HYDROMETEOROLOGICAL DISCUSSION
NWS ALASKA PACIFIC RIVER FORECAST CENTER ANCHORAGE AK
300 PM AKDT FRI JUL 3 2015 

...FLOOD POTENTIAL...

A SMALL STREAM FLOOD ADVISORY FOR DENALI WEST OF THE PARKS HIGHWAY 
HAS BEEN CANCELLED. 

THERE IS A POSSIBLE GLACIER DAMMED LAKE RELEASE FROM THE MENDENHALL 
GLACIER.  AT THIS TIME NO FLOODING IS EXPECTED FROM THIS POSSIBLE 
RELEASE.

ELSEWHERE ACROSS THE STATE... THE FLOOD POTENTIAL IS LOW.

...HYDROMETEOROLOGICAL DISCUSSION... 

THE UPPER LEVEL PATTERN TODAY HAS A SMALL LOW CENTERED IN THE 
WESTERN INTERIOR - SANDWICHED BETWEEN AN HIGH OVER EASTERN SIBERIA 
AND A RIDGE IN THE GULF - AND A LOW NEAR THE WESTERN ALEUTIANS WITH 
VARIOUS SHORTWAVES ROTATING AROUND IT.  THE LOW IN THE WESTERN 
INTERIOR IS BRINGING SHOWERS TO THAT REGION TODAY... AND THE 
ALEUTIAN LOW IS BRINGING RAIN TO THE ALEUTIANS AND SOUTHERN AKPEN 
TODAY.  OVERNIGHT THE WESTERN INTERIOR LOW WILL DRIFT SOUTHWESTWARD 
AND GET CAUGHT IN THE CIRCULATION AROUND THE ALEUTIAN LOW AS THE 
FIRST FRONT FROM THAT LOW SPREADS RAIN INTO THE SOUTHWEST MAINLAND 
AND SOUTHCENTRAL.  AS THIS HAPPENS THE RIDGE IN THE GULF AND THE 
SIBERIAN HIGH WILL CONNECT AND BRING WARM AND DRY CONDITIONS TO 
EASTERN AND NORTHERN ALASKA.

...PRECIPITATION...

PRECIPITATION TOTALS OVER THE 24 HOURS ENDING AT 4 AM TODAY:
