HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
654 AM EST SUN FEB 14 2016

VALID 00Z MON FEB 15 2016 - 00Z MON FEB 22 2016

A RIDGE OF HIGH PRESSURE BUILDS NORTH OF THE ISLANDS EARLY THIS
WEEK, WITH LOW LEVEL WINDS TURNING TO THE EAST NORTHEAST. FROM MID
TO LATE WEEK, RELATIVE HUMIDITY FROM THE SFC-500 MB WILL DROP
BELOW 50 PERCENT.  WHILE BRISK NORTHEAST FLOW SUPPORTS A FEW
WINDWARD SHOWERS, COVERAGE WILL BE WIDELY SCATTERED AND AMOUNTS
LIGHT DUE TO LIMITED AVAILABLE MOISTURE.

NEXT WEEKEND HAWAII WILL HAVE A TROUGH OF LOW PRESSURE MOVE
THROUGH AS A FRONT APPROACHES FROM THE NORTHWEST.  THE APPROACHING
FRONT SHOULD WEAKEN AS IT PASSES THROUGH DURING THE FIRST HALF OF
THE WEEK.  AN ASSOCIATED BAND OF MOISTURE WITH PRECIPITABLE WATER
VALUES IN THE 1.00 TO 1.25 INCH RANGE WILL SUPPORT A FEW SHOWERS
IN ADVANCE OF THE FRONTAL PASSAGE NEXT WEEKEND.
