The latest ensemble means are in good agreement on an amplifying
upper trough and evolving upper low to the northeast of the
Islands through this weekend and into early next week, and a col
trying to develop over the state as the subtropical upper ridge
breaks down some.  This will support a meandering stationary front
that would likely be over the central and northern Islands, and
the guidance suggests a surface low will probably form near 30
degrees north and slowly drift west, along with the frontal
boundary, through the middle of the week.

In terms of sensible weather, light to occasionally moderate
trades can be expected through the weekend, and then lighter and
more variable flow for the first half of the week with the col in
place and the frontal boundary nearby.  A more steady easterly
flow resumes by the end of the week.  The mainly terrain favored
showers can be expected most days, but no major rainfall events
are currently anticipated over the upcoming week.
