.MODEL DISCUSSION...INITIALIZATIONS APPEAR REASONABLE. FORECAST
SOLUTIONS SYNOPTICALLY ARE IN GENERAL AGREEMENT THRU SUN
AFTERNOON(60HR). SOLUTIONS VARY SOME AFTER THIS WITH THE ECMWF AND
GFS REASONABLY CLOSE TO MON AFTERNOON. HOWEVER...THE STRENGTHENING
NORTH PACIFIC JET WILL PROVIDE SOME TIMING CHALLENGES OF SURFACE
FEATURES OVER THE NEXT COUPLE OF DAYS.

.UPPER LEVELS(500 MB)...
AN UPPER LEVEL LOW CENTERED NEAR SAND POINT IS GRADUALLY WEAKENING AS
IT MOVES SOUTH. THIS LOW WILL CONTINUE TO DRIFT SOUTH OF THE GULF OF
AK AND WEAKEN WHILE A SECONDARY LOW DEVELOPS SOUTH OF KODIAK SAT.
RIDGING BUILDS ALONG THE NORTH GULF COAST AND SOUTHERN MAINLAND
TONIGHT AND SAT. THE RIDGE AXIS IS PUSHED NORTH TO OVER THE CENTRAL
MAINLAND SUN AS KODIAK CENTER LIFTS SLOWLY NORTH. RIDGING OVER THE
BERING SEA FLATTENS SAT NIGHT AS A LOW EAST OF KAMCHATKA MOVES TO THE

980S LOW JUST SOUTH OF THE AK PEN MOVES SOUTH OF THE GULF OF AK AND
WEAKENS. ITS ASSOCIATED FRONT MOVES NORTH AND EAST THROUGH SAT AND

CENTER MOVES TO JUST EAST OF THE KAMCHATKA PEN TONIGHT THEN DEEPENS
INTO THE 960S AS IT MOVES INTO THE CENTRAL BERING SEA SUN. ITS
ASSOCIATED FRONT IMPACTS THE WESTERN ALEUTIANS TONIGHT AND MOVES TO
THE WESTERN AK PEN SUN MORNING.

SOUTHCENTRAL...
.SOUTHCENTRAL...RAIN WILL SPREAD TO MOST GULF LOCATIONS TONIGHT AND
CONTINUE INTO SUN. GENERAL DOWNSLOPE CONDITIONS WILL KEEP
PRECIPITATION TO A MINIMUM INLAND EXCEPT FOR EAST AND SE EXPOSURES.
PRESSURE GRADIENTS WILL INCREASE IN ADVANCE OF LOW CENTER AND BRING
SOME GALES TO COASTAL WATERS TONIGHT AND SAT AND BRISK GAP FLOWS TO
SOUTHCENTRAL. WINDY CONDITIONS ARE EXPECTED TO CONTINUE INTO
SUN...WITH A FEW BRIEF REPRIEVES.

.SOUTHWEST MAINLAND/AK PEN...GUSTY NORTHERLY WINDS ARE BRINGING
DRYING CONDITIONS TO MUCH OF SW ALASKA THIS AFTERNOON. CONDITIONS
SHOULD REMAIN GENERALLY DRY THROUGH SAT. MOISTURE FROM THE GULF WILL
INTRUDE IN FROM THE SOUTH ON SUN.
NORTHERLY FLOW WILL INCREASE ACROSS THE AK PEN TONIGHT AS LOW CENTER
MOVES SOUTH. WINDS WILL DIMINISH SAT. NORTHERLY FLOW WILL KEEP
SHOWERS ACROSS MUCH OF THE NORTHERN AK PEN INTO SAT.

.ALEUTIANS...WINDS ACROSS THE EAST ALEUTIANS WILL DIMINISH OVERNIGHT
AS THE LOW NEAR THE AK PEN MOVES SOUTH AND WEAKENS. A STRONG LOW
MOVING INTO THE WESTERN PACIFIC AND ASSOCIATED FRONT WILL BRING SE
GALES/STORMS TO THE WESTERN ALEUTIANS/BERING SEA TONIGHT. GALES WILL
SPREAD ACROSS THE BERING SEA THROUGH SAT. SW STORMS/GALES TO SOUTH OF
