DEVELOPING OMEGA BLOCK PATTERN ALONG THE DATELINE IN THE HIGH
LATITUDES WILL FAVOR AN UPPER LOW TO REMAIN WEST OF THE REGION,
NEAR 170E, WHILE THE ISLAND CHAIN REMAINS IN BETWEEN HIGHER THAN
NORMAL HEIGHTS IN THE DEEP TROPICS AND LOWER HEIGHTS IN THE MID-
LATITUDES. BREEZY TRADES DUE TO A STRONG SURFACE HIGH WELL TO THE
NORTHWEST WILL SUBSIDE A BIT THIS WEEKEND AS THE PRESSURE GRADIENT
RELAXES. DEEP MOISTURE WILL REMAIN SOUTH OF THE REGION, BUT
PRECIPITABLE WATER VALUES MAY INCREASE FROM THE SOUTHEAST EARLY
NEXT WEEK WHICH MAY PROMOTE A BIT MORE RAIN OVER AT LEAST THE BIG
ISLAND. OTHERWISE, RELATIVELY DRY CONDITIONS WILL STAY IN THE
FORECAST WITH WINDWARD/MAUKA SHOWERS. BY MIDWEEK NEXT WEEK, TRADES
WILL INCREASE AGAIN AS ANOTHER HIGH PRESSURE DEVELOPS NEAR 30N.
