Progression of systems along and north of 25N latitude will
provide some day to day variability in trades.  One surface high
initially north/northeast of the islands will track rapidly
eastward while another high will weaken by the time it reaches
north of the area Sat.  Winds may have a more southeasterly
component in the Sun-Tue time frame with the combination of high
pressure centered over the eastern Pacific and a front off to the
distant northwest.  Models/ensembles do not expect this front to
reach the islands but trailing high pressure rapidly progressing
along 30-35N latitude should bring a return to somewhat stronger
and more easterly trades by Wed-Thu.  Primarily windward focused
showers should remain on the light side as precipitable water
values remain around an inch.  Also an east-west oriented ridge
aloft through the weekend will likely evolve toward a closed high
to the northeast of the state but still keep heights over the
islands fairly high.
