The ensemble means are in good agreement that a closed upper level
low will develop near 35N, and drop southward to near 28N by
Thursday morning near the far western islands.  Meanwhile, an
upper level ridge will remain in place near 150W and this will
cause the upper low to lift to the northeast and evolve into an
open wave by Saturday.  A second trough will likely develop
farther to the west near 175W by late Sunday.  The Trades should
generally be east-southeasterly and lighter through early Friday
as the surface trough helps to weaken the pressure gradient some,
and then become moderate by early next week as the surface high
rebuilds to the north.  With the exception of the far western
Islands that may receive more widespread rainfall, typical trade
wind driven showers should be the norm through this forecast
period.
