The Hawai`ian islands will remain under the control of a broad
588-dm upper ridge which confines the active and progressive
mid-latitude pattern well to the north. This will ultimately keep
all discernible frontal boundaries out of Hawai`i throughout the
period. The surface pattern is forecast to maintain surface
ridging to the north and east which will support persistent
east-southeast trade winds. Models suggest an enhancement in these
winds by the middle of next week with guidance showing 30 knots of
flow. In terms of precipitation, it should be rather quiet given
the more diminished moisture content with precipitable waters in
the 0.75 to 1 inch range. Expect spotty showers and thunderstorms
developing in the presence of sufficient heating and over the
usual elevated heating sources.
