As the remnants of Ema is expected to dissipate well to the
northwest of Hawaii, models show excellent agreement that moisture
from a cold front will dip southwestward across the western
islands of Hawaii on Wednesday.  Some increase in shower
activities along with the possibililty of a few thunderstorms is
expected over the western islands on Wednesday as a mid to upper
level low is forecast to develop.  For the remainder of the week,
a gradual decrease in rain chances is expected as the disturbance
moves west of the area and drier air from the subtropical high
pushes in.  This will favor a return of increasing island trades
with modest daily windward terrain-focusing showers under a
re-emerging ridge aloft.
