AREA FORECAST DISCUSSION
SOUTHCENTRAL AND SOUTHWEST ALASKA
500 AM AKDT THU JUL 9 2009

.ANALYSIS AND UPPER LEVELS...
IN THE UPPER-LVLS A TROF IS DRAPED THROUGH THE BERING WITH AN UPPER
LOW SOUTH OF THE CENTRAL ALEUTIANS. A RIDGE IS PREDOMINANT THROUGH
THE GULF OF AK INTO THE CENTRAL MAINLAND. A SHORTWAVE TROF IS
ROTATING THROUGH CENTRAL AK...SE INTO THE N COPPER RIVER BASIN.
ANOTHER SHORTWAVE IS ROTATING TOWARDS THE UPPER KUSKOWIM VALLEY
MOVING EAST. AT THE SURFACE A LOW NORTHWEST OF SHEMYA IS FILLING
QUICKLY AS IT MOVES INTO THE NW BERING. ANOTHER LOW IS DEVELOPING
SOUTHWEST OF THE FAR WESTERN ALEUTIANS MOVING EAST.

.MODEL DISCUSSION...
MODELS SATISFACTORILY HANDLING MAIN FEATURES THROUGH THE SHORT-TERM
FORECAST. THE UPPER LOW SOUTH OF THE CENTRAL ALEUTIANS TRYING TO
UNDERCUT THE UPPER-RIDGE OVER THE MAINLAND AND LOOKS TO STRUGGLE. THE
LOW ROTATING TOWARDS THE GULF IS APPEARING TO BE WEAKER AND FURTHER
SOUTH IN ITS EVENTUAL PROGRESSION. CONSISTENCY IN THE SOLUTIONS
ADEQUATE AT BEST.

.SHORT TERM FORECAST...
.SOUTHCENTRAL...
SHOWERS AND T-STORMS TODAY THROUGH THE COPPER RIVER BASIN...AND ALSO
THE MOUNTAINS OF THE SUSITNA VALLEY AS SERIES OF SHORTWAVES ROTATE
THROUGH THE INTERIOR MAINLAND. UPPER-RIDGE OVER THE ANCHORAGE BOWL
AND KENAI PENINSULA FLATTENS A BIT AS THE UPPER-FEATURES ROTATE
THROUGH...BUT RE-BUILDS BY THE WEEKEND. IN THE INTERIM...ONGOING
FOREST FIRES WILL CONTINUE TO YIELD HAZE AND SMOKE FOR A FAIRLY LARGE
SWATH OF THE ZONE...PARTICULARLY OVER THE COPPER RIVER BASIN AND
KENAI PENINSULA.

.SOUTHWEST...
AREAS OF FOG/STRATUS ACROSS THE AKPEN AND KUSKOWIM DELTA GENERALLY
GIVING WAY TO OFF-SHORE FLOW FROM NORTH TO SOUTH. AS SUCH WARMER
TEMPERATURES FROM THE INTERIOR TO NOSE DOWN TOWARDS COASTAL AREAS
TOMORROW.

..BERING SEA AND ALEUTIANS...
UNSETTLED WEATHER CONTINUING THROUGH THE WEEKEND AS RAIN OVERSPREADS
THE ZONE FROM SERIES OF LOW PRESSURE SYSTEMS.

.LONG TERM FORECAST...
AN OVERALL PATTERN SHIFT EARLY TO MID NEXT WEEK AS PREDOMINANT RIDGE
OVER THE MAINLAND BREAKS DOWN AND LONG-WAVE TROF OVER THE BERING
MOVES EAST. AS SUCH MORE SEASONABLE TEMPERATURES AND A GREATER CHANCE
OF PRECIPITATION CAN BE EXPECTED FOR MUCH OF THE AOR.
