HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
352 AM EDT SUN JUN 22 2025
VALID 00Z MON 23 JUN 2025 - 00Z MON 30 JUN 2025
A GENERALLY DRY SUNDAY IS ON TAP FOR HAWAII, WHILE EASTERLY TRADES
WILL BE WINDY UNDER A TIGHT PRESSURE GRADIENT FROM A SURFACE HIGH
CENTERED NORTHEAST OF THE STATE. THIS MAY LEAD TO FIRE WEATHER
CONCERNS. BUT BY MONDAY AND BEYOND, TRADES WILL GRADUALLY LESSEN
TO MODERATE TO LOCALLY BREEZY LEVELS BY MIDWEEK. MEANWHILE A WEAK
LOW ALOFT MAY ALLOW FOR A RAISED INVERSION WHILE WAVES OF HIGHER
MOISTURE MOVE THROUGH. THIS SHOULD LEAD TO A COMPARATIVELY WETTER
TRADE WIND PATTERN, AS MOISTURE LEVELS PEAK AROUND TUESDAY-
THURSDAY. SHOWERS SHOULD FAVOR WINDWARD AND MAUKA AREAS, BUT HEAVY
RAIN IS NOT EXPECTED. SOME ENHANCED MOISTURE COULD LINGER LATE
WEEK INTO NEXT WEEKEND, BUT A MID/UPPER HIGH MAY SNEAK INTO AT
LEAST THE EASTERN ISLANDS AND SUPPRESS SOME POTENTIAL SHOWERS.
