.SYNOPSIS...
Breezy trades focus clouds and showers windward and mauka for the
next week especially at night and early morning.
&&
.DISCUSSION...
Strong stability prevails and is characterized by a stout trade wind
inversion that slopes slightly downward from around 7kft at Kauai to
6kft at Hilo. Moisture remains trapped beneath the inversion leading
to a rather impressive coverage of showers in recent nights despite
synoptically dry and stable conditions. Suspect this pattern will
continue as the latest modeling indicates high stability persisting
through the forecast period. As such, strong June diurnal warming
above cloud tops will easily suppress daytime convection while
nighttime shower coverage overachieves. Shower intensity will remain
light as capping remains strong and moisture depth remains
relatively shallow. Mid-level ridging anchored N to NE of the
islands maintains breezy trades for at least the next 7 days.
&&
.AVIATION...
Moderate to breezy and gusty trades will gradually increase
through Monday. Low cigs and SHRA will be mostly focused over
windward and mauka locations. Some spillover to leeward sides
isn`t out of the question. MVFR conds possible in any SHRA
otherwise VFR prevails.
AIRMET Tango is in effect for mod turb downwind of island terrain.
This will likely continue through the weekend as trade winds
strengthen.
&&
.MARINE...
High pressure north of the region will strengthen and dominate
through the forecast period. As a result, trade winds will increase
a notch through the rest of this weekend and remain through next
week. A Small Craft Advisory (SCA) for the windier waters and
channels around Maui County and the Big Island remains in effect
through Monday, but will likely need to be extended and possibly
expanded in coverage as the trades strengthen.
A series of small, long-period, south swells originating near New
Zealand will help boost surf heights to near the summer average
(5 feet) throughout next week. The first of these should fill in
Sunday into Monday, followed by another Wednesday into Thursday
of next week.
Rough and choppy surf along east facing shores is expected to
slightly increase into early next week due to the strengthening
trade winds. Surf will remain at seasonable levels (nearly flat)
along north facing shores throughout the forecast period, though
select exposures could see some tradewind swell wrap.
&&
.HFO WATCHES/WARNINGS/ADVISORIES...
Small Craft Advisory until 6 PM HST Monday for Maalaea Bay-
Pailolo Channel-Alenuihaha Channel-Big Island Leeward Waters-Big
Island Southeast Waters.
