HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
340 AM EDT SUN APR 28 2024
VALID 00Z MON APR 29 2024 - 00Z MON MAY 06 2024
GENERALLY EAST-SOUTHEAST TO EAST WINDS ARE PRESENT ACROSS HAWAII,
WITH THE SLIGHT VEERING OF THE WINDS DUE TO UPPER AND SURFACE LOWS
TO THE NORTHWEST OF THE STATE. THESE WINDS SHOULD STAY LIGHT TO
MODERATE OVER THE EASTERN ISLANDS THROUGH THE FIRST PART OF THE
WEEK, BUT WEAK ENOUGH OVER THE NORTHWESTERN ISLANDS TO ALLOW FOR A
HYBRID TRADE AND LAND/SEA BREEZE PATTERN. MEANWHILE, AVAILABLE
MOISTURE IS FORECAST TO LESSEN OVER THE NEXT COUPLE OF DAYS FOR
LESS SHOWER COVERAGE. WHAT IS LEFT OF THE WEAKENING TROUGH MAY
MOVE ACROSS HAWAII AROUND TUESDAY.
FOR MIDWEEK AND BEYOND, SURFACE HIGHS DEVELOPING NORTH OF THE
STATE WILL LEAD TO GRADUALLY INCREASING EASTERLY TRADES, REACHING
MODERATE TO BREEZY LEVELS BY FRIDAY OR THE WEEKEND. MEANWHILE BY
LATE NEXT WEEK INTO THE WEEKEND, MODEL GUIDANCE IS COMING INTO
BETTER AGREEMENT IN SHOWING A MID-UPPER TROUGH/LOW OVER HAWAII.
THIS COULD PROVIDE SOME INSTABILITY FOR INCREASED SHOWERS, WHICH
WOULD FAVOR WINDWARD AREAS GIVEN THE INCREASING TRADES.
