HYDROMETEOROLOGICAL DISCUSSION
NWS ALASKA PACIFIC RIVER FORECAST CENTER ANCHORAGE AK
300 PM AKDT SUN JUL 27 2014 

...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:
