Area Forecast Discussion
National Weather Service Honolulu HI
1010 AM HST THU JUN 30 2016

.SYNOPSIS...
Trade winds will continue over the islands for the foreseeable
future, becoming strong and gusty by Friday, and remaining that way
through the holiday weekend. A dry and stable air mass is expected
to move over the islands from the east by tonight, with mostly dry
conditions continuing into Saturday. The airmass will gradually
moisten from late Saturday through Monday, leading to increasing
trade wind showers that will spread leeward on the smaller islands.

&&

.DISCUSSION...
Surface high pressure centered far NE of the islands will strengthen
somewhat and move slowly W the next couple of days. This will lead
to increasing trade winds over the next 12 to 36 hours, with breezy
to locally windy conditions expected to persist through the holiday
weekend.

Model guidance continues to indicate significant drying of the
island air mass later today through Friday as a strong mid-level
ridge builds over the islands at the same time a significant dry
slot moves in from the E. Shower chances will be quite low, and any
precipitation that occurs will be light, and amount to very little.
Along the leading edge of the encroaching dry air mass, a relatively
narrow area of increased low clouds and showers is noted, with this
feature tracking steadily W, currently along the longitude of the
Big Island and Maui.

The interaction between the strengthening winds, the strong
stability and island terrain is expected to lead to locally strong
wind gusts, especially over mountain ridges and to the lee of the
mountains. Wind gusts may become strong enough to support the
issuance of a wind advisory,especially Friday and Saturday, when the
low-level subsidence inversion is expected to be especially low and
strong.

The base of the inversion will gradually rise from late Saturday
into Monday, as moisture embedded within the trade wind flow
increases from the unusually dryness seen Friday and Saturday. The
GFS and ECWMF have been consistent with most aspects of the forecast
through the weekend, so confidence is fairly high. This moistening
will lead to gradually increasing trade wind showers, with a fairly
typical trade wind weather pattern delivering passing showers for
July 4th outdoor activities on Sunday and Monday. With the moisture
depth increasing to near 10 kft, showers may more easily spread
leeward on the smaller islands, with the potential for the trade
wind flow to become somewhat showery into Wednesday. Diminishing
moisture is expected to lead to fewer trade showers for the second
half of next week, while trade wind speeds gradually ease.

A persistent and slow-moving trough aloft will remain several
hundred miles W of the islands through the middle of next week. This
feature is expected to remain sufficiently far from the islands to
not destabilize the island atmosphere, but associated SW flow over
the islands will carry varying amounts of mid- and high-level clouds
over the islands into the middle of next week.

&&

.AVIATION...
Clouds and scattered showers will remain focused over windward areas
today, with isolated MVFR conditions possible. VFR conditions will
prevail elsewhere across the state. A drier airmass will move into
the state from the east this afternoon and tonight, with showers
decreasing even over the windward areas.

Trade winds will increase through tonight, and AIRMET TANGO for low
level turbulence over and south through west of the mountains will
remain in effect.

&&

.MARINE...
A Small Craft Advisory (SCA) is in effect for most Hawaiian waters
already, or starting tonight. The SCA will be continuing for all of
these waters through Sunday afternoon. A gale watch remains in place
for the Pailolo and Alenuihaha Channels, and the waters south of the
Big Island, starting tonight and continuing through Saturday as the
trades are forecast to strengthen to gale force over these waters
by Friday.

Surf is expected to remain below the high surf advisory criteria
along all shorelines through Friday. As the trade winds strengthen,
expect elevated rough surf along windward shores, and a high surf
advisory for the E facing shores will likely be necessary starting
Saturday, and continuing into early next week.

&&

Gale Watch from 6 PM HST this evening through Saturday afternoon for
Pailolo Channel-Alenuihaha Channel-Big Island Leeward Waters-Big
Island Southeast Waters.
