Models show excellent agreement that a well-defined cold front
will move across the Hawaiian Islands Friday night into the
weekend.  The associated shortwave energy emphasizes the best
potential for heavy showers to move through the western part of
the island chain on Saturday before the main energy lifts out to
the northeast on Sunday.  Overall the guidance displays better
than average consensus for the heavy rainfall threat with even the
GEFS/ECMWF means producing fairly high rainfall totals in the 12z
Saturday to 12z Sunday time frame.  Behind the front, slight
ridging is indicated before a broad and less-defined front
approaches on Tuesday. This front is forecast to slow down and
become nearly stationary across the southern part of the island
chain by the middle of next week.  Expect rainfall with this front
to be much lighter than with the first front.
