IT GENERALLY REMAINS THE CASE THAT A COMPOSITE OF REASONABLY WELL
CLUSTERED MODEL AND ENSEMBLE GUIDANCE REMAINS PREFERRED AND
MAINTAINS GOOD CONTINUITY THROUGH MUCH OF THE NEXT WEEK. WINDS
SHOULD GRADUALLY INCREASE OVER THE NEXT COUPLE OF DAYS ALONG WITH
MODEST SHOWERS AS MOISTURE LEVELS SLOWLY RETURN CLOSER TO NORMAL.
A FRONTAL DRAPE AND ENERGETIC EMBEDDED IMPULSE/SYSTEM TRACK WILL
SET UP JUST NORTH OF HAWAII THIS WEEK DOWNSTREAM OF AN AMPLIFIED
BUT POSITIVE TILT WEST-CENTRAL PACIFIC UPPER TROUGH IN SPLIT
SOUTHERN STREAM FLOW. FRONTAL PROXIMITY MAY DRAW SOME SOUTHERLY
WINDS AND DEEPER MOISTURE INTO THE STATE. EXPECT THE FRONT MAY
TEMPORARILY SINK SOUTH ENOUGH TO FOCUS POOLED MOISTURE AT LEAST
ACROSS THE WESTERN ISLANDS FOR A WETTER PATTERN, ESPECIALLY
TUESDAY INTO WEDNESDAY/THURSDAY IN THE WAKE OF ORGANIZING FRONTAL
LOW PASSAGE SLATED JUST TO THE NORTH OF THE STATE.
