Surface high pressure situated northeast of the state is expected
to weaken my midweek as a relatively strong cold front settles in
near 30 degrees north.  A weaker pressure gradient will become
established across the Islands by the end of the week with the
cold front lurking north of the state.  Trade wind flow should
abate compared to the ongoing windy conditions based on the latest
model guidance.  By the weekend, the ensemble means are picking up
on a surface low developing near 35 degrees north, with the GEFS
mean slightly north of the EC mean.  It currently looks like the
majority of the heavier rainfall from the front and the surface
low should remain well to the north of the Islands.
