.ANALYSIS AND UPPER LEVELS...

THE STATUS QUO REMAINS FROM THE LAST FEW DAYS WITH A LONG WAVE UPPER 
TROUGH SOUTH OF THE ALEUTIANS AND AN UPPER RIDGE OVER INTERIOR 
ALASKA. A LARGE VERTICALLY STACKED LOW PRESSURE SYSTEM, ANCHORING 
THIS TROUGH, CONTINUES TO SPIN SOUTH OF THE ALEUTIANS. A BROAD 
SURFACE LOW EMBEDDED IN THE TROUGH CONTINUES TO MOVE WESTWARD IN THE 
SOUTHERN BERING SEA AND IS PRODUCING OVERCAST CONDITIONS THROUGHOUT 
THE ALEUTIANS AND EVEN LIGHT RAIN SHOWERS AROUND SAND POINT AND 
DUTCH HARBOR ACCORDING TO LATEST OBSERVATIONS.

FURTHER EAST, YET ANOTHER LOW HAS MOVED UP FROM THE PACIFIC AND IS 
NOW TAKING A VERY SIMILAR TRACK TO YESTERDAY'S LOW ACROSS THE 
SOUTHERN GULF OF ALASKA TOWARD KODIAK AND THE ALASKA PENINSULA. THIS 
IS BRINGING ANOTHER ROUND OF STEADY RAIN TO KODIAK. OUT AHEAD OF 
THIS, KING SALMON RADAR SHOWS LIGHT RAIN SHOWERS ACROSS THE BRISTOL 
BAY/ALASKA PENINSULA REGION. THE APPROACH OF THE LOW AND ASSOCIATED 
OCCLUDED FRONT ARE LEADING TO SMALL CRAFT WINDS ACROSS THE KODIAK 
ISLAND COASTAL WATERS. 

HIGH PRESSURE ALONG THE GULF COAST COMBINED WITH AFTERNOON 
HEATING/THERMAL LOW PRESSURE INLAND IS CAUSING GAP WINDS TO INCREASE 
IN SOUTHCENTRAL AS THE AFTERNOON CARRIES ON. THIS INCLUDES THE 
TURNAGAIN ARM INTO ANCHORAGE, THE KNIK RIVER VALLEY INTO PALMER, AS 
WELL AS THE SOUTHERN COPPER RIVER BASIN. MEANWHILE, AN UPPER LEVEL 
TROUGH DIGGING SOUTHWARD FROM NORTHERN ALASKA LOOKS TO OFFER UP A 
PATTERN CHANGE TOMORROW FROM THE WARM AND DRY CONDITIONS TO COOLER 
AND CLOUDY CONDITIONS.
