308 am hst Sat sep 23 2017

Synopsis
Trade winds will gradually trend down this weekend as a ridge of
high pressure to the north weakens and a weak surface trough
slowly approaches from the east. Mainly windward clouds with light
passing showers will prevail into early next week, with a
possible boost in shower activity around the middle of next week
as the surface trough moves through the islands.

Discussion
Currently at the surface, a 1026 mb high is centered around 1750
miles north-northeast of honolulu, and is driving light to
moderate trade winds across the island chain early this morning.

Meanwhile, a weak surface trough is located around 550 miles
northeast of hilo. Infrared satellite imagery shows clear to
partly cloudy skies in place across the state, with some thin
cirrus streaming northeastward over the big island. Radar imagery
shows scattered light showers moving into windward areas, with
predominantly rain free conditions elsewhere. Main short term
concerns revolve around the diminishing trades and rain chances
over the next couple of days.

Today through Tuesday,
high pressure will weaken and shift eastward as the weak surface
trough northeast of the state shifts slowly westward toward the
island chain. This will result in a gradual easing of the trade
winds this weekend, with mainly light trades expected for the
first half of next week. Showers will continue to favor windward
and mauka areas through the period, although some leeward shower
development will be possible each day due to the weakened trades.

Overall, fairly dry conditions are expected through the period
given precipitable waters values in the 1.0 to 1.3 inch range,
well below climatological norms for this time of year.

Tuesday night through Friday,
the surface trough will shift westward across the island chain
during the middle of next week. This should bring an increase in
shower activity, as well as strengthening the trade wind flow
back to moderate levels. Showers will continue to favor windward
and mauka areas through the period.

Aviation
Except for the chance of brief MVFR conditions in passing showers
over windward and mauka sections across the island chain,VFR
will predominate.

No airmets are currently in effect, and none are anticipated
through the day.

Marine
Trade wind speeds will remain below the small craft advisory
threshold through the forecast period.

Surf along south facing shores will remain small through early next
week, with mainly background southeast and southwest swell energy
expected. The next potential long-period pulse out of the
southwest from the tasman sea is expected by Sunday and could
lead to a slight increase in surf. For the extended forecast,
strong to gale-force southwest winds associated with a low in the
tasman sea may lead to another small southwest swell Tuesday
through midweek.

A small northwest swell will continue into the weekend before
easing. Another small reinforcement from that direction is
expected to fill in around Sunday night through the middle of next
week.

Hfo watches warnings advisories
None.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
