.SYNOPSIS...

The forecast will trend drier for the rest of this week as ridging
builds into the region. Occasional pockets of moisture embedded
within the trades will continue to produce mainly windward and
mauka showers for the next several days. Trade wind speeds could
decrease even further early next week as an overall drier trade
wind pattern continues.

.DISCUSSION...

Latest radar and satellite imagery shows a few showers moving
across the chain. A few low level clouds streaming in on the
trades and some mid to upper level clouds overhead is evident on
Nighttime Microphysics. Breezy trades are expected to continue for
the next few days due to a surface high that is far northeast of
the state.

Over the next couple of days, upper-level ridging will build into
the region from the east as the surface high to our northeast
weakens slightly but remains mostly stationary. Trades should
decrease slightly but still remain in the moderate to breezy
category. Conditions will begin to trend drier while some
lingering instability and pockets of moisture embedded within the
trade wind flow will still support typical windward and mauka
showers.

Looking into early next week, little change is expected as the
aforementioned surface high to the far northeast continues to move
eastward and weaken. This should weaken the trades at least for
the first half of next week.

.AVIATION...

Breezy trades will continue for the next few days. Low cigs and
SHRA should mainly impact windward and mauka locations. MVFR conds
possible in SHRA otherwise VFR prevails.

AIRMET Tango remains in effect for mod turb blw 080 downwind of
island terrain for all islands.

.MARINE...

High pressure northeast of the state will drive moderate to
fresh trade winds for the next several days. A disturbance
passing well north of the area late this weekend into early next
week may ease the pressure gradient slightly and allow trades to ease
a notch or two.

The current south swell will continue to provide near average
surf along south facing shores this morning but higher sets will
become more inconsistent. This swell will continue to gradually
fade to background levels later today into Friday. Models indicate
another small, long period south swell arriving late Sunday into
early next week that should boost south shore surf back up to near
average surf.

Surf along east shores will remain rough and choppy for the next
several days. Surf may lower a notch as the trade winds ease
late this weekend into early next week. Surf along north facing
shores will remain tiny through the period.

Peak high tides associated with the lunar cycle will cause minor
coastal flooding along shorelines and low lying coastal areas this
afternoon during the daily peak tide. The Coastal Flood Statement
remains in effect through this afternoon and may be dropped as
daily peak tides lower and south swell dissipates, lowering water
levels.
