The inverted surface trough, situated near 170W Monday morning, is
forecast to linger in place through Wednesday night, and then
flatten out by the end of the week based on the latest model
guidance.  Meanwhile, the main surface high will generally be
situated northeast of the Islands through the upcoming week.  The
ensemble means indicate a weak positively tilted upper trough over
the state by next weekend, and an upper ridge building northwest
of the state.

In terms of sensible weather, the trades should generally be from
the east with some ESE component at times through Thursday, and
then slightly backing to the ENE for next weekend as the ridge
builds more to the north of the state.  The normal trade enhanced
showers can be expected most days, with the heaviest rain for the
Big Island, but no major rainfall events appear likely at this
time.
