The upper level low/inverted trough initially passing over and
west of the state will promote a wet pattern from now into the
first part of the weekend.  With only minor detail differences the
GFS/ECMWF and GEFS mean agree on an axis of very high precipitable
water values passing over the area, 2-2.25 inches or so which
correspond to standardized anomalies that may reach or slightly
exceed the 4-5 range.  After Saturday expect a gradual but steady
drier trend through midweek.  By next Friday there is potential
for some moisture originally associated with T.S. Orlene to begin
moving into the eastern islands.  There now appears to be somewhat
better agreement on timing of this moisture, compared to yesterday
when it was noted that the GFS was on the faster side.  Overall
expect trades to be in the moderate range.  Winds may be slightly
stronger from now into Sunday or Monday versus later in the period.
