300 PM AKDT FRI FEB 08 2013

...FLOOD POTENTIAL... 
SIGNIFICANT RAIN IS EXPECTED NEAR SEA LEVEL OVER NORTHERN SOUTHEAST 
FROM YAKUTAT TO SITKA ON SATURDAY INTO SUNDAY.  HEAVY SNOW IS 
EXPECTED AT HIGHER ELEVATIONS IN THIS REGION.  THE RAIN MAY CAUSE 
LOCAL PONDING PROBLEMS... BUT FLOODING IS NOT EXPECTED AT THIS TIME. 

FLOOD POTENTIAL FOR THE REST OF ALASKA IS LOW AT THIS TIME. 

...HYDROMETEOROLOGICAL DISCUSSION... 
THE PATTERN HAS BEEN PROGRESSIVE OVER THE PAST WEEK.

THE CURRENT UPPER LEVEL PATTERN HAS A RIDGE FROM THE NORTH PACIFIC 
INTO BRITISH COLUMBIA AND THE GULF... A NARROW TROUGH WITH SEVERAL 
EMBEDDED LOWS CURVING FROM A LOW NEAR THE CANADIAN ARCHIPELAGO TO 
THE BERING STRAIT THEN TO THE EASTERN ALEUTIANS AND ON TO A LOW IN 
THE NORTH PACIFIC... AND ANOTHER RIDGE FROM THE NORTH PACIFIC OVER 
THE WESTERN BERING AND ON NORTHWARD ACROSS EASTERN SIBERIA.  THE 
NORTH GULF LOW WILL MOVE TO THE AKPEN BY SATURDAY MORNING... AS THE 
ASSOCIATED FRONT DEVELOPS A SUBTROPICAL CONNECTION.  AS THE FRONT 
MOVES EASTWARD IT WILL BRING SIGNIFICANT PRECIPITATION (RAIN NEAR 
SEA LEVEL, SNOW AT HIGHER ELEVATIONS) TO NORTHERN SOUTHEAST SATURDAY 
AFTERNOON INTO SUNDAY.

LONG RANGE FORECASTS SHOW THE PATTERN CONTINUES TO BE BASICALLY 
PROGRESSIVE THROUGH NEXT WEEK.
