...HYDROMETEOROLOGICAL DISCUSSION...

THE UPPER LEVEL PATTERN THIS MORNING STILL HAS THE NORTHERN LOW WELL
NORTH OF THE NORTH SLOPE WITH A FRONT SOUTH TO CANADA AND THEN
ACROSS NORTHERN AND INTERIOR ALASKA.  THE RIDGE OVER THE BERING IS
SLOWLY BUILDING INTO THE WESTERN INTERIOR AND SOUTHERN MAINLAND.
THERE IS ALSO A WEAK TROUGH SOUTH OF THE ALEUTIANS AND ACROSS THE
GULF... WITH WEAK EMBEDDED LOWS SOUTH OF THE ALEUTIANS AND NEAR
SOUTHEAST ALASKA.

RAIN ASSOCIATED WITH THE FRONT FROM THE NORTHERN LOW IS EXPECTED TO
BE DIMINISHING TO SHOWERS AS IT DROPS SOUTH AND WEAKENS TODAY.  A
SHORTWAVE ROTATING AROUND THE NORTHERN LOW WILL BRING MORE RAIN TO
THE NORTH SLOPE ON SUNDAY INTO MONDAY.  THE LOW NEAR SOUTHEAST WILL
STRENGTHEN AS IT MOVES EAST... BRINGING RAIN TO SOUTHEAST ON SUNDAY
AND MONDAY.
