..FLOOD POTENTIAL
 
 
 
FLOOD POTENTIAL IS CURRENTLY LOW FOR THE STATE.  
   
..HYDROMETEOROLOGICAL DISCUSSION
 
 
THE LONG WAVE TROUGH NEARLY CENTERED OVER MAINLAND ALASKA AND  
EXTENDING WELL INTO EASTERN PACIFIC CONTINUES TO BE THE MAIN FEATURE  
AFFECTING THE STATE WITH RESPECT TO PRECIPITATION ON SATURDAY. THE  
SEMI PERMANENT LOW NEAR THE GULF KEPT THE SOUTHEAST AND MUCH OF THE  
GULF COAST IN STEADY RAIN. FARTHER NORTH OVER THE EASTERN MAINLAND  
LINGERING SHOWERS CONTINUED SATURDAY AFTERNOON.  
 
THE BERING SEA RIDGE CENTERED OVER THE CENTRAL ALEUTIANS EXTENDS  
FURTHER NORTH INTO THE POLAR REACHES OVER THE NEXT TWO DAYS AS IT  
BEGINS TO BEND EAST TOWARDS THE WEST COAST OF ALASKA. THE COMPLEX  
PATTERN OF TROUGHS AND EMBEDDED LOWS ON EITHER SIDE OF THE RIDGE  
OVER MAINLAND ALASKA AND EASTERN RUSSIA REMAINS PRETTY MUCH INTACT  
THROUGH MUCH OF NEXT WEEK. AN EASTERLY WAVE MOVING AROUND THE GULF  
LOW WILL AFFECT PORTIONS OF SOUTHCENTRAL TODAY AND TONIGHT WITH  
SOME SHOWERS. THE BIGGER STORY WILL BE THE SYSTEM THAT MODELS HAVE  
ENTERING THE NORTHWEST SUNDAY EVENING THEN QUICKLY SLIDES DOWN THE  
WESTERN MAINLAND MONDAY. A WIDE SWATH OF PRECIPITATION IS POSSIBLE  
ACROSS THE SOUTHERN MAINLAND.  
 
IN THE LONGER RANGE... THE HAZARDS OUTLOOK HAD HEAVY RAIN FOR THE  
PANHANDLE MONDAY AND TUESDAY IN RESPONSE TO THE NEXT WAVE OF ENERGY  
TO SWING AROUND THE LOW IN THE LONG WAVE TROUGH PATTERN. CURRENT  
MODELS RUNS ARE KEYING IN ON THIS AS WELL. AS IS WHAT ALWAYS SEEMS  
THE CASE... THE SOUTHEAST INTERIOR AND UPPER YUKON IS NOT FAR BEHIND  
IN RECEIVING SIGNIFICANT PRECIPITATION FROM THESE TYPE SYSTEMS AND  
CAN BE EXPECTED ON TUESDAY INTO WEDNESDAY.  
 
ABOVE NORMAL FREEZING LEVEL WERE BEGINNING TO SHOW UP ALONG THE  
WESTERN COAST WITH VALUES ABOVE 10000 FT (NOME AT 10700 FT AND  
BETHEL 9900 FT). OTHERWISE VALUES STATEWIDE WERE MUCH BELOW NORMAL  
AND BETWEEN 5400 FT AT FAIRBANKS AND 7800 FT AT ANNETTE.  
 
PRECIPITATION... SELECTED PRECIPITATION TOTALS OVER THE 24 HOURS  
ENDING AT 4 AM TODAY:
