The 7 day forecast for Hawaii looks relatively tranquil while a
couple tropical cyclone do not appear to pose to impact the state
during this period.

Precipitable water values at least indicated by the operational
GFS start out about 1.5 inches and then remain between 1.5 and
1.75 inches through Wednesday before falling to around 1.25 inches
from Wednesday through Sunday, indicating some drying during this
period.

The trade wind regime is associated with a large sprawling surface
1033 to 1034 mb anticyclone near 40N 155W that then drifts slowly
west to near 40N 160W by Thursday and then drifts slowly eastward
to near 150W through the end of the forecast.  At upper levels,
Hawaii is located between two upper lows over the central Pacific
with the eastern low drifting westward to just north of the
Islands by next weekend.

The various model and ensemble qpf forecasts have a pretty
consistent look to them on all forecast days with no daily
enhancements yet evident on any of the higher resolution model
runs so a fairly typical trade wind regime remains in order. 
There are the potential for tropical cyclogenesis that remain well
east of the Islands through the period.  Please refer to the
Central Pacific and National Hurricane Centers for any possible
updates on these systems.
