The subtropical high that is currently situated north of Hawaii
near 35 degrees north is forecast to slowly drift to the
northeast, and then become nearly anchored in place near 145
degrees west through the weekend and into early next week.  The
Islands will be on the southwestern periphery of this high through
most of the forecast period with good agreement among the ensemble
means, although the GEFS mean has the high centered a little
closer to the state mid-late next week.  This will also be
co-located with a building upper level high in the same general
region.

In terms of sensible weather, low level trades should generally be
out of the east with some occasional ENE or ESE component at
times, with moderate flow velocities expected.  Most of the
terrain enhanced showers should be across the Big Island, and
lighter QPF across the  other Islands.  No major surges of
tropical moisture are expected over the next week.
