No significant changes to the weather pattern affecting the
Hawai`ian island chain the next 7 days. The mid-latitudes will
continue to feature numerous progressive shortwaves with none of
these systems impacting the state through next weekend. Models
continue to advertise an expanding 594-dm mid-level ridge centered
over the International Dateline which will be the dominant feature
to hone in on. At the surface, a gradual increase in the
anticyclone strength will enhance the pressure gradient across the
region which favors an increase in the climatological trade winds.
Many solutions favor sustained low-level winds up to 20 knots with
locally higher gusts. This will be accompanied by a slight uptick
in shower activity although the coverage should be somewhat
limited by the lower end moisture content available per forecast
precipitable water values. The best focus should be across regions
of upslope flow and local mesoscale convergence boundaries.
