HYDROMETEOROLOGICAL DISCUSSION
NWS ALASKA PACIFIC RIVER FORECAST CENTER ANCHORAGE AK
300 PM AKDT WED MAY 22 2013

...FLOOD POTENTIAL... 

THE ICE JAM UPSTREAM OF FORT YUKON REMAINS IN PLACE TODAY... BUT 
WATER IS MOVING AROUND THE JAM AND THROUGH A SMALL BREACH IN THE 
JAM.  THE RISK OF MODERATE OR MAJOR FLOODING IN FORT YUKON HAS BEEN 
REDUCED SIGNIFICANTLY... BUT MINOR FLOODING IS EXPECTED TO CONTINUE.

SEE THE BREAKUP MAP AND THE BREAKUP SUMMARY FOR CURRENT BREAKUP 
ACTIVITY... INCLUDING FLOOD WATCHES AND WARNINGS.

THE POTENTIAL FOR NON-BREAKUP RELATED FLOODING IS CURRENTLY LOW 
FOR THE STATE OF ALASKA.

...HYDROMETEOROLOGICAL DISCUSSION...

AN UPPER LEVEL LOW PRESSURE IN THE BERING SEA IS CONTINUING TO PUSH 
SOME PRECIPITATION INTO SOUTHWEST ALASKA AND UP THE WEST COAST.  AN 
UPPER LEVEL HIGH PRESSURE RIDGE HAS KEPT SUNNY SKIES AND WARMER 
TEMPERATURES OVER THE EASTERN PORTION OF THE STATE AND THE 
PANHANDLE. THE FRONT IN THE WEST WILL WEAKEN TODAY AS IT SLOWLY 
MOVES INTO THE CENTRAL MAINLAND... THE FAR EASTERN MAINLAND AND THE 
PANHANDLE SHOULD REMAIN DRY.

FREEZING LEVELS WERE NEAR THE SURFACE ACROSS MOST OF THE STATE OVER 
THE PAST WEEKEND... BUT HAVE NOW CLIMBED TO BETWEEN 3000 AND 5400 
FEET.

SELECTION OF PRECIPITATION TOTALS FOR 24 HOURS ENDING AT 4AM: 

LOCATION NAME                 PE TS    24 HR  
======== ====                 == ==

...FORECAST PRECIPITATION... 

LIGHT PRECIPITATION IS EXPECTED OVER MOST OF WESTERN ALASKA TODAY... 
WITH MAINLY SHOWERY PRECIPITATION LIKELY ON FRIDAY.

...QUANTITATIVE PRECIPITATION FORECASTS (QPF) GRIDS... 

DAY 1-3 QPF GRIDS WERE BASED ON A BLEND OF THE NAM AND GFS... WITH 
SOME MANUAL EDITS.  DAY 4-7 QPF GRIDS WERE BASED ON THE GFS... WITH 
OCCASIONAL MANUAL EDITS. 

...LONG RANGE...
THE 6 TO 10 DAY TEMPERATURE OUTLOOK HAS INCREASED CHANCES OF ABOVE 
NORMAL TEMPERATURES OVER ALL OF THE MAINLAND AND THE PANHANDLE.
 
THE 6 TO 10 DAY PRECIPITATION OUTLOOK HAS INCREASED CHANCES OF BELOW 
NORMAL PRECIPITATION OVER ALL OF THE MAINLAND AND SOUTHEAST ALASKA.
