The global numerical guidance continues to indicate that a trough
will repeatedly reload throughout the next week well to the east
of Hawai'i, keeping a dry, generally northeast flow across the
state. Deep-layer tropical moisture should be shunted off well
south and west of the islands. Very little precipitation is
expected, with many areas seeing no rain whatsoever. Even the
normally wet terrain of the Big Island may not net more than an
inch or so. At the very end of this forecast period--around 00Z
Thursday December 11--the ECMWF shows that there may be enough
retrogression of the longwaves to allow a more direct approach of
a cold front from the north.
