Models and ensembles reasonably agree that a weak front with some
pooled moisture and a few showers works across the islands today.
This front should stall near the Big Island tomorrow then
gradually weaken and regress into late week. Heights rise through
next weekend into next Monday over the state usher in a more
typical trade pattern, albeit with limited rainfall potential.
Flow amplification over the Pacific may also lead to the gradual
approach of an amplified western Pacific mid-upper level trough
that may force a well defined front with enhanced convection to
just west of the islands in 7/8 days. Forecast spread and
uncertainty increases at these longer time frames, but would favor
a solution on the slower side of the full envelope of solutions
given flow amplification.
