VALID 00Z SAT 13 JUN 2026 - 00Z SAT 20 JUN 2026
A FRONTAL BOUNDARY ASSOCIATED WITH AN UPPER-LEVEL TROUGH CENTERED
WELL NORTH OF THE ISLANDS WILL REMAIN NORTHWEST OF THE STATE,
DRIFTING FARTHER WEST AS THE UPPER TROUGH LIFTS OUT EARLY NEXT
WEEK. PRIOR TO ITS DEPARTURE, LIGHT WINDS AND BELOW-NORMAL
PERCEPTIBLE WATER (PW) ANOMALIES WILL CHARACTERIZE THE LOCAL
AIRMASS. EAST OF THE FRONT, SURFACE RIDGING WILL BUILD BACK IN
NORTH OF THE ISLANDS, SUPPORTING A RETURN OF MORE TYPICAL EASTERLY
TRADES EARLY NEXT WEEK. DEEPER MOISTURE IS FORECAST TO RETURN
LATE SUNDAY ALONG WITH THE INCREASING TRADES, WITH ABOVE-NORMAL
PWS ANOMALIES THEN PERSISTING THROUGH MUCH OF THE WEEK. HOWEVER,
TRADE WINDS MAY SLACKEN AGAIN BY THE MIDDLE PART OF THE WEEK AS
ANOTHER UPPER-LEVEL TROUGH BEGINS TO AMPLIFY NORTH OF THE STATE.
