFF TO THE SOUTHEAST ON TUESDAY AS ENERGY ROTATES OUT OF ASIA AND
FORCES PROGRESSION OF THE HEMISPHERIC WAVES. UNTIL THEN STEADY
RAIN WILL CONTINUE OVER KODIAK ISLAND AND ALONG THE SOUTH SIDE OF
THE ALASKA PENINSULA. RAIN AND SNOW WILL ALSO PERSIST ALONG THE
TROUGH AXIS OVER THE BERING SEA WHICH WILL ROTATE SOUTHWARD ACROSS
THE ALEUTIANS ON MONDAY. MEANWHILE...LOTS OF SUNSHINE OVER INTERIOR
ALASKA WILL HEAT THINGS UP MONDAY THROUGH WEDNESDAY. THIS WILL SET
UP THE MOST WELL DEFINED THERMAL TROUGH SO FAR THIS SEASON ALONG
THE ALASKA RANGE ON TUESDAY AFTERNOON AND EVENING...AND EXTENDING
INTO SOUTHWEST ALASKA ON WEDNESDAY. THIS WILL TRIGGER DIURNAL
CONVECTION OVER INLAND AREAS WHILE UPPER WAVES WILL RESULT
IN AREAS OF RAIN OVER THE SOUTHERN MAINLAND. UNCERTAINTY IN THE
TRACK OF THESE UPPER WAVES IS VERY HIGH...SO FORECAST CONFIDENCE
IS LOW. OUT WEST...HIGH PRESSURE WILL BUILD OVER THE WESTERN
BERING AND ALEUTIANS AND VERY BENIGN WEATHER WILL DOMINATE
THROUGH AT LEAST MID WEEK.

.LONG TERM FORECAST...MEDIUM RANGE MODELS INDICATE GENERALLY WEAK
STEERING FLOW FOR THE EXTENDED FORECAST PERIOD WITH A BROAD EAST-WEST
TROUGH FROM THE BERING TO THE GULF AND THE UPPER JET CONFINED TO
THE NORTH PACIFIC. RUN-TO-RUN CONSISTENCY IS POOR WITH HANDLING OF
SPECIFIC CUT-OFF LOWS EMBEDDED WITHIN THE TROUGH. THERE IS HIGHER
CONFIDENCE OVER THE INTERIOR OF ALASKA WHERE A THERMAL TROUGH AND
WEAK UPPER RIDGING SHOULD PERSIST...RESULTING IN SEASONABLE
TEMPERATURES...SOME SUNSHINE EACH DAY...AND A CHANCE OF
AFTERNOON/EVENING SHOWERS.

.AER/ALU...WATCH/WARNING SUMMARY
PUBLIC...NONE.
MARINE...GALE WARNING 130 132 138 150 160 170 172.
FIRE WEATHER...NONE.
